Meet Rewind: The AI that never forgets


In a world where information overload is the norm, the ability to remember and retrieve information is more crucial than ever. Enter Rewind, a groundbreaking macOS app designed to be the “search engine for your life.” With a recent $10 million funding round led by Andreessen Horowitz, Rewind is poised to redefine how we interact with our digital lives.

The Genesis of Rewind

The story of Rewind is a compelling tale of innovation born from personal experience. The founder, who suffered from hearing loss, found his life transformed by the use of hearing aids. This experience sparked a curiosity about the potential of technology to augment human capabilities, particularly in the realm of memory and information retrieval.

The initial concept was a product named Scribe, which was designed to record meetings and make the content searchable. Scribe was a hit, but it was just the tip of the iceberg. The team realized that the technology had broader applications and could serve as a tool for capturing not just what you’ve heard but also what you’ve seen and said. This led to the evolution of Scribe into what we now know as Rewind.

The company’s journey was further accelerated by a $10 million funding round led by Andreessen Horowitz, a venture capital firm known for backing transformative technologies. This investment has enabled Rewind to expand its vision and scale its operations, aiming to make its memory-augmentation technology accessible to a broader audience.

But what truly sets Rewind apart is its commitment to ethical technology. From the outset, the company has been guided by a privacy-first philosophy. Unlike other tools that store your data on external servers, Rewind keeps all information locally on your device, ensuring that you have complete control over your data. This approach has garnered praise from industry leaders and users alike, solidifying Rewind’s position as a pioneer in the field of personalized AI.

The genesis of Rewind is not just a story of technological innovation but also a testament to the transformative power of personal experiences. It serves as an inspiring example of how challenges can be turned into opportunities, leading to solutions that have the potential to benefit humanity at large.

How Does It Work?

Understanding the inner workings of Rewind is like peeling back the layers of an intricately designed onion. At its core, Rewind is built on a privacy-first model, a feature that distinguishes it from other productivity tools in the market. All data is stored locally on your Mac, ensuring that you have full control over what is captured and stored. This eliminates the need for cloud integration, thereby reducing the risk of data breaches.

Cutting-Edge Compression

One of the standout features of Rewind is its advanced compression techniques. The app boasts a staggering 3,750x compression rate, which means even Apple’s smallest hard drive can hold years of recordings. To put it in perspective, 10.5GB of raw data is compressed to just 2.8MB without a significant loss in quality. This ensures that the app is not a burden on your system’s resources.

Intelligent Indexing

Rewind utilizes native macOS APIs and Optical Character Recognition (OCR) to index all the words that appear on your screen. This makes the data easily searchable, allowing you to find specific information with just a few keystrokes. The OCR technology ensures that even text within images is captured and indexed.

Seamless Automation

The app runs imperceptibly in the background, capturing your screen and audio. It’s designed to be a “set it and forget it” tool. Once installed, Rewind automatically compresses, transcribes, encrypts, and stores your data locally. This means you don’t have to worry about manually saving or organizing your information.

User Interactions

Rewind is not just a passive tool; it’s interactive. You can ask Rewind to perform specific tasks such as summarizing meetings, drafting emails, or even telling you what you were doing on a particular day. This is made possible through the power of GPT-4, making the AI personalized to your needs.

Resource Efficiency

Designed for Apple Silicon (M1 and M2) chips, Rewind is highly resource-efficient. While recording, it uses only 20 – 40% of a single CPU core, which translates to 1-5% of the total CPU capacity. This ensures that the app runs smoothly without affecting the performance of other applications.

By combining cutting-edge technology with a user-centric design, Rewind has created a tool that is not just functional but also incredibly efficient and secure. It’s a marvel of modern engineering, designed to make your life easier without compromising on privacy or performance.

Use Cases

The brilliance of Rewind lies in its versatility. It’s designed to cater to a wide range of professionals, each with unique needs and challenges. Let’s delve into how Rewind is revolutionizing productivity across different sectors.

For Executives: A Decision-Maker’s Best Friend

Executives are often swamped with meetings, emails, and critical decisions. Rewind serves as an invaluable tool by automatically capturing, indexing, and making searchable all meeting notes and discussions. This enables executives to surface critical information faster, aiding in more informed decision-making. The app also provides concise summaries of meetings, allowing executives to quickly grasp the key points without sifting through hours of recordings.

For Engineers: Your Personal Code Repository

Engineers face the daunting task of managing vast amounts of code, debugging, and remembering technical decisions made in meetings. Rewind acts as a personal database for everything they’ve seen or discussed. It helps in easily recovering lost code, reproducing bugs, and even summarizing workdays for standup meetings. The feature to go back and see how a complex setup was performed is particularly useful for engineers.

For Sales Professionals: Close Deals Like Never Before

In sales, information is power. Rewind allows sales professionals to record any meeting, even if they aren’t the meeting owner. This enables them to quickly recall how they know someone and what was last discussed before hopping on a call. The app also helps in surfacing what was most important to a prospect, thereby tailoring pitches to individual needs and closing deals faster.

For Individuals with ADHD: A Second Brain

ADHD can make it challenging to focus and remember details. Rewind serves as a second brain for these individuals, helping them retrace their steps when they’ve forgotten something. The app keeps everything passively organized, allowing users to easily recall something that was mentioned in a meeting or find that thing they read somewhere the other day.

For the Privacy-Conscious: Your Data, Your Control

One of the standout features across all use-cases is Rewind’s commitment to privacy. All recordings are stored locally on your Mac, ensuring that you—and only you—have access to them. This privacy-first approach is particularly appealing to those who are cautious about where their data is stored and who has access to it.

By tailoring its features to meet the specific needs of different professionals, Rewind has positioned itself as a versatile and indispensable tool. Whether you’re an executive, an engineer, a sales professional, or someone who simply wants to be more organized, Rewind has something to offer you.

The Future

Rewind is not just a tool; it’s a vision for the future where technology augments human memory, making us faster, sharper, and more present in our daily lives. With its robust features and privacy-first approach, Rewind is set to become an indispensable part of our digital existence.
