Questions & Answers

As answered by people managing Zarek.tech and Diffyn.

What makes your product unique?

Zarek.tech's answer

Three things that actually differentiate it:

  1. It executes, not just advises. Most launch tools give you a checklist or a template. Zarek writes every piece of copy for every channel, verifies listings are live, and sends a daily briefing on what to do next. You don't leave with a plan — you leave with work done.

  2. It's channel-specific, not generic. A Product Hunt tagline sounds nothing like a Hacker News Show HN post, which sounds nothing like a Reddit r/SaaS post. Zarek writes for the venue, not for a generic "audience." That's the difference between copy that converts and copy that gets ignored.

  3. One URL in, full launch out. The input is just your product URL. Zarek figures out what you're building, who it's for, and what the right channels are — then builds the whole plan around that. No 40-question onboarding. No "fill in your target persona." Paste a URL, get a launch.


The honest one-liner: Zarek is the first AI that actually does the launch work instead of telling you what to do.

That's what separates it from every AI content tool and every launch checklist that came before it.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Why should a person choose your product over its competitors?

Zarek.tech's answer

The honest answer requires knowing who you consider competitors. But here's how I'd frame it against the three most likely comparisons:


vs. ChatGPT / Claude (DIY AI) You still have to know what to ask, what channels matter, what copy works where, and what to do first. Zarek removes all of that. It's not a smarter prompt — it's a system that already knows how launches work.

vs. Launch checklists (Notion templates, blog posts) They tell you what to do. Zarek does it. The copy is written. The channels are picked. The listings get verified. You don't manage a checklist — you review and approve finished work.

vs. Marketing agencies / freelancers Cost and speed. An agency charges thousands and takes weeks. Zarek starts the moment you paste your URL. No briefing calls, no back-and-forth, no invoice.


The real answer in one sentence:

Every alternative either makes you do the work yourself or costs serious money. Zarek is the only option that actually executes the launch alongside you — for free or close to it, starting in seconds.


That's the competitive positioning worth building into your landing page and any copy you write.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

Which are the primary technologies used for building your product?

Zarek.tech's answer

Frontend / UI-Lovable (AI app builder — what you're actively building with)

Backend / Database-Supabase (standard pair with Lovable — auth, database, edge functions)

AI-Large language model API (likely OpenAI or Anthropic) for roadmap generation and copy writing

Hosting-Lovable's built-in hosting / Vercel (common deployment target)

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

Zarek.tech's answer

Two layers to it:


Primary: First-time or early-stage founders People who just built something — a SaaS tool, an AI app, a side project — and now face the launch with no playbook. They're technical enough to build but not experienced enough to know which channels matter, what copy works, or what to do on day one. They've never launched before, or their last launch went nowhere and they don't know why.

Secondary: Solo product marketers and indie hackers People who've launched before but do it alone. They know what good looks like — they just don't have the time or budget to execute it properly. Zarek handles the execution so they can focus on the product.


What they have in common:

They have a working product with a URL They have no launch team They have limited budget (often zero) They need to move fast

They'll do the posting themselves — they just need everything written and sequenced for them

What they're not: Growth teams at funded startups. Those people have agencies, headcount, and budget. Zarek isn't for them — and trying to serve them dilutes the positioning.


That's the audience worth building every feature and every piece of copy around.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

Zarek.tech's answer

Zarek started with a failed launch.

I built a SaaS product and launched it the way most founders do — a Product Hunt post, a landing page, a vague plan to "post in some subreddits." The result was 11 upvotes, 3 signups (two were me testing), and a Reddit post removed in four minutes for self-promotion.

The embarrassing part: I work in product marketing. I knew what a good launch looked like. But knowing the theory and executing it alone — no team, no budget, no one checking your work — are completely different things.

After the post-mortem I realized the failures weren't about knowledge. They were execution gaps. Copy written at midnight. Wrong subreddits. Broken directory forms I didn't catch for weeks. No plan for day two or day five.

So I built Zarek to close that gap. You paste your product URL, it reads your site, understands what you built, and executes the launch alongside you — every piece of copy written for every channel, the right places to post with real pitches, every directory submission verified live, and a daily briefing so nothing falls through the cracks.

The name Zarek means "God has remembered." The idea is simple: your launch shouldn't be forgotten. And neither should any of the work that goes into it.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Who are some of the biggest customers of your product?

Zarek.tech's answer

Zarek is currently in early access. We're onboarding our first cohort of founders and collecting real launch data to improve the product.
