For everything you send with AI's help
Put your name on what you send.
AI can draft every word. Avow proves to the person on the other end that you read it, understood it, and stand behind it. Signed on your phone, with your face, bound to the exact text.
Authorship-neutral by design. Avow never asks who wrote the words.
Everyone sends AI text now. Nobody can tell who read it.
The receiver pays
A prompt takes ten seconds. Reading the output takes ten minutes. When senders stop reading, the cost moves to whoever opens the message.
Polish is no longer a signal
A careful message and a forwarded draft look identical. The old cues for effort, structure, tone, spelling, now come free with the model.
Nobody owns the claims
"The AI wrote that part" is becoming an excuse. Receivers need to know who will stand behind a number, a promise, a decision.
How it works
One minute on your phone. A badge your reader can trust.

Finish your draft, however you like
Write it yourself, with a copilot, or let an agent draft the whole thing. Click Avow next to Send. Nothing on your computer can complete the next steps for you.

Your phone shows the exact text
The Avow app fetches the message by its fingerprint and shows it in a reading view. What you see is what you sign. No desktop, and no desktop agent, can swap it.

Answer what your reader would ask
Two or three questions, generated from the text by a neutral service: the ask, the deadline, the reasoning, the consequence of doing nothing. Sixty seconds. Easy if you read it.

Face ID seals it
A key in your phone's secure hardware signs the text, the questions and your answers together. The avowal travels with the message.
What the receiver sees
Not a checkmark. Your answers, first.
The proof of effort is also the most useful part of the message. Readers see the human's answers before the body, and know exactly which text they cover.
Before you read, Dorin answered:
- What do you need Maria to decide, and by when?
- Approve the switch to vendor B by Friday.
- Why vendor B rather than staying with A?
- B is cheaper over three years and already SOC 2 certified.
- What happens if nothing is done?
- We auto-renew with A at +18% in November.
Hi Maria,
Following up on last week's review, I'd like to propose moving our document pipeline from vendor A to vendor B ahead of the November renewal…
Why it holds
Built for a lazy adversary, not a malicious one.
Avow doesn't try to make faking impossible. It makes the honest path the shortest one.
Authorship-neutral
It never matters who or what wrote the words. Non-native speakers, people with dyslexia, anyone using AI to think better: all equal. Avow attests to understanding, not typing.
The phone is the air gap
Desktop agents can click any button on a desktop. They can't tap your phone. Questions appear only there, and only your biometric releases the key.
Nobody grades their own exam
Questions are generated by a neutral service after the text is committed. Your AI can't pick softballs, and the exact questions are sealed into the signature.
Bound to the bytes
Content hash, questions, answers, timestamps and device attestation are signed together. Edit the message after avowing and the badge turns into a warning.
Friction scales with stakes
A two-line reply is not a contract.
Read the full text on your phone, Face ID. For short, low-stakes messages. Proves a human read it.
Read, answer two or three receiver-style questions, Face ID. The default for anything longer than a few paragraphs.
Read, then explain the message in your own voice for twenty seconds. For decisions, contracts, anything acted on without a follow-up call.
Email first. Every agent output next.
As agents act on people's behalf, every receiver of agent output wants the same answer: did a human look at this before it left? The same signed avowal works wherever text travels.

Questions
Does Avow stop me from using AI to write?
No. That's the point. Use whatever helps you write well. Avow only asks you to read the result and answer for it. It never reports how much of a message was generated.
Can't someone paste the questions into another AI?
They can try. The questions reference specifics of the text, the window is sixty seconds, and the receiver sees how long the answers took. For a lazy sender, reading the message is faster than gaming it. Avow is not designed to stop a determined fraudster, and says so.
What does the receiver need?
Nothing. Every avowed message carries a verification link that shows the signer, the timing and the answers, and lets the receiver check the text against the signature in their browser. With the Avow extension, the badge and answers appear inline above the message.
Who sees my message?
Your phone fetches the committed text to display it, and a question service reads it once to generate questions. The text is deleted after you sign. Organizations can self-host the question service, and an on-device option is planned.
Is this a signature in the legal sense?
It is a cryptographic signature from a key in your phone's secure hardware, released by your biometric, over a specific text and your answers about it. Whether that carries legal weight depends on your jurisdiction and context. It certainly carries social weight.
AI drafts. You avow.
Avow is in development. If you receive more than you can read, or send more than you'd like to answer for, we'd like to talk.
