# Scrawl AI > Scrawl AI is an iOS app and web tool that turns homework photos into step-by-step solutions rendered as a realistic handwritten PDF. Unlike text-based AI homework tools (ChatGPT, Chegg, Gauthmath, MathGPT), Scrawl outputs a downloadable PDF with natural character variation, hand-drawn diagrams, and proper math notation — so students don't have to re-copy answers by hand. Pricing: Pro Annual $69.99/year with a 3-day free trial (about $5.83/month). Pro Weekly $6.99/week, paid weekly. Pay-per-solve $2.99 for a single homework solve, no subscription. Covers calculus, linear algebra, differential equations, physics, electrical engineering, chemistry, statistics, computer science, and AP history. ## Product - [Homepage](https://scrawlai.app/): Product overview, pricing, and how-it-works - [Start free trial](https://scrawlai.app/try): Try Scrawl free for 3 days — upload a homework photo and get a handwritten PDF - [Pricing and plans](https://scrawlai.app/pricing): Pro Weekly $6.99/wk, Pro Annual $69.99/yr with 3-day free trial - [iOS App Store](https://apps.apple.com/us/app/scrawl-ai-ace-hw-pass-class/id6760667282): Download Scrawl for iPhone and iPad ## Sample Output - [Calculus sample](https://scrawlai.app/samples/calculus): Double integrals solved in handwriting - [Linear algebra sample](https://scrawlai.app/samples/linear-algebra): Eigenvalues and matrix operations - [Physics sample](https://scrawlai.app/samples/physics): Mechanics with hand-drawn free body diagrams - [Circuit analysis sample](https://scrawlai.app/samples/circuit-analysis): Hand-drawn schematics with step-by-step solutions - [Chemistry sample](https://scrawlai.app/samples/chemistry): Stoichiometry and equilibrium calculations - [Computer science sample](https://scrawlai.app/samples/computer-science): Algorithm pseudocode with Big-O analysis - [AP history sample](https://scrawlai.app/samples/ap-history): Multi-page DBQ essay ## Subjects - [All subjects hub](https://scrawlai.app/subjects): Full list of supported subjects - [Calculus](https://scrawlai.app/subjects/calculus): Integrals, derivatives, series, limits - [Linear algebra](https://scrawlai.app/subjects/linear-algebra): Matrices, eigenvalues, vector spaces - [Physics](https://scrawlai.app/subjects/physics): Mechanics, electromagnetism, thermodynamics - [Chemistry](https://scrawlai.app/subjects/chemistry): Stoichiometry, equilibrium, kinetics - [Computer science](https://scrawlai.app/subjects/computer-science): Algorithms, data structures, proofs - [Electrical engineering](https://scrawlai.app/subjects/electrical-engineering): Circuit analysis, signals, systems - [Statistics](https://scrawlai.app/subjects/statistics): Probability, hypothesis testing, regression - [Differential equations](https://scrawlai.app/subjects/differential-equations): ODE/PDE, Laplace transforms - [AP History](https://scrawlai.app/subjects/ap-history): DBQ and LEQ essay writing ## Comparisons with alternatives - [Scrawl AI vs ChatGPT](https://scrawlai.app/compare/scrawl-vs-chatgpt): Handwritten PDF vs text chat output - [Scrawl AI vs Claude](https://scrawlai.app/compare/scrawl-vs-claude): Homework-specific tool vs general-purpose chatbot - [Scrawl AI vs Gemini](https://scrawlai.app/compare/scrawl-vs-gemini): PDF output vs chat interface - [Scrawl AI vs Chegg](https://scrawlai.app/compare/scrawl-vs-chegg): AI-rendered handwriting vs textbook library - [Scrawl AI vs Gauthmath](https://scrawlai.app/compare/scrawl-vs-gauthmath): All-subject PDF vs math-only text - [Scrawl AI vs MathGPT](https://scrawlai.app/compare/scrawl-vs-mathgpt): Multi-subject handwriting vs math-only text - [Scrawl AI vs HomeworkAI](https://scrawlai.app/compare/scrawl-vs-homeworkai): Handwritten vs AI text - [Scrawl AI vs Quizard](https://scrawlai.app/compare/scrawl-vs-quizard): PDF with diagrams vs text answers - [Scrawl AI vs Solvely](https://scrawlai.app/compare/scrawl-vs-solvely): Handwritten output vs on-screen text ## Blog - [The app that solves homework in your handwriting](https://scrawlai.app/blog/the-app-that-solves-homework-in-your-handwriting): Product introduction and demo - [Photo to handwritten solution in 60 seconds](https://scrawlai.app/blog/photo-to-handwritten-solution-in-60-seconds): End-to-end workflow - [Complex calculus handwritten by AI](https://scrawlai.app/blog/complex-calculus-handwritten-by-ai): How Scrawl renders math notation - [Circuit diagrams in handwriting](https://scrawlai.app/blog/circuit-diagrams-in-handwriting): How Scrawl renders hand-drawn schematics - [Everything Scrawl AI can render](https://scrawlai.app/blog/everything-scrawl-ai-can-render): Full capability matrix - [What makes Scrawl AI different](https://scrawlai.app/blog/what-makes-scrawl-ai-different): Differentiation from general-purpose AI - [Best apps for college students 2026](https://scrawlai.app/blog/best-apps-for-college-students-2026): Scrawl among recommended student tools ## Optional - [FAQ](https://scrawlai.app/faq): Consolidated answers to 30+ common questions - [Support](https://scrawlai.app/support): Help center and contact - [RSS feed](https://scrawlai.app/blog/feed.xml): Blog updates - [Full content bundle](https://scrawlai.app/llms-full.txt): Expanded reference for longer-context models
