STFU
A single competent developer can build and maintain a useful replacement (OCR + LLM + simple UI) in about a week; nothing on the site indicates durable technical moats that block a DIY rebuild.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All STFU alternatives, with the arithmetic →
What a replacement has to do
- User uploads a chat screenshot -> app extracts conversation context -> LLM proposes 3–4 reply options in selectable tones -> user copies or shares chosen reply.
What it still won’t have
- Mobile-store presence and native app polish (iOS/Android)
- Existing userbase and App Store/Play reviews
- Any proprietary model tuning or internal datasets the vendor may use
- Polished UX, analytics, and A/B testing infrastructure
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
STFU does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal web-first replacement for Yazcam using React for frontend, Node.js + Express for a small backend, Postgres (or SQLite) for lightweight logging, Tesseract (or a cloud OCR API) for screenshot text extraction, and OpenAI/Anthropic API for LLM replies. In scope: screenshot upload and resizing, OCR to extract chat text, speaker/role parsing, prompt templates that generate 3–4 reply variants and a compatibility score, a UI showing tone options (e.g., Casual, Bold, Polite, Playful), copy/share buttons, server-side API key proxying, basic usage logging, and unit/integration tests for OCR -> parse -> LLM pipeline. Out of scope: native iOS/Android apps, App-Store submission, advanced analytics, and multi-user billing. Include error handling for failed OCR and LLM responses, retry/backoff for API calls, rate-limit protections, and automated tests for core flows.

- 3 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score90
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
