A coach that keeps up
with the conversation
Everything is built around one idea: help you give a better answer to the question being asked right now.
bolt Live coaching loop
The coach continuously watches the conversation — including the words being spoken mid-sentence — and refreshes its guidance the moment the speaker settles.
- Fires within a second of a pause; even faster when it detects a question
- Keeps updating during long answers, so guidance never goes stale
- Newest-wins streaming: a new question instantly replaces old advice
radar Instant question detection
The moment a question is asked it flashes up on the stage, in full, so you never lose the thread — before the full coaching even arrives.
- Recognizes question forms: “walk me through…”, “tell me about a time…”, “why…”
- Purely visual — coaching never makes a sound during a real conversation

Mock Interview mode plays the interviewer — asking questions built from your job description and background, then following up on what you actually said.
- One question at a time, adapting to your answers — not a canned list
- Questions can be spoken aloud for realistic pressure
- Listen to a full interview — a complete Q&A with model answers from your own background, as one downloadable MP3
- Live coaching runs on your answers exactly as it would in a real interview
checklist Tailored prep briefs
Before you practice, generate a brief built from the job title, the job description, and your background — not a listicle of generic tips.
- What candidates report about this company's actual interview process — rounds, formats, question styles
- Likely questions for this exact role and level
- Strengths to lead with, mapped to specific JD requirements
- Honest gap analysis with reframing advice
- STAR stories to prepare and smart questions to ask them
