About Sesame AI
Sesame AI makes personal intelligence agents designed to feel like conversational partners rather than task-chasing assistants. The free iOS research preview, released May 27 2026, ships four distinct agents — Maya, Miles, Simone, and Charlie — each running on a curiosity engine that keeps dialogue moving on its own instead of waiting for a prompt. The pitch is ambient intelligence: agents built for the in-between moments, where you think out loud, follow a thread, and land on something unexpected. Voice quality is the whole point here. Sesame's research blog on crossing the uncanny valley of conversational voice lays out how the team engineers presence — the sense that someone is actually on the other end of the line, not a script reading back at you. An accompanying getting-started guide walks new users through opening conversations with each of the four agents and answers the obvious first questions, and a Discord server handles feedback and troubleshooting. It runs on iOS today, as a research preview rather than a finished product. For developers, Sesame has published open-source model weights so the underlying architecture can be poked at and studied. The stated long-term goal is intelligent eyewear — all-day comfort, high-quality audio, hands-free talking to your agent — with a 2027 arrival. That hardware does not exist yet, and no price has been announced for it. The company describes itself as an interdisciplinary team of artists, makers, and engineers, and that framing matches where the product invests: personality and conversational feel over integrations or output. Sesame sits between companionship AI and ambient intelligence — a free, expressive counterweight to mainstream voice assistants and generic AI companions, with the productivity crowd pointed elsewhere.
Behind the Verdict
Sesame is the rare AI product where the demo is the strategy. The iOS preview exists to put its conversational-voice work in your hands, and it's free, so the evaluation is quick and cheap: talk to Maya, Miles, Simone, or Charlie for twenty minutes and decide whether the presence claim holds up for you. We'd reach for this when the goal is the conversation itself — thinking out loud while walking, letting a thread wander, noticing where a curiosity engine takes an exchange that a task-first assistant would have ended two turns earlier. The getting-started guide is worth skimming first; the agents are easier to appreciate once you know what they're built to do. Where it bites: this is a research preview on iOS, not a productivity tool. If your actual need is summarization, scheduling, code, or document work, Sesame is the wrong download — mainstream assistants handle that today, and Sesame isn't pretending otherwise. The comparison that matters most is against companionship AI apps. Those usually sell emotional attachment; Sesame sells voice quality and ambient presence, with a stated hardware endgame rather than a subscription relationship. The open-source model weights make it genuinely interesting to tinkerers in a way most consumer voice apps aren't. Then there's the hardware. Eyewear in 2027, hands-free, high-quality audio — a roadmap, not a product. Anyone who needs a wearable now should pass and revisit in two years. The company hasn't published a price for it, and we won't guess one. One caveat worth repeating: everything current here is the preview. Agents, voices, and capabilities can shift as research moves, so treat any specific behavior you love as provisional rather than locked in.

Curious individuals and iOS users who want to try lifelike conversational AI without any cost or commitment.
What this tier adds
This is the free entry point, offering access to all four agents and the curiosity engine, with no paid features or trial period.
Where the pricing makes sense
The company stage and team size where Sesame AI's pricing actually pencils out — and where peers do it cheaper.
Sesame AI is free right now, which is unbeatable for curious individuals. But that generosity reflects its early stage—there are no paid tiers to compare. Once eyewear arrives in 2027, expect premium hardware pricing similar to other AR wearables. For now, you get more value from free AI companions like Replika (freemium) or voice assistants like Alexa (free with hardware), but Sesame offers a more human-like voice experience.
Setup time & first value
How long it actually takes to get something useful out of Sesame AI — broken out by persona, not the marketing-page minute.
On iOS, you can download the Sesame app and start talking to an agent within 2-3 minutes. There's no account creation required—it's a simple preview. For developers, setting up the open-source models takes a few hours, depending on your experience with ML tools. The getting started guide helps you make the most of the agents quickly.
Switching to or from Sesame AI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From major voice assistants (Siri, Google Assistant): Just switch to the Sesame app on iOS; there's no data to migrate, and you'll notice a more human-like conversation style almost immediately.
- ↗To Replika or Character.AI: If you want a more task-oriented companion, you can continue using Sesame for fun and supplement with a productivity assistant like Siri or Alexa.
- ↗To open-source voice assistants (e.g., Mycroft): Sesame's open weights can be used as a foundation for your own setup, so you're not locked in.
