Meet Tummel

The study companion that remembers every mistake you make — and makes sure you never make it twice.

Free to start · No card needed · Cancel anytime

Most AI tutors answer once and forget you. Tummel never does.

Tummel remembers every mistake, rebuilds your weak spots, and shows its work — all grounded in your own materials.

Ask anything — get the worked solution

Other tutors hand you an answer and hope you trust it. Tummel shows every step and checks the math against an independent calculator — so you actually learn the method. Try it right here, no account needed.

x e^x

Product rule:

\tfrac{d}{dx}\left(x e^x\right) = (1)\cdot e^x + x\,e^x

Group the terms →

e^x + x\,e^x

Factor out

e^x

→ $e^x(1 + x)$
