gengo app 对比 Mathos AI (formerly MathGPTPro)

Gengo 是一款为日语学习者打造的跨平台漫画和轻小说阅读器。你可以上传自己的图片文件，阅读时配备内置的 OCR 词典和词汇工具，让你无需离开页面即可查词。

该应用受到 AJATT 等沉浸式学习方法的启发，弥补了如 Kaku 这类仅支持 Android 的阅读器的不足。你可以提供自己的阅读材料；Gengo 不托管或分发受版权保护的漫画或小说。

它支持 PNG 和 JPG 图像、整个文件夹以及 ZIP 压缩包。网页版应用免费使用，用户还可以通过 Patreon 进行付费支持以帮助开发。

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.
