Miles AI is an advanced voice-based AI companion developed by Sesame, featuring a highly realistic male voice persona (alongside the female Maya). Available through the Sesame app preview, Miles AI excels at natural, emotionally intelligent conversations that feel remarkably human-like, handling everything from casual chats and personal advice to in-depth discussions with contextual awareness, pauses, tone variations, and genuine engagement.
Is Miles AI Free or Paid?
Miles AI is currently offered as a free research preview through the Sesame platform, allowing users to chat via voice without any cost during this early access phase. There are no paid subscriptions required to access Miles or Maya at present, though future public releases may introduce premium tiers for advanced features, unlimited usage, or priority access as the product matures beyond preview.

Miles AI Alternatives
If Miles AI‘s voice realism or preview limitations don’t fully suit your needs, here are leading alternatives in the conversational voice AI space:
| Alternative Tool Name | Free or Paid | Key Feature | How it Compares to Miles AI |
|---|---|---|---|
| Grok (xAI) | Free with limits, paid upgrades | Witty, real-time knowledge, multimodal capabilities | Strong text-based humor and info access; less emphasis on ultra-natural voice presence compared to Miles AI’s emotional voice focus |
| ChatGPT Voice (OpenAI) | Free tier + Plus ($20/month) | Versatile voice mode with natural speech, memory, integrations | Broad utility and reliability; good realism but often feels more scripted than Miles AI’s dynamic, human-like subtlety |
| Google Gemini Live | Free with Google account, advanced via Gemini Advanced | Real-time voice chat, multimodal (camera/screen share), Google ecosystem tie-in | Excellent for practical tasks and live collaboration; slightly less “emotional depth” in casual dialogue versus Miles AI |
| Pi (Inflection) | Free | Empathetic, supportive conversations with memory | Focuses heavily on emotional support and friendship; similar warmth but text-primary with voice add-on, not as breakthrough in voice realism |
| Claude (Anthropic) Voice | Free tier + paid Pro | Safe, thoughtful responses with voice mode in app | Prioritizes helpfulness and ethics; solid voice but more measured tone, lacking some of Miles AI’s uncanny natural flow |
