Four tools dominate this category in 2026 and they are not competing on the same thing. One sells invisibility as a $149.99 add-on, one sells coaching sessions at $149 a month, one sells a lifetime licence, and one includes the invisibility on its free tier. Here is the comparison laid out, with the trade-offs stated plainly rather than hidden.
| OfferPilot AI | Cluely | LockedIn AI | Final Round AI | |
|---|---|---|---|---|
| Invisible on screen share | Every plan, incl. free | $149.99/mo tier | Supported plans | Not core |
| Entry paid plan | $39/mo | $19.99/mo | ~$29.99-49.99/mo | $149/mo |
| Free live copilot | 5 min/day | Starter | Limited | Basic models |
| Pay once | $249 / 6 months | No | ~$1,499 lifetime | $500 / year |
| AI included | Yes, 3 models | Yes | Yes | Yes |
| On-device transcription | Yes | No | No | No |
| Metered on listening time | Yes | No | No | No |
| Coding assessment flow | Yes, multi-scroll OCR | Yes | Yes | Yes |
| Mock interviews / coaching | No | No | Limited | Yes |
| macOS | No | Yes | Yes | Yes |
| Windows | Yes | Yes | Yes | Yes |
1. OfferPilot AI — best if the overlay must be invisible and you are on Windows
Operating-system capture exclusion on every plan, including free, so the overlay is absent from Zoom, Teams, Meet, OBS and screenshots while staying fully visible to you. Transcription runs on-device with Whisper, so interview audio never leaves the machine and the answer arrives in about a second. Grok, DeepSeek and Gemini all answer each question in parallel and switching between them re-asks nothing; Gemini is the recommended model for LeetCode-style problems. The clock is metered on listening time only. Against it: Windows 10 and 11 only, no macOS, and it is a newer product than the others here.
2. Cluely — best if you also want it in sales calls and meetings
The broadest use case of the four, and it runs on macOS. The catch is that screen-share invisibility sits on the Pro + Undetectability tier, reported at $149.99 a month, rather than being included.
3. LockedIn AI — best if you want a lifetime licence
An established real-time copilot on both macOS and Windows, with a rare pay-once option reported at roughly $1,499. Reported monthly pricing is around $49.99, or about $29.99 a month billed quarterly.
4. Final Round AI — best if you want coaching, not just a copilot
The most complete preparation product of the four: mock interviews, recordings, reports and AI career coaches across formats. Its copilot is sold in sessions, with a reported $149 a month for five, or about $41.67 a month if you pay $500 for a year.
How to choose in one paragraph
If you are on a Mac, the shortlist is Cluely or LockedIn AI and nothing else matters. If you want to be coached over weeks rather than assisted in the moment, buy Final Round AI. If you have one interview and want to pay once, LockedIn AI's lifetime tier is the cheapest long-run option. If you are on Windows and the single thing that matters is that the assist does not appear in the screen share while costing you nothing to verify, start with OfferPilot AI's free tier, because the invisibility is on it.
The question most buyers forget to ask
Ask what the clock measures. A tool that bills per session or per wall-clock minute charges you for the twenty minutes you spent listening to the interviewer describe the team. A tool metered on listening time only runs the clock when the copilot is actually hearing a question. Over a search with a dozen rounds, that is the difference between one plan and the next tier up.
Try it against your own round
The free plan gives you 5 minutes of live copilot a day with the capture-safe overlay switched on, no card required, so you can verify the invisibility claim on your own screen share before paying anyone anything. Download OfferPilot AI or read the plans.
