Welcome to the first major update to Lemma! We’ve been hard at work making your AI tutor even smarter and easier to use.
• Photo Mode is Here: Sometimes a problem is too complex for standard text scanning. You can now toggle to "Photo Mode" to snap high-quality pictures of complicated equations, graphs, and diagrams.
• Smarter Camera Physics: We completely re-engineered our image processing engine. No matter how you hold your device, Lemma now perfectly aligns your photos behind the scenes so the AI always sees exactly what you see.
• Under-the-Hood Polish: Various bug fixes and performance improvements to make your tutoring sessions faster and more reliable.
Happy learning! If you're enjoying Lemma, please consider leaving a quick review - it helps us out a lot.
