Pricing
FreemiumBland uses per-minute pricing with no token charges or model-provider pass-throughs. Start: free, $0.14/min talk time, $0.05/min transfer time, 10 concurrent calls, 100 calls/day, 1 voice clone, 10 knowledge bases, no card required. Build: $299/month platform fee, $0.12/min talk time, $0.04/min transfer time, 50 concurrent calls, 2,000 calls/day, 5 voice clones, 50 knowledge bases. Scale: $499/month platform fee, $0.11/min talk time, $0.03/min transfer time, 100 concurrent calls, 5,000 calls/day, 15 voice clones, 100 knowledge bases. Enterprise: custom, contracted to volume, with concurrency sized to need, on-prem/VPC deployment, forward-deployed engineers, BAA, SSO, and data residency options. Every plan's per-minute rate bundles the LLM, real-time speech-to-text, and premium text-to-speech voices/clones; telephony is billed separately at pass-through cost unless customers bring their own Twilio account (BYOT customers pay no transfer fees). Higher tiers add SMS/Web Chat, appointment scheduling nodes, warm and live transfers, guardrails, alarm monitoring, and compliance features like BAA and SSO.

Bland AI

Bland AI Pros & Cons

Pros

  • Fully in-house voice, LLM, STT, and TTS stack delivers roughly 400ms latency, well below the reported industry average
  • Free Start plan with no credit card required makes it easy to test the platform before committing
  • Simple all-in per-minute pricing bundles the LLM, speech-to-text, and text-to-speech with no separate token charges
  • Strong compliance posture with SOC 2, HIPAA, GDPR, and PCI DSS certifications built in from the start
  • Norm AI assistant and pre-tested Conversational Pathways speed up building agents without voice AI experience

Cons

  • Fully proprietary model stack means customers cannot bring their own LLM, such as OpenAI or Anthropic models, unlike some competitors
  • Build and Scale plans carry monthly platform fees on top of per-minute usage, which adds cost for lower-volume users
  • Advanced features like warm/live transfers, guardrails, and custom dialing are gated behind paid tiers, unavailable on the free Start plan
  • Enterprise-grade deployments with on-prem/VPC and forward-deployed engineers require custom, quote-based contracts
