Most AI chat starts every conversation as a stranger and waits to be asked. Here is what changes when the assistant is yours and knows you.
You explain who you are, and who everyone is, again and again.
It remembers you and the people in your life, from one conversation to the next.
It only speaks when spoken to.
It sends the reminders you ask for, and checks in on its own after a quiet couple of days.
It tells you what you want to hear.
Honest counsel, not just agreement: it tells you what it actually thinks.
One more app to remember to open.
It’s in your web browser, or in Telegram next to the people you already talk to.
Memory
Tell it about your life once. It keeps what matters in its memory: you, the people in your life, the dates and the plans, and brings them up when they help. Mention something you told it before, and it already knows.
Yours
Asto Chat runs on Claude, from Anthropic, on your own Anthropic key, so Anthropic bills its use to you directly. Your key stays on Asto’s private servers and is used only to send your requests to Anthropic. What you send is used to write the reply, and Anthropic doesn’t train its models on it.
Also in Asto Chat
After a quiet couple of days, it checks in, picking up where you left off.
Ask in plain words, and it sends the reminder when the time comes.
Just ask it, for example “no messages after 10pm”, and it turns them on.
Send it a voice note or a photo on Telegram, and it understands it.
It can search the web when a question needs it.
Name it when you sign up, or let it ask you in your first conversation.
Today, Asto Chat works in your web browser and on Telegram. The iPhone app isn’t in the App Store yet.
