Fullary — AI Chat Memory & Workspace

Turn selected messages on ChatGPT into an encrypted local library you can search, organize, revisit, export, and share.

Fullary keeps useful ChatGPT messages close to the work that produced them. Bookmark one user or ChatGPT message—or a selected passage—then search and organize it in an in-page library without scrolling through a long chat. LOCAL-FIRST BY DEFAULT Fullary stays off unless you select Enable Fullary on ChatGPT after reading its in-product disclosure. Before that choice, it does not scan visible message structure, read message text, decrypt the saved library, or enable message actions. When you save, Fullary stores only the chosen text and the source details needed to organize it and return to its conversation. The library is encrypted at rest with AES-256-GCM in the current Chrome profile. A non-exportable device key is stored separately in the extension's IndexedDB origin. Ordinary saves, folders, searches, source URLs, locators, and exports are not sent to Fullary. The local library works without an account. It does not automatically sync or back up, and all ChatGPT accounts used in the same Chrome profile share that library. Export JSON before removing the extension or clearing browser data if you need a backup. Incognito use is disabled. EXPLICIT ONE-MESSAGE LINKS Creating a public link is separate from local saving. Select the chain icon, review the complete plain-text message, choose an expiry, and select Create link. Fullary then opens its exact confirmation page, visibly identifies the signed-in Fullary account that will own the link, and requires a final explicit confirmation. If the creator is signed out, the same short-lived draft resumes after sign-in. The only ChatGPT-derived content transferred is the exact reviewed plain-text message and its user or assistant role. The extension also transfers the chosen expiry preset and bounded security metadata: confirmation time, ten-minute draft expiration, and high-entropy draft nonce, idempotency, and share-token values. After website sign-in, Fullary derives a one-way opaque binding from the authenticated Fullary account to detect an account switch; the extension does not read that account from ChatGPT or the local vault. These fields bind the explicit confirmation, prevent replay, enforce expiry, and create and manage the resulting link. The public snapshot excludes the private ChatGPT source URL, chat or project title, folder, locators, account details, surrounding conversation, local vault, attachment content, and attachment metadata. The draft is retrievable for up to ten minutes. After the confirmation page retrieves it, the message text is replaced immediately by a text-free receipt. Expired entries cannot be published and are removed on the next extension event or browser restart. Anyone with the resulting /s/ link can open it in any browser without an account until it expires or is revoked. They can forward or screenshot it, and link previews may show an excerpt. Free creators can choose 1 hour, 1 day, or 1 week, with 1 week as the default and maximum. Existing Pro and Owner accounts can also choose 1 year or Permanent until revoked. The extension contains no checkout or upgrade link; subscriptions are separately purchased and managed on Fullary.com. FEATURES - Bookmark individual user or ChatGPT messages with one inline icon. - Save a selected passage or choose a local folder from Fullary's context menu. - Search saved text, chat titles, source roles, and folders inside ChatGPT. - Reopen the original conversation and attempt to highlight the saved source. - Copy a private source locator that contains no message text and grants no conversation access. - Review and create an anyone-with-link copy of exactly one chosen message. - Optionally hand off to ChatGPT's own Share control for content ChatGPT itself supports; Fullary does not inspect or transfer files through its link flow. - Export the local library as JSON. - Review or reset Fullary's message-access permission at any time. Fullary works on chatgpt.com in supported desktop versions of Chrome. Exact source recovery is best-effort because ChatGPT does not provide extensions a guaranteed per-message permalink and may change its page structure.
