I have tried every note-taking app. Notion, OneNote, Google Docs, and the notes app on my phone. They all work, and they all lose my notes in different ways. Notion buries them under three layers of navigation. OneNote syncs weird across devices. Google Docs is great until I need it offline. And every single one of them needs an account, an internet connection, or both.
So this tool is the boring version. You type notes, they stay in your browser, and you export them when you want a real file. No account, no sync, no cloud, no forgetting where you saved it. Everything runs in your tab and nothing gets uploaded.
Write notes in Markdown, preview them as you go, and export as Markdown, text, or PDF. No account, no upload — your notes stay in your browser.
What this does
This is a plain text editor with one trick: it writes Markdown. You type normally, use a few symbols for formatting, and the preview shows the result. Headings, bold, italic, lists, links, and code blocks all work.
When you are done, you can export your notes as a Markdown file, as plain text, or as a PDF you can print. The Markdown file opens in any text editor, in Obsidian, in Notion if you ever want to move your notes there, or in GitHub if you are keeping a public record.
How to take notes that actually help
The tool is the easy part. The hard part is what you write and how you write it. Here is what I have found works, and what does not.
Write questions, not headings. “Chapter 4” is a heading. “What does the professor say about the Hardy-Weinberg assumptions?” is a question. The question makes you think when you review. The heading just reminds you that the chapter exists.
Leave gaps. If your notes are a perfect transcript of the lecture, you are a tape recorder. Leave blanks where you zoned out, where you knew you would remember, or where the professor said “obvious” and moved on. Those gaps are where the learning happens when you fill them in later.
Use your own words. Copying the slide verbatim feels productive and is not. If you can rephrase the point in your own sentence, you understand it. If you cannot, that is the signal to go back to the reading.
Mark what matters. Highlight the things the professor emphasized, the things on the practice problems, and the things you do not understand. A page where everything is highlighted is a page where nothing is.
Markdown basics
Markdown is a way to format text using plain characters. Here is what you need:
- Headings: Start a line with # for a big heading, ## for a smaller one, ### for smaller still.
- Bold: Wrap text in double asterisks, like **this**.
- Italic: Wrap text in single asterisks, like *this*.
- Lists: Start a line with a dash or a number.
- Links: Put the text in square brackets and the URL in parentheses, like [Google](https://google.com).
- Code: Wrap text in backticks, like `this`.
That is most of what you need for lecture notes. The full Markdown syntax is bigger, but these six cover ninety percent of what students actually write.
How to review your notes
Taking notes is half the job. The other half is going back over them. Here is a routine that works:
- Same day: Fill in the gaps while the lecture is still fresh. Five minutes is enough.
- One week later: Read through and summarize in one sentence per section. If you cannot summarize a section, you did not understand it.
- Before the exam: Only review your summaries and the things you marked as important. Do not re-read every page.
The flashcard tool pairs well with this. When you review your notes, turn key terms into flashcards. Then the Pomodoro timer keeps your review sessions on track.
Frequently asked questions
Does this save my notes?
Not automatically. Your notes stay in your browser tab. If you close the tab, they are gone. This is by design — the tool does not store anything. If you want to keep your notes, export them as Markdown or text. The file is yours.
Can I use this offline?
Yes. The tool runs entirely in your browser. Once the page loads, you do not need an internet connection. This is the advantage over Notion, OneNote, and Google Docs.
How do I export as PDF?
Click the export button and choose PDF. Your browser opens the print dialog, where you can save as PDF. This works in Chrome, Firefox, Safari, and Edge. The formatting is preserved — headings, bold, lists, and code blocks all look right.
Is this a replacement for Notion or OneNote?
No. It is a replacement for the moments when you need to take notes and do not want to fight an app. If you need folders, tags, collaboration, and cloud sync, use Notion. If you need a quick place to write that works offline, use this.
Can I import notes from Notion or OneNote?
Yes. Copy your notes from Notion or OneNote and paste them here. Basic formatting is preserved. Then edit in Markdown and export.
