The story
A Telegram bot that does not feel like a bot. It runs on Google's Gemini, but the point is not the model: it is the rhythm. It answers the way people text, in several short messages, with a typing pause before each one.
- characters per second, the typing speed it pretends to have
- 15
- random variation on every pause, so it is never the same twice
- 20%
- longest pause before a message
- 4 s
Texting, not answering
A normal bot sends one block of text, instantly. People don't: they send a few short lines, and you see "typing…" before each one. So the system prompt asks the model to write a thought as separate lines, and the bot turns every line into its own message, each preceded by a pause as long as it would take a fast typer to write it.

Listen
It answers in private chats, and in groups when someone mentions it.

Think
The conversation so far, kept per chat, goes to Gemini 2.0 Flash, or any model you set, together with a system prompt you can rewrite.
- 3
Split
The answer is cut at every line break: each line will be a message of its own.
- 4
Type
For each one it shows "typing…", waits the length of the line at 15 characters a second, give or take 20% and never more than 4 seconds, and sends it.
Where Bea started
This bot and the Instagram one are where Bea started: the first version of the persona that later became ProjectBEA.
