About these tools
Q1
Are these tools really free?
Yes. All nine are free with no signup and no usage limit. There is no paid tier on the tools themselves — they exist to be useful and to introduce the paid Shopify apps and Chrome extensions that go further.
Q2
Do they use AI or send my data anywhere?
None of them call an AI model or charge tokens. The calculators and the CSV, AI-detector, and Stocky tools run entirely in your browser and upload nothing. The audit, AI-shopping, checkout, and Merchant Center checkers fetch the one public page you name on our server, read it, and store nothing.
Q3
Which tool should I use?
For inventory and imports: the Stocky Converter, CSV Checker, Stockout Cost Calculator, and Days of Stock Calculator. For store health: the Store Audit, AI Shopping Checker, Checkout Checker, and Merchant Center Checker. For writing: the AI Detector.
Q4
Who builds these?
Vladislav Gerasimchuk, an indie developer in San Francisco. Each tool came from a problem he ran into while building the Extensions Market apps. Questions go to [email protected] and reach a real person.
