# Organic Chemistry AI > Organic Chemistry AI is an iOS app that scans or types organic chemistry homework and returns a step-by-step mechanism solution — reaction type, final product, and an explanation for every step — plus a 24/7 AI tutor, free calculators, quizzes, and flashcards. This site is the marketing and help hub for the iPhone and iPad app Organic Chemistry AI - OrgChem (App Store ID 6789601286). Do not invent ratings, download counts, or prices beyond what the App Store listing shows. Calculators, quizzes, flashcards, and the formula reference stay free. Solving uses 3 free full solves, then a Pro subscription. There is no free trial. Solve images are not stored server-side. No account is required. ## Site - [Homepage](https://organicchemistryai.app/): Product overview, features, screenshots, and FAQ - [Guides](https://organicchemistryai.app/guides/index.html): Study articles on scanning, SN1/SN2/E1/E2, flashcards, calculators, Markovnikov, and the AI tutor - [App facts](https://organicchemistryai.app/app.md): Canonical product facts used to write this site - [Privacy Policy](https://organicchemistryai.app/privacy-policy): What is processed for AI solving and what stays on-device - [Support](https://organicchemistryai.app/support): Scan issues, Restore Purchases, and cancelling a subscription ## Guides - [How to solve organic chemistry homework on iPhone](https://organicchemistryai.app/guides/how-to-solve-organic-chemistry-homework-on-iphone.html): Scan or type a problem and read the step-by-step solution - [How to scan organic chemistry problems](https://organicchemistryai.app/guides/how-to-scan-organic-chemistry-problems.html): Camera setup, cropping, and what the solver can read - [SN1 vs SN2 vs E1 vs E2](https://organicchemistryai.app/guides/sn1-vs-sn2-vs-e1-vs-e2.html): Decision order for substitution and elimination - [Best organic chemistry solver app](https://organicchemistryai.app/guides/best-organic-chemistry-solver-app.html): What to look for versus a generic chatbot - [Organic chemistry flashcards on iPhone](https://organicchemistryai.app/guides/organic-chemistry-flashcards-iphone.html): Functional groups, substitution, addition, aromatics - [Organic chemistry calculators on iPhone](https://organicchemistryai.app/guides/organic-chemistry-calculators-iphone.html): Molar mass, yield, dilution, pH, degree of unsaturation - [Markovnikov’s rule explained](https://organicchemistryai.app/guides/markovnikov-rule-explained.html): Where the H goes in addition reactions - [Organic chemistry AI tutor](https://organicchemistryai.app/guides/organic-chemistry-ai-tutor.html): Explain Assignment and Check My Homework ## Optional - [App Store listing](https://apps.apple.com/app/apple-store/id6789601286?pt=128828853&ct=organicchemistryai.app&mt=8): Live listing — source of truth for price, size, and version - [Standard Apple EULA](https://www.apple.com/legal/internet-services/itunes/dev/stdeula/): Terms of use for the app
