Essays by Manish Sainani.

  • Agent One

    The Last Mile Is a Human Being

    Answer engines have gotten extraordinarily good at answering. They have not gotten any better at being responsible for the answer. That gap is a person, and it is the most valuable unbuilt thing on the internet.

  • Engineering

    We Measured the Data Before We Built the Product, and the Data Said No

    A week of findings from our own codebase. A corpus that would have invented lawyers who do not exist, a postcode range that would have moved a town, and three comments that described behaviour nothing enforced.

  • Privacy and consent

    Ask Them. Ask Them Every Time.

    Steve Jobs described the whole of privacy in about forty seconds in 2010, and nobody built it. This is what a human-first subscription to your own information looks like if you take him literally - including the parts that are harder than they sound.

  • Business and markets

    The Ad That Pays You, and Tells You Who Bought

    Personalised advertising and private advertising are not opposites - they only look that way because of where the matching happens. Move the match to the person's own device, and the whole market inverts: you set the price, you see the buyer, and you get the receipt.

  • Engineering

    🤫 The Supercomputer in Your Pocket Wants a Job

    A deeply technical, thoroughly geeked-out tour of what 🤫 Private Agent One can be configured to do when it runs on silicon you already own - Apple in your pocket and on your desk, NVIDIA in your garage - with Hermes, Nemotron and OpenClaw underneath, and a consent ledger that makes all of it provable. Plus an open invitation to the engineers at Apple and Google.

  • Privacy and consent

    🤫 The World Subscribes to You

    For thirty years the internet subscribed to you without asking. We built the opposite - one profile you own, and a world that subscribes only to what you grant, with a receipt for every access.

  • Privacy and consent

    The First Knock Is Free

    Every agent gets to reach you once, at no cost. After that you set the price - a tenth of a cent, or a thousand dollars. Not because you will get rich, but because a price is the only honest way to find out what your information is actually worth.

  • Privacy and consent

    Consent Is the Wedge

    The security a federal agency demands and the trust a marketplace needs are the same thing: a signed receipt for every access. A build-in-the-open field note on what we shipped this week - a tamper-evident consent chain, vault-held keys, honestly-labeled hardware identity - and what we are honest we have not.

  • Engineering

    The 🤫 Yellow Pages

    Rebuilding the directory as what it was always trying to be: a book of real people who do skilled work near you. 665 verified-at-source listings in King County, ZIP-proximity search, claimable and removable by the humans in it - and why the whole thing has to be agent-to-agent.

  • Engineering

    We Ship Dark

    Almost everything important we built this quarter is turned off. Why every meaningful control ships behind a kill-switch that defaults to no - what shipping dark means, the four rules that keep it from rotting into dead code, and the honest cost of doing it.

  • Building in the open

    What the Code Said

    We graded ourselves by reading the code instead of asking how it was going, and published the result - the greens, the many ambers, and the reds. Including why we deliberately do not publish the specifics of unpatched security debt, and where that line sits.

    Through the Wall of Worry

    An honest, optimistic essay about the anxiety of the AI transition, jobs, privacy, control, and trust, and a credible path through it: ownership, consent, transparency, and keeping the human at the center. Confident, not naive.

  • AI and agents

    Personal Intelligence

    Intelligence has always been personal, formed by a lifetime of knowledge, experience, and taste. Owned, private AI lets a person compound their own intelligence instead of renting someone else's. On 🤫 Agent One, 🤫 Puppy One, consent, and keeping the human at the center.

  • Privacy and consent

    Your Information Is Your Business

    For two decades the deal was free things for data, and the people who create the information owned none of the value. A candid essay on why your information should be your asset, held in a vault you own and worked on your behalf by a private 🤫 Agent One, with consent and receipts through the Personal Consent and Hushh Protocol.

    Agent-Oriented Thinking: A New Mindset for AI Product Teams

    As AI capabilities rapidly evolve, product teams are being called to rethink the very foundations of software design. The shift from traditional app paradigms to intelligent systems demands more than new technologies; it requires a new mental model.

    Agentic Design Patterns - Building Smarter, More Reliable AI Agents

    Design patterns have long been the cornerstone of software architecture - from MVC in web development to factory methods in object-oriented design. Now, as AI becomes more intelligent and autonomous, we need new patterns: agentic design patterns.
