Pricing
FreemiumRetell AI's Pay-as-you-go plan starts at $0 with $10 in free credits, no commitments, and full platform access. AI Voice Agents cost $0.07-$0.31 per minute depending on the LLM and voice provider selected, with a base cost breakdown of $0.055/min for Retell's voice infrastructure, $0.015-$0.040/min for text-to-speech (ElevenLabs is priciest at $0.040/min), and LLM costs ranging from $0.003/min (GPT 5 nano) to $0.16/min (GPT 5.5). AI Chat Agents start at $0.002+ per message. The plan includes 20 free concurrent calls, with additional concurrency at $8/month each; the first 10 knowledge bases are free, then $8/month each; phone numbers cost $2/month and verified numbers have a one-time $10 fee. Add-ons include Knowledge Base (+$0.005/min), Batch Call (+$0.005/dial), Branded Call ID (+$0.10/outbound call), Advanced Denoising and Safety Guardrails (+$0.005/min each), PII Removal (+$0.01/min), and AI Quality Assurance ($0.10/min after 100 free minutes). The Enterprise plan offers custom pricing with dedicated stable servers, custom SSO, role-based access control, custom MSA/DPA/BAA terms, high concurrent call caps, and 24/7 support with a dedicated portal.
FreemiumBotpress offers four main tiers. Pay-as-you-go is free with no base subscription, including one collaborator seat, a monthly AI credit, and usage billed as AI Spend beyond that credit; it's best for prototypes and small tests. Plus starts at $89/month and adds live-agent handoff, white-labeling, and WhatsApp deployment. Team starts at $495/month and adds real-time collaborative editing, role-based access control, and workspace management, with roughly $1,000 worth of add-ons bundled in. Enterprise is custom-priced for large organizations, adding white-glove onboarding, a dedicated support manager, formal uptime SLAs, and custom workspace, message, and storage limits. Pay-as-you-go add-ons are also available a la carte (for example, extra table rows, incoming messages, or bots). As of a May 2026 pricing update, workspaces created after May 14, 2026 get unlimited bots and bundled AI Spend included on every paid plan; existing workspaces keep prior pricing. Additional storage can be added to Plus and Team plans for $40/month.
