Do more with what you have. Pay for less.

For years, every new problem came with a new subscription: one app for design, another for websites, another for automation, another for notes. AI has changed that. A general-purpose assistant, an office suite and a little know-how can now do many jobs that used to need a dedicated product.

But not all of them, and not equally well. Some teams genuinely need the collaboration, governance or precision of the specialist tool. Switching for the sake of it can cost more than it saves.

OneLessTool exists to tell the difference. We map what software actually does, capability by capability and plan by plan; check what you already own; show you how to do the job with it; and give you a checklist to prove it works before you cancel anything. Sometimes the best recommendation is to buy nothing. Sometimes it's to keep paying. We'll tell you which.

For people and for agents

More and more software decisions start with a question to an AI assistant. So everything here is also available as structured data — an API, an MCP server and plain-text files — so those assistants can give answers with sources instead of guesses.
