Show HN: Flashtype – Markdown editor for Claude and Codex with in-line diffs
Flashtype is an open-source markdown editor that integrates natively with Claude and Codex, offering WYSIWYG editing and in-line diffs for accepting or rejecting AI-generated changes. The developer questions whether traditional editing will become obsolete as AI models improve, and invites discussion on how writing workflows with AI have evolved.
Background
Flashtype is an open-source markdown editor designed for working with AI coding/writing assistants, specifically Claude (Anthropic's AI model) and Codex (likely OpenAI's coding AI). It lets users open local .md files, chat with the AI inside the editor, and see proposed changes highlighted as in-line diffs (like GitHub's red/green change tracking), which can be accepted or rejected one by one. The creator posted this on "Show HN" (Hacker News' section for showing off personal projects) and is asking a broader question: as AI models improve, will human "editing" of AI output become obsolete, or will we still need to iterate on drafts? The post reflects a current debate among tech writers and developers about whether AI is nearing "one-shot" quality or if human review still adds real value.
