The best free AI tutor in 2026: free tiers compared

The most generous free AI tutors are ChatGPT study mode and Gemini Guided Learning: both are included on free accounts for ages 13 and up, and both guide with questions instead of just answering. Khan Academy's exercises and videos are free, but its Khanmigo tutor isn't free for families. Ask Poppy's free tier is 30 messages a day of voice or text tutoring on Apple devices, and Photomath's free tier shows basic step-by-step maths solutions.
