FermemoActually remember everything you write down
Fermemo brings your notes back just as you're about to forget them. With a few minutes of review a day, knowledge moves from short-term to long-term memory.
You write, Fermemo remembers the rest
The scientifically proven method of spaced repetition gives you the most lasting learning for the least effort.
Take notes
Write notes with rich text, images, video and files. On your phone, share a web page or text straight to Fermemo.
Review at the right time
Turn on "Remember" and Fermemo brings the note back on the very day you'd forget it, and sends you a notification.
Learn for good
The more you remember, the longer the intervals: 1 day, 6 days, 2 weeks, 1 month… Knowledge sticks with just a few reviews.
Beat the forgetting curve
Most newly learned information is forgotten within a few days. Every well-timed review lifts the curve again and slows forgetting.
Everything you need to learn, in one place
Notebook, review cards, study assistant and habit tracker in one.
Smart review
The SM-2 algorithm learns how hard each note is and adjusts the review interval to you. With browser and phone notifications, you never miss a review.
Study with AI
Generate quiz questions from any note in one click, have your open-ended answers graded, or memorize a text step by step.
Search by meaning
It finds things even if you don't remember the exact words. Ask your notes a question and get an answer that cites its sources.
Locked notes
Sensitive notes are encrypted on your device. No one can see the content, not even the server.
Routines
Track your habits and see your streaks and statistics.
Workspaces
Work, school, personal… Each workspace has its own category tree. A fitting category is suggested as you write.
On every device
Install it on your phone like an app; it works offline and stays in sync everywhere.
Easy to move
Import your notes in bulk from a JSON file. Export all your notes whenever you like.
Let your notes be your AI assistant's memory
Connect Fermemo to Claude or ChatGPT. As you chat, the assistant searches your notes, reads them and adds new notes for you.
- Say "summarize my Docker notes" and the assistant finds the relevant notes
- Have a summary of the chat saved straight to the right category
- Have it make a quiz from your notes and find your gaps
- Safe: it can't delete notes or see your locked notes, and you can remove access in one click

What you might be wondering
Is Fermemo really free?
Yes. The Bronze plan is free forever, and no credit card is required. You can use all the core features, including review, search, routines, and connections to Claude and ChatGPT.
What is spaced repetition, and why does it work?
Reviewing something just as you're about to forget it keeps it in your memory much longer. Fermemo automatically works out the next review day for each note based on how easily you remembered it; you just review whatever comes up.
Are my notes safe?
Your notes live only in your account. If you use "locked notes" for sensitive ones, the content is encrypted on your device and can't be read even on the server. You can export all your notes at any time.
Can I use it on my phone?
Yes. Open Fermemo in your phone's browser and use "Add to Home Screen" to install it like an app. It works offline, sends notifications and lets you share content from other apps.
How do I set up the Claude connection?
After creating your account, copy the address from the "AI assistant connections" card on the Settings page; on claude.ai, paste it under Settings → Connectors → Add custom connector and grant access with your Fermemo account. It all takes about a minute.
How do I set up the ChatGPT connection?
In ChatGPT, find Fermemo under Settings → Apps and click Connect; log in with your Fermemo account, choose the access level (read and write, or read only) and allow access. No address to copy.
Can I bring my notes over from other apps?
You can import your notes in bulk from a JSON file, and add text, links and images one by one. Categories that don't exist yet are created automatically.
Remember tomorrow what you learned today
Write your first note and let Fermemo remind you at the right time. No setup, no card.
