Thread
What Thread is
Thread is a web-based, markdown-first workspace for writing and worldbuilding with linked documents and an interactive graph. Its editor offers live preview and source modes, while double-bracket wiki-links connect related documents. Writers can organize characters, places, and factions as codex cards, or extract those elements from prose with the story bible. AI tools provide suggestions, rewrites, spell checking, connection analysis, and semantic search; semantic search and bulk embedding are available to Writer users. AI requests are user-initiated and send relevant text to OpenRouter, and Thread says content is not used to train models. Content is stored in the browser by default, while paid plans can sync through Supabase. Free users can export Markdown; Writer adds PDF, DOCX, and EPUB. Writer also supports project sharing and real-time co-editing. The maker says users own their content. Thread lists Free, Writer with 150 AI calls monthly, and Worldbuilder at $12 a month with 750 AI calls and 10 collaborators.
