By the SelGPT team. Updated October 1, 2026. Source: https://selgpt.app/ai-for-math

Type a problem or upload a photo of it. SelGPT works through it step by step, explains each step, and checks your own working if you share it.

> SelGPT solves maths problems step by step and explains each step. Sel-Rigel, its reasoning model, is built for multi-step problems in algebra, calculus, statistics and logic, and is included in SelGPT Plus, about 950 messages a month. Sel-Vega can also read a photo of a problem, so you don’t have to type it.

## What it can help with

- Algebra, calculus, probability and statistics problems.
- Word problems, turned into equations you can follow.
- Proofs and logic puzzles, reasoned step by step.
- Checking your working and pointing to the first mistake.
- Reading a photo or screenshot of a problem (with Sel-Vega).
