 4. **Pick it up again.** Save the review file with its source snapshot and your notes. You can reopen it later, even offline. You can also save and [compare repository search snapshots](#see-how-a-project-changes-over-time).
 
 When you come back to an idea, you can see what you found—and why you made that decision.

-The browser app uses plain HTML, CSS and JavaScript: no build step, model API, database or account setup. Public reads happen only after you search, choose a discussion, check a linked GitHub repository, request an HN parent comment, or request the AgentAtlas snapshot. Search terms go to the selected GitHub or HN Search service; the snapshot request goes to AgentAtlas without search terms. Discussion requests go to GitHub, HN Search or the official HN API. Cookies and authentication are omitted. Reports and notes are not uploaded or saved automatically. Parent comments fetched on demand are shown live and are not added to the saved review; an already-collected parent comes from the original snapshot. The optional multi-issue collector uses Python's standard library.

Public reads happen only after you search, choose a discussion, check a linked GitHub repository, request an HN parent comment, or request the AgentAtlas snapshot. Search terms go to the selected GitHub, Hacker News Search or Stack Exchange API; the snapshot request goes to AgentAtlas without search terms. Selecting a Stack Overflow result requests that question and its answers. The page shows source, author and license links, converts post HTML to plain text, and marks shortened excerpts. Cookies and authentication are omitted. Reports and notes are not uploaded or saved automatically. The Stack Overflow viewer stores hashed request fingerprints and source backoff times in local browser storage to avoid repeating searches too soon. Its downloaded review is a separate format, opened only in the Stack Overflow viewer; older CLI reports are not compatible. Parent comments fetched on demand are shown live and are not added to the saved review; an already-collected parent comes from the original snapshot. The optional multi-issue collector uses Python's standard library.
