Spine AI

Spine AI (YC S23) We’re building Spine because thinking deeply still matters and research isn’t a task you complete once. Research is an ongoing process of noticing, questioning, connecting dots, and sharpening judgment. Most tools treat research like search: transactional, shallow, disposable. But serious work needs something different. Something structured enough to scale, flexible enough to evolve, and smart enough to stay out of the way. Spine uses AI to support the way people already think, not to replace it. We automate the grunt work, help you map ideas as they grow, and make it easier to get from messy input to clear insight. This is how better decisions get made. Not by shortcutting the process, but by giving people better tools to do it well.
