Testing sex toys for a living is easily one of the coolest perks of my job, and whenever a new piece of tech lands in my hands, I’m here to give you the honest, unfiltered tea. My latest test drive? The SensOn S1 AI Sex Toy — and I definitely have some thoughts.

Before we get into it, here’s why you can trust my review: I’ve been testing sex toys for years across various outlets, and I have hundreds of toys in my apartment that have either gone under extensive testing or are waiting to (stay tuned!). I hold a certificate from Sextech School, and as someone living with endometriosis and interstitial cystitis (IC), I’m pretty particular about what I recommend for people with pelvic pain. 

That said, it’s important to keep in mind that pleasure is subjective. Not everything that works for me will work for you and vice versa. However, my notes can help you decide whether or not the SensOn S1 AI Sex Toy is worth your hard-earned cash.

What is the SensOn S1 AI Sex Toy (and how does it work)?

According to the product description, the SensOn S1 is a three-in-one, hands-free pleasure device that uses AI to sync in real-time with your voice, your breath, and interactive erotic stories.

The SensOn S1 clicks together with its magnetic attachments, connects to a dedicated app, and gets you off via an interactive storyline with a sexy AI persona. (You can also remove the vaginal stimulator if you prefer, which is a great option for people who experience pain with penetration.)

The toy itself features three separate parts: a clitoral stimulator, a vaginal stimulator, and two nipple clamps. It arrives in a box that looks like a spaceship or “The Bean” sculpture in Chicago. To use the toy, you have to download the SensOn App and turn on your Bluetooth.

The setup

After downloading the app, the instruction booklet tells you to hold the Core power button to turn it on and enter standby mode.

The fit

After getting the app up and running, I positioned the toy so the vaginal stimulator was comfortably inside of me. 

Finding the ideal positioning required some adjustment during my first session. The clitoral intensity did get stronger if I squeezed my thighs together.

OK, what about the AI component?

Where it gets interesting (and a bit unhinged). The app asks you to select your preferences, including exactly what you like and what you want to avoid. You can curate your mood by power dynamic (“MSub,” “FSub,” “MDom,” “FDom”), story setting, sexual genre, and emotional feel. You can even choose character traits like “non-human” or “forbidden.”

One bizarre feature I did notice: the app restricts screenshots. When I tried to snap a few pictures of the category options for this review, a pop-up scolded me. I’m not sure whose privacy this is protecting, considering these are AI bots and not real people, but it’s worth mentioning. (Editor’s note: We did reach out to the brand, and SensOn responded, “As our community continues to grow and with the upcoming launch of new user-created characters, we have received similar feedback from users. We plan to remove this restriction as soon as possible and provide users with greater flexibility in sharing their experiences.”)

Are the AI stories any good?

The voices themselves are genuinely sexy, and contrary to my initial expectations, they are very NSFW. Usually, AI is heavily censored, but there’s no holding back on the F-word here, which was kind of fun.

The idea of AI erotica that’s personalized is really interesting, and we’ll likely be seeing more of that. But the tech itself just doesn’t hold up, yet. I tried “chatting” with multiple AI personas. One female AI kept whispering “good girl” in my ear (I was wearing headphones), and I admit, it got me hot. 

Some of the scenarios are a bit ridiculous, while others can be triggering, so just an FYI. 

Like, wow! Okay! Tldr; the AI erotica component can get really filthy, really fast. It skews more graphic, and sometimes, even violent (yes), and that isn’t for everyone. The AI tech itself needs some work, but I imagine that as the toy learns from more usage and more time being on the market, it’ll adapt and evolve. It’s also very possible that after using it for a prolonged period of time, it will learn my preferences—that’s the goal, at least.

A quick feature recap

If you’re lost, that’s OK! I know there’s a lot of info in here. Here’s a quick breakdown of what the SensOn S1 is supposed to do: 

Is the app free to use?

Buying the physical toy doesn’t give you full access to the tech. The app has two paid subscription tiers:

Who is this best for?

The SensOn S1 AI Sex Toy is probably best for die-hard tech nerds who love novelty gadgets. I’ll be honest and say this is for more kink-forward folks who have an open mind about foreplay and erotica, and aren’t hesitant about boundary-pushing dirty talk. It could also appeal to people curious about AI-driven intimacy and personalized interactive storytelling. Sometimes the dirty talk gets really, really dirty (even dirtier than you directed or are comfortable with), so that’s definitely something to keep in mind. I will say, it’s the most innovative sex tech on the market right now, and I can only imagine it’ll get more refined in the future.
