Full circle: Perplexity started as a slackbot prototype in 2022 and we’re making our way back into multiplayer enterprise use cases: prototyping in public shared channels, sharing knowledge with AI, and responding to feedback in realtime by converting Linear tickets into code.

We are also bringing Computer to Slack. When we first tested Computer internally, it was as a Slack integration. We found it was a powerful way to share and collaborate on tasks. Now you can add Computer to any channel or DM.

Perplexity Computer replaced $225K/yr in marketing tools in a single weekend. We built an AI marketing agent that scans hourly, manages budgets, detects fatigue, and coordinates several campaigns end to end. In one test run, it made 224 micro-optimizations to our ad stack.

Computer works for you on your hardest tasks. Available on web and for Max users today - mobile and pro users coming soon! Kudos to the team: building a new product from scratch in such a short amount of time wouldn't have been possible without Computer itself and the rapid pace of AI acceleration.

Jeremy Fineman presents his breakthrough algorithm at the ICPC 2025 World Finals in Baku: the first algorithm for single-source shortest paths with arbitrary negative weights (real, not integer) to improve upon Bellman-Ford from the 1950s: O~(m n^{8/9}) running time.

@Barry59700119 @jeffgrimes9 The stock ticker is GS-PC, not GS, so the P/E ratio is lower because preferred shares function differently from normal shares. But I agree that we should omit it since preferred shares are likely not what people are looking for when searching for companies.

@jeffgrimes9 If a summer intern at Goldman came up with a screen showing Goldman at 1.7x P/E, they would be fired on the spot for lack of attention to detail

Stock screening is now available as a separate tool at perplexity.ai/finance?tab=sc…, but we will be integrating everything into Perplexity's core engine very soon, bridging the gap between quantitative and qualitative answer engines.
