“It picked up what I was coding and flagged edge cases I would’ve missed. Saved me mid-round.”
“STAR prompts made my answers tighter—less fluff, more signal. I felt noticeably more confident.”
“Latency is the best part—it feels like an invisible coach. No awkward delay, no context loss.”
“Privacy-first was the deciding factor. Local overlay + clear controls gave me real peace of mind.”
“Perfect pacing in system design. When I got stuck, the hints nudged me back to the right layer.”
“The overlay is subtle and doesn’t distract. Feels like notes—not a ‘bot’ running in the meeting.”
“For coding rounds, the reminders on complexity + corner cases are gold. I moved faster and cleaner.”

Keep your budget focused where it matters: fair pricing, strong experience. We keep refining the product so every interview feels more controlled.
Start with a 3-day free trial, then decide. One real interview workflow is enough to feel the difference.
Start Free Trial arrow_forward
The 3 things candidates
want clear
before a live interview
Candidates usually want clarity on setup, privacy boundary, and fit, then a free trial before deciding whether to bring it into a real interview.
Validate the share-safe setup
Proof matters more than slogans. Rehearsing the exact screen-share and stealth path on your target platform is what reduces surprises in a live round.
Know the privacy boundary
Local-first by default. Sensitive context stays on-device wherever possible, with encrypted transfer paths and a clear privacy policy you can review first.
Try it free before you decide
It is not only for coding roles. Whether your loop is coding-heavy, system design, behavioral, or business-facing, start with the free tier and decide after trying the core workflow yourself.
