Features
Edit real documents, convert them locally, work with the AI you choose, and keep every answer and change connected to its source.
ChatMD Studio works with ordinary files on your PC. Start with the editor, then add conversion, AI, connected knowledge and local history only when they help.
Move from a file to an answer without losing where either came from.
Open Markdown, text, tables, PDF, Word, Excel, PowerPoint, OpenDocument, Rich Text and EPUB from one private workspace.
Convert one file, a mixed queue or a whole folder locally. Before anything runs, ChatMD Studio explains what that route can preserve and what it cannot.
The in-app Teach workflow guides you through Add → Review → Teach, turning useful material into connected knowledge without silently feeding every file to AI.
Choose how much freedom the AI gets: stay grounded in your files, combine file context with broader reasoning, or chat without limiting every answer to the vault.
Brain is the visual map of your connected knowledge base. It shows notes, tags and real links as they exist, so you can discover context without AI inventing relationships.
Changes and Vault Health make local history readable, surface stale or unresolved work, and help recover earlier versions.
Ask, Teach and AI-written change review work with Claude Code, Codex, Antigravity, Ollama or another compatible command-line assistant installed on your PC.
ChatMD Studio does not include an AI account or resell model access. Your provider's plan, usage limits, privacy terms and possible charges still apply.
Open, edit, read or convert each format through its safest supported path.
Choose a file family to see what ChatMD Studio can open, edit, convert and use with Ask. The details change because every format has different strengths—and different limits.
From modern and legacy Word files to OpenDocument, Rich Text and everyday notes.
