Final Round AI
A small team or competent developer can implement the core mock-interview and live-suggestion loop using off-the-shelf ASR and LLM APIs, but reproducing the production-grade stealth desktop client, broad platform compatibility, and the company's large user experience/analytics would be harder and require more engineering and testing.

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 Final Round AI alternatives, with the arithmetic →
What a replacement has to do
- Listen to microphone audio, transcribe in realtime, send context+transcript to an LLM to generate an answer suggestion, surface that answer to the user (stealth UI overlay or earpiece), and save interview transcript + feedback for post‑interview analysis.
What it still won’t have
- Polished, cross-platform desktop app and stealth integration across many interview platforms
- Large user base and community-tested prompts/UX
- Proprietary telemetry and aggregated interview analytics at scale
- Commercial polish, reliability, and product support
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal AI Interview Copilot as a cross-platform Electron desktop app + Node backend that: 1) captures system microphone audio and streams it to a transcription service (use OpenAI Whisper or Google Speech-to-Text); 2) maintains a small local profile (resume + target role) and merges that context with the latest 30 seconds of transcript to build prompts; 3) calls a hosted LLM (configurable OpenAI/other API) to generate a short structured answer (max 60 words) and confidence score; 4) presents the suggestion via a configurable stealth output (hotkey-driven translucent overlay, local TTS to user headphones, or local notification) and logs the transcript+responses to SQLite; 5) includes a mock-interview mode that drives Q&A from a question bank and produces a post-interview feedback report (speech clarity, filler words, structure tips); Out of scope: building a custom LLM, proprietary large-scale analytics backend, paid billing, or multi-user sync. Include error handling for network/ASR/LLM failures, unit tests for prompt assembly and transcript storage, and end-to-end smoke tests for the audio→LLM→output flow.

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.
