Copperplate Coach

Master Copperplate capitals: trace A–Z, optional AI tips & practice feedback. No ads, no accounts.

Copperplate Coach helps you study traditional English Copperplate capitals (round hand / Engrosser’s style): curated lessons for every letter, on-screen tracing over licensed exemplar artwork, and optional AI coaching for deeper tips and photo feedback on your practice sheets.

Key Features • Browse capitals A–Z with overviews, stroke ideas, and common pitfalls
• Trace each letter on your iPhone or iPad with finger or Apple Pencil (PencilKit) over a semi-transparent guide
• AI letter coach — expand any lesson with structured tips and a short practice drill (optional)
• AI practice coach — photograph your paper practice; get strengths, improvements, and a suggested drill
• No accounts, no ads, no in-app purchases — lesson text and exemplar images are bundled in the app

How It Works

1. Open Letters and tap a capital.
2. Read the lesson, study the exemplar, then tap Trace over this letter to practice on screen.
3. Optionally tap AI: deeper tips for extended guidance (sends text to our AI provider; see Privacy Policy).
4. Use the Coach tab to pick or snap a photo of your practice and tap Get AI feedback.

Educational Use Only
AI output is for learning calligraphy. Do not use it to forge signatures or official documents.

Privacy & Data • No personal data collection — we do not ask for your name, email, or an account. On-screen tracing stays on your device and is not uploaded.
• Bundled exemplars — capital reference images are from Wikimedia Commons (Copperplate letter Version2 set), © Thirunavukkarasye-Raveendran, CC BY-SA 4.0. Attribution is shown in the app and in our privacy policy.
• AI processing — when you request letter tips or practice feedback, data is sent over HTTPS to Replicate (replicate.com), which runs Google Gemini. We do not operate our own backend for the app. Text-only AI requests may include a minimal placeholder image due to API shape; only the Coach tab sends your practice photo.
• Camera & Photos — camera only when you tap Camera on the Coach tab; library read only when you choose a photo there.
• No tracking — no analytics SDKs, ad networks, or cross-app tracking.
