What is Gauth?
Gauth started in 2020 as Gauthmath, a photo math solver, and has grown into a general homework helper that also covers sciences and writing, with an option to route hard questions to human experts.
Parents should weigh two things: it hands over full solutions instantly, and it is owned by ByteDance, the company behind TikTok, which matters to families and schools that care about where student data goes.
Does Gauth give students the answers?
Yes. Gauth returns step-by-step answers in seconds across math, science and writing. That makes it effective for checking and very easy to copy from.
Key features
- Photo scanning across many subjects
- Step-by-step solutions and AI chat follow-ups
