ChatTube (formerly ChatTube AI) vs Mathos AI (formerly MathGPTPro)

ChatTube lets you chat with YouTube videos through a Chrome extension or web app. Paste a link, ask questions, and get answers grounded in the video transcript, with summaries, translations, and timestamped references back to specific moments.

The product uses ChatGPT to analyze video content and supports videos without native captions by transcribing audio. Free users get 3 videos per day; paid plans raise daily credits and extend transcription limits up to 4 hours per video on Pro.

ChatTube also transcribes podcasts and points users to SpotScribe for Spotify. The stored domain chattubeai.com now hosts unrelated gambling content; the active product lives at chattube.io.

Mathos AI is an education math solver and tutor that turns a photo, typed equation, or word problem into step-by-step solutions, quizzes, flashcards, and animated lesson videos. One prompt can branch into a worked answer, a 5 to 10 second video first frame, practice cards, and an adaptive review path when you miss a concept.

Generic chatbots hand back a final number with little scaffolding. Mathos breaks problems to their core, repairs the prerequisite you missed before repeating the topic, and the AI Tutor watches your whiteboard steps to catch errors at the exact line where reasoning breaks. The company reports 5 million students and 100 million problems solved.

High school and college students use it for calculus, algebra, and physics homework, while parents get session summaries through a dashboard. The product is free to start with a 3-day trial on paid plans, and an enterprise video API tier offers 3,800 generated minutes per month.
