What Trezio is

Trezio is a bookmark manager and personal knowledge library. You can save:

  • links (web bookmarks), with their title, description and image
  • text notes
  • screenshots and other images
  • voice notes, which can be transcribed into searchable text

It is for people who save a lot from the web and want to find it again later: links, notes and ideas kept in one calm library instead of scattered across browser bookmarks, chats and note apps.

How saving works

A link is saved the moment you press save. Its title, description and thumbnail are filled in afterwards, in the background, so saving never makes you wait.

AI summaries and tag suggestions are generated only when you ask for them, from an item's edit view, on every plan. Nothing is sent to an AI model automatically when you save.

How search works

Search reads the full text of your notes and voice-note transcripts, plus titles, descriptions, AI summaries, links and tags. Semantic search also finds saves that mean what you typed, even without the same words. It doesn't search inside the web pages you save.

Organization

  • Nested folders, as deep as you like, with custom icons
  • Charms: Trezio's tags, added by you or suggested by AI on request
  • Smart filters
  • Favorites
  • Trash, with restore
  • Card, list and masonry views
  • ShareSpace: share a folder as a public, read-only page that visitors can copy into their own Trezio

Security and privacy

  • Logins in the vault are encrypted on your device with AES-256-GCM before they reach Trezio's servers. Trezio stores only ciphertext.
  • The encryption key is derived from your master password with PBKDF2-SHA256 and 600,000 iterations. The master password never leaves your device.
  • Row-level security on every table: the database scopes each request to your account, so one user's data can't reach another's.
  • Auto-lock: the master password is held only in memory while you work and cleared after inactivity, 30 minutes by default.
  • Your content is never sold, used for advertising or used to train AI models.

The details are on the security page.

Your data

  • Import (free on every plan): HTML bookmark files from Chrome, Edge, Firefox and Safari; HTML or CSV exports from Raindrop.io; Pocket's export (the CSV inside its zip, or its older HTML file); Instapaper's HTML export; and Trezio's own JSON backup. Folders carry over and tags become charms.
  • Export (Pro): HTML, the standard Netscape bookmark file every browser and bookmark manager imports; CSV; and a full JSON backup with notes, tags and folders. Vault credentials are never included in any export.
  • Delete: deleting your account removes your account and all its data permanently, and cancels any active subscription.

Platforms

  • Web app, in any modern browser
  • Browser extension for Chrome and Edge
  • Android app

There is no iOS app and no desktop app. On an iPhone, Trezio works in Safari.

FAQ

Questions about Trezio

Is Trezio free?

Yes. The free plan holds 100 items in up to 5 folders, with 1 secure vault and 3 voice-note transcriptions, and includes AI summaries, every view mode and the browser extension. Pro removes the limits and adds export and Google Drive sync for $3.70 a month, or $2.95 a month billed yearly ($35.40 a year).

Is my data encrypted?

Logins you keep in the vault are encrypted on your device with AES-256-GCM, using a key derived from your master password with PBKDF2-SHA256 and 600,000 iterations. The master password never leaves your device, so Trezio stores only ciphertext. Row-level security keeps every save private to your account.

Can I export everything?

On Pro you can export your library as HTML (the standard Netscape bookmark file every browser and bookmark manager imports), CSV, or a full JSON backup with notes, tags and folders. Vault credentials are never included in an export. Import is free on every plan.

Does Trezio have semantic search?

Yes. Alongside search over titles, descriptions, AI summaries, links, tags and the full text of your notes and voice-note transcripts, semantic search finds saves that mean what you typed, even without the same words. It does not search inside the web pages you save.

Is there an iOS app?

No. There is no iOS app and no desktop app. Trezio runs in any browser, including Safari on iPhone, and has a Chrome/Edge extension and an Android app.

Is Trezio the same as trezio.io?

No. Trezio is the product at trezio.app, made by silicode (silicode.co). It is not affiliated with trezio.io or trezio.tech.
