> Thoth is a private browser memory extension for Chrome, Brave and Firefox. Remember what you read, organize saved pages, and find them again with keyword or optional search by meaning. # Thoth: Private browser memory extension You forgot the title. You forgot the site. You remember it was about walking into a room and forgetting why. That’s enough for Thoth, a private memory for everything you read in your browser. Launching October 2026 for Chrome, Brave and Firefox · Launch news only, [never shared](https://thothmemory.com/privacy). ## Find a page from what you remember You read hundreds of pages. Within days their titles and addresses fade, while what they were about stays with you. Thoth can find a page from that memory, such as “forgot why I walked into a room”. ## Less searching. More finding. History needs the address. Bookmarks need you to have saved it. Thoth only needs whatever stuck with you. “That article about walking into a room and forgetting why.” [Save this comparison as an image](https://thothmemory.com/assets/thoth-compare.png) Searching for “forgot why I walked into a room”: browser history finds no results, because the page is titled “Why Walking through a Doorway Makes You Forget | Scientific American”. Bookmarks find nothing, because the page was never saved. Thoth finds it from what you remember. ## Keep reading. Thoth remembers. Follow your curiosity. Thoth remembers along the way, so you can return to the ideas that matter. ### Read it now. Find it later. The pages you spend time reading are remembered on their own. No saving, no tagging, no deciding what might matter later. No extra habit to build. Just read as you always do. ### Keep the line that made you pause. Highlight a passage and add a thought. Come back to your words and the original page together, right where you left them. ### Remember the idea. Find the page. Describe what stuck with you, without guessing the title or the exact words.

[Get in touch](https://thothmemory.com/support). - ### Do I need an account to get started? No. Install Thoth and it starts remembering what you read, without signing up. You need an account only to buy a plan: Lifetime, or Pro and Max for search by meaning and encrypted backup. - ### What leaves my device? Nothing during ordinary use without an account, and Lifetime sends none of your memories anywhere. If you turn on search by meaning, page titles, limited portions of text and your search terms go to an online service. Page addresses are never sent. Encrypted sync uploads an archive only you can unlock. - ### How is this different from Chrome’s AI history search? Chrome’s AI history search lets you find visited pages using everyday language. Thoth builds an archive from pages you actively read, with collections, notes and saved passages you can search and export. It works in Chrome, Brave and Firefox, and capture and keyword search stay on your device without an account. - ### What’s the difference between Lifetime and Pro? Lifetime is one payment for Thoth on your own devices: unlimited memories and private keyword search in every browser you use, and your reading never leaves your device. You sign in to a Thoth account to buy it, and signing in unlocks it in each browser you use; it then keeps working offline. It has no search by meaning, backup or sync. Pro is a subscription that adds search by meaning, plus encrypted backup and sync on 1 browser installation (Max: 3), which run on our servers. - ### What happens to my memories if I stop paying? They stay yours. Your archive lives in your browser, so cancelling never deletes it. You keep everything you saved and can keep searching it by keyword; search by meaning, backup and sync stop, and on Free new pages are saved only while you have fewer than 1,000 memories. Your encrypted backups stay stored, and restoring them needs Pro or Max again. Lifetime never expires. ## Read something good. Find it again. Let Thoth remember it, so you don’t have to.
