Reddit turns AI into ad fuel: what marketers should know
With AI-powered tools, Reddit offers brands a smarter way to read the room.
At Cannes Lions 2025, Reddit pulled back the curtain on a pair of alpha-stage AI tools that promise to reshape how brands mine conversations for campaign gold.
Dubbed “Reddit Community Intelligence,” the initiative taps into more than 22 billion posts and comments from the platform’s famously opinionated users.
This article explores how Reddit’s AI rollout turns community chatter into actionable insight—and what it means for marketers looking to move beyond vanity metrics and toward authentic engagement.

What Reddit just launched
Reddit introduced two new AI-driven products: Reddit insights and Conversation summary add-ons. Both are part of the company’s long-game to turn its massive trove of organic user-generated content into brand intelligence.
Reddit insights is a social listening dashboard built with Reddit-native data. It uses metadata to surface trends, sentiment shifts, and community interests in real time.
Unlike generic social listening tools, this one’s engineered specifically for Reddit’s structure—capturing nuance in niche threads and surfacing community truths beyond mere keywords.
Conversation summary add-ons show up directly under creatives in Reddit ads. They use AI to highlight relevant, genuine user commentary—essentially layering social proof directly onto paid media.
The company claims this format has already lifted clickthrough rates by 19% versus standard image ads, with brands like Lucid Motors and Jackbox Games among early testers.

Who's using it and how
Publicis is Reddit’s exclusive alpha partner, with its teams using Reddit insights to support clients like Hershey and Comcast.
According to Publicis Media Exchange US CEO Joel Lunenfeld, the tool has become core to pitch decks, planning workflows, and performance tracking. It allows agency teams to spot emerging audiences, refine brand messaging, and tap into context-rich sentiment analysis.
For example, Lucid leveraged Conversation summary add-ons to surface real Reddit chatter around its EV models in auto-focused threads—injecting relevance and credibility into otherwise standard ad units.

What marketers should know
Reddit’s new tools are early, but they point to a broader trend of platforms using AI to bring deeper community context into the brand conversation. Here’s how marketers can think ahead:
- Treat Reddit as a market research lab
With Reddit insights, you’re not just scraping mentions—you’re analyzing intent and sentiment from interest-based microcultures. Use this for everything from early product validation to creative testing.
- Test conversation add-ons for low-lift social proof
For brands already advertising on Reddit, the Conversation summary add-ons offer an easy win—especially for products that benefit from peer validation (think gaming, tech, automotive).
- Recalibrate for authenticity
Reddit’s bet is on "authenticity at scale." As AI-generated content floods other platforms, Reddit is positioning itself as the place where real voices still matter. That’s a brand safety angle worth noting.
- Don’t treat this as plug-and-play
While the tools promise automation, strategic input still matters. Context is everything on Reddit, and brands need to understand the culture of each subreddit to avoid tone-deaf placements.
Reddit is betting big that the future of advertising lies in community-driven insights—and it’s using AI to bridge the gap between raw conversation and campaign clarity.
For marketers, this is a chance to unlock relevance without guesswork.
