FROM FILES TO USEFUL KNOWLEDGE
A focused workflow for real knowledge work.
Start with the files you already own — an Obsidian vault opens as it is. ChatMD Studio helps you make them useful without moving them into somebody else's cloud.

YOUR ASSISTANT, CONNECTED TO YOUR KNOWLEDGE
A brain your AI can actually use.

Add pasted text, documents or articles only after review.
Open the citation and read the note it came from.
Brain maps real notes, tags and links locally.
