I'm in Situationship with My Startup
I love building product as soon as I stumble upon an interesting idea.
My idea was to come up with icebreakers based on person's profile. I built this tool: getdatahawk.ai without any customer calls
I have around 150 users, none paying & almost no daily active users. 2/150 people agreed to jump on customer call.
I am wondering if this is a big enough problem for people to care about or should I move on. How do I decide?

Ask HN: What have you recently failed at?
I am building an app to fight propaganda online. Need your help
So long story short I was recently bombarded with an insane amounts of right-wing propaganda online and Russian bots so I decided I can somehow simplify the validation of the facts that are posted by people online.
I have made a research of tools that are currently available for that and I've found that ChatGpt is quite biased with some topics and it lacks data about latest issues even when search mode is enabled. At least it takes some time for it to update it's memory or something
Then I've checked a Google Fact Check tools which were even worse. Bad UI... I had no idea how it validates things because usually proof links that Google provides are quite random.
So I decided to build a tool that simplifies the research. The idea was simple - you have a claim - you paste it in app and it goes on web collects articles on topic then processes them with ai and makes a decision based on those articles.
The app is running right now. It is completely free and no ads. Also it generates a small article where it tells about how it made a conclusion.
The link to app is: https://truthorfake.com/
Also I need your help - How can I make this app better? Also feel free to test your claims so that I can have more real data to tune this app on.
I believe that this is something that is necessary for all of us especially in those crazy times!
Thanks for reading this!
