Write math and chemistry on a tablet or e-ink reader: an ink page for the pen, fractions, roots, Greek and scripts in a short notation, H2O and SO4^2- typed like a chat. Copy LaTeX or MathML, save PNG. Free, local, no account.
Formulapad typesets what you write. It does not solve, check or grade anything, and it does not recognise handwriting: ink stays ink.
Formulapad is a notepad for anyone who writes math or chemistry with a pen on a tablet or e-ink reader. A sheet is an ink page plus notation lines: type (a+b)/(c+d), x^2 or sqrt{x} in a math line, H2O or 2H2 + O2 -> 2H2O in a chem line, and it is typeset right below. Ink stays ink; nothing reads your writing.
Copy any line as LaTeX, MathML or text, or save ink and formulas as a PNG. No account; sheets stay in this browser and are never sent to a server.
Example: type a reaction from chemistry homework, copy the LaTeX and paste it into your report.
