ReadThread
Understand what you read, without leaving the page
ReadThread is a local-first Chrome extension that explains selected webpage or PDF content, reads structured tables and selection-anchored visuals, and creates bounded page overviews. Continue asking questions in the side panel, return to saved reading threads, export the conversation, or hand it off to another chat platform for review.

Built for focused reading
- Explain a highlighted passage using only the context needed to interpret it.
- Get a readable overview of the currently loaded page without automatic scrolling.
- Preserve table headers and values as structured Markdown.
- Add one focused visual for charts, figures, and complex tables when useful.
- Read remote or local PDFs through exact text or bounded visual capture.
- Continue a source-grounded, multi-turn conversation with Markdown and LaTeX.
- Bring your own OpenAI-compatible, Anthropic, Gemini, or Ollama model.
- Keep reading history locally in the browser and delete it at any time.
- Export Markdown, JSON, JSONL, CSV, or PDF.
- Fill a reviewable conversation draft in ChatGPT, Gemini, Claude, DeepSeek, or Qwen without automatically sending it.
ReadThread has no account, advertising, analytics, or ReadThread-operated cloud conversation storage.
