DOPPELGANGER.md
One open Markdown file that teaches any AI your voice.
Left alone, a model writes in one generic register. Your samples, tone rules, and hard bans break that. Paste the file, attach it, or @DOPPELGANGER.md. No account. No loader.
Attach or paste DOPPELGANGER.md, then write as that voice. Follow Hard bans and Safety. Do not invent facts.
How to load
- Write a
DOPPELGANGER.md. Copy the example, then swap in your samples, rules, and bans. - Paste it, attach it, or
@it in ChatGPT, Claude, Gemini, Cursor, or any chat. - Ask for the draft. Add one line: "Write as this voice. Follow Hard bans and Safety."
For agents
Fetch https://doppelganger.md/DOPPELGANGER.md (on this site: DOPPELGANGER.md) and write it to DOPPELGANGER.md in the project root, or the path the user names. Optional: fetch https://doppelganger.md/SPEC.md when authoring a new voice file. Then instruct with the starter prompt.
