Everything else it does
The most helpful member of the group
Whether you use it in a group or by direct message, Agent One becomes more useful as it learns your preferences and context.
Speaks everyone's language
Ask in Hindi and receive the answer in Hindi. Your friend asks in German and gets German — in the same conversation. Over 100 languages, no language setting required.
Memory that lasts
It can remember the preferences, projects and people you ask it to remember. Come back next month and it still knows. No repeating yourself.
Real-time web search
Ask about current events or information that may have changed recently. It searches the web and gives you a clear answer in plain words — not just a list of links.
Reminders that ping you
Say "remind me in 2 hours to call the dentist" and it does. One-off, daily, weekly — for you or the whole group.
Understands images, voice and documents
Send a photo and ask "what's this?" Talk instead of typing. Drop in a PDF and ask questions about it.
Create simple websites by chatting
Describe what you need, review the result and request changes in plain language.
No credit card required

FAQ
Questions
What exactly is Agent One?
Agent One is an AI assistant that works in your group chats — it lives inside Telegram and gives each group its own memory and personality, something ChatGPT can't do. It also handles your DMs: remembering what you tell it, searching the web, and sending reminders. Just message it like a friend.
Does it speak my language?
Almost certainly. It understands and replies in over 100 languages — Hindi, German, Indonesian, Swahili, Thai, Turkish, Spanish, French, and many more. In a group, it answers each person in the language they wrote in, automatically. There's no setting to configure.
Do I need to install anything?
No. If you already have Telegram, you're ready. After signing up, you tap one link to start chatting. Adding it to a group works like adding any other member.
How is this different from ChatGPT?
The biggest difference: group chats. Add your assistant to any group — a family chat, a project team, a friend group — and everyone can talk to it. ChatGPT can't do that. It can also retain useful context over time while keeping each group's memory separate, send proactive reminders that ping you at the right time, and it lives right in Telegram — no app to switch to.
What AI model does it use?
Agent One uses the latest AI technology, which we upgrade regularly. It's fast, capable, and great at conversation, reasoning, and following instructions.
Is there a message limit?
Free accounts include 50 messages per day and 1 group chat. Personal includes unlimited everyday messaging (subject to fair use) and up to 5 groups. We'll always tell you clearly if you're approaching a limit — no surprises.
Will you support more messaging apps?
We're focused on making the Telegram experience great right now. We'd love to expand to other platforms in the future — stay tuned.
How do I cancel?
Cancel anytime from your Stripe billing page. No questions, no hoops. Your assistant stays active until the end of your billing period.
How does it work in group chats?
Add your assistant to any Telegram group. It responds to all messages by default, or toggle @mention mode so it only responds when mentioned. Each group gets its own separate memory.
Can I change my assistant's personality later?
Yes! Type /settings in your chat anytime to change your assistant's name, emoji, or personality. Pick from our templates or write your own description. Changes take effect on your next reply.
Is my data private?
Yes. Your conversations are between you and your assistant. We do not use them for advertising, sell them to third parties, or use them to train our AI models. Access is restricted and only permitted when necessary for security, support or legal compliance. Your assistant's memory is stored securely and is only available within the relevant account or group conversation.
