hello and welcome back to another fine edition of the Leaderboard. In today's issue, we're diving into an AI that handles all the messy terminal work, a calendar that says no to burnout, and a tool for creating slideshows on the fly.

Aider is an AI pair programmer that works directly in your terminal, letting you edit code inside your local git repository without bouncing between tools. It supports multiple large language models, including Claude 3.5 Sonnet, DeepSeek R1, and GPT-4o, and is designed to integrate seamlessly with your workflow.

🔥 Our take: Every developer has that moment where they’re deep in the terminal, staring at a problem, and thinking, someone else should deal with this. Aider is trying to be that someone. It’s not just another autocomplete—it actually works within your repo, making changes like a real coding partner. Whether that’s brilliant or slightly terrifying depends on how much you trust an AI to edit your files without making a mess.

Lifestack is an AI-powered calendar that syncs with your wearable devices to optimize your schedule based on your health data. It tracks things like circadian rhythms and stress levels to suggest when you should work, rest, or take a break, essentially acting as a personal assistant that actually cares if you’re exhausted.

🔥 Our take: Most calendars treat you like a robot. Tasks go in, deadlines come out, and whether you are actually functional is your problem. Lifestack flips that by factoring in how you feel, not just what you need to do. It is an interesting idea, but also a slippery slope. What happens when your calendar knows you better than you do. Next thing you know, it is canceling your 8 AM meetings because it knows you are lying to yourself.

TabType is a web app that turns your open browser tabs into clean, Notion-style slides, making product demos and presentations smoother. Instead of juggling windows or losing track of pages, it organizes your content into a structured, distraction-free format.

🔥 Our take: Live demos are a high-stakes game. One wrong click, and suddenly your audience is looking at your inbox instead of your product. TabType promises a cleaner, more polished way to present without the usual chaos. If it actually makes switching between tabs feel seamless instead of clunky, it could be a lifesaver for anyone who has ever fumbled through a presentation in real time.

Voice AI has made massive leaps, but there are still limits. Mati Staniszewski, CEO of ElevenLabs, is hosting an AMA to dig into what’s next. From lifelike speech synthesis to real-time AI-generated voices, he wants to hear what creators, developers, and founders wish they could do—but can’t yet.
