Keep the Thread

Save pages with why they mattered, keep threads of thought, and get your week on the internet — all on your device.

Bookmarks keep links. Keep the Thread keeps why. Save any page with one click — the extension keeps a readable copy, a screenshot, and your answer to the question that matters: what caught your attention? Threads of thought. Related saves and thoughts live together in a thread that reads like a conversation: sources, notes, open questions, conclusions. Paste a link straight into a thread. Mark questions answered as your thinking lands. Copy a whole thread as clean Markdown to share it. Your week on the internet. Every Friday, a notification: your week is ready. Saves grouped by thread, what you concluded, and the questions still open. Copy it or email it to yourself. AI that stays yours. Instant summaries are built in, and search understands meaning, not just words — a small AI runs entirely on your own computer, so your reading is never uploaded to be indexed. Every thread can brief you: where you left off, what your sources say, your open questions, and what to read next. AI text is always labeled and kept next to its sources. Bring your own AI, if you want. Connect your own Claude or OpenAI key and summaries get deeper and briefs can research the live web — requests go directly from your browser to the provider you chose, under your key, never through any server of ours. Off unless you set it up; one switch turns it back off. Or hand a thread to Claude, ChatGPT, or Perplexity in a tab — pre-filled, sent only when you choose. Private by architecture. No account. No server. No analytics. Your library lives in your browser, exportable as a single file whenever you want it.
