Have a legal problem? Ask a robot. Helper bots are poised to do much more than order you a pizza.

Joshua Browder’s quest to help ordinary people navigate legal systems started because he was bad at parking. He knew how to program apps, so after successfully conquering the parking ticket system in his native London last year, he developed a simple chatbot that could walk his friends through the same process.

After appealing over 175,000 tickets and expanding to help the homeless, his chatbot marked the accidental beginning of a movement that Browder now leads: creating bots to help average citizens untangle legal systems.
