For the LLM layer: OpenAI GPT-4o, Anthropic Claude, and Google Gemini, depending on use case. Claude is preferred for enterprise products with document analysis requirements or stricter content controls. GPT-4o for fast, high-quality general-purpose conversational products.
For chatbot infrastructure: Dialogflow CX for complex multi-turn flows, RASA for fully on-premise deployments, AWS Lex for AWS-integrated builds, and Azure Bot Service for Microsoft-stack enterprises.
For voice: Deepgram for STT, ElevenLabs or Azure Neural TTS for natural-sounding voice output, and Agora for real-time audio infrastructure requiring low-latency performance.
We recommend the right platform in the scoping session based on your existing tech stack, compliance requirements, and use case, not based on which platform is easiest for us to build on.
