The story
Turn your Instagram DMs into an autonomous AI persona that texts like a person. The persona is the easy part: the hard part is everything around the words, when to answer, how long to take, how to split a thought into messages, so that nothing about it feels like a bot.

Timing is the persona
A bot gives itself away by answering instantly, every time. A person answers fast while you are both in the conversation, takes a few minutes after a pause, and much longer if you wrote an hour later. So the delay before a reply depends on how long it has been since your last message, and every delay is drawn at random inside its range.
- you are both in the chat, a reply within 20 seconds7–11 s
- a normal back and forth7–20 s
- you come back after more than 10 minutes1–5 min
- you come back after more than an hour10–15 min
- someone writes for the first time10–30 s

Listen
New messages are collected per person. If you send three short ones in a row, it waits for 10 seconds of quiet and reads them as one.

Wait
The reply is scheduled for later, by the rules above, instead of being sent now.

Answer
When it is due, a pool of five workers sends it, so typing to one person never blocks another. A long reply is split into several messages, each with a typing pause as long as the text.

Remember
Every handled message is saved, and messages still in flight are tracked, so a crash or a retry from Instagram never produces a second reply.
Where Bea started
This bot, and the Telegram one next to it, are where Bea started: the first version of the persona that later became ProjectBEA. The ideas that survived are visible there too, like reading a burst of messages as one turn instead of answering each line.
