Turned ChatGPT, Claude, and Gemini into project management apps, and one clear winner emerged

Turning ChatGPT, Claude, and Gemini into project management apps centers on an experiment showing how large language models can be reshaped beyond chat. The creator used ChatGPT in 2024 after it introduced Memory, combining it with a system prompt to store tasks, retrieve them with a command (“Start PMS”), and use scheduled tasks for daily summaries of what remained. The main limitation was that all tracking lived inside a chat window, leaving tasks as text rather than a dedicated UI. He then expanded the approach after Claude arrived, aiming to better replicate real project-management workflows. The article frames the winner as the model that most cleanly delivered a usable interface and practical task handling, based on side-by-side testing of ChatGPT, Claude, and Gemini.
