SketchAI - Turn articles & audio into hand-drawn visual notes

SketchAI converts articles, URLs, and audio into hand-drawn visual notes using AI. Unlike ChatGPT image generation, SketchAI pre-processes text first to eliminate garbled characters and ensure accurate output. Choose from 10+ styles including Chinese brush, student notes, bento grid, and cartoon. No monthly subscription — buy credits and pay per use.
