The Limitless AI Pendant is a wearable gadget designed to record audio information throughout the day. This review examines its functionalities, user experience, and potential ethical and practical implications.

Комплектация и дизайн

Устройство поставляется в минималистичной упаковке, включающей сам кулон, кабель для зарядки, ожерелье и зарядный блок. Кулон выполнен в черном цвете и крепится к одежде с помощью магнитного зажима, обеспечивая надежную фиксацию. Дизайн устройства включает массив микрофонов, направленных вверх, что предполагает запись речи пользователя и окружающих. В комплекте также присутствует док-станция для зарядки, напоминающая ранние модели док-станций Apple.

Setup and Application

The initial setup process for the application proved to be intuitively simple. The included QR code allows for quick downloading of the app from the app store. After logging into an account and connecting the pendant to the charging cable, the device is automatically detected by the application. To begin recording, press the button on the pendant, at which point a small white indicator lights up, signaling the recording process.

The Limitless application currently has basic functionality. It displays a list of recorded conversations for the day with the ability to navigate through previous and future days. Users can highlight segments of recordings for subsequent analysis using AI, as well as copy and export them in various formats (for LLM, Slack, Markdown).

AI Functionality and Data Processing Capabilities

The application offers two AI modes: a fast one and a more "intelligent" one, which presumably uses more context-aware models and operates more slowly. The current version of the application only allows questions to be asked about the content of recorded conversations. There is no ability to engage in dialogue using the model's built-in knowledge, which limits its use as a full-fledged conversational partner for brainstorming or generating new ideas.

The latest update added an audio playback feature. Beta access to a new API for developers, allowing data extraction from "lifelogs" (records of one's entire life), has also been announced.

The transcription service demonstrates good performance with English and Hindi. It is assumed that, due to the use of pre-trained models, the service supports over 100 languages.

Limitations and User Experience

Currently, the application does not support integration with custom API keys from OpenAI or other services. However, the "copy for LLM" feature allows for the export of transcribed and summarized text for further processing by external models. Users can delete unwanted segments of recordings and submit bug reports.

During 10 days of use, isolated synchronization failures of recordings were observed, which were promptly resolved by the support service. The device does not record everything indiscriminately but transmits data to the application in real-time. The recording indicator on the pendant allows for monitoring its operation.

Design and Ergonomics

The pendant can be worn on a necklace or attached to clothing using a magnetic clip. The reviewer prefers to use the magnetic attachment, finding it more convenient.

Autonomy and Heating

The device provides up to 8 hours of recording daily, with a total volume of over 4500 minutes (75 hours) of recordings over 10 days of use. The battery never fully discharged, remaining at a level of at least 40% by the end of the day. The device does not heat up during operation, which eliminates discomfort during wear.

Competitor Comparison and Company History

Limitless (formerly Scribe, then Rewind AI) was founded by Dan Siroker in 2020. Initially, Scribe focused on recording and transcribing meetings. After rebranding to Rewind AI, the company shifted to creating an application for recording everything happening on a computer screen (Mac/Windows) with a "lifelog" search function. The emergence of Microsoft Recall sparked discussions about data storage security.

Rewind AI then changed its name again to Limitless and introduced a hardware solution – an audio recording pendant. This move is seen as an attempt to enter the wearable AI device market, similar to Apple. Limitless's Mac application, unlike the pendant application, lacks AI features and "lifelog" search, indicating some fragmentation within the company's product ecosystem.

Potential Use Cases

• Habit Tracking: Recording conversations can help monitor coffee consumption or other habits.
• Shopping List Planning: Creating shopping lists and later restoring them through the app.
• Brainstorming: Capturing ideas that arise during daily activities for later analysis.
• Assistance in Critical Situations: Recording medical consultations or important conversations for better comprehension of information.
• "Rubber Ducking" for Ideas: Using the device to articulate and work through ideas in their early stages.

Ethical Issues and Privacy

The use of the device raises serious ethical questions regarding privacy and consent for recording. In Canada, where one-party consent laws are in effect, recording conversations is permissible. However, many other jurisdictions require the consent of all parties involved. The Limitless AI Pendant has a feature to automatically stop recording if consent is denied, but this does not address the issue of the absence of a default consent request.

There is a dilemma between using the device for personal development and its potential misuse in personal relationships, which could lead to conflicts. The reviewer leans towards using the device in a professional setting but questions its appropriateness in personal life.

Cost and Pricing Plans

The device's price at the time of review varies. The author purchased it for $59 as a pre-order. The standard price is$100. 1200 minutes (20 hours) of free transcription are provided monthly. Additional plans include 100 hours ($30/month or$20/year) and unlimited transcription ($50/month or$40/year).

Competitive Landscape

Similar devices exist on the market, such as the Plodd AI Notepad, which offers MagSafe attachment for iPhone and AI note-taking features. Other wearable AI devices from companies like Humane, Rabbit R1, and others are also present. However, many of these projects are facing difficulties: Narrative has ceased to exist, and Humane AI Pin was acquired by HP.

The Future of Wearable AI

The author suggests that the future of wearable AI devices lies in smart glasses, where Meta is a leader, combining visual perception with an audio interface.

Conclusion

The Limitless AI Pendant is an interesting product for those seeking to improve memory and productivity. The device boasts good hardware and basic transcription functionality. However, the company's software ecosystem requires further development, particularly in terms of application integration and unification. Ethical considerations surrounding conversation recording and consent remain a key challenge for this type of device.
