Github helps people manage software projects. SingularityHub helps people manage their consciousness and its offspring. Once you can upload your brain into a computer, you can copy it. You can change it. You can update it.
Your brain gets uploaded to our servers, and we track changes. If you fork (clone) it, and one of your copies learns something new, you can submit a pull request and one of you can accept it. Want to merge with someone? We got you covered.
As long as you are willing to share your brain with others, SingularityHub is and will always be free. And for the first 500 brains, private brain repositories are free (as in virtual beer) too!
