Thought Cloud

Private semantic memory for your browsing — free, and runs entirely on your device.

Thought Cloud helps you find useful pages again—even when you cannot remember the exact title or wording. It saves each page's title, URL, and main visible text to your browser, creates embeddings with a bundled on-device model, and lets you search that private memory by meaning. Key features: • Search previously visited pages using natural language • Capture clean article, discussion, YouTube title and description, ChatGPT, and Reddit content • Avoid repeated copies through URL and exact-content deduplication • Keep page content, embeddings, and searches in local browser storage • Delete the complete local memory at any time from the popup • No account, analytics, advertising, tracking, or external server Thought Cloud requests site access so it can read each page's title, URL, and main visible text for the feature described above. That information is processed and stored only on your device. YouTube transcripts are not captured in this version.
