Pros and cons
- Very fast photo-to-steps workflow
- Broad subject coverage beyond maths
- No ads, even on the free plan
- Option to reach human tutors
- Answer-first design makes copying easy
- Weaker on advanced calculus and proofs, with occasional silent errors
- Frequent complaints about billing and cancellation; ByteDance ownership raises privacy questions
How it scores
Popular and broad, but it leads with answers and slips on harder maths; billing complaints lower value.
