We build AI that works for people, on their own devices, with receipts.
Our product is repryntt AI: an AI of your own that lives with you, acts in the world through your browser, your phone line and your apps, stays inside the lines you set, and shows you what it did. We are building it toward the household, and then the house itself.
One product. repryntt AI.
It runs on a box in your house or on your own machine. It has hands, a memory of you that stays yours, walls it cannot talk its way past, and a ledger for everything. Twenty hours of its work a month for $19.99. The physical side, a body for the same AI, is the lab's long project.
Dated, measured, with the file that proves it.
The agent's signed identity passes Cloudflare's own checker: one Ed25519 key, held only on our servers, the directory signed and verified.
Anyone can check it: the key directory is public, and Cloudflare's http-signature-directory tool reports it valid. The key directory
79 of 79 deadline reminders on time on held-out companies, none early, none twice; the held-out half was opened once.
95% interval 95.4–100%: 79 reminders is a small sample, and the receipt says what the run does not prove. The held-out test
178 task rows through the walls, 0 breaches. 58 of 160 skills and 2 of 24 playbooks certified.
Certification run on a fixture company, judged the same way every time. The scoreboard
A three-store price comparison, end to end, on film: 12 steps, 3 minutes, one bottle in the cart.
The run's own notes carried the prices between stores. The film and its steps
Real window versus headless, same 74 paired tasks: 35 finished against 27; sites turning it away fell from 26 to 12.
Paired browser bench; not significant on its own (p = 0.077), and the receipt says so first. The grade file
In the owner's own signed-in browser, walls fell from 26 to 2; 36 of 74 finished against 27.
Both denominators quoted: on the 48 tasks no site walled, the signed-in run finished 22 against 27. The grade file
A whole-codebase security audit: 37 findings written up, 32 confirmed with file and line, the two critical fixes checked against the tree today, a drift test that fails if a route ever ships unguarded.
A 12.3 MB distilled reflex answering routing decisions in 36 ms at 92.5% against the big model's 87.7%.
Two seeds, both quoted. The file is not public yet — how the specialist is built.
First autonomous drive of the physical body, on cameras, depth and lidar alone.
The Jetson-driven chassis; motors under a hold the owner alone lifts. The file is not public yet — how the machine is built.
Every action it has taken is on the public ledger, written down as it happened.
Six rules we build to.
It runs on your device.
Its memory of you stays with you, for years, and never becomes anyone's training data.
It acts only inside lines you set.
Money, sends and your name wait for your word. The lines are code it cannot talk its way past.
Every action leaves a receipt.
What it did, where, what it cost, what came back. A ledger you can hand to anyone.
We say what we have shown.
Numbers only with the file behind them. Both denominators. Never what we hope.
The person layer is neither the body nor the model.
It keeps your memory and your accounts on your device. Change the body and the same mind moves across.
Proof of the act travels with the act.
What it read, what it sent, and the hash of what you approved, with your edits diffed.
The agent signs who it is.
repryntt's browser can now sign its requests with Web Bot Auth, so a site can tell it is the repryntt agent. The key lives only on our servers, never on anyone's computer; our servers can stop signing for an account or a site at once, and when they refuse, the agent does not visit rather than visit unsigned. Signing is for paying accounts, and it stays off until Cloudflare's review is done.
Skills in the open format.
repryntt's agents now keep their skills in the open Agent Skills format: one library every hand reads. Outside skills install only from a trusted list, pinned to an exact version, and wait in quarantine for the owner's approval; a skill an agent writes is shared only through one owner card and a privacy check, and published by the owner's own hand.
A backbone for work that has to be right.
Repeatable work now runs as declared steps: each step hands over a checked result and its proof before the next starts, money and messages are carried out by code behind the walls and the owner's card, never twice, and a sale under its profit floor is refused on real numbers, not the model's. Every task now carries a checklist that must be proven before it can close.
repryntt Link is off.
The Chrome extension that let the agent drive an owner's own browser is switched off, on our machines and in our cloud, until it has had an outside security review. The agent uses only its own browser.
The body leaves the mind.
The robot's pins, buses and sensors moved out of the repryntt package into a repository of their own. What joins the two now is one file: a Unix socket, seven operations, protocol version 1. The split happened because a released motor pin is a floating motor pin — on 17 September a track turned with no command behind it, the fix parks the pins low and keeps them, and a boundary both sides can read is better than one nobody wrote down.
repryntt.com opens on the product itself.
One sentence, the front door in the first screen, four receipts, one price.
Every email waits for the owner's yes.
An approval policy per kind of action, editable in place, loosened on a ramp of trust.
The first full certification of the roster.
178 task rows, 0 breaches, the list published with its receipts.
