Fullary — Local Chat Memory

Save individual ChatGPT messages in an encrypted local library, organize them, search them, and return to their source.

Fullary keeps useful ChatGPT messages close to the work that produced them. Bookmark one user or ChatGPT message or a selected passage, find it in an in-page Fullary drawer, organize it into local folders, and return to its source conversation with best-effort highlighting. PRIVACY BEFORE ACCESS Fullary stays off unless you select Enable Fullary on ChatGPT in its prominent in-product disclosure. Before that affirmative choice, it does not scan visible message structure, read ChatGPT message text, decrypt the saved library, or enable message actions. After consent, Fullary processes visible message roles and structural locators to place controls and support return-to-source. It does not read message text while adding those controls. Text is read only after you choose an action, such as saving a message or passage, copying its private source link, or opening a saved result that Fullary must match to its source. ENCRYPTED AND LOCAL-ONLY When you save, Fullary stores that chosen text plus its source role, date, folder, ChatGPT title, canonical source URL, and source locators or fingerprint. The entire library is encrypted at rest with AES-256-GCM and a fresh random IV for every write. Its non-exportable device key is stored separately in the extension's IndexedDB origin. Fullary never sends message content, source metadata, searches, folders, or exports to Fullary or any other server. It has no analytics, sync, checkout, payment, or public-sharing path. Public sharing is not included in this store build. OPTIONAL ACCOUNT PAGE Local saving works without an account. After consent, the drawer shows one optional Create free Fullary account / Sign in button. Only a trusted click opens https://fullary.com/extension/welcome in a new tab. The extension sends no saved text, source metadata, search, folder, export, account token, or identifier with that action. It does not read the destination tab or sign the local extension into an account. Ignoring the button changes nothing. Pro features are labelled only as coming soon; this build has no paid CTA or checkout. The local library does not automatically sync or back up. All ChatGPT accounts used in the same Chrome profile share that library, so use separate Chrome profiles when account separation is required. Export JSON before removing the extension or clearing its data if you need a backup. The exported file is plain JSON and must be protected by the user. Incognito use is disabled. 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, source titles, roles, and folders without leaving ChatGPT. - Reopen the original conversation and attempt to highlight the saved source. - Copy a private source link containing a locator, not message text. - Export the local library as JSON. - Review or reset Fullary's message-access permission at any time. - Optionally open Fullary's free-account/sign-in welcome page without sending local-vault data. 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. Version 0.4.0 stores text only; it does not copy images, audio, video, or uploaded-file blobs.
