WriteX features
Built for long-form writing and local projects—not a cloud notebook or code IDE.
AI writing agent
WriteX Agent drafts and edits across multi-file project context—reads the docs you attach, shows tool steps, keeps manuscripts off WriteX servers, works with BYOK multi-model.
Learn more →Bring your own key (BYOK) & multi-model
WriteX multi-model BYOK: switch DeepSeek, Kimi, Claude, GPT, Qwen, and more in one writing workbench. Keys encrypted on device—no WriteX-hosted models.
Learn more →Context & multi-file attachments
Attach multiple Markdown files and assets from your project as agent context for cross-file writing—control what the AI can read; files stay in your local folder.
Learn more →Local-first & security
WriteX is local-first: folder-as-project Markdown, no document upload to WriteX servers, API keys encrypted on device—built for privacy-conscious writers.
Learn more →WYSIWYG Markdown editor
WriteX offers a local, WYSIWYG Markdown editor that keeps plain .md files in your project folder—ideal for long-form writing without living in raw syntax.
Learn more →Project search
Search Markdown across your WriteX project folder on device—jump to hits in the editor or attach them to the agent. No search upload to WriteX.
Learn more →Version snapshots
WriteX keeps local version snapshots for project docs so you can roll back after agent edits or big restructures—complementary to Git, not a replacement.
Learn more →Web search
When online, the WriteX agent can pull public web pages into answers—local private files stay local unless you attach them to context.
