Your personal knowledge library.

Get better at knowledge management, learn effectively, and improve retention.


Writing good notes takes some experience. Strive to be concise. Put down only the most essential points. Use your own words. Remember, you will re-read it later — be your own ideal writer.


Keep it clear — it's better to have many small paragraphs. Break text into sections, use bullet points, and ordered lists. Markdown is great for that!


Building a knowledge library is much easier with tags. Any word prepended with `#` becomes a tag. Filter notes by tag from the sidebar. Or use full-text search.


Cross-links let you connect notes. Linking one note to something you already know makes it much easier to remember. Connected notes can be viewed with "Quick Preview".


Space-repetition is a proven way to improve retention. It's being used in software like Anki and SuperMemo. Rekowl takes care of what and when you need to review.

How to learn efficiently?

Oh, it's a fascinating topic. I have recently written an article on learning and knowledge management, have a look!

Why rich editor?

Rekowl editor is loosely based on markdown. That allows our users to structure information better than with the plain text. Elements like headers, bulleted lists, citations, and others are good for comprehension.

How reviewing works?

We believe in repetition. Every time you re-read your note, you get a chance to better understand, and to improve retention in your head. Thus reviewing your notes allows for better comprehension and remembering.

How do I tag my note?

Just add a word starting with # anywhere in your note. If you're familiar with Twitter, you should understand the concept. All your tags are always there on the left sidebar, you can use them to categorize notes.

That's why we came up with reviewing system. Every note go through 7 levels. Every time you review a note, it updates to the next level. Each level require more time till note is reviewable. So the first time you review your not in 1 week, and the last time in 6 month.

Can I export my data?

Yes. You can download your data at any moment. After all, your notes are just markdown files. To do this, go to Settings / Export.

Can I remove my account?

Yes. Go to Settings / Delete Account. Note that will completely remove all your data, so don't forget to export your notes first.
