Common Questions
Where is my data stored?
Locally in your browser via Chrome's storage API. Nothing is sent to any server. There are no accounts to create.
What happens if a platform changes its website?
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.
Will features I paid for move behind a subscription?
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.
Does it work with code-heavy conversations?
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.
How do refunds work?
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.
