Collect from Chrome and Edge
Choose an image, text selection or page element, preview it, and save it to your inbox, a collection or an editable canvas.
Connect your extension
Download the extension ZIP from the private Gitea release, extract it, then open chrome://extensions or edge://extensions. Enable Developer mode and choose Load unpacked for the folder containing manifest.json.
In Rail Cove, open Settings → API keys. Create a dedicated key with library:write. Add boards:write to save into canvases and shared-space canvases you can edit.
Open the extension, enter your Rail Cove API origin, and connect using the key. Grant access only to the chosen API host. A remote installation must use HTTPS; loopback HTTP is for local development.
Save something worth keeping
Open a normal web page. Choose the extension's capture action or a context-menu action for selected text, a link or an image.
For an element capture, activate the picker, choose the visible element, and review its plain text or selected image. Form fields and password contents are excluded.
Review the title, source link, selected content and destination. Add an optional note, then save. Shared-space destinations are canvases you have permission to edit.
After the save confirmation, open the selected inbox, collection or canvas in Rail Cove. A draft kept on this browser remains local until you choose Save.
If smart tagging is enabled for the Rail Cove account, the newly saved item can queue automatic tagging after capture. Successful tags appear in the Rail Cove item reader, where you can edit or remove them immediately.
Privacy and retries
- Capture starts after your action; the extension does not crawl or monitor your browsing in the background. API keys stay in trusted extension storage and are never given to page scripts.
- Image captures keep the selected external image URL and its source page. The source site can change or remove that image. Use an authorized file upload in Rail Cove when you need a durable local copy.
- If a save response is lost, retry the unchanged draft. The server returns the existing saved item for the same draft ID. Changing an already submitted draft requires a new save request.
- The extension sends only the content you selected to the Rail Cove capture endpoint. Smart tagging is a later server-side operation on that one saved item; it does not give page scripts a provider key or cause the extension to scan other tabs.
Troubleshooting
- If a page blocks extension access, use Copy link or paste the selected text into Rail Cove. Browser settings, store pages and other protected browser pages cannot be picked.
- If a destination is missing, check that the key has boards:write and your account has editor access. Verify your email before using shared membership.
- If the key expires or is revoked, reconnect with a new dedicated key. Revoking a key in Settings stops access immediately; disconnect the extension when you finish using it.
