Same Brain, every tool

Ask in Claude. Ask in ChatGPT. Ask by text. Same answer.

Your Brain is one link. Paste it into any AI tool and it knows what you know. Switch tools whenever you like — nothing to re-explain.

Questions

Straight answers.

Is my data private?

Yes. Your memories are encrypted with a key unique to you, we never use your data to train AI models, and people in your group chats can never read your Brain — Synnc only uses what was said in that group.

Does it work on Android?

Yes. Texting works on any phone. Some iMessage features, like reactions and group threads, are richest on iPhone.

What happens on day 7?

Nothing is charged unless you subscribe. If you don't, your Brain pauses and you can pick it up any time.

Can I take my Brain out?

Any time. Export everything or delete your account from Settings.

Which AI does it use?

The best model for the job, automatically. If an answer matters, ask it to think harder.

One Brain. Every AI.
