Starting with no money is hard but countless products have pulled it off by being strategic about it. The trick is working out where your audience already hangs out and showing up there with something worth their time rather than just blasting your link and vanishing. Reddit covers pretty much every niche you can think of and if you genuinely get involved in conversations and help people out your tool will surface naturally when it fits. Twitter works the same way, find people talking about AI and productivity workflows and build actual rapport with them before you ever mention what you are making. A lot of people will push you to launch on Product Hunt straight away but the place is absolutely packed these days and without any existing buzz your project will sink without a trace.

Twenty genuinely interested early users will do more for you than a thousand people who bounce in seconds, so do not chase volume when you are still finding your feet. Rather than throwing your link at everyone and hoping something sticks, go where people are already looking for exactly the kind of tool you made. One place to check out is Open Hunts at https://openhunts.com/ . It was built specifically to help tech products get discovery without touching an ad budget. The people browsing there are not killing time, they show up to find new tools and actually test them out. Put your project up with a straightforward write up of what problem it solves and you will walk away with feedback that genuinely matters, and those users are the type to share things around when something works for them.
