Case study

Novera Recorder

Record a Meet, get a meeting summary structured by business template — all 100% local.

The internal tool that transcribes and summarises my high-stakes conversations — candidate interviews, client briefs, mission debriefs — without any audio or text leaving my machine. Capture from Google Meet via a Chrome extension, local transcription, summary by business template.

The challenge

I run my recruitment business through a stream of high-stakes conversations: candidate interviews, client briefs, mission debriefs. My manual workflow — PC recorder → .wav file → Vosk script → copy-paste into ChatGPT — was slow, fragile (Vosk without punctuation produced poor summaries) and multiplied alt-tabs.

Worse: sensitive conversations — compensation, candidate backgrounds, client contacts — transited through a third-party cloud, with the associated confidentiality risk. Taking notes by hand during an interview cuts listening quality. There was no searchable history, and no standardised output by context.

The solution: an end-to-end cycle

From the Chrome extension to the exported summary, the full cycle runs on my machine alone — without alt-tabbing during the meeting.

Start from Meet

Chrome extension: one click “Start” on Google Meet, auto-titled from the Meet name.

Two-track capture

Mic + WASAPI loopback captured on two separate tracks (Me / Participants).

Live transcript

faster-whisper on snapshots every ~20 s, during the meeting.

Post-processing

On “Stop”: full transcription, then speaker merge (Me / Participants).

Templated summary

Summary via Ollama with a business template: default, candidate-interview, client-brief, mission-debrief.

Usable session

In the app: editable title, full-text search, PDF export.

Privacy by default

No audio or text leaves the machine: no cloud transit, no external logs.

GDPR framing

Standardised consent announcement at the start of each interview.

Under the hood

A Python backend running on CPU only (no GPU required), deliberately frozen: no environment variables, no front-end build step. The whole chain — capture, transcription, summary, storage — lives locally.

Audio capture

Mic + WASAPI loopback via sounddevice, soundfile writes, RMS level computed with numpy. Two separate tracks to distinguish speakers.

Local transcription

faster-whisper 1.2 (medium model, CPU INT8) via ctranslate2. Around 5 seconds of compute for 5 minutes of audio.

Local summarisation

Summary generated by Ollama (qwen2.5:7b model), entirely on the machine, with a business template chosen at the end of the session.

Storage & search

Sessions persisted in SQLite with FTS5 full-text search. PDF export delegated to the browser.

API & extension

FastAPI + Uvicorn backend exposing 16 API routes. A Chrome Manifest V3 extension with a content script injected on meet.google.com.

Zero-dependency frontend

Vanilla HTML/CSS/JS: no framework, no build step, no CDN. Deliberately frozen config, with no environment variables.

My role: design and development, solo

From spotting the need to shipping it, I built Novera Recorder alone: designing the capture cycle, developing the backend and the extension, choosing a 100% local architecture out of a confidentiality requirement. It’s the tool I use for my own interviews.

Design

Capture cycle, business templates, alt-tab-free flow.

Backend development

Audio capture, transcription, summary, FastAPI API, SQLite storage.

Chrome extension

Manifest V3, content script on Google Meet, one-click start.

Privacy & GDPR

100% local architecture, standardised consent announcement.

Building a local, confidential tool for my own interviews reflects my standards on three fronts: listening quality (no more handwritten notes), candidate-data confidentiality (nothing leaves the machine, unlike Otter.ai, Tactiq, MeetGeek or Fathom), and technical pragmatism — the right tool, not the biggest: all local, no subscription, with full control over the templates.
