Build custom AI chatbots and agents trained on your own data
Create fully functional AI agents in seconds from a visual, no-code interface without engineering help.
Connect multiple data sources so the bot answers from your own documents, help content, and websites.
Automate customer actions and build autonomous systems that require minimal human oversight.
Move complex chats to live agents and collect structured data through chat-based forms.
One unified API for 100+ AI models, with insurance when output disappoints
Access Claude, GPT, Gemini, Grok, DeepSeek, Qwen and more from a single endpoint, sourced from official providers or authorized cloud partners — no proxies and no degraded copies.
Hallucinated output, excessive latency and low throughput are automatically compensated, and each compensated case is anonymized and returned to you as a bad-case sample.
Enable ZenMux Auto and the system analyses each prompt to pick the model that delivers the best quality at the lowest cost, balancing the quality/price trade-off for you.
Multi-provider failover with capacity reserves keeps applications running when a channel rate-limits or fails, while Cloudflare edge acceleration reduces latency worldwide.
Offers a similar multi-model API gateway with broad frontier model support, but features a more established developer ecosystem.
