The Best Free AI Interview Assistant in 2026

Most "free" AI interview assistants are actually limited trials: you get a few minutes or one session, then hit a paywall. A genuinely free option is one that stays free forever. In 2026, the best truly-free route is a private assistant that runs locally or with your own key (BYOK), with no subscription.

"Free" vs. Free Trial: The Distinction That Matters

Before comparing tools, understand the trap. Many competitors advertise a "free" tier that is really:

• A time-limited trial — a few free minutes, then a subscription is required.
• A stripped-down demo — no real-time help, preparation only.
• Freemium with caps — a limit on sessions or questions per month.

A genuinely free tool has no timer, no session cap, and asks for no card.

The Genuinely Free Options in 2026

1. Haggle (local via Ollama) — free forever

Haggle provides a free local-first tier. Run it with Ollama and a local model (Llama, Mistral, CodeLlama, Gemma) and the cost is exactly $0, forever, no card, no session cap. Everything runs offline on your device. It is the only option on this list that involves paying for nothing at all.

2. Haggle (BYOK) — free app, pay only for tokens

If you prefer cloud-model power, Haggle's BYOK (bring-your-own-key) mode lets you connect your own OpenAI, Anthropic, Gemini, or Groq key. The app itself is free — you pay only the provider for the tokens you use, often cents per session. No subscription.

3. General chatbots (ChatGPT/Claude free tiers)

The free tiers of ChatGPT or Claude can be used for interview prep, but they are not built for live help: no overlay, no screen capture, you have to copy questions manually. Fine for practice, not for real time.

Why Local-First Is the Best Free Route

A free, local-first tool gives you three things a trial can't: durable zero cost, full privacy (no data leaves the device), and complete data sovereignty. For candidates running many interviews, that's the difference between a predictable $0 and a mounting subscription.
