FAQ
What is Tether AI?
AI assistant that remembers and acts for you. Reminders, routines, the people and details of your life — Tether remembers it all, by text in SMS and Telegram. Reminders and routines are just memory with a time on it. Every memory is yours to read, edit, or delete.
How does Tether remember things differently?
Most AI tools forget after each conversation, or hide memory in a black box. Tether saves the facts you share — your preferences, the people in your life, what you're working on — and carries them across every conversation, so its memory compounds with use. Every saved fact is browsable and editable in your dashboard. You see exactly what Tether knows about you, and you can fix anything we got wrong.
Who is it for?
Anyone with too much to keep track of. Founders, sales leads, consultants, working parents — the common thread is having more on your plate than your brain can hold.
How is it different from ChatGPT?
ChatGPT is a stateless chatbot — it forgets after each conversation. Tether keeps persistent memory across all your sessions, runs proactively on your schedule (routines, reminders, follow-ups), and lives in your text app. It's not for essays or code — it's for managing your day.
Does it work with Google Calendar and Notion?
Yes to both. For Google Calendar, Tether reads, creates, edits, and deletes events — find free time, block focus time, or just tell it in plain language. Notion connects the same way: search your pages, read them, and create new ones by text. Each takes one tap via a magic link Tether sends you in chat. Outlook is on the roadmap.
Can Tether remind other people, not just me?
Yes — with their consent. Connect with someone (they tap once to confirm), then ask Tether to text them reminders on your behalf. Every reminder is clearly labeled “From [your name],” and they can stop anytime. Handy for nudging a parent, partner, or teammate without nagging.
Do I need to download an app?
No. Tether runs entirely through SMS and Telegram, which you already have. Just text Tether to sign up — that's it. The optional dashboard at trytether.ai lets you browse and edit your memory; you sign in with a magic link sent through your messaging channel.
Does it write code or essays?
No. Tether stays narrow on personal admin so it does that job exceptionally. For coding, use Claude Code or ChatGPT. For writing, use Claude or ChatGPT.
