Your Library New

Every prompt starts here. Every prompt stays here.

Promptmark gives every user their own isolated SQLite database. Your prompts don't share tables with anyone else's data — they're physically separated at the storage level. Create prompts in a full markdown editor with syntax highlighting, or import what you already have.

Eight prompt types cover every format: plain text, markdown, XML, JSON, YAML, TOML, code, and chat. Import directly from ChatGPT exports, Claude conversation transcripts, JSON files, or plain markdown. Found a public prompt worth building on? Remix it with one click — the original author gets full attribution.
