Audio and podcasting decision
Notta
A competent engineer can build a usable transcription+summary workflow in a week and stitch together ASR/LLM APIs, but Notta's certified security posture, native apps, integrations and enterprise operations are expensive to replicate—so keeping the paid service is reasonable for enterprise-grade needs.

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.
What a replacement has to do
- Record or upload audio → transcribe (ASR) → diarize/split speakers → generate AI summary/action-items → allow edit/export/share
What it still won’t have
- ISO27001 / SOC2 level compliance and attested security posture
- Large-scale reliability/operations and enterprise SLAs
- Native mobile apps, Chrome extension and device-specific features (Notta Memo)
- Pre-built calendar/CRM integrations and full product automation workflows
- Brand trust and large installed user base
What remains hard
- Brand trust

Paying is—cheaper in year one.

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 app (React frontend + Node/Express + Postgres) that: 1) accepts audio/video uploads and extracts audio (ffmpeg), 2) sends audio to an ASR API (configurable provider) and stores transcripts with timestamps, 3) performs speaker diarization (use an off-the-shelf library/service) and attaches speaker labels, 4) calls an LLM to produce meeting summaries and action-items, 5) provides a web UI to edit transcripts, view summaries, search transcripts, and export to TXT/DOCX. Out of scope: native mobile apps, Chrome extension, enterprise SSO, compliance attestations. Include error handling, retries for external API calls, basic unit/integration tests, and deployment scripts (Docker + one-click deploy to a single managed VM or container service).
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 5 cited sources+3
- Price verified on pricing page+3
- Hard moats found in the evidence-3
- Evidence score60
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.
