In most small businesses there is a set of procedures that exist entirely in somebody's head. How the month-end reconciliation is done. What order the machine is shut down in. What has to be checked before a job is signed off. How a new customer is set up in the system. Everyone agrees these should be written down. Almost nobody writes them down, and it is worth being honest about why: not because there is no time, since each would take twenty minutes, but because writing instructions for something you do automatically is genuinely difficult. The steps you perform without thinking are the steps you forget to mention, and they are usually the ones that matter.
This is a good use for a conversational tool, and the effective method is the reverse of what people expect. Rather than asking it to write a procedure - which produces a generic one that describes nobody's actual process - describe what you do, roughly, in whatever order it comes out, and let it ask the questions. It will ask what happens if the file is not there, what you do when the figure does not match, who is told when it is finished, what the thing is called that you referred to as the usual place. Those questions are the value. They are the gaps a reader would fall into, and they are invisible to the person who has done the task two hundred times.
The output then needs one thing that no tool can supply, which is a test. Give the written procedure to somebody who has not done the task and watch them try to follow it without helping. They will stop at the third step, and where they stop is the real defect. This is uncomfortable and it takes twenty minutes, and it is the difference between a document that exists and a document that works. A procedure that has never been followed by anybody other than its author is a draft, however tidy it looks.
The reason to do this at all is not tidiness. It is that these procedures are exactly what a business cannot do when the person who holds them is ill, on holiday, or has left - and it is what makes it possible to hand a task to somebody else, which is the only way anything ever gets off the owner's list. The tool does not make the writing valuable; what it removes is the specific obstacle that has been stopping it, which is sitting in front of a blank page trying to remember the steps of something you no longer consciously perform.
