Two Mac apps, four web apps and one Instagram bot. All free, each explained in one sentence.
Mycelium is for macOS 11 or later and asks for Full Disk Access so it can read Messages.
Mac apps download as a small zip. The Trail and The Org System are demos filled with sample data. Peppermint and Magic Tree are the full apps, in your browser. InfathomReel works by Instagram message.
What it does: reads your texts and email on your Mac, spots things like “dinner Friday at 7” or “pay by Monday”, and lists them as dates. You approve each one before it goes on your calendar.
Asks for Full Disk Access so it can read Messages. It works on your Mac, with no server that can read your data.
What it does: puts a small strip on the side of your screen. A ring shows how much of your Claude plan you’ve used, and a click lists every Claude Code session that’s running. Add-ons bring search, screenshots and a meeting recorder.
For people who use Claude. It reads your plan usage from the Claude desktop app on your Mac.
What it does: each project is a stop on a trail. Open one and drag its notes from Basecamp to Summit as the work gets done. It’s a to-do list that feels like a walk instead of a spreadsheet.
What it does: splits a club’s members into balanced teams, gives them homework with real due dates, and keeps a Team Cup that only counts work handed in on time. The demo is a made-up club of 100.
What it does: fifty icebreakers ranked by how they really went in meetings. Pick five and it gives you the steps, a timer and how to set up the room, so you can just run the meeting.
What it does: a 3D tree stands on a scannable QR code. Tap it and the leaves fly down into the code. Type your own link and it becomes a QR code for that link, so you can make one for yourself.
What it does: send it a Reel that shows off an app or AI tool. It watches the video, checks the tool it names, and replies whether it’s real or fake, and where to find it.
Needs an Instagram account. The Reel you send goes to InfathomReel’s server so it can watch it and check the tool.
Mycelium and Lichen now ship with their extras switched off. You get the core app first. If you want more, flip an add-on on and it gets its own tab or button. Flip it off and it’s gone, but whatever it saved is kept for next time.
Mycelium and Lichen aren’t from the App Store, so macOS asks you to confirm the first time you open one. It does that for every app from outside the store, and you only do it once. Mycelium needs one more permission; Lichen doesn’t.
Press Download. Your Mac saves a .zip to Downloads; double-click
it and the app appears next to it.
Open a Finder window and drag the app into Applications, so it stays put and updates cleanly.
macOS says it can’t check the app. Go to System Settings › Privacy & Security, scroll down and press Open Anyway. After that it opens normally.
So Mycelium can read Messages: System Settings › Privacy & Security › Full Disk Access, then turn on Mycelium. Lichen doesn’t need this.
The short version of how these apps treat you and your data. The FAQ below goes app by app.
No trial, no subscription, no “pro” version waiting behind a paywall.
Mycelium and Lichen read and store your data locally, with no server that can read it. The few optional parts that go online are listed below.
Mycelium never adds to your calendar or submits anything until you approve it.
None of these apps has its own account to make. InfathomReel needs an Instagram account, since you use it by message.
Apple asks developers to pay for a certificate that skips this warning. These apps don’t have one yet, so macOS asks you to confirm once. Pressing Open Anyway in Privacy & Security is all it takes.
It depends on the app:
An extra feature that comes inside the app but starts switched off. In Mycelium it’s a new tab, like Acorn for scholarships. In Lichen it’s a new button, like chat search. Turn on only the ones you’ll use.
No. It reads the Messages database already on your Mac, which is why it asks for Full Disk Access, and the results stay there. Mycelium’s privacy page lists everything that can leave your Mac, including phone access, which is off until you turn it on.
Yes. Lichen shows usage for a Claude plan and the Claude Code sessions on your Mac, so it’s for people who use Claude. Lichen is an independent app and isn’t made by or affiliated with Anthropic.
Mycelium checks for a new version and offers it to you. For Lichen, download it again from this page when a new version comes out.
Macs with Apple silicon (M1 or newer). Mycelium needs macOS 11 Big Sur or later, and Lichen needs macOS 14 Sonoma or later. The web apps run in any modern browser, on a phone too.
