Notoo

A family of browser tools that do their work on your machine. Files, tokens and notes stay in the tab — no upload step, no account, no watermark.

01

Why it exists

Almost every tool that touches your files asks you to upload them first. A PDF you want to split, a screenshot you want a background removed from, an API token you want to test a request with — all of it goes to somebody's server, and you take it on faith that it leaves again. Notoo inverts that: the work happens in the browser, on your machine, and the file never leaves it. That is the through-line across all of these, not a feature of any one of them.

02

How it is shaped

Each app is its own subdomain and each tool inside it is its own URL, so anything you use often is a bookmark rather than a menu you navigate. Once a page has loaded it does not need the network again. There is no signup wall, no file-size cap and nothing stamped on the way out. Where syncing genuinely helps — the editor and the journal, which you might want on two machines — it exists, and it is opt-in.

Notoo Editoreditor.notoo.app
Notes, code, docs and sketches in one file tree — the extension picks the surface.
  • Full Monaco engine for code, with autocomplete and multi-cursor
  • Markdown and rich-text docs, Mermaid diagrams, slash commands
  • A .draw freehand canvas for wireframes and diagrams
  • A REST client in .http files — your tokens stay in the browser

  • Optional cloud sync — sign in and pick it up on another device
02
Notoo Toolstools.notoo.app
29 PDF and image tools that never see your files. Each is its own bookmarkable page.
  • 21 PDF tools — merge, split, compress, convert, protect, edit
  • 8 image tools, including background removal that runs on-device
  • No file-size caps, no daily limits, no watermark on the way out
  • Every tool is a URL — pin it, share it; once loaded it needs no network
03
Tuckittuckit.notoo.app
A timer and Pomodoro you pull out of the edge of any page. A Chrome extension — free, no account.
  • A 44×6px tab on one edge — that's the whole resting footprint
  • Pull the rope out and it knots at 5 / 10 / 25 / 50 / 90, each labelled with the clock time it lands on
  • Pomodoro beads the rope instead: pull three beads, get three cycles, and it runs unattended
  • Block the sites you name for the length of every work bead, and open them again on the break
  • Float it above Figma, Slack or a terminal in a real always-on-top window
04
Notoo Journaljournal.notoo.app
Write in short bursts that thread like a conversation, with a planner and a timer attached.
  • Threaded entries with tags, moods, images and pinning
  • Todos with due dates and repeats you can write against
  • A pop-out Pomodoro that survives reloads and logs each session
  • Streaks, a writing heatmap, word goals and a mood trend
  • ⌘K search across every thread, plus Markdown export
  • Optional cloud sync — sign in and pick it up on another device
05
Bookmarklybookmarkly.notoo.appIn beta
A bookmark manager that assumes the web rots — so it keeps the page, not just the address.
