Corollary / Compare / Goodnotes
Corollary vs Goodnotes.
Goodnotes is an all-round digital notebook. Corollary is an iPad app built for people who write mathematics: it turns Apple Pencil handwriting into real, editable LaTeX. Here is where each is better.
Which is better for math?
Choose Goodnotes for an all-round notebook on every platform, with audio recording, PDF annotation and step-by-step solving. Choose Corollary if you write mathematics and want every line in editable LaTeX, a .tex file for Overleaf, and notes that Claude and ChatGPT can read and search.
Side by side
| Corollary | Goodnotes | |
|---|---|---|
| Handwriting to LaTeX | Every line, typeset beside your ink as you write | Select math with the lasso and convert it; you can edit and copy the LaTeX |
| .tex export | Yes | No; exports Goodnotes files, PDF and images |
| Overleaf | Yes | Not documented |
| Search | Handwriting, drawings, typed text and LaTeX | Handwriting, typed text, PDF text and scans |
| Claude and ChatGPT | Read and search the notebooks you choose, and suggest additions you accept | Create new documents only; can't read or edit existing ones |
| Solving math | No | Math Assist and Goodnotes AI (Solve, Teach Me) |
| Audio recording | No | Yes, with Note Replay |
| Platforms | iPad, Mac, iPhone | iPad, iPhone, Mac, Windows, Android, web |
| Price | Free; Pro $9.99 a month or $99.99 a year | Free (3 notebooks); paid plans from $11.99 a year |
Can you edit LaTeX in Goodnotes?
Yes, for the math you convert. In Goodnotes you lasso handwritten math and choose Convert, then edit the LaTeX shown at the bottom of the view and copy or share it. Conversion is per selection, and Goodnotes doesn't export a .tex document. In Corollary every line is typeset automatically, and the whole page is one LaTeX document you can export.
Can Claude or ChatGPT read my Goodnotes notes?
Not through Goodnotes' official integration. Goodnotes says its Claude and ChatGPT integration "creates new documents only. It cannot edit or analyze documents already in your Goodnotes library." Corollary's MCP server works the other way round: the AI reads and searches the notebooks you choose, and anything it writes is a suggestion you accept or remove. How Corollary works with AI.
