Stripe Atlas, Clerky, and others have some limitations you should check out first, like not having a lot of flexibility for different legal terms/conditions. It’s boilerplate.
You can also create your docs with CooleyGo for free, and then use a filing service like https://www.delawareinc.com. After that, you can get things like your Certificate of Good Standing (which you need for to file your California Qualification paperwork) directly on the delaware.gov website.

I filed multiple patents for my startup and we never used them. They took a lot of my engineering team’s time and were expensive to write, file, revise, and maintain. They never generated a penny in revenue.
I’ve only seen large companies defend and monetize patents, so if being acquired by an IP-focused company is in your exit strategy, they are worth considering, but I would be judicious with your time and money.
