SymboliX

SymboliX — the symbolic calculator that explains itself

Type a problem and get an exact symbolic answer, typeset like a textbook. Every result is a card: differentiate it, integrate it, plot it, or open the step-by-step solution with one tap.

COMPUTE
• Derivatives, indefinite and definite integrals, limits, series
• Equations and systems, with numeric roots when there is no closed form
• Simplify, expand, factor (and prime-factorize integers)
• Matrices: determinant, inverse, eigenvalues
• Differential equations (desolve)

SEE IT
• Results that are functions plot themselves: definite integrals show their area, solved equations mark their roots
• Full-screen graphing with pan, pinch-to-zoom and live updates as you type

PROGRAM
• An Xcas-style language: functions, local variables, for / while / repeat loops, recursion, lists, print output
• Example programs: Fibonacci, primes, Newton's method, the Collatz sequence, matrices
• Variables carry across cards; reset them any time

STEPS AND THE AI TUTOR
• Step-by-step solutions are free for everyone
• Want to know why each step works? Unlock the AI tutor once: it explains the reasoning, the common traps and how to check the answer (100 walkthroughs a month; a one-time purchase, not a subscription)

ALSO
• Notebooks to keep your work
• Computing, plotting and programming work offline and are free forever
• English and Simplified Chinese
