Frequently asked questions

Is this tool free?

Yes — completely free, no signup, no watermark and no limits. Startup OG funds the site through its directory and partner program, not paywalled tools.

What is the difference between camelCase, snake_case and kebab-case?

camelCase joins words with capitals (`myVariable`), snake_case uses underscores (`my_variable`), kebab-case uses hyphens (`my-variable`) and is common in URLs and CSS.

When should I use Title Case vs Sentence case?

Title Case ("Build Your Startup") suits headings and product names; Sentence case ("Build your startup") is friendlier for UI text and modern brand voice.
