An AI secretary on Telegram: reminders, meetings and voice notes in one chat

Updated September 24, 2026

Agent OS is a personal AI secretary in your own Telegram bot: it sets reminders from a plain sentence, books meetings into its calendar, sends a morning plan, transcribes voice notes and drafts messages. It remembers what you agreed across conversations. From $29/mo, with the first 3 days free.

What does an AI secretary on Telegram do?

It takes over the small organisational work that usually lives in your head or in a dozen notes.

  • Reminders: one-off and recurring, from a sentence like "remind me tomorrow at 10:00 to renew my insurance".
  • Meetings: "book a call with Andrew on Thursday at 3 pm" — and a reminder arrives 30 minutes before.
  • Morning brief: at 08:30 your time — today's reminders and open tasks.
  • Voice notes: transcription, call notes, tasks pulled from what you dictated.
  • Drafts: a customer reply, an email, a group message — in your tone.
  • Documents: PDF, DOCX, XLSX — summary, deadlines, amounts.

All of it in one chat, no extra app.

How do you set a reminder with an AI secretary?

Type it or say it in a voice note, the way you'd tell a person. The assistant understands English, Ukrainian and Russian.

  • "Remind me in 30 minutes to call the bank."
  • "Remind me on August 25 to pay the rent."
  • "Every Monday at 9:00, remind me to send the report."
  • "Every day at 9 pm, remind me about my workout."

Up to 10 reminders can be active at once, and a repeat can't be more frequent than every 5 minutes. Listing, moving and cancelling work the same way: "show my reminders", "move it to Friday", "cancel". If your time zone is unknown, the assistant asks for your city.

Can an AI secretary manage a calendar?

Yes. The assistant has its own calendar that works right away, with no outside service to connect. You say "book a meeting with the lawyer tomorrow at 11" and later ask "what's on tomorrow?".

An honest caveat: there is no Google Calendar sync today. The integration exists in the code but only switches on once a connection is configured (OAuth), and it isn't confirmed working in production yet. If your whole life already runs on Google Calendar, factor that in.

What is the morning brief?

It's one message at 08:30 in your time zone: today's reminders, open tasks and your remaining credits. The brief is assembled without calling the model, so building it doesn't spend credits.

It's off by default. Turn it on with /morning on or with a button after your first task. If there's nothing to report, no brief is sent at all.

The "Daily planner" skill adds a morning plan and a short evening wrap-up on top.

What doesn't an AI secretary do?

Better to know this before you pay.

  • It doesn't make or take phone calls.
  • It doesn't message people on your behalf — it drafts, you send.
  • It has no internet access: the sandbox is offline, so it can't book a table on a website.
  • It can't see your email or other chats until you forward a message or file to it.
  • It doesn't invent meetings or deadlines you never mentioned.

How does the secretary remember what matters?

After a conversation the assistant picks out lasting facts on its own and shows "Remembered: …" with a "Don't" button. Say "remember: …" and it saves the fact immediately.

That's how it knows your lease renews on the 15th and your accountant changed numbers. All memory is visible in the dashboard, where you can review, export or wipe it.

How much does an AI secretary cost, and how do you start?

For one person, START at $29/mo is enough: 1 assistant and 3,000 credits. If you want the secretary in a shared group with your team, look at BASIC at $49/mo or PRO at $95/mo.

The fastest start is the ready-made "Personal assistant" setup: the daily planner, page-from-voice-note and call-notes skills are already on. Describe the job, sign in with Telegram, and the assistant arrives as a link within a few minutes.

Frequently asked questions

Can an AI secretary on Telegram set reminders from a voice note?

Yes. Send a voice note saying "remind me tomorrow at 10 to call the bank" — the assistant recognises the speech and sets the reminder.

How many reminders can I set?

Up to 10 active at once, one-off or recurring. A repeat can't be more frequent than every 5 minutes.

Does it sync with Google Calendar?

Not yet: the integration is in the code but not confirmed working in production. The assistant has its own calendar that works immediately and reminds you 30 minutes before a meeting.

Can the secretary reply to people for me?

Not in personal mode: it drafts and you send. Auto-replies to outside people exist only in client mode on PRO and above.

Will it message me first?

Yes, if you ask it to: reminders, the 08:30 morning brief, and watch rules you switch on with one sentence. The brief never arrives without your opt-in.

How much does an AI secretary cost?

From $29/mo on START. The first 3 days are free: 150 credits and no automatic charge.
