Saving to your formula sheet
Your formula sheet is a personal library of equations you want to remember. Pull things out of any solve, tag them, and revisit them later — perfect for exam prep.
Save a formula
In any solution, hover over an equation. A small + button appears. Click it and the formula is added to your sheet. You'll be asked for:
- A short name (defaults to something readable, like "Quadratic formula")
- An optional tag — for example
calculus,mechanics, ormidterm-3 - An optional note in your own words
Saved formulas show up at /formulas and persist across devices the moment you sign in.
Organize with tags
You can tag a formula with multiple labels. The sidebar of /formulas lists every tag you've used; click one to filter. There are no folders — tags are flat, lightweight, and you can add or remove them any time.
A few patterns that work well:
- By topic —
algebra,trig,linear-algebra - By course —
mat101,phy220 - By urgency —
exam-soon,daily-practice
Search and quick-paste
Anywhere in the app, hit Cmd/Ctrl + K to open the command palette and start typing a formula name. Hit Enter to paste the LaTeX directly into the editor. That's the fastest way to bring a saved formula into a new solve.
Edit, duplicate, delete
Each formula has its own page with the rendered equation, the LaTeX source, and your note. From there you can edit any field, duplicate the formula (useful for storing variants like "with friction" and "without friction"), or delete it.
Export your sheet
On every tier you can export the full sheet to PDF or LaTeX — handy for an end-of-semester cheat sheet (if your instructor allows it!). The export inherits the same options described in Exporting to PDF.
Formulas don't count toward your storage quota. Save as many as you like.
