Vibrators that sync with companion chatbots have become relatively common, allowing AI to ‘control’ vibration intensities as interactions get steamier. Now an AI vibrator that flips this directional flow is being developed.
Devin is a US startup developing a sensor-laden vibrator, designed to sync natively with its own app of interactive AI audio stories. According to the Boston Business Journal, the sensors “can measure the lead-up to orgasm and the strength of an orgasm”, and Devin’s site promises: “The audio responds to your arousal in real time.”
Devin’s site also says “Product features are still in development and may be changed”, and its FAQ is blunter about the part that matters most: “Body-responsive features are still being developed and tested.” So the control flip is a stated goal for now, not a working feature.
Letting bodily arousal steer an AI story makes sense on paper. Syncing tech so far has almost always run the other way, with a sex toy’s intensity set by whatever it’s synced to, be that a video or an AI companion. Devin will do that too (its FAQ says “We’re designing the device to match the story through changes in vibration, rhythm, and intensity.”), so the arousal sensing would sit on top of the usual sync.
Devin’s site lists male and female voices for the app, and Hewett told the Business Journal its catalog of “voices, accents and situations” includes “billionaire boss”, “professor-student”, “best friend confesses his love” and “enemies-to-lovers”.
Devin’s founder and CEO, Morgan Hewett, observed that many single women around her were creating AI companions as well as buying and using vibrators, and decided to combine the experiences. She’s certainly not the first to bring the two together, with companies like Lovense going big on chatbot syncing. Arousal sensors in a vibrator aren’t new either: GetRude’s vibrator is built to adapt its stimulation to arousal signals, and Lioness records arousal through pelvic contractions. Feeding that data into the story itself is where Devin could carve out a niche.
The company was formed in December 2025 and sold out the first run of 1,000 prototype units through what the Business Journal calls “paid pre-orders”. It estimates that the vibrator will be delivered in 2027. Anyone ordering now pays nothing up front, though. Devin’s preorder page says “Pay $0 today” and charges the $249 device price only when the vibrator is ready to ship.
The Business Journal reported that Devin was planning to test its prototype with up to 15 women. While Devin’s site features images that appear to be digital renders of the vibrator, an actual product shot isn’t yet featured.
The Devin vibrator is listed at $249 on its preorder page, which puts the device on the premium end of the vibrator scale before any app costs. That’s deliberate. Hewett told the Business Journal she was betting women would pay more than the average $150 they spent on vibrators. “I wanted to combine what was happening with romance tech and these romantic characters that women were having these online relationships with, with the profitability of the vibrator industry, and find a way to make this into a subscription-based product,” she said. The preorder page offers only two free weeks in the app, though, and says “App pricing will be announced before you choose a paid plan.”
Devin’s site promises “Hundreds of AI-personalized fantasies” and characters to choose between, though its FAQ adds: “The size of the launch library isn’t final yet.”
Hewett also told the Business Journal that Devin plans to store data on both the user’s phone and the vibrator “to minimize the risk of hacking if data is stored in the cloud.” That’s the right instinct for arousal data (the alleged MyLovely.ai breach showed what’s at stake when explicit AI chats sit on a server), but it isn’t a commitment yet. “That being said, our data storage plans are not finalized yet,” she added.
Devin bolstered its storytelling muscle recently by acquiring the AI-native storytelling startup Piffle, with Piffle co-founder Seema Lakhani joining Devin as co-founder and COO. Devin also raised $1.5 million in a pre-seed round in July, including a $500,000 check from Boston venture firm Blue Tulip Ventures.
“Most vibrators are only focused on physically turning you on,” Hewett said. “For us, it’s about engaging the mind.”
