Undetectable AI assistant for live technical interviews
The assistant transcribes the question as it is asked and returns a working solution you can read from the overlay, aimed at LeetCode-style prompts.
Captures and transcribes the interviewer's speech so the AI can follow questions delivered verbally during the call.
The window stays out of screen shares, dock, taskbar and the activity monitor, with click-through behaviour and a disguised process name.
Targets coding, system design, behavioural, full-stack, data, AI/ML, consulting, trading and product interviews rather than only algorithms.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.

Offers robust serverless inference and GPU clusters for open models, but features a narrower selection of proprietary models.


Real-time AI interview copilot that answers while you are still talking
Features adaptive LLM routing and automatic failover, but lacks OpenRouter's massive ecosystem of community-rated model endpoints.
SpecialistDelivers exceptional inference speed and high-throughput performance for open models, but focuses primarily on hosted weights rather than multi-provider aggregation.

Free / Open-sourceProvides self-hosted and Python SDK control over 100+ LLMs, but requires setting up your own infrastructure.


SpecialistLow-cost serverless inference APIs for 200+ open models

One unified API for 100+ AI models, with insurance when output disappoints

AI interview copilot with real-time answers and automatic debriefs
Real-time AI copilot for interviews, meetings and coding rounds
One API for fast, cost-predictable inference on LLMs and multimodal models

Aggregates hundreds of foundation models and agentic tools under one endpoint, but lacks OpenRouter's community popularity and extensive prompt tuning.
