What it helps you remember

Remember people, promises, and next steps.

Use your Dossier after a conversation to save what someone said, what you promised, and what you need to ask next time.

Before a call

See what you need to remember before you answer.

Your Dossier can remind you what the person said last time and what you promised to do.

Here is an example of a reminder before Hannah calls.

Before you answer
  • Her dad's surgery was the 14th — you haven't heard how it went.
  • You still owe her Marco's landlord contact.
  • Theo started school two weeks ago.

Based on the voice note saved after your last conversation.

Privacy

You choose what your Dossier holds.

Your Dossier may contain personal information, so you control what goes in and what gets deleted.

  • You decide what's in it. Your Dossier only holds what you choose to brief. Nothing is gathered in the background.
  • Delete anything, anytime. Remove a memory, a person, or your whole account — and it's gone.
  • Your information is not sold. What you keep is never sold, rented, or handed to anyone else.
  • Open about the AI. Briefs are read by AI to sort them. How your words are handled is written down, in plain language.
Point of view

AI agents need saved personal context.

Dossier's view is simple: AI agents work better when they can use the people, promises, decisions, and preferences you have already saved.
