OpenAI released ChatGPT for Excel in March. It runs inside Excel as an add-in. You type a prompt, and it builds a sheet. Just type the prompt and get the result. Microsoft shipped a Project Manager Agent inside Planner in January. Google has Gemini inside Sheets doing the same kind of work.
A project manager can now describe a project to an AI and get a working Gantt chart in under a minute. The AI picks the formulas, sets the conditional formatting, and hands back a sheet the team can share. No software license. No onboarding.
The project management software industry, valued at around $8 to $11 billion in 2026 depending on which research firm you ask, is suddenly competing with a prompt.
What’s actually happening
The gap between “I need a project tracker” and “I have a project tracker” used to be filled by a SaaS onboarding flow. Sign up, invite the team, configure the workspace, learn the tool. It took hours and a monthly subscription per seat.
That gap is now filled by a sentence. Type the sentence into ChatGPT or Copilot. Get a sheet. If the sheet needs a Gantt view, the conditional formatting trick that turns a spreadsheet into a Gantt chart takes two formulas and ten minutes. The AI writes the formulas. The team starts the project.
The numbers from the incumbents tell the story
Asana stock is down about 50% in 2026, on top of 32% in 2025. Its net retention sits at 96%, which means existing customers are shrinking rather than expanding. The CEO stepped aside. Analysts downgraded the stock in December 2025, citing weak product signals and persistent churn.
Monday.com, ClickUp, and Smartsheet face similar pressure. Smartsheet at least has the right shape for this moment, because it’s already a spreadsheet pretending to be PM software. The pure-play task management companies have a harder road.
Why AI is different from the last threat
The PM software category has survived competition before. Free tiers from bigger platforms. Open source alternatives. Microsoft bundling Project into Office. None of those threats actually killed the category. They just compressed its margins.
AI is different because it collapses the build step entirely. Previously, even with a free tool, a team still had to configure it. With AI inside Excel or Google Sheets, the configuration step disappears. Type what you want. The sheet appears.
When the build step takes two minutes and costs nothing, the economics of paying $15 to $30 per seat per month for a specialized tool stop making sense for any team that isn’t already deeply embedded in one.
What the incumbents are doing about it
Building their own AI. Asana launched AI Studio, which grew sequential ARR more than 50% in Q4. Microsoft has Copilot. Atlassian acquired DX for $1 billion to bolster its AI story. Every PM vendor has an AI strategy deck.
The problem is that none of these AI features fix the core issue, which is that AI outside the PM tool is getting just as good as AI inside it, and AI outside is free with most ChatGPT or Microsoft 365 plans. The moat was never the AI. The moat was the friction of setting up a project plan, and that friction is gone.
The tool that survives this is the one users already have
Spreadsheets were always capable of running projects. The PM software industry existed because building a project plan in a spreadsheet took skill and time. AI removes both requirements.
Microsoft knows this. It’s why Copilot for Excel is positioned as a project planning assistant, not just a formula helper. Google knows it too. The AI inside Sheets is pushing users toward structured templates for the same reason.
The specialized project management SaaS tool was a product of a specific era. That era is closing. The tool that wins the next one is the one that was already on every computer.
It will be interesting to see which companies build their AI strategy around that, and which keep trying to be standalone platforms.
