There was no unified tool for handling repetitive tasks and ensuring access to information across the company. Employees spent too much time on routine activities such as writing meeting notes and searching for information. Security concerns had previously discouraged the client from using AI tools. Off-the-shelf AI solutions were unsuitable due to per-user fees and high costs.
