As answered by people managing CodePen and Contractgenerator.io.
Contractgenerator.io's answer:
I was building another app and needed a custom contract. All the other options cost $200+ to use templates that didn't fit my needs. I ended up using ChatGPT to write the contract, but I still had to spend hours making sure it was perfect and filling out all the required information. On top of that, I had to pay for a separate e-signature platform, manually place signature fields, and guide the other party through the signing process—it took hours and wasn't worth the hassle. So I built Contract Generator to automate all of that. Now you can go from contract generation to signing in under 5 minutes, rather than spending hours on what should be a simple process.
Contractgenerator.io's answer:
While there are many contract generators on the market, what makes us unique is our AI-powered editing experience, similar to Cursor IDE. Simply tell the AI what changes you need, and it will edit the contract directly in real-time—no manual rewriting required. We also feature auto-filled tags that intelligently populate contract fields, saving significant time when preparing documents for signing. Combined with our streamlined workflow, this creates a superior user experience compared to any competitor on the market.
