With Dazzle, Marissa Mayer bets your camera roll has more info on your life than your inbox

When former Yahoo CEO Marissa Mayer earlier this month told me she was finally ready to unveil Dazzle, the personal AI assistant that raised an $8 million seed round last December, I couldn’t help but wonder if she’s playing copycat to Meta’s Muse, Instinct, and the wave of similar tools that have flooded the market over the past month.

But when Mayer finally gave me a demo, Dazzle proved it’s taking a different approach. Instead of building context about you from text-heavy apps like email, calendars and shopping histories, Dazzle’s AI assistant gets all its context from a single source: your camera roll.

“I think that photos are an underappreciated source of information,” Mayer said. “You’ll be surprised what we can learn about you and how good a job we can do with your photos.”

Mayer argues that if a photo is worth a thousand words, your camera roll is worth millions. By analyzing all the photos stored on your phone, Dazzle claims to understand your hobbies, interests, food and style preferences, how you like to spend their time, and with whom.

“We understand whether or not you like to ski, where your most recent trip was, what types of things your kids are into,” Mayer said.

It’s no surprise that Mayer has built an assistant centered around photos. Her previous startup, Sunshine, launched an AI-powered photo-sharing tool called Shine in 2024. While that product was widely criticized for its outdated design, failed to attract widespread usage, and eventually shut down, Mayer says it nevertheless built “interesting IP.”
