Built a free toolkit that grew into 5 sites, 200+ tools, no signup required I started this a few days ago to build a free invoicing tool for freelancers because everything I found was gated behind a signup wall or a "free trial."

I built a tool to collaborate on HTML artifacts like a PowerPoint As a consultant, I've watched artifacts become more common as a way to communicate ideas and insights, both internally and with clients. The problem is there's no good way to comment on them, collaborate, or make quick edits; so in practice, they're slow to actually use. I built a free tool that lets you leave comments and edit directly, all while sharing with your team. After you make your edits you can export
