AI is talking behind your back

gm friends! Welcome to the final issue of the Leaderboard for this week! We're taking a quick look at OpenAI's latest voice models, a tool that generates highlights from your conversations, and AI agents that have started to talk to each other...behind our backs 😨

OpenAI’s new GPT-4o audio models let you build voice agents that actually sound like people. Real-time speech, emotional tone, and multi-language support, all faster and more natural than before.

🔥 Our take: Most voice AI still sounds like it’s reading off a cue card. GPT-4o is different. It’s fast, weirdly human, and just expressive enough to make your app sound like it has feelings. Great for building assistants—potentially cursed if your to-do list starts sounding disappointed.

The Product Hunt community never holds back, and we love it. In our recent forum post on roasting landing pages, we noticed Praveen Chary with sitelifter delivering some A+ critiques - brutal, but fair. Check out the thread for some spicy takes and useful insights on what makes (or breaks) a great landing page!

Got a landing page in need of some tough love? Drop it in the thread and brace yourself.

Strella Insights 2.0 helps you instantly search, summarize, and clip key moments from interviews and conversations. With smarter search, shareable highlights, and a chat-style explorer for your research repository, it’s built to make digging through raw footage a thing of the past.

🔥 Our take: User research is valuable, but let’s be honest, most of it dies in a Google Drive folder no one wants to open. Strella makes it way harder to ignore. It turns hours of calls into bite-sized, usable proof you can actually show to your team. Whether that leads to better decisions or just stronger opinions backed by timestamps, at least the receipts are ready.

Multi-Agent Builder by Credal lets enterprises deploy secure, collaborative AI agents that can communicate, coordinate, and take action across tools. Agents can trigger one another, access internal data, and handle complex tasks—without breaking permission boundaries.

🔥 Our take: We’ve officially entered the era of agents managing other agents. Multi-Agent Builder turns the dream of autonomous workflows into something less sci-fi and more "oh, this might actually work." Whether it's efficient or just the beginning of bots forming committees, it's a bold move toward AI doing more than just answering prompts.
