What it fixes
Stop keeping the tab open because you fear losing the context.
Traditional bookmarks preserve a URL. Source Memory preserves why that visit mattered: what led to it, what it opened, the project and intent, and who was declared to control the browser at the time.
Save an exact visit as a native Chrome bookmark with a subject-first title, tags, project, actor, intent, status, notes, and date.
Preserve opener-tab lineage, same-tab navigation, redirects, supported search context, and later child pages without calling tab activation causation.
See committed visits, detect Threads, build Trails, archive windows, and restore work later.
Assign a browser window to a named agent, then explicitly record the handoff back to the human.
Search by title, page context, tag, project, Thread, actor, domain, status, Trail, date, or ordinary words.
Reopen a page, outbound branch, Trail, or archived window instead of keeping every tab alive.
Provenance discipline
Observed facts stay separate from inference.
Opener-tab and same-tab navigation relationships are kept distinct from ordinary activation order.
ACTIVE_AFTER records sequence without inventing a cause.
Agent Control is a user declaration and handoff record—not cryptographic proof of who moved a mouse or pressed a key.
Privacy boundary
Your provenance ledger stays in your Chrome profile.
Version 1.0.1 has no host permissions, all-sites access, content scripts, account, analytics, advertising, cloud sync, remote code, or network calls from extension code. Selected text is stored only when the user explicitly invokes the selection-saving action.
Consent first
Automatic committed-visit capture begins only after the onboarding disclosure is accepted.
Local controls
Pause recording, exclude domains, set retention, export JSON, delete a day, or delete all Source Memory data.
Honest sync limit
Native bookmarks may follow Chrome Sync when the user enables it; the richer provenance ledger does not sync in this version.
Release status
The product is a verified source candidate—not a Store release.
Version 1.0.1 is merged and packaged for Chrome Web Store review. Exact-package acceptance, publisher upload, Google review, and Store-installed smoke testing remain separate gates. Top AI Tools For does not publish product pricing yet.
