Locally in your browser via Chrome's storage API. Nothing is sent to any server. There are no accounts to create.
The extension collects no personal data. Optional anonymous error reporting is available (off by default) and can be enabled in Settings. Error reports contain no conversation content, no email addresses, and no personally identifiable information.
Email collection for product updates happens only via this website, never in the extension.
We do not store or process subscriber data. Email updates are handled via Buttondown. Buttondown Privacy Policy

Yes. Seritor is built on the Manifest V3 framework, ensuring compliance with current Chrome Web Store security and performance standards.
No. The email signup is completely optional and does not affect your access to any Seritor features.
Seritor is built and maintained by Quite Good, a solo developer studio. There is no corporate parent, no venture funding, and no incentive to sell your data.
Your first 10 bookmarks are free. The extension is fully functional during that time. You can purchase at any point.
Core features are a one-time $29 purchase, permanently. A future subscription tier is planned for team features like cross-device sync and sharing. Bookmarking, exporting, labels, search, keyboard shortcuts, and the Library will always be included in the one-time purchase.
The launch price of $29 will increase when v0.2.0 ships with additional capabilities. If you purchase at the current price, you keep that price permanently - including access to the new v0.2.0 features.
Refunds are available within 14 days of purchase. Email billing@seritor.app and we'll process a refund. Please include a brief description of the issue so we can improve the product.
Claude (claude.ai), ChatGPT (chatgpt.com), Gemini (gemini.google.com), and Grok (grok.com). All four platforms are supported from v1.0.
Click the small flag icon that appears on any message in a conversation. The flag turns green to confirm the bookmark. Click again to remove it.
Keyboard shortcut: Cmd+Shift+B (Mac) or Ctrl+Shift+B (Windows) to bookmark the nearest message.
When you bookmark a message, Seritor automatically captures the adjacent prompt or reply. Bookmark an assistant response and the user prompt that triggered it is saved alongside it. Bookmark a user message and the assistant's reply is captured. You always get the full exchange, not a fragment.
A dedicated store for refined, reusable content. When you have a prompt, code snippet, equation, or configuration block that went through many iterations in a conversation, save just the final version to your Library.
Click + on any bookmark to open the Library editor. Edit the content down to just the reusable part, give it a title, and save. Library items are separate from your bookmarks — the original bookmark is preserved.
In the Library view, click any item to copy it to your clipboard. Click the arrow to navigate back to the source conversation.
Minimal. Seritor adds a small flag icon to each message in a conversation. The flags are subtle and semi-transparent until you hover. They don't interfere with the platform's own interface or move any existing elements.
The popup (accessed via the toolbar icon) is a self-contained panel. It doesn't inject anything into the page beyond the bookmark flags.
Yes. Seritor adjusts automatically, no need for manual switching.
Yes. Open the Seritor popup, go to Settings, and toggle "Show flags" off. All flag UI disappears immediately — your bookmarks are preserved. Toggle it back on when your task is complete.
Markdown (.md), HTML (.html), JSON (.json), and PDF (via print dialog).
Markdown works in Obsidian, Notion, VS Code, and any text editor. HTML produces a styled, self-contained document. JSON is designed for developer tooling — scripts, databases, and data pipelines. PDF opens a print-ready page in a new tab.
Four ways, depending on what you need:
Single bookmark — click the MD button next to any bookmark.
By conversation — click the ⬇ arrow on any conversation group header and choose a format.
All bookmarks — click the ⬇ arrow in the main header.
Custom selection — use Select mode to pick specific bookmarks, then export.
Exports preserve code blocks with proper syntax fencing, headings, lists, and formatting. You can include or exclude AI thinking data via the "Include AI reasoning" toggle in Settings.
By default, Seritor strips thinking summaries from Claude and Grok when capturing bookmarks. Exports contain only the actual response.
If you want to include thinking data - for example, to understand how the AI reasoned through a problem - enable "Include AI reasoning" in the Settings panel. The change applies to future bookmarks immediately.
No. Unpinning hides the toolbar icon but the extension remains installed. All bookmarks, Library items, and settings are preserved. Click the puzzle piece icon to repin it.
Uninstalling the extension permanently deletes all local data. There is no cloud backup or recovery in v1.0.
Cmd+Shift+B — toggle bookmark on the nearest message
Cmd+Shift+↑ — jump to previous bookmark
Cmd+Shift+↓ — jump to next bookmark
On Windows, replace Cmd with Ctrl. Shortcuts work on all four platforms while you're in a conversation.
Click the tag icon on any bookmark to add a label. Labels are freeform text - use whatever fits your workflow. Labels autocomplete based on your existing labels. Filter by label using the chips below the search bar. Apply labels in bulk using Select mode.
Yes. The search bar searches across bookmark content, context (the paired prompt or reply), and notes. Combined with label filtering and the platform filter, you can find any bookmarked message in seconds.
Age indicators. A hollow dot (◦) means the bookmark is over 30 days old. A filled dot (●) means over 90 days. Hover for the exact age. They're a reminder to review older bookmarks and decide whether they're still useful.
These platforms hide message timestamps inside menus or don't expose them to extensions at all. Exports show the date you bookmarked the message instead. Claude is the only platform that makes timestamps accessible — Claude exports show both the original message date and the bookmark date.
Each Chrome profile has its own independent set of bookmarks. There is no sync between profiles in v1.0. Cross-device and cross-profile sync is planned for a future update.
Yes. Exports preserve code blocks with proper syntax fencing, inline code, headings, lists, bold, and italic formatting. This is handled by Turndown, a dedicated HTML-to-Markdown converter — not by text extraction.
Very little. Seritor's content script is lightweight - it adds flag icons to messages and listens for clicks. There's no continuous processing, no background polling of conversation content, and no network requests (unless you've opted into error reporting).
The extension has been tested on conversations with 800+ messages and 100+ bookmarks without noticeable performance impact.
Seritor only activates on the four supported platforms (Claude, ChatGPT, Gemini, Grok). It doesn't run on any other websites.
If you want to temporarily disable it entirely, right-click the Seritor icon in your toolbar and select "Manage extension", then toggle it off. Your bookmarks and settings are preserved.
This appears when Seritor couldn't read the conversation title at the time of bookmarking - usually because the page hadn't fully loaded yet. Navigate to that conversation and Seritor will update the title automatically on the next visit.
AI platforms update their HTML structure regularly. Seritor uses defensive selectors with fallbacks and each platform's logic is isolated — a change to one doesn't affect the others. If a platform update breaks bookmark detection, a fix is pushed as quickly as possible.
Earlier versions stored message content as plain text. The current version converts HTML to properly formatted Markdown with code blocks, headings, and lists preserved. Older bookmarks retain their original format. To get the improved formatting, remove the old bookmark and re-bookmark the same message.
Email support@seritor.app with a description of the issue. If you've enabled anonymous error reporting in Settings, we may already have diagnostic data. We aim to respond within 48 hours.
