Description
I wanted to better markdown editor for collaborating with Claude/Codex and built Flashtype (https://github.com/opral/flashtype):- opens local markdown files- Claude/Codex natively integrated (with my existing subscription!)- in-line diffing to quickly accept/reject changes- WYSIWYG (!)The in-line diffs are a big step up to other apps static previews, and, in theory, just the first collaborative primitive.But, I am getting feedback that "editing" might become a thing of the past. Why do I need to see diffs from Codex/Claude if the models are getting so good to the point that they need no correction?Which makes me wonder, how did your writing setup with AI change over the past months? Are you still iterating on posts or are agents one shotting them?

Could you build this?
Yes Flashtype is an Electron or web-based WYSIWYG markdown editor (using TipTap or ProseMirror) that invokes LLM APIs (Anthropic/OpenAI) and displays standard visual text diffs, which can readily be vibe-coded.
