How Flashtype works with Claude Code & Codex
The agents live inside the editor, working on your real files - so writing with AI feels like editing a doc, not babysitting a chat window.
Ask Claude Code or Codex
Run either agent in a pane right next to your draft. It reads and edits the same files you're writing in - no copy-paste, no context juggling.
Review every diff
Each change lands as an inline diff in your document. Accept the good edits, reject the rest - nothing changes until you say so, and version control keeps every earlier version restorable.
Better than pasting drafts into a chat window
Most “AI writing” still means shuttling text in and out of a separate chat. Flashtype puts the agents where your files already live — and shows you every change before it lands.

FAQ
Can I use Claude Code inside a markdown editor?
Yes. Flashtype runs Claude Code in a pane right next to your draft, so it reads and edits the same local .md files you're writing in - no terminal switching, no copy-paste.
Does Flashtype work with Codex too?
It does. Both Claude Code and Codex are built in. Point either agent at your folder and it works directly on your real files.
How is this different from pasting into ChatGPT?
A chatbot can't see your files or save changes - you paste in, copy out, and hope nothing got dropped. Flashtype keeps the agents in your editor and shows every edit as an inline diff you accept or reject.
Is Flashtype free and open source?
Yes. Flashtype is free, open source under the MIT license, and runs on macOS. Issues, pull requests, and stars are welcome on GitHub.
