Happy Tuesday and welcome back to the Leaderboard, the newsletter that helps you find your next favorite product. In today's issue: a therapy device that uses music, an AI-powered coding sidekick, a tool for speeding up those pesky PR reviews, and a two-for-one on AMAs from Supabase and Wordware.

Midlife Engineering is an interactive synth that turns sound therapy into something you can play with. Instead of passive listening, you create ambient soundscapes to help with focus, stress relief, or just zoning out in style. It’s like a meditation app, but with knobs.

🔥 Our Take: There’s something weirdly satisfying about tweaking sounds until they feel just right. Turning that into a tool for focus and stress relief makes a lot of sense—especially for anyone who finds guided meditation a little too structured. Whether it actually helps or just gives you an excuse to play with synths, it’s a cool way to tune out and reset.

Zeta is an open-source model from Zed that predicts your next code edit, aiming to make coding more fluid and reduce interruptions. Instead of just suggesting snippets like an autocomplete tool, it anticipates what you’re about to change and offers smart inline edits. It’s designed to blend seamlessly into your workflow, making the coding process feel faster and more natural.

🔥 Our Take: Code editors have been racing to get smarter, but most AI tools still feel like assistants rather than true collaborators. Zeta takes a different approach, predicting changes rather than just filling in blanks. If it actually gets good at anticipating edits without getting in the way, it could make coding feel a little less like typing and a little more like thinking.

Pull Sense is an AI-powered tool that automates pull request reviews on GitHub. It provides AI-generated feedback to identify potential bugs, security issues, and areas for code improvement. Designed to enhance, not replace, human reviews, Pull Sense supports a "Bring Your Own Key" (BYOK) model, allowing developers to maintain control over their AI integrations.

🔥 Our take: Reviewing pull requests is one of those necessary evils—important, but not exactly the highlight of anyone’s day. Pull Sense promises to make that process smoother by flagging issues before you even get to them. If it actually helps cut down on nitpicky back-and-forth while keeping quality high, it could make PR reviews a little less painful.

We've got a two-for-one AMA today with the founders of Supabase and Wordware.

Supabase CEO Paul Copplestone will be diving into everything about building and scaling an open-source software company, while the Wordware team shares their strategies for launching successfully—both on Forums and X Spaces.
