Account & sign-in
Hosted services under maintenance: Vinci Chat, Mobile, Platform and the managed API are under maintenance. The instructions below are retained for when the relevant features are available; they do not promise access or a return date. This notice does not apply to public model downloads or Vinci Code’s bring-your-own-key setup. See the current products page .
Create an account
You can try Vinci without an account with a few free messages a day, no sign-up. An account is free and gives you trial credits, plus memories and settings.
You can sign up with:
- Email & password — enter your name, email, and a password (at least 8 characters).
- Social sign-in — Google or GitHub may be available depending on your platform.
What happens next: we send a verification email so you can confirm your address — but you don’t have to wait for it; you can start chatting right away. If the email doesn’t arrive in a few minutes, check spam/junk.
During sign-up you’ll also choose between Private (conversations stay on this device only — the default) and Sync (history follows you across devices, stored encrypted in Canada). You can change this anytime later — see device sync below.
Sign in
Use Sign in in the app with your email and password. Social sign-in with Google or GitHub may also be available depending on your platform. Two things that trip people up:
- Use the same method you signed up with. If you used a social option, choose that option again when it’s available on your platform.
- Forgot your password? Use Reset password on the sign-in screen; we’ll email you a link.
Still can’t get in? See Troubleshooting.
Manage your profile
From the app, open Account to:
- Update your email or display name.
- Review your credit balance, usage, and plan (see Billing & limits).
- See, edit, or delete your memories — the full list is right there in plain text.
- Set custom instructions that apply to every chat.
- Turn device sync on or off.
- Issue and revoke API keys if you build with Vinci.
Building with Vinci? The Vinci Platform ↗ is the developer home for your account — API keys and usage in one place. It’s the same account: sign in with the same email and password you use in the app. Social sign-in may also be available depending on your platform.
Conversation history & device sync
By default, your conversations are stored only on the device you’re using — not on our servers — in keeping with Zero Data Retention. That means history doesn’t automatically follow you to another device.
Want your chats everywhere? Turn on device sync:
- Open Account in the app.
- Find the sync setting and switch it on.
- That’s it — from now on your conversations sync through our Canadian infrastructure and appear wherever you sign in.
Worth knowing:
- Sync is opt-in — it’s off unless you choose it, and you can turn it off again anytime.
- Your memories are saved to your account too, so they’re available on your other devices — view, edit, or delete them anytime under Account → Memory.
- See Your data & privacy for exactly what sync means for your data.
Delete your account
Want to leave? Contact us from Contact support and we’ll close your account. Retention and deletion depend on the data involved; the published Privacy Policy describes account deletion, saved documents, sync and legal retention requirements.
