Extension Metadata

About this extension
Postory turns what you view into a private, searchable archive that stays on your device.

On X, the public posts that enter your viewport are recorded as you scroll. Open a ChatGPT conversation and Postory archives a local snapshot of it. Then find anything again through the Browsing History entry inside X, the platform switch in the archive, or the extension's fallback page.

Features in 0.0.5:
- Records public X posts that enter the active viewport, including fast scrolling
- Archives complete ChatGPT conversation snapshots (messages, roles, times)
- Preserves first viewed, last viewed, and repeat-view count
- Searches text, display names, and handles locally; filters by date and platform
- Incrementally identifies your own posts encountered while browsing
- Deletes individual records or clears the local archive
- Exports portable JSON, CSV, and Markdown files
- Embedded X-native history surface with same-tab permalink navigation
- Paid plans sync entitlements across up to 5 devices per account
- Supports English and Simplified Chinese

Postory stores history locally. It does not capture direct messages, passwords, or authentication cookies, and it never uploads archived content. A three-day trial begins at the first successful capture. Trial expiry stops new capture but never blocks viewing, deletion, or export of existing local data. Subscriptions are managed on https://postory.cc through Stripe; the extension only reads your Postory account's subscription state from api.postory.cc.

Postory is not affiliated with or endorsed by X or OpenAI.
