What StartKitz does

One URL. Your entire launch kit.

StartKitz analyzes your app URL and generates a complete marketing stack — growth report, competitor analysis, launch copy, social posts, Reddit drafts, video scripts, and rendered promo videos. All from one paste.

Everything you'd pay a copywriter for.

Social posts, Product Hunt copy, cold outreach, launch and welcome email sequences, ad creatives — packaged as a ZIP file ready to use. No brief. No back-and-forth. No blank page.

Built for founders who ship, not founders who write.

StartKitz is for indie hackers, SaaS founders, solo builders, and small teams who need marketing assets fast — so you can spend your time getting users, not writing about how you'll get them.

Generated in your founder's voice — from a real app URL

X / Twitter Post

Most founders I know are great at building. Terrible at talking about what they built. I was too. Spent three weeks on a launch post. It flopped. Then I pasted my URL into StartKitz and got a full kit in 60 seconds. First post got 40 signups. I'm not a marketer. I just stopped pretending I needed to be.

Product Hunt Hook

You don't have a marketing problem. You have a translation problem. Your app is good. You just can't explain it in a way that makes people stop scrolling. StartKitz reads your site and writes the copy your users actually respond to — in your voice, not ours.

Reddit Launch Draft

I've been building in public for six months and I want to be honest: the hardest part wasn't the code. It was finding the right words. I made StartKitz to solve exactly that. Paste your app URL, get your full marketing kit — posts, Reddit drafts, ad copy, video scripts — tuned to how you actually talk.

Frequently asked questions

What is StartKitz? +

StartKitz is an AI marketing tool that turns your app URL into a complete marketing kit. It analyzes your website and generates launch copy, social posts, Reddit drafts, competitor analysis, video scripts, and rendered promo videos — all from a single URL, in minutes.

Who should use StartKitz? +

StartKitz is built for indie hackers, SaaS founders, solo builders, and small product teams. It is designed for anyone who needs channel-specific marketing assets fast and does not want to start from a blank page every time they launch or promote an update.

What makes StartKitz different from ChatGPT? +

ChatGPT is a general-purpose assistant — you write the prompts and it writes text. StartKitz is focused on app marketing workflows. It starts from your landing page URL, understands your product automatically, and builds a Founder Voice profile from your site — so every asset reflects your actual tone, not generic AI copy. You get packaged outputs tuned to your voice, not a blank box.

Will the copy sound like me or like generic AI? +

StartKitz auto-detects your Founder Voice from your site — your tone, positioning, CTA style, and the words you actually use. You can review and adjust it before upgrading using the Founder Voice editor on your free preview page. When you generate your kit, every asset — tweets, Reddit drafts, Product Hunt copy, ad creatives — uses that voice. It won't sound like GPT defaults.

What kinds of products work best with StartKitz? +

StartKitz works best for SaaS products, web apps, mobile apps, AI tools, developer tools, and startup landing pages. Any publicly accessible product page with visible text about your product's features and audience will produce good results.

What do I get for free? +

You get a growth score (0–100), a scorecard with a one-line verdict on your biggest issue and a concrete fix, a one-liner and positioning tagline for your app, and a homepage hero rewrite showing your current headline versus the recommended replacement — with subheadline, CTA, and trust line. You also get 1 unlocked launch post (Twitter/X) and 1 customer pain point in customer voice. No sign-up required.

How long does generation take? +

The free preview takes about 15-30 seconds. Full kit generation (after payment) takes 1-2 minutes for text plans. Creator and Launch plans add video rendering, which takes an additional 30-60 seconds per video. Launch plan also generates a First Users Plan — a live search across Reddit and Hacker News that adds another 30-60 seconds on first load.

What is the First Users Plan? +

The First Users Plan is a Launch-plan feature that scans live discussions on Reddit and Hacker News in real time to find people actively describing a problem your app solves. It returns a ranked list of 3-5 threads with a confidence score, expected user range, and a ready-to-paste reply draft for each one.

What's in the ZIP download? +

The ZIP contains organized folders: report (growth report + competitor analysis), social (X posts, LinkedIn, hooks, CTAs, captions), reddit (post drafts + subreddit suggestions + Reddit Launch Kit on Launch plan), launch (Product Hunt, Hacker News, and App Store + Google Play listing files), videos (scripts + MP4s for Creator/Launch plans), and launch-extras (SEO report, launch email sequence, welcome email sequence, and cold outreach templates for Launch plan).

What format are the videos? +

Videos are simple vertical MP4 files (1080x1920) with bold text overlays, your app name, and URL — think clean slide-style content optimized for TikTok, Reels, and Shorts. Each video is 12-15 seconds and rendered once.

Can I edit the generated content? +

Absolutely. Everything is delivered as plain text files in the ZIP. Copy, edit, and post however you like. Reddit drafts include a reminder to humanize them before posting.

Do you support any URL? +

We support any publicly accessible URL. For best results, paste your marketing or landing page URL rather than your app's login screen or dashboard — we read the page's visible text, so content-rich pages produce better reports.

How many times can I regenerate my kit? +

Each plan includes a set number of regenerations — Starter (3), Creator (5), Launch (10). Regenerating refreshes all your marketing copy. Your growth report score stays fixed — it reflects your app's initial analysis and is intentionally kept consistent.

Is this a subscription? +

The marketing kits (Starter, Creator, Launch) are one-time purchases — pay once, keep your kit and ZIP download forever. The Opportunity Feed ($59/month) is the only subscription product — it delivers a live, ranked Reddit feed updated daily. You can cancel anytime.
