Togya is a private studio notebook for makers. Record how you make things — crochet, knitting, sewing, woodwork, painting, cooking or any craft — and turn your process into a clear tutorial when you are ready. PRIVATE BY DEFAULT • Every work starts private. Saving, marking it done or getting AI suggestions never publishes it. • You choose exactly what becomes public: title, introduction, process photos. • Revision history: every edit is kept; restoring creates a new private draft. RECORD YOUR PROCESS • Add process photos from the camera or library, notes and steps at your own pace. There is no minimum photo count. • Declare where materials come from (your own work or an authorized source). ORGANIZE WITH AI (OPTIONAL) • With your explicit consent, AI turns your private process into a step-by-step tutorial proposal. • You review every suggestion. Facts you confirm as the author are locked against AI rewriting. • Each organization uses 1 monthly AI credit; recovering a past result is free. PRIVATE BOOKS • Collect your works into a private book with chapters. Editing is free and never changes your original works. DISCOVER • Browse public works and tutorials by category, with long lists that load as you scroll. • Scan a Togya QR code to open a public work, profile or bounty. BOUNTIES AND INVITATIONS • Ask the community a question and reward the best answer with To points. • Invite friends; rewards are granted after their first real work. Available in 17 languages. Sign in with Apple, Google or email.

Verdict
The clearest difference is in-app purchases: Togya at none against Prime Rush's 1. Togya also leads on ads (none vs shown) and update cadence (every 3 days vs every 3 weeks). On price there is nothing between them.
