AI Interview Copilots Compared on AI Models (2026): Who Names GPT, Claude and Gemini

Of the nine competing AI interview copilots we checked on November 13, 2026, three name their language models on their own sites and let you choose: Verve AI lists 12 models from Anthropic, OpenAI, Google and others, LockedIn AI's picker spans ChatGPT, Claude, Gemini, Grok, DeepSeek and Kimi, and Parakeet AI offers GPT, Claude and Gemini models from a dropdown. Final Round AI, Sensei AI, Interview Coder, Beyz AI and Cluely name none, and Hedy AI names its transcription engines rather than its language model. Our pick is CoPilot Interview, which we make, because speed and the context the model is given matter more than the brand, and its model options by plan are published on its pricing page.

Which models each copilot names

Competitor details are as each vendor listed them on its own site on November 13, 2026, in US dollars for a US visitor. They change often, so confirm before you pay. Hedy AI's transcription details come from its help centre, read on November 12, 2026.

What the model changes, and what it does not

An interview copilot runs two kinds of model: speech-to-text turns the question into text, and a language model writes the answer. The second is the one vendors advertise, but the first decides whether the answer is to the right question.

• Speed against depth. Parakeet AI's FAQ says lighter models respond faster and larger ones give more detail; LockedIn AI's recommended default balances the two.
• Newest is not always best. LockedIn AI notes that the highest version number is not automatically the best pick for an interview.
• Context matters more than brand. An answer built from your résumé and the job description beats a cleverer model working from the question alone.
• Transcription comes first. A misheard product name produces a fluent answer to the wrong question, whatever the model.

Which AI models power AI interview assistants explains the full pipeline.

Questions to ask any vendor about models

1. Which language models can I use on the plan I am paying for, and which are add-ons?
2. Which model is the default, and why?
3. Which speech-to-text engine hears the call, and does it handle my accent and field's jargon?
4. Is my transcript sent to the model provider, and is it used for training?
5. Can I compare two models on the same question? An assistant with two AI models shows why that helps.

How to test models on your own questions

1. Pick three questions from your own field, including one with a niche term.
2. Ask each in a practice session with the default model, then with the fastest and the largest you can choose.
3. Time the answers and mark which ones you could actually say aloud.
4. Read choosing a model in your AI interview assistant for what to look for.
5. Weigh speed alongside quality; AI interview copilots compared on answer speed lists each vendor's claim.

Where CoPilot Interview fits

CoPilot Interview is an interview copilot built as a desktop app for Windows 10 and 11 and macOS 12 or later, with a browser demo at /try, an iPhone practice app in TestFlight and an Android APK beta. It runs as a separate window, listens to the call and your microphone, and shows captions and a structured answer in about two seconds. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included. Paid plans are Standard at $24.99 a month and Pro at $39.99, with hour packs from $9.99, and a new subscription's first payment carries a 14-day money-back guarantee if under 30 minutes of live session time were used (refund policy). Whatever tool you use, follow your employer's rules; proctored tests, online assessments and AI-led rounds forbid outside help, so prepare for those instead.

Disclosure: CoPilot Interview is our product, so weigh what we say about it accordingly.

Frequently asked questions

Which AI model is best for interview answers?

There is no single best one. Smaller models answer faster and larger ones give more detail; the context the tool gives the model, such as your résumé and the job description, matters more than the brand.

Which interview copilots let me choose GPT, Claude or Gemini?

Verve AI, LockedIn AI and Parakeet AI, as listed on their sites on November 13, 2026. LockedIn AI also lists Grok, DeepSeek and Kimi.

Which tools name their speech-to-text provider?

Parakeet AI names Speechmatics, and Hedy AI names on-device Whisper or Nemotron, with Deepgram, OpenAI or xAI if you add your own key. The others we checked name none.

Where can I see CoPilot Interview's models?

Its model options by plan are listed on its pricing page, and our guide to which model to pick in CoPilot Interview explains them.

Does a bigger model mean a better interview?

Not on its own. A slower answer you cannot use in time is worse than a quicker, shorter one, so test both on your own questions.
