Overview

<p><b>Startup description</b></p><p>My startup is a Chrome extension that turns rough ideas into expert-level prompts in one click. Works across ChatGPT, Claude, Gemini, and every AI tool - users write a messy idea, hit the Sloth button, and get a structured, context-rich prompt back.</p><p>I started it in May 2025 as a side project after getting tired of rewriting the same prompts over and over. Shipped it to the Chrome Store and grew from there - initial traffic came from submitting to free AI directories, and a handful of content creators have organically mentioned the tool on YouTube and TikTok since. I'm selling because I'm heads-down on my main product and this one deserves an owner who can actually work the growth channels.</p><p><b>Key highlights</b></p><ul> <li>5,000+ active Chrome Store installs, growing organically</li> <li>3,000+ emails captured in the database</li> <li>~$1,746 all-time revenue, ~$1,285 last 30 days (Stripe-verified)</li> <li>28 active paid subscriptions + ongoing Lifetime deal sales</li> <li>Pricing: Free / Pro $4.99/mo / Lifetime $89 one-time</li> <li>~95% net margin (hosting + API costs are minimal)</li> <li>Content creators have already mentioned the tool organically on YouTube and TikTok + SEO</li> <li>Total marketing spend to date: $50 (one listing on There's An AI For That)</li> </ul> <p><b>Marketing and growth</b></p><p>I do almost no active marketing. All growth came from:</p><ul> <li>Free AI directory submissions - this is where initial traffic came from. Submitted to a bunch of free directories, and they still drive steady installs</li> <li>There's An AI For That, paid $50 once for a listing. That's the only money spent on marketing, ever</li> <li>Chrome Web Store organic search - extension ranks for prompt-related keywords</li> <li>Organic creator mentions - a few content creators have mentioned my tool on YouTube without any outreach from me.</li> </ul> <p><b>Untapped channels any buyer can run tomorrow:</b></p><ul> <li>Influencer outreach - proactively reaching out to AI creators (cheap in many markets) is the obvious first move</li> <li>Short-form content (TikTok/Reels/Shorts)</li> <li>Email list activation - 3,000+ emails have never been marketed to.</li> <li>Paid ads on Meta/Google - with a $89 Lifetime product and proven organic conversion, this should be profitable</li> <li>More directory/listing coverage - there are plenty of AI directories I haven't submitted to yet</li> </ul> <p><b>Revenue and profit</b></p><ul> <li>All-time revenue: $1,746 (Stripe-verified)</li> <li>Last 30 days revenue: ~$1,285 (mix of Pro subs + Lifetime deals)</li> <li>Recurring MRR: ~$135 from 28 active subs (Lifetime sales add meaningfully on top)</li> <li>Monthly costs: ~$20–40 (Supabase, domain, hosting, OpenAI API)</li> <li>Total marketing spend to date: $50 (one-time)</li> <li>Net margin: ~95%</li> <li>CAC: Effectively $0 - all acquisition is organic</li> <li>Churn: Low; Pro price point ($4.99) is painless and most churn is Pro → Lifetime upgrades</li> </ul> <p><b>Startup assets</b></p><ul> <li>Chrome Web Store listing with 5,000+ installs (the real moat — store ranking and install momentum can't be bought)</li> <li>.com domain + full codebase</li> <li>Supabase database with 3,000+ registered users</li> <li>Stripe account data (transferred per Stripe) + 28 active subs</li> <li>Full codebase: extension + landing page + dashboard, documented</li> <li>Directory placements - existing listings across AI directories including There's An AI For That</li> <li>Brand assets: logo, illustrations, copy</li> <li>30-day founder handover - tech transfer, Chrome Store ownership, walkthroughs</li> </ul> <p><b>Summary</b></p><p>You're buying a 5,000-install Chrome extension with 3,000+ untapped emails, Stripe-verified revenue, a 95% margin, and a product that creators already mention organically - built on a total marketing spend of $50.</p><p>The $135 MRR number undersells what's here. The real value:</p><ul> <li>A ranked Chrome Store listing in the AI category (nearly impossible to replicate)</li> <li>5,000 installed AI power users + 3,000+ emails never marketed to</li> <li>A working funnel (Free → Pro → Lifetime) converting with zero optimization</li> <li>Organic eyeballs, zero effort getting users</li> <li>Near-zero operating cost - profit flows straight through</li> </ul> <p>I'm selling because I can't give it the time. For an operator with 5 hours/week who runs even a basic email sequence and some creator outreach, $1–3k MRR within a quarter is realistic.</p><p>✅ $1,440 in Annual revenue</p><p>✅ 28 customers</p><p>✅ Business model: SaaS+LTD</p><p>✅ Built with Next.js, Supabase</p>

Annual Revenue

Number of Customers

Expenses

$10 domain; $20 database.

Business Model

Freemium SaaS Chrome extension. Free tier with limited usage, Pro subscription at $4.99/month, and a one-time Lifetime deal at $89. Revenue comes from Pro subscriptions (28 active) and Lifetime deal purchases. ~95% net margin with minimal costs ($20–40/month for Supabase, domain, hosting, and OpenAI API).

Target Audience

AI power users, content creators, marketers, developers, and anyone who regularly uses AI tools like ChatGPT, Claude, and Gemini and wants to write better prompts faster.

Asking Price Reasoning

The price reflects a ranked Chrome Store listing with 5,000+ installs (near impossible to replicate), 3,000+ emails never marketed to, verified Stripe revenue (~$1,285 last 30 days), 28 active paid subs, ~95% margin, and near-zero operating costs. For an active operator, this is a significantly underpriced asset with clear, untapped growth levers.

Reason for Selling

I'm heads-down on my main product and can't give it the time it deserves. The tool has great organic traction and a clear growth path — it just needs an owner who can actually work the channels. I'd rather sell to someone who can take it further than let it grow slowly on autopilot.

Growth Opportunity

Massive untapped growth potential: 3,000+ emails never marketed to, influencer/creator outreach in the AI niche, short-form content (TikTok/Reels/Shorts), paid ads on Meta/Google (proven $89 Lifetime product with organic conversion), and more AI directory submissions. With 5 hours/week and a basic email sequence, $1–3k MRR within a quarter is realistic.

30 days free support from seller

Competitors

PromptPerfect, AIPRM, FlowGPT, and other AI prompt tools and Chrome extensions — but none match the organic Chrome Store ranking and install momentum my product has built with near-zero marketing spend.

Tech Stack

Next.js, Supabase.
