Sesame

Sesame is a voice AI app that lets you hold natural spoken conversations with personal agents named Maya, Miles, Simone and Charlie, built for curious people who would rather talk an idea through than type it. Its reputation comes from how human the voices sound: Sesame's research on what it calls voice presence focuses on timing, tone and knowing when not to interrupt. Where most assistants treat voice as a feature on top of a text chatbot, Sesame treats conversation as the product.

What is Sesame used for?

People use Sesame as a thinking partner they can talk to out loud. The agents follow the thread of a conversation and can take small actions along the way, so a chat can end with notes and reminders rather than nothing.

• Exploring a topic you are curious about, from a quick answer to a long deep dive
• Brainstorming out loud and having the agent connect ideas and suggest next steps
• Rehearsing a hard conversation or a big call with a sounding board that asks questions
• Searching the web, creating notes, setting reminders and summarizing takeaways during a call
• Drafting and sending emails and managing calendar events through Gmail and Google Calendar, with your approval

Who Sesame is best for

Sesame suits adults who enjoy talking more than typing: commuters, walkers, people who think out loud, and anyone who has found other voice modes stilted. It is also interesting for builders and researchers following the state of conversational speech. It is less suited to people who need a work assistant for long documents or spreadsheets, and the App Store listing carries an 18+ age rating, so it is not for kids.

Sesame pricing

Sesame is free as of October 2026. The App Store lists the iPhone app as free, and the company describes the current release as a preview. Sesame does not publish a pricing page, and it has not announced paid tiers or a public API for its voices, so pricing may change as the product moves out of preview and into the eyewear it is developing. Check the app listing for current terms.

Limitations to keep in mind

• The app is a preview and features may change quickly
• The App Store build is iPhone only, even though the website mentions Android
• Conversation data can be used for memories and, if you opt in, to improve models; use incognito mode for sensitive chats
• There is no developer API or business plan to build on yet

Sesame vs alternatives

Pi from Inflection is the closest match in spirit, a supportive conversationalist that is free and calm, though its voice is less expressive. ChatGPT's voice mode is the better pick if you also need strong reasoning, file analysis and a large ecosystem of tools. ElevenLabs is the choice if you want to build your own voice agent or clone a voice for a product rather than chat with a ready-made one. Google Gemini makes sense if you live in Google's apps and want deep Android integration. Sesame wins when the quality of the spoken conversation itself is what you care about most.

Tips for getting started with Sesame

Try each of the four agents for a few minutes before settling on one, since their personalities differ noticeably. Use headphones in noisy places so turn-taking works as intended. Connect Google apps only if you plan to use email and calendar tasks, and switch on incognito mode for anything you do not want remembered.
