Publish and ask

Make it findable and shareable

Check the page title, the description and the preview image that appears when the link is pasted into a message. Add a short line at the bottom: who made it, and a link to send feedback, even if it is only an email address.

Send it to five people, personally

Not a post into the void: five messages to five people who have the problem. Say why you thought of them, include the link, and ask one question:

“What stopped this from being immediately useful?”

It invites honest answers and points straight at the next fix. “Looks great!” is pleasant and useless; “I did not know what to paste” is gold.

Write the answers down

In the same note as your not-list. After a week, you will see whether people come back, whether they ask for the same thing, and whether the tool deserves a second weekend.

Then decide

Three outcomes are all good:

• Nobody needs it. You learned that in 48 hours instead of six months. Leave it online; it costs nothing.
• A few people use it. Fix what they say, once.
• People ask to pay for more. That is the start of a product.

Done when

The tool is on its final address with a feedback link, five people have it, and their answers are written down. You finished something. Next time will be faster.
