Dazzle Turns Your Camera Roll Into a Personal AI Assistant

Former Yahoo CEO Marissa Mayer is taking a different approach to personal AI with Dazzle, an assistant that believes your camera roll may reveal more about your life than your inbox ever could.

Mayer recently unveiled Dazzle after the startup raised an $8 million seed round last December. While the product arrives during a rush of new AI assistants, including Meta’s Muse and Instinct, Dazzle stands apart by focusing almost entirely on one source of personal information: the photos stored on your phone.

“I think that photos are an underappreciated source of information,” Mayer said. She believes users may be surprised by how much an AI system can learn simply by analyzing their pictures.

The idea is straightforward. A single photo can contain information about where someone went, what they ate, what they enjoy doing, what they bought and who they spent time with. Dazzle attempts to connect those individual details across a user’s entire photo library.

Mayer says Dazzle can identify interests such as skiing, recognize recent travel destinations and understand what activities a user’s children enjoy. The goal is to build a picture of someone’s lifestyle without relying primarily on emails, calendars or shopping histories.

The focus on photos is also connected to Mayer’s previous startup, Sunshine. In 2024, Sunshine launched Shine, an AI-powered photo-sharing product. The service was criticized for its outdated design, failed to gain widespread adoption and was eventually shut down. Mayer has nevertheless said the company developed “interesting IP” during that process.

Dazzle can be used through its app or by text, with its features broadly divided into two areas.

For everyday tasks, the assistant can examine recent photos and extract useful information. For example, it can identify an event from a flyer in your camera roll and use the information to help populate your calendar. It can also notice something that needs fixing, such as a broken garage door, and help find a repair person.

The second part is more personal. Dazzle analyzes a user’s photo history to generate ideas, including vacation suggestions, birthday gifts and activities.

That personalization is where the product becomes more interesting. Mayer says Dazzle once analyzed her family’s photos and figured out that they enjoy escape rooms. It then recommended several locations around the San Francisco Bay Area that she had not previously considered.

In another test, Dazzle suggested Mediterranean vacation destinations based on previous trips to Spain and Greece. It even recommended Sicily, despite the trip having taken place four years earlier.

The system is not perfect, however. During testing, it failed to recognize that the user’s daughter already knew how to roller skate when asked whether buying her roller skates would make a good birthday gift.

Still, some of Dazzle’s recommendations felt surprisingly specific, including ideas such as visiting a local pottery studio or taking a bioluminescent kayak tour in Tomales Bay.

The bigger question is whether people will want an AI assistant to have access to their entire photo library. Mayer argues that photos could actually feel less sensitive to some users than giving an AI access to emails and private messages, especially amid security concerns surrounding newer AI assistants such as Instinct and Muse.

Privacy is therefore a major part of Dazzle’s pitch. Mayer says the company prioritizes privacy and discards personal information that its AI identifies as sensitive.

Dazzle is entering a crowded market, and it may not yet be as broadly useful as some competing AI assistants. But its approach points toward a different idea of what a personal AI could become — one that doesn’t simply follow your calendar or search through your inbox, but gradually understands your interests, habits and experiences through the images you’ve captured.
