AI is transforming the legal industry and CORTO is at the forefront of this change. There is a huge opportunity for law firms to save time, money and to add more value to their client base. This is where AI Paralegal comes in. AI Paralegal is a startup transforming the way legal work is done to unlock new value for law firms and their clients. We will be utilising our in-house expertise and the power of AI to save hours of work and transform the way law firms provide access to legal justice.
