Expenses

LLM (OpenAI/Gemini): $3; VPS: $4; Domain: $10/year.

Business Model

Starter: $14 / month — ideal for light / small form-filling needs. Premium: $39 / month — includes up to 1,000 fill requests and advanced features for handling complex forms. Expert: $89 / month — includes up to 3,000 fill requests and full advanced form.

Target Audience

Small business owners or e-commerce sellers who need to fill product listings across multiple marketplaces. Job seekers or professionals applying repeatedly to jobs and needing to avoid repetitive data entry. Startup founders or operators.

Asking Price Reasoning

The $2,000 asking price is justified based on the combination of recurring revenue, paying users, proven demand, and extremely low expenses.

Reason for Selling

I am selling this project because I am currently focused on larger AI SaaS projects and no longer have the time to maintain and grow this product.

Growth Opportunity

Broaden into agency and enterprise pricing: enable membership plans, multi-user accounts, and bulk form-fill workflows for companies. Expand integrations with major e-commerce platforms (e.g., Shopify, Amazon, Etsy), job-boards and investor networks.

30 days free support from seller

Competitors

Generic browser-extension form-fillers (e.g., autofill tools) — though they lack AI-powered detection and reuse across forms. Workflow automation platforms (e.g., Zapier, Integromat) when configured for form-submissions.

Tech Stack

Node.js, Angular, HTML.
