tesseraOrganizes itself
Every bookmark gets subject tags, a summary and a suggested collection — without you filling anything in.
every link, a piece of the mosaic
Bookmarks you find again by meaning
Describe what you need — “that cheese bread recipe” — and Tessera finds it, even with other words or in another language. While you browse, it shows on its own the bookmarks related to the open page.

See Tessera in action
Recorded with the real extension: the AI model, the pages and the results are real.
When you click, the video loads from YouTube in privacy-enhanced mode. Nothing is sent before that. Watch on YouTube
Your library working while you browse
The AI model runs in your browser and understands what each page is about. Here is how that shows up day to day.
Related to the open page
Open the side panel on any site and see, without typing anything, your bookmarks about the same subject. Switch tabs and the list follows.
- Reading a service's docs, the guides and alternatives you had already saved show up.
- The open page is read only to compare — nothing is sent.
Search the way you remember
“How to publish a site without a server”, “short home workout”. Results come by meaning, with the matching excerpt highlighted — even when the page uses other words or another language.
- Popup with Alt+Shift+F, address bar with sf + space, side panel and Library.
- Filters by tag, collection, site, date and topic.
Topics that emerge from your bookmarks
No predefined category list: Tessera groups bookmarks by what they have in common, and names come from the members themselves.
- Create your own topics — they keep their name when everything is recalculated.
- “Looks like” suggests where to place what has no topic; “Similar” shows what to add.
- Open all bookmarks of a topic in tabs, in one click.
Answers based on your bookmarks
Optional, with your own key for an AI service (Anthropic, OpenAI, DeepSeek, Ollama or compatible). The answer comes with [1] citations that open the bookmark used — and, without enough basis, it says so.
- You allow each purpose and see where data goes and what is sent.
- Monthly spending limit; revoke at any time.
Your way
Three appearances — Calm (space and reading), Dense (many bookmarks per screen) and Visual (tiles in the topic color) — in light, dark or following the system. English and Portuguese.
And everything a good library needs
Brings the bookmarks you already have
Import your Chrome or Edge bookmarks in one click. The browser's original tree is never modified.
Suggestions (optional)
A discreet “+” tells you when a page you keep visiting deserves to be saved. Only counters, without the address.
History in search (optional)
Pages visited in the last 90 days show up marked in search, with “Save” in one click. Turning it off deletes everything.
Broken links and trash
Check your bookmarks and see why each one failed. 30-day trash; export and import everything as JSON.
Shortcuts
Alt+Shift+S saves the page, Alt+Shift+F opens search and sf in the address bar searches right away.
Get started in three steps
No sign-up. The guide shows every screen in detail.
- Install and pin the iconFrom the Chrome Web Store or Edge Add-ons.
- Let the model download onceAbout 200 MB, on first launch. After that it runs on your computer.
- Import your bookmarksLibrary → Import. Within minutes, search by meaning works.
Real privacy
There is no Tessera server. Your data doesn't go through us because there is no “us” in the way.
Stays on your computer
- Your bookmarks, page text and organization.
- The AI model, which runs in the browser.
- Your AI service key, if you use one.
- No account, no ads, no analytics, no telemetry.
Leaves only when you ask
- The pages you saved, to read their content.
- The AI model, downloaded once.
- Link checks, when you ask.
- The AI service you configured, only for the purposes you allowed. Banking and health sites are never sent.
Frequently asked questions
Is Tessera free?
Yes. No paid plan, no ads and no account. If you use an AI service with your own key, that service bills you, and Tessera helps you control it with a monthly limit.
Which browsers does it work on?
Google Chrome and Microsoft Edge on desktop (Windows, macOS and Linux).
Do I need a graphics card?
No. With a compatible card, Tessera uses a larger, more accurate model (EmbeddingGemma); without one, it uses a smaller model that runs on the processor.
Does it work offline?
Once the model is downloaded, searching and organizing work offline. The connection is only used to read new pages, check links and — if you turn it on — the AI service.
Do my browser bookmarks change?
No. Tessera only reads the bookmark tree to import and follow new ones. It is never modified.
Do I need an AI key?
No. Search by meaning, related bookmarks and organization work with local AI. A key is only for richer tags and answers with citations.
How do I get help or suggest something?
Open an issue at github.com/casheiro/tessera/issues. Don't include personal data or your API key.
