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.

Customer insight and creative testing powered by AI personas
Create AI personas that represent your target customers, then query them to explore perceptions, preferences and reactions.
Run synthetic research and surveys to gather fast feedback on concepts, copy and creative before committing budget.
Test advertising, messaging and creative ideas against AI personas to see what resonates before launch.
Analyse research responses and turn them into structured insights for segmentation and positioning decisions.
