After getting 30 parking tickets while in London, a 19-year-old Stanford University student created an app called DoNotPay that lets people fight tickets by chatting with a bot.

From The Guardian:

The program first works out whether an appeal is possible through a series of simple questions, such as were there clearly visible parking signs, and then guides users through the appeals process. The results speak for themselves. In the 21 months since the free service was launched in London and now New York, [Joshua] Browder says DoNotPay has taken on 250,000 cases and won 160,000, giving it a success rate of 64% appealing over $4m of parking tickets.

Browder is working on three other applications of his chatbot lawyer: one that helps people get compensated for flight delays, another that helps people with HIV positive exercise their rights, and another that helps refugees deal with foreign legal systems.
