Legalicity is a legal technology startup based in Toronto.

We are lawyers, scientists, and engineers who have deep expertise in both Artificial Intelligence and law.

Our mission is to build great products that save you time and money and help you work smarter.

We are creating the next generation of patent tools.

NLPatent is a new online tool that uses Artificial Intelligence to reduce the uncertainty involved in applying for a patent.

Patents are valuable business assets. They can be a great way to protect what you've created. But getting a patent is very costly and time-consuming. We use state-of-the-art Machine Learning and Natural Language Processing (NLP) techniques to evaluate the patentability of new ideas. This helps companies and inventors decide whether an invention is worth pursuing.

We write about our startup journey.

We've launched a new publication, Legalicity Buzz (, where we highlight and comment on important developments in the world of legal technology, intellectual property, Artificial Intelligence, and entrepreneurship in general.

We share our insights and experiences as we continue to grow and innovate.
