Besides the Mac apps, we keep a handful of small tools at tools.noteifyapp.com. They are free, they run in your browser, and you do not need an account. The ones that work with your files read them right in the browser tab, so nothing is uploaded.
Remove EXIF and GPS data from photos
A photo file can hold more than the image: where and when it was taken, and the phone or camera model. The EXIF remover shows the metadata in each photo and lets you download a copy with it removed. Drop up to 50 photos at once and get them back as a ZIP. It is worth a minute before you post photos, list something on a marketplace or send pictures to someone you do not know.
Cornell notes template
The Cornell notes template lets you fill in cues, notes and a summary in the browser, then download a blank PDF or one with your notes filled in, a page for GoodNotes, or a file for Obsidian or Notion. If the method is new to you, start with how to take Cornell notes.
AI Skill Scanner
If you use Claude Code, Codex, Cursor or another coding agent, its skills are text files with instructions the agent follows. The scanner reads a ZIP of your skills or a single SKILL.md and points to the lines that look like hidden instructions, scripts that download and run code, or attempts to read your secrets. This experimental check flags lines worth a second look; a clean result does not guarantee that a skill is safe.
Goldratt's dice game
This is the matchstick-and-dice game from The Goal, turned into a simulation. Each station rolls a die and passes matchsticks down the line, and you watch work pile up in front of the slowest one. Five scenarios walk through the five focusing steps, and a 500-game comparison shows how each change affects output in the simulation. Once the page is open, it keeps working without the internet.
Tree Outliner in the browser
The web version of Tree Outliner lets you write an outline and see it as a list, a tree or a mind map. The browser version works with one document. If you want more, Tree Outliner for Mac is the full app, and this page explains how the browser version works.
Free Mac apps, too
Some of our Mac apps are free as well. You can find them on our free Mac apps page.
The tools are also listed on one page here: free browser tools.
