Tools for developers and their AI agents
Persephone is a free notepad for Windows that opens almost anything, and a workspace your AI agent can see and drive.
Why Persephone
Section titled “Why Persephone”- One app for every file. Code, JSON, CSV, logs, Markdown, diagrams, archives, plus Word, Excel, PDF and SQLite on demand.
- Your AI agent works in it with you. It opens grids, diagrams and documents to show you results, and it drives the app and the browser.
- Tools built on request. Ask for a dashboard or a viewer, and the agent builds it as a board and tests it.
- Free, open source and local. It runs on Windows and collects no usage data.
