How we use AI, and how we don't
Last updated 24 July 2026. Honesty about AI is a product feature here, not a legal chore.
What uses AI today
- The tuition coach helps you shape your own experiences into clear STAR stories. It uses Google's Gemini, called only from our server for your own signed-in session. It asks probing questions and structures your words, it is barred from inventing experience you don't have, and it flags any claim your answers don't support.
- Scored mock interviews generate questions for your role and score each answer against a fixed behavioural rubric (structure, specificity, relevance, evidence, delivery). Also Google's Gemini, server-side only. Feedback is restricted to that rubric, it never comments on your emotions, confidence or personality.
- Speech-to-text uses your browser's built-in speech recognition where it has one (audio goes to your browser vendor, not to us). Where your browser can't do it, or when you speak to the coach, the recording is sent through our server to Google's Gemini purely to produce the transcript; the audio is not kept afterwards.
- Live company research uses Gemini with Google Search grounding: the model searches the web for real, current facts about your company, role and industry, and the brief shows its sources. Server-side only, like everything else.
What doesn't use AI
- Your programme is built by a deterministic engine, same inputs, same plan, every time.
- The questions to expect are selected by transparent rules from researched question banks, filtered by your role, stages and region.
- Delivery feedback (words per minute, filler count, length) is simple counting, on your device.
How your material is handled
When you use the coach or a scored mock, the relevant context, your role and company, the stories you're building, and your CV if you've added one, is sent to Google (Gemini) only for that request, only for your own session, and only when you're signed in. The key that authorises those calls never touches your browser; it lives as a server-side secret. Calls are identity-minimised: we send your first name so the coach can greet you, but never your surname or contact details, and requests are capped per day to keep the coach a practice aid, not a crutch.
What we refuse permanently
- No live-interview assistance. Intervooh will never feed you answers during a real interview.
- No fabrication. It will not invent experience, projects or qualifications for you.
- No emotion or personality inference. We do not analyse your face, read your "confidence", or score your personality, and EU law now prohibits emotion-recognition AI in recruitment contexts. We measure only what you can control: structure, specificity, relevance, evidence and delivery mechanics.
Limitations, stated plainly
- Question banks are researched and representative, but no tool can know exactly what your interviewer will ask.
- Speech recognition mishears sometimes, especially with background noise, the transcript is a practice aid, not a judgement.
- Preparation improves your odds; nothing guarantees an offer.
