ReVoice: AI writing-style app (web/iOS/Android) - Sell Project

ReVoice is a working starter codebase for an AI writing tool. A user pastes 3 or more samples of their writing, the app builds a 10-dimension style profile (tone, vocabulary, rhythm, punctuation and so on), then drafts new posts in that style. History is saved on the device, with optional Supabase accounts. Status, plainly: $0 revenue. No paying customers, no active users. Not published in the App Store or Google Play. Sold as-is. What you get: Web app (plain JavaScript, no framework) that also runs as the iOS and Android app via Capacitor 8 Vercel serverless API: profile, generate, health, plus Stripe checkout and webhook routes Engine that calls Google Gemini, or an optional local LLM (any OpenAI-compatible server such as LM Studio) The same engine in Python, including a grounded mode that drafts only from a supplied source text and checks its supporting quotes word for word Supabase schema with row-level security (optional accounts) 19 passing Node tests (API routes against a fake model, plus an app smoke test) README with setup, configuration and a list of what isn't done Honest limitations: Stripe routes exist and are tested but aren't wired into the app; Supabase is off until you add keys. Voice-matching quality is unproven. In a small blind test (3 writers, same model on both sides), the voice-profile drafts were preferred in 1 of 3 pairs against a plain prompt shown the writer's posts. No custom or fine-tuned model, and no special hosting: it calls the Gemini API. The name isn't a protected brand; plan to rename. No domain, social accounts, customer data or mailing list are included. Delivered as a zip of the source code, with ownership transferred under a short sale agreement. Payment through escrow. Sold as-is, no ongoing support.
