How it works

1

Ingest

Point it at your messages. Import from iMessage, Slack, Gmail, Twitter, Discord, Reddit, Instagram, or GitHub.

$ replicateme ingest --source imessage
Scanning ~/Library/Messages/chat.db... Found 12,847 sent messages Analyzing writing patterns... Style profile saved to ~/.replicateme/profile.json

Analyze

It builds a fingerprint of how you actually write: capitalization habits, punctuation use, common shortcuts, typical errors.

$ replicateme profile
Style Fingerprint ----------------- Avg message length: 31 chars Capitalizes first word: 81% of the time Ends with period: 1% of the time Uses question marks: 17% of the time Uses emoji: 2% of the time Short fragment messages: 58% of the time Lowercase "i" instead of "I": 27% of the time Top Quirks ---------- "im" without apostrophe 843 occurrences "dont" without apostrophe 312 occurrences "thats" without apostrophe 198 occurrences

Generate

Give it a prompt and it writes back in your voice, using your style profile to match your patterns.

Generated 3 variants (quirk: 50%) 1. Yeah im down for that. What day were you thinking? 2. yeah could be down for that. what day were you thinking? 3. yeah im down, what day were you thinking
