I keep building apps with Bolt.new, Lovable and V0, getting decent traffic from launches here, but then... crickets. People try it once and I never hear from them again. The problem isn't the apps - these tools are amazing for rapid prototyping. The problem is I have no way to stay in touch with people who seemed interested but didn't convert immediately.
I tried Mailchimp and ConvertKit, but integrating them into my fast iteration cycle was a pain. Plus they're overkill for simple "hey, I fixed that bug you mentioned" updates.
What I built
So I made Writaia - basically email capture designed for indie makers who build with Vibe Coding tools. The integration is stupidly simple: click "Copy for AI" in the dashboard, paste it into Bolt.new/V0/Lovable chat, and you're done. Takes maybe 30 seconds.
Then when you want to email your users (like when you ship that feature someone requested), you just type what you want to say and it helps you write a proper email. No templates, no complex automation - just "turn my casual update into something professional."
Why it's working
I've been using it on my own projects for a few months. What I noticed:
People actually do want updates, they just forget to check back
A simple "hey, remember that app you tried? I fixed the loading issue" gets surprising engagement Having email addresses makes you feel more accountable to actually improve the app
It's not revolutionary, but it solves my specific problem: staying connected with people without becoming a marketing person.
Questions for HN
Do you have this same problem with your side projects?
How do you currently handle user communication?
Other Vibe Coding tools I should support?
Happy to answer questions about the technical implementation too. The "Copy for AI" approach was trickier than expected - had to figure out how to generate platform-specific code on the fly.
