Would you use a voice AI wearable in noisy public places like cafes?
Antimattr, a San Francisco-based startup founded in 2025 by Sridipto Ghosh and Sirsha Chakraborty, is developing Project Mnemosyne, which pairs a smart ring with specialized earphones. The company has been selected for Y Combinator's accelerator programme in 2026.
Why it matters
Noisy public spaces make verbal interactions with voice AI unreliable, and Antimattr is targeting that gap with proprietary voice isolation technology. The approach could shape how wearable AI devices are designed for everyday use in San Francisco and beyond.
Project Mnemosyne combines a smart ring with earphones using proprietary voice isolation technology to filter surrounding noise. The devices begin recording only when a user manually activates them, and the source does not report independent performance benchmarks for the noise filtering.
The players
Antimattr
A San Francisco-based wearable technology startup developing voice AI hardware, reported to be the first wearable company of Indian origin to receive Y Combinator's backing.
Y Combinator
A Silicon Valley startup accelerator known for backing early-stage technology companies through its funding and mentorship programme.
WTFund
A fund led by investor Nikhil Kamath that provided an equity-free grant to support Antimattr in its early stages.
The details
The devices record only after manual activation, and raw audio is not used to train AI models. Antimattr plans to open a public beta programme in December and is working toward SOC 2 and HIPAA compliance.
Timeline
2025: Antimattr is founded by Sridipto Ghosh and Sirsha Chakraborty.
2026: The company is selected for Y Combinator's accelerator programme.
December: Antimattr plans to open its public beta programme.
The Tech Race
Antimattr's wearable extends the voice assistant model that Amazon Alexa and Apple Siri popularized into always-available hardware. Its focus on noise isolation addresses a limitation those cloud-based assistants have not solved for crowded public settings.
If the public beta opens as planned, users could test a ring-and-earphone setup for speaking to AI in loud places. Buyers should watch for final pricing and independent evidence of how well the noise isolation works in practice.
The takeaway
Wearable voice AI will only be useful if it works in the messy environments people actually live in. Antimattr's bet is that noise isolation, not just the AI model, will decide whether these devices succeed.
What happens next
Antimattr plans to open its public beta programme in December, which will be the next checkpoint for the product.
