The Mostar Difference
Okara auto-publishes.
Mostar filters first.

Okara's paid plan posts automatically — no filter, no review, whatever the AI wrote.
Every Mostar output passes a 4-check Quality Gate before you even see it. Nothing ships until it's good.

🎯

Specificity

Every output must name your actual product and domain. Generic copy that could apply to any company gets flagged and regenerated.

⚡

Actionability

Vague "consider improving your SEO" advice is rejected. Every recommendation is concrete, specific, and executable today.

🎪

Relevance

Off-topic content that doesn't match your business category is caught before it reaches your queue. No wasted reads.

What Our Users Say

"This is exactly what a solo founder needs. I used to spend 6 hours a week on Reddit manually. Now I approve three drafts and move on."

Marcus T.
Founder, Loopline

"The GEO agent alone is worth the price. Seeing my product get cited in ChatGPT for the first time was genuinely shocking."

Sara K.
CEO, Stackwise

"I tried Okara. The quality was all over the place. Mostar's quality badge tells me immediately whether to use something or not. Night and day."

Dani R.
Indie Hacker

"Finally a tool that doesn't produce slop. The Writer Agent actually sounds like me. I've published 3 posts from it without editing a word."

James L.
Founder, Frontliner

"For a two-person team trying to get our first 1,000 users, this is a no-brainer. We can't afford a marketing hire. Mostar is the marketing hire."

Priya M.
Co-Founder, Tracebit

"The HN agent found a thread I would have never noticed. The draft it wrote got 40 upvotes and drove 200 signups in a day."

Tom W.
Builder

"$49/mo is an absolute steal. I was paying an SEO agency $2,000/mo and getting less. This is embarrassing for the agency."

Ehsan A.
Founder, 3nSofts

"The SEO audit found 23 broken links I didn't know about. Fixed them in an afternoon. Rankings improved in two weeks."

Nina B.
Solo Founder

"I've shipped 4 products that went nowhere because I couldn't figure out marketing. Mostar is the first tool that made distribution feel manageable."

Raj P.
Developer turned Founder

"The quality filter is a game changer. Other AI tools give you 90% garbage you have to sort through. Here you only see what's actually good."

Claire D.
Product Lead

"Set it up on a Friday. By Monday I had three quality Reddit drafts, a blog post outline, and my first GEO score. I was floored."

Ben F.
Founder, Fielder

"Bought the Founding User spot within 10 minutes of finding this. The $999 will pay for itself in the first month."

FAQ
Got questions?
You enter your website URL. Mostar reads your product, builds a 30-day marketing plan, and deploys 8 specialized agents that run around the clock across SEO, AI search visibility, Reddit, HN, X, LinkedIn, content, and email. Every output passes a Quality Gate before reaching you — so you only see drafts worth acting on.
Before any agent output reaches your dashboard, it's run through a 4-check quality filter: Specificity (does this mention your actual product?), Actionability (is there a concrete recommendation?), and Relevance (is this actually about your business category?). Content that fails is regenerated once. If it fails again, it's shown with a "Needs Review" flag so you decide. This is why Mostar outputs read like something a real human wrote — not like AI slop.
No — and that's deliberate. Okara auto-publishes on paid plans with no quality filter. We chose not to do that. Every Mostar output gets reviewed by the Quality Gate first, then you approve before anything goes live. Reddit and HN are always draft-only by design. Auto-execution is on the roadmap for v2, but only after quality is proven in production. We'd rather show you less and have it be right.
GEO stands for Generative Engine Optimization — your brand's visibility inside AI assistants like ChatGPT, Perplexity, Claude, and Gemini. The GEO agent runs a weekly scan, gives you a score from 0–100, and tells you exactly what content to publish to get cited more often in AI responses. Traditional SEO doesn't cover this. Mostar does.
The SEO audit and 30-day plan are ready within minutes of signup. Agent drafts start appearing in your queue within the first 24 hours. GEO score shows up after the first weekly scan. SEO ranking improvements from published content typically show in 2–6 weeks depending on your domain's authority.
Yes. Cancel from your account settings at any time. No questions asked. Your Founding User deal is a one-time purchase with lifetime access to the product — see the Founding User Terms for details on wind-down policy.
