About

Scrawl AI is a homework solving application built for students who need to submit handwritten assignments. Users photograph their homework with their phone, the AI solves each problem step by step, and the solution is rendered as a handwritten PDF that looks authentically written by hand.                                                                                                                          
                 
 Unlike text-based AI tools such as ChatGPT or Gemini, Scrawl AI handles the full workflow from input to submittable output. The rendering engine applies natural variation to every character, including rotation, spacing, and baseline drift, so each page appears genuinely handwritten. Users can draw their own custom handwriting font or choose from preset styles.                                        
                                                                                                                                           
 The application is the only tool on the market that renders hand-drawn graphs, circuit diagrams, plots, and matrices directly into the handwritten output. This is accomplished through a custom glyph compositing pipeline built on LaTeX and TikZ.

 Scrawl AI offers a free tier with three solves and watermarked output. Pro Weekly is $6.99 and Pro Annual is $69.99 with a seven-day free trial. Pro plans unlock unlimited solves, custom handwriting, no watermarks, and up to 20 pages per submission.                            
                                                                                                                                           
 The application was built by a Johns Hopkins University computer science student as a solo project. The core innovation is the rendering engine, which transforms AI-generated LaTeX into authentic-looking handwritten PDFs with natural variation and integrated diagram support.
