As AI assistants increasingly permeate our daily lives, the Limitless Pendant is gaining attention for its novel approach. This pendant-style AI device records conversations throughout the day, ensuring no important moments are missed. Developed by Limitless, the company pivoted from Rewind AI in April 2024, making a bold shift from desktop-centric to wearable devices1.
The company made its official announcement on April 15, 2024, and secured over 10,000 pre-orders within just 24 hours2. The device’s standout feature is its support for transcription in 103 languages, including full Japanese support3. The device is priced affordably at $99 standalone, with shipping scheduled to begin in August 2024.
From Rewind to Limitless: The Bold Pivot Story
Limitless’s predecessor, Rewind AI, was founded in March 2020. Founder Dan Siroker rebranded the company to Limitless with a clear vision: transitioning “from local & desktop context to cloud & audio context”1.
Behind this pivot was growing user demand to utilize AI assistants beyond desk work scenarios. Siroker first posted the pendant idea in October 2023 and achieved product realization in just a few months.

Comprehensive Privacy Protection
Limitless Pendant is designed with privacy protection as its top priority. Key features include:
- HIPAA-compliant medical-grade privacy protection5

- Limitless Confidential Cloud: Secure cloud storage

Pricing Structure
Limitless offers flexible pricing plans:

Unlimited Plan ($29/month)

While the device can be used standalone, combining it with the Unlimited plan unlocks the full potential of the AI assistant.
Japanese Language Support
Limitless Pendant supports 103 languages, including Japanese. However, according to actual user reviews, Japanese support still has room for improvement:
- Japanese conversation transcription is possible, but recognition accuracy is lower compared to English
- No dedicated Japanese templates are provided
- Advanced features like meeting minutes creation require detailed instructions each time
Currently, Limitless Pendant is optimized primarily for English-language environments, and further application improvements are needed for full-scale business use in Japanese. Particularly for meeting minutes creation, the functionality falls short compared to competing products.
Funding and Future Outlook
Limitless has raised over $33 million from top Silicon Valley investors including Sam Altman, First Round Capital, Andreessen Horowitz (a16z), and NEA4. Sam Altman has been investing in the company since its Rewind AI days, showing strong confidence in its potential.
From the April 2024 announcement to the August shipping date, the company is steadily progressing with development. They plan broader shipping in Q4 2024, aiming to establish their position in the wearable AI assistant market.
Limitless Pendant represents a bold vision for AI’s role in augmenting human memory and productivity. At $99 with 10 hours of battery life and seamless integration across platforms, it offers a compelling value proposition for professionals drowning in information overload. The device’s ability to capture, transcribe, and make searchable every conversation throughout your day addresses a fundamental human limitation - our imperfect memory.
Dan Siroker’s journey from Optimizely to Limitless shows strategic evolution: from optimizing websites to optimizing human cognition itself. With $33 million in funding from Sam Altman and other top investors, the company has the resources to realize its ambitious vision. However, success will depend on navigating privacy concerns, improving multilingual support beyond English, and convincing users that wearing an AI pendant is worth the social implications. If Limitless succeeds, it won’t just be another gadget - it will fundamentally change how we interact with information and each other.
Pivacy considerations, affordable pricing, and numerous practical features are crucial elements for the adoption of wearable AI devices. Having already secured over 10,000 pre-orders before the August 2024 shipping date demonstrates high market expectations. All eyes are on whether Limitless Pendant will become the new standard for AI assistants.
On December 5, 2025, Meta announced its acquisition of Limitless, and standalone Pendant sales were subsequently discontinued.
