When LockedIn AI might be the better fit
If your interviews are coding-only and you want to try a live copilot without paying anything up front, LockedIn AI's free-to-start desktop app is a reasonable way to test the concept before committing to a paid tool. For candidates who are purely optimizing for a zero-cost entry point into this category, that's a legitimate reason to start there rather than with a paid product like Co-Help.
When Co-Help might be the better fit
- You have system design or behavioral rounds in addition to coding.
- You want several AI models racing for the best answer rather than one model.
- You'd rather pay $20 once for a specific interview than manage a free tool's limits.
What every Co-Help plan includes
Regardless of which plan you choose — the $20 one-time session, or the discounted Monthly and Annual plans — Co-Help includes the same full feature set:
- All 9 AI models — OpenAI (GPT), Anthropic (Claude), Google (Gemini), Groq, DeepSeek, Mistral, OpenRouter, and GitHub Models, raced in parallel so the fastest strong answer wins.
- Live transcription of both sides of the call via your operating system's audio, with no microphone needed to hear the interviewer.
- Screenshot Q&A and diagram rendering for coding and system design questions.
- Your own knowledge base — resume, projects, and notes — so answers reflect your real experience instead of generic responses.
- Local-first privacy — your interview profile, conversations, and knowledge base stay on your machine; our servers keep only basic account details (name, email, hashed password, plan). AI requests are answered and then discarded, with only the timestamp, model, and request size logged for billing.
- No API keys to manage — AI access is included and managed on Co-Help's backend.
