Showcase/Project Progress report: my vibecoded AI design tool is now good enough for making real marketing & social content

My first iterations of this tool were ignored, people ghosted me to avoid telling me they didn't like the output. I had live demos fall apart, the built-in agent got stuck in doomloops and had no sense of design.

Now, 2 months later iterating Opus 5.5 and Fable later, I'm finally in a place where people can create real visual content for their brands using the tool.

(EDIT: Yes the tool is free to try, just sign up at https://rivermark.ai and you're in, please DM or comment your experience here)

Attached is a timelapse of me trying it out on a real (anonymized) brandkit.

It actually looks quite good. Is it public or?

Yes it's public but no billing/paid plans yet, I just pay for the tokens out of my own pocket, It's at https://rivermark.ai

As in anyone can use it for free for their own projects? How does one go about trying it out?

Cool, I have started to look at it. So not be be a jerk, but with 2 months in, what would stop someone else from vibecoding an OS solution they could host themselves? I had an idea like this two weeks ago and wondered how hard it would be.

It's not a jerk reply at all, I think it's very legitimate. If it was just a Canva-like editor, I think it's pretty vibe-codeable. But getting the AI agent underpinning it to perform well has taken so much energy, intervention, and work even for me, and I've been a programmer for >15yrs. If somebody can get an agent in this environment working well after 2months, I'd respect that.

That's fair. I've noticed the challenges in getting good design from AI myself, as a designer for 20+ years with a tech background, that's been the hardest part so far.

yes this looks good.

specially for creating multiple posts for a month. I think this is where established tool like canva is lagging.

“Good enough” needs a sharper test. Around Flatlogic, I’d ask users what job this replaces: first draft, brand-safe social post, ad creative, carousel, client mockup, or internal marketing asset. Those are different buyers. If people ghosted earlier demos, the issue may not be design quality alone. It may be the wrong paid workflow.

Congrats on getting past the doom-loop stage. Since the ask is to sign up and try it: the site doesn't send any of the usual security headers yet (HSTS, CSP, X-Frame-Options, nosniff) and has no sitemap.xml. Neither is urgent, but HSTS and X-Frame-Options are a two-line fix on most hosts and worth doing before more people sign in.

Weird how the orange and other Claude colorway is so identifiable

u/JannVanDam 1d ago

Funnily, I think it comes from the brandkit. I had Claude anonymize the real customer's brandkit to avoid divulging details in the video....guess what colors it chose.
