  • Why electric motorbikes matter more than flashy EV launches

    Electric cars get the dramatic photos, but electric motorbikes may be the more interesting test of whether EVs can fit real urban life. They are cheaper to buy, easier to park, and closer to the daily economics of riders who count every shilling spent on fuel and repairs.

    The challenge is not only the bike. It is the system around it: charging, battery swaps, spare parts, financing, and technicians who can keep the fleet moving when something breaks.

    That is why the best electric mobility story is not a single launch. It is a network that makes the cheaper choice feel reliable enough to trust every morning.

  • We ran 3 AI assistants through a Nairobi week

    The demos always work. That is their job. So instead of trusting the stage, I spent a normal week in Nairobi leaning on three of the most popular AI assistants, ChatGPT, Gemini, and Claude, for the ordinary tasks I would have done anyway. Drafting messages, working out a budget, getting directions, checking facts, switching between English and Kiswahili the way people actually talk. I was less interested in which is smartest on a benchmark and more interested in which is least annoying when life is normal and the connection is not.

    A note before the findings: this is a field test, not a lab. I used each assistant as a regular person would, on a phone, on regular data, over one week. Your mileage will vary with the version, the day, and your questions. With that said, here is what held up and what did not.

    ## Everyday writing and thinking

    For drafting and tidying up text, all three were genuinely good, and honestly close enough that preference came down to tone. Each could turn a rough WhatsApp rant into a polite message, summarise a long document, and rough out a plan. If your main use is writing help, you almost cannot go wrong, and the free tiers are already strong enough for most of it.

    ## Local knowledge, the weak spot

    This is where the gap between the stage and the street showed. Ask about a global topic and the answers were solid. Ask about a specific Nairobi neighbourhood, a local fee, a small Kenyan company, or a current matatu route, and the confident wrong answers crept in. None of them should be trusted on hyper-local detail without a check. They are world-class generalists and shaky locals.

    ## Language and code-switching

    Kiswahili was handled better than I expected, and basic code-switching between English and Kiswahili mostly worked. Sheng and very colloquial phrasing were hit and miss. For formal Kiswahili they were useful; for the way people actually text, results wobbled.

    ## The unglamorous bit: data and connection

    Here is the part no launch mentions. These tools live in the cloud, so they eat data and they need a signal. On a strong connection they felt instant. On a weak one, or when the network dropped, they stalled, and a long back-and-forth quietly chews through a bundle. If you are on a tight data plan, that is a real cost, and it shaped how I used them: shorter exchanges, fewer giant pastes.

    ## So, the verdict

    Treat any of the three as a sharp, fast assistant for thinking, writing, and getting started, and treat all three as unreliable witnesses on local specifics. Use them to draft and to reason, then verify anything local or anything that matters before you act on it. Pick the one whose tone you like, because on the everyday stuff they are closer than the marketing suggests.

  • Gemini Spark review: promising, not quite ready

    Gemini Spark is one of the first personal AI agents built for ordinary people rather than developers, and it is genuinely useful for routine digital chores. But it asks for trust it has not fully earned yet, it costs premium money, and it still needs supervision. Promising, worth watching, not yet worth relying on.

    Google introduced Spark as a personal agent inside the Gemini app: a tool that does not just answer you but goes off and does things, building custom workflows and continuing to work in the cloud even when your phone is locked. After spending time with it, the short story is that the idea is right and the execution is early.

    ## What it does well

    The core promise lands more often than I expected. For routine, low-stakes tasks, organising and triaging, drafting and queuing things up, pulling together information from across your day, Spark can genuinely take work off your plate and keep going in the background. When it works, it feels less like using an app and more like having handed something to a capable assistant. That is a real shift, and at consumer scale it is new.

    ## Where it stumbles

    The trouble is the same trouble every agent has: it acts, and acting means it can act wrongly. A few times it confidently did the not-quite-right thing, which meant I could never fully stop watching, and an agent you have to supervise constantly is only half an agent. It is also early in obvious ways, with rough edges and behaviour that varies. And it sits behind Google’s premium subscription, so you are paying top prices to use something that still asks for your patience.

    ## Who it is for

    Spark is for the curious and the comfortable: people who enjoy being early, already pay for Google’s top AI tier, and have low-stakes tasks they are happy to delegate and double-check. If you want something dependable that you can set and forget, wait. This is a first chapter, and a promising one, but it is not the finished book.

  • Best AI subscription for your money in 2026

    The honest starting point for AI subscriptions in 2026 is this: for a lot of people, the free tiers are already enough. The big assistants give away a genuinely capable version, and unless you are using AI hard every day, you may be about to pay for power you will never touch. So before any recommendation, here is the question to answer: how often do you actually use this, and for what?

    Let us break the market into three tiers and match them to real people.

    ## Free: enough for most casual users

    The free versions of the major assistants now handle everyday writing, summarising, brainstorming, and quick questions well. Cost: nothing. If you reach for AI a few times a week to draft a message, tidy some text, or get unstuck, stay free. You are not missing much, and you are spending nothing.

    ## Cheap mid-tiers: for daily users on a budget

    A new layer has appeared at the low end, with at least one major assistant offering a paid tier at around USD 4.99 a month. For someone who uses AI most days but does not need the absolute top models, this is the sweet spot: more capacity and fewer limits, without the premium price. Best value pick for a daily user who wants more than free but does not want to spend like a professional.

    ## Premium: only if AI is core to your work

    The flagship plans, commonly around USD 20 a month and up, unlock the most capable models and the highest limits. These earn their keep only if AI is genuinely central to how you work, a writer, coder, analyst, or builder who would feel the difference every day. If that is you, the cost is easy to justify. If it is not, you are paying for a professional tool to do occasional chores.

    ## The money math people forget

    Two things matter especially in Kenya. First, most of these prices are in dollars, so the real cost in shillings moves with the exchange rate, and a cheap plan abroad is less cheap here. Second, these are cloud tools, so on mobile they also cost you data. Factor both in before you subscribe. A useful trick: add up what a year of any plan costs in shillings, then ask whether the tool clearly saves you more than that in time or money. If you cannot answer yes quickly, stay on the tier below.

    ## One more option for the technically inclined

    If you are comfortable with a bit of setup, open models such as Gemma and Qwen can be used at low or no cost, and they keep getting better. They will not always match the top paid models, but for many everyday tasks they are more than good enough, and they put a sensible ceiling on how much anyone should pay for the basics.

    ## The bottom line

    Best free: stick with a major assistant’s free tier if you use AI occasionally. Best value: a cheap mid-tier around five dollars a month if you use AI most days. Premium: only if AI is core to your work and you feel the difference daily. Buy the tier that matches how you actually use it, not the one the marketing says you need.

  • Why your phone gets hot when you charge and use it at the same time

    Your phone is doing two hard jobs at once when you charge and use it. It is pulling power into the battery, and it is also spending power on the screen, processor, network, speakers, and apps. That push and pull creates heat.

    Think of it like filling a bucket while someone is scooping water out. The charger is trying to refill the battery. Your game, video call, TikTok scroll, or Google Maps trip is draining it at the same time. The phone has to manage both, and the battery is not the only part getting busy. The chip warms up. The charging circuit warms up. The screen warms up too, especially if brightness is high.

    Some warmth is normal. If you are using mobile data in a weak-signal area, the phone may work harder to stay connected. If you are charging with a fast charger, the first part of the charge is usually more intense. If the phone is inside a thick case, heat also has a harder time escaping.

    The part to take seriously is uncomfortable heat. If your phone is too hot to hold, if charging slows down suddenly, if you see a temperature warning, or if the battery starts swelling, stop using it and unplug it. A swollen battery is not a “wait and see” problem.

    For daily use, the fix is not dramatic. Take off the case during heavy charging. Avoid charging under a pillow or inside a bag. If you are gaming, give the phone short breaks. If you need to use maps on a boda ride or matatu trip, plug in before the battery gets very low, because charging from 5 percent while navigating is harder on the phone than topping up from 40 percent.

    Fast charging is not evil. Modern phones are built to control temperature, slow charging when needed, and protect the battery. But heat still matters. The phone can protect itself, yet your habits decide how often it has to.

    There is also a difference between “hot because I am doing a lot” and “hot because something is wrong.” A phone that warms during a video call while charging is behaving in a way most of us can understand. A phone that heats up while sitting idle, drains quickly, or smells odd needs attention. That could point to a bad cable, a poor charger, a software bug, or a battery that is no longer healthy.

    The cable and charger deserve some blame too. Cheap chargers are not all dangerous, but the truly bad ones can deliver unstable power or fail to communicate properly with the phone. If your phone gets unusually hot with one charger and behaves normally with another, stop using the suspicious charger. It is not worth risking the battery to save a few minutes.

    One practical habit helps more than people expect: charge before the panic zone. Batteries and charging systems are calmer when you top up in the middle of the day instead of waiting until 2 percent, then fast-charging while using the phone hard. You do not need to become obsessive. Just avoid turning every charge into an emergency.

    If you share chargers at home or work, pay attention to patterns. Maybe your phone only heats up with the old charger near the sofa. Maybe it gets warm when one particular game is open. Maybe it behaves normally on Wi-Fi but heats up on mobile data. Those clues matter because heat is rarely random. It is usually the phone telling you which combination is stressing it.

    For parents, this is also worth explaining to children who use phones while charging. The risk is not that every warm phone will explode. That is the dramatic version. The ordinary risk is battery wear, slow charging, and a device that becomes less reliable sooner than it should. A phone is expensive. Keeping it cooler is a cheap form of maintenance.

  • What is an AI agent, really?

    An AI agent is software that does not just answer you, it takes actions to reach a goal you set, with some independence along the way. That is the whole idea in one sentence. Everything else is detail.

    Here is an analogy that holds up well. A chatbot is like a knowledgeable friend you ask a question: you get a good answer, and then it is back to you to do something with it. An agent is more like an intern you hand a task to. You say what you want, and it goes off, makes a plan, uses the tools it has, checks its own work, and comes back when the job is done. The difference is not how clever the answer sounds. It is whether the thing acts.

    In 2026 you are meeting agents whether you sought them out or not. Google’s Gemini Spark is pitched as a personal agent that runs tasks in the background. Anthropic lets teams hand tasks to Claude and walk away while it works. Coding tools now run as agents that write, test, and fix code on their own. The pattern under all of them is the same.

    ## What actually makes something an agent

    Strip away the branding and a real agent usually has four things working together: a goal you give it, some autonomy to decide the steps, tools it can use, and a loop where it plans, acts, checks the result, and tries again if something went wrong.

    If a product can plan a multi-step task, use tools, and recover when a step fails, it is fair to call it an agent. If it just answers questions in a chat window, it is a chatbot, no matter what the launch slides say.

    ## Why the excitement, and why the caution

    The excitement is real. An agent that can quietly handle the boring, repetitive parts of your digital life is genuinely useful, and for a small team it can feel like extra hands. That is why every big company is racing to ship one.

    The caution is just as real, and it is the part the marketing skips. An agent acts, which means it can act wrongly, at speed, and at scale. To be useful it usually needs access to your accounts, your files, or your tools, and the more it can touch, the more a mistake can cost. The sensible posture in 2026 is to let agents handle low-stakes, reversible chores, and to keep a human hand on anything that spends money, sends messages on your behalf, or cannot be easily undone.

    ## The one-question test

    Next time something is sold to you as an AI agent, ask one thing: can it take a multi-step action on its own and recover when a step fails? If yes, it is an agent, and you should think about trust and access before you switch it on. If no, it is a chatbot with a new sticker, and you should not pay agent prices for it.

  • Kenya’s AI rules mean more than paperwork

    AI policy can sound distant until a startup tries to sell a tool to a bank, a hospital, or a county office. Then the questions get practical very quickly. Where is the data stored? Who is accountable when the answer is wrong? Can a person appeal a decision the system helped make?

    Kenya’s opportunity is to keep those questions practical. A rulebook that is too loose leaves citizens exposed and serious buyers nervous. A rulebook that is too heavy can make young companies spend more time proving compliance than proving usefulness.

    The best version sits in the middle: clear consent, clear accountability, room for local experimentation, and enough certainty that builders do not have to wait for rules written somewhere else.

  • Why AI hallucinates, and how to catch it

    An AI hallucination is when a chatbot states something false as if it were true, fluently and with total confidence. The unsettling part is not that it gets things wrong. It is that it gets them wrong in the same calm, polished voice it uses when it is right.

    To see why this happens, it helps to know what these tools actually do. A chatbot is not looking up answers in a database. It is predicting likely next words, one after another, based on patterns it learned from enormous amounts of text. Most of the time those patterns line up with reality, so the answer is correct. But when it hits a gap, a fact it does not have, a source that does not exist, a number it never saw, it does not stop and say so. It fills the gap with the most plausible-sounding words, because that is what it was built to do.

    ## Where it bites hardest

    A few situations produce hallucinations again and again: made-up sources, confident numbers, invented quotes, and hyper-local detail. Ask about a specific Nairobi street, a local law, or a small company, and the odds of a smooth, wrong answer go up, because the model has seen less reliable text about it.

    ## How to catch it before it catches you

    You do not need to be technical to stay safe. Ask for sources, then actually check them. Be most suspicious of exact figures, dates, names, and quotes. Cross-check anything you will rely on. Prefer tools that ground their answers in search and cite real pages. Treat AI as a fast first draft, not the final word.

    This, by the way, is why tecMAMBO does not let AI invent facts in our work, and why a person checks everything we publish. The same standard serves you well: let AI speed you up, but keep the judgement human.

  • Tokens and context windows, why AI forgets

    A token is a chunk of text an AI reads and writes, and a context window is how much of that text it can hold in mind at once. Get those two ideas and a lot of confusing chatbot behaviour suddenly makes sense.

    Start with tokens. AI does not read whole words the way we do. It breaks text into small pieces called tokens, which are often words or parts of words. A short message is a handful of tokens. A long document is thousands. Everything the model reads from you, and everything it writes back, is counted in tokens. That counting is also how most AI tools bill: you pay per token in, and per token out.

    Now the context window. This is the amount of text, measured in tokens, that the model can pay attention to at one time. Picture a desk. The context window is how much paper fits on it. While your conversation is small, everything sits on the desk and the model can see it all. As the chat grows, the desk fills up, and to make room, the oldest papers slide off the edge. That is the moment your chatbot forgets what you said at the start.

    In 2026 these desks have become enormous. Top models advertise context windows of a million tokens or more, enough to hold whole books. That is genuinely useful. But bigger is not automatically better. A huge window costs more to use, and stuffing it with everything can actually make a model less focused, the way a cluttered desk makes it harder to find the one page that matters.

    ## How to get better answers

    Put the important bit close to your question. Summarise long threads. Start fresh for a new topic. Do not over-stuff the prompt with the entire folder unless the task truly needs all of it.

  • Anthropic’s top AI models pulled over a US export order

    Anthropic has suspended access to its two most capable models, Claude Fable 5 and Claude Mythos 5, after the United States government issued an export-control directive. According to Anthropic’s own statement, complying with the order meant turning the two Mythos-class models off for customers while other models, including Opus, Sonnet, and Haiku, kept working normally.

    Here is the plain version of what these models were. In early June, Anthropic introduced a new top tier that sits above its established Opus line, with Fable 5 as the widely released version and Mythos 5 offered only to a small set of organisations. Days later, the export-control order arrived, and the most powerful options came off the table.

    If you use Claude through the app or through everyday tools, this most likely does not change your day. The models ordinary users reach are unaffected. So why pay attention?

    Because it tells you how governments now see frontier AI. The most capable models are being treated less like ordinary software and more like strategic technology, in the same bracket as advanced chips, where a single policy decision can switch off access overnight. That logic does not stop at one company or one country.

    For anyone building on AI in Kenya, there is a quiet lesson in here. If a tool can be switched off by a decision made far away, it is risky to wire your most important work to one top-tier model from one provider. The teams that cope best will be the ones that can swap models without rebuilding everything, and that keep a sensible fallback.

    This is a developing story, and the exact access status for the top models may continue to change. The bigger point is already clear: frontier AI is now part product, part policy question.
