Your phone runs on an AI built to take your agency. Fiduciari is an AI built to give it back.
Your thoughts are your own to form. Your attention is your own to spend. Your actions are yours to choose — not something a feed decided for you while you weren't looking.
This isn't a privacy problem. It's a breach of trust.
Every feed you open is run by an AI optimized for one thing: keeping your attention longer than you intended to give it. It decides what you see, what you feel urgent about, and who you think is talking to you. That's not a side effect — it's the product. Fiduciari exists to put an AI back on your side of that fight: one whose only job is to act in your interest, the way a fiduciary is legally required to act in yours.
Mark Zuckerberg's own testimony puts the share of your feed from accounts you don't follow on track to roughly double from here. The algorithm isn't drifting toward strangers by accident — it's being tuned toward them.
An AI fiduciary owes you four duties
A human fiduciary — a trustee, an attorney, a doctor — owes their client specific, named duties: loyalty, candor, confidentiality, care. Fiduciari is built to owe your mind the same four, mapped onto the four places your agency actually gets taken.
Agency over your attention
removes the mechanic, not the contentInfinite scroll, autoplay, badges, and red dots aren't content — they're machinery built to extract more time than you decided to give. A loyal fiduciary doesn't profit from your compulsions, so Fiduciari removes the mechanics themselves, independent of what you're looking at. Scrolling ends. Video doesn't chain itself forward. Nothing blinks at you to come back.
Agency over your thoughts
discloses — never decides for youSensationalized headlines get rewritten to neutral, factual language before they reach you. Social content gets a tag-first system — provenance signals, a friction tag on engagement-engineered posts, a narrow flag on specifically disputed claims. Fiduciari never asserts something is false and never hides your ability to see the original. A fiduciary discloses. It doesn't censor.
A fiduciary can't let one feed decide what's true. It can make sure you're the one deciding, with the manipulation stripped out of the way you're being shown it.
Agency over your identity
privacy, in service of agency — not the pitch itselfIf an app can still profile you, it can still steer you — agency and privacy aren't two products, they're one. Fiduciari blocks tracking on-device, defeats the price discrimination that charges you more because of what's known about you, and quietly reduces the signal strangers and advertisers get — which, as a side effect, tunes social algorithms toward people you actually know.
Agency over your life
an exit, not another feedA fiduciary looks out for your actual wellbeing, not just the transaction in front of you. Fiduciari notices when the phone is the whole day — especially for people working from home, between jobs, or just isolated — and nudges toward something concrete and real nearby: a pickup game, a library event, a council meeting. Not a better feed. A way off the phone entirely.
You're not imagining this.
If you've felt like something new is happening — like the pull is stronger, the persuasion more precise, the sense that you're arguing with something that already knows exactly which version of the argument works on you specifically — that's not anxiety getting the better of you. It's published, peer-reviewed research, and it landed in 2025, not some distant future.
"As AI scales and synthetic content floods the internet, verified human connection becomes the scarce resource."
The mission
- We give people back agency over their own attention, thoughts, and actions.
- We make disclosure the default — never deciding what's true on someone's behalf.
- We treat isolation as a cause of what people fall for online, not just a symptom of it.
- We protect what's most human, especially for a generation growing up inside AI tools more persuasive than any before them.
An on-device cognitive fiduciary — four duties, one layer, working for you instead of the platforms your phone was built to serve.
See it, don't just read about it
A real phone, screen by screen — News, YouTube, a notification, Nearby, delivery pricing, and Facebook with the duties switched on.
This is the actual interaction model, not a mockup described in words: what a rewritten headline looks like, what a tag-first flag looks like, and the live feed-composition read-out that shows exactly how much of a feed is really from people you know.
