A practice partner for job interviews
Your answers,
untangled
Speak your answer out loud, and Unramble shows the structure behind it: what set the scene, what you actually did, where you drifted. It runs entirely on your laptop.
Free to run. One-time setup: Ollama with Gemma 3 4B. The checklist waits on the next screen.
Example feedback from a practice interview for a product manager role
“Tell me about a time a launch was slipping. What did you do?”
Our mobile checkout conversion had dropped for two sprints straight.My task was to find the cause before the holiday release.Umm, so basically I, I looked at the funnel data with the payments team.I found that one failed card retry was looping users back to the cart.We shipped the fix in three days and conversion recovered to its previous level.

A straighter version
“Checkout conversion dropped for two sprints. I owned finding the cause before the holiday release, traced the funnel with payments, and isolated a card-retry loop. We fixed it in three days and conversion recovered.”
Coach’s tip: Cut the opening hedges and land the result number first.
What runs on the laptop
Three local pieces do all the work. That is the whole point: an interview rehearsal is private, and it should stay on your machine.
- Gemma 3 4B, via Ollama
- Generates your questions and scores every answer. It runs on this machine's CPU or GPU through Ollama, and swapping the model is one environment variable.
- Whisper, via transformers.js
- Turns your voice into text on the spot. The weights download once into the project folder and keep working with the WiFi off.
- Your browser's microphone
- Records the take, decodes and resamples it locally, then lets it go. There is no server to upload to.
