Google's Nano Banana Pro Presents Handwritten Math Solutions
Google's Nano Banana Pro can read (OCR - Optical Character Recognition) a hand-written math problem, and then present the solution in the same handwriting.
Google’s Nano Banana Pro is by far the best image generation AI out there.

I gave it a picture of a question and it solved it correctly in my actual handwriting.

X's Grok agrees that it is possible, presenting this argument:
Nano Banana Pro integrates with Gemini's multimodal capabilities, allowing it to analyze uploaded images (like a photo of handwritten notes) and interpret the content, including mathematical expressions...Once recognized, Gemini 3 Pro handles the computation...
The model then creates a new image by "in-painting" or extending the original notebook page, rendering the step-by-step solution (substitution, integration, evaluation) in a style that replicates the user's handwriting—sloppy loops, inconsistent spacing, and notebook lines included. This is powered by Nano Banana Pro's advanced style transfer and few-shot prompting, where the input image serves as a reference for consistency.
This goes one almost unimaginable step beyond the transcriber from Isaac Asimov's 1953 novel Second Foundation (the short story ...And Now You Don't appeared in 1949), which also produced excellent handwritten copy:
The machine had been delivered two days ago on her first adult birthday. She had said "But father, everybody - just everybody in the class who has the slightest pretensions to being anybody has one. Nobody but some old drips would use key machines-"But when it was delivered, it was the model she wanted... and copy was turned out in a charming and entirely feminine handwriting...
