Paid SEO suites like Ahrefs and Semrush cost $99 to $449 per month. For many content creators, freelancers, and small business owners, that budget doesn't exist. These free tools cover the most common on-page SEO checks without any cost, signup, or data collection.
The text tools run entirely in your browser, so your content never leaves your device, and they need no account. The one exception is the AI visibility checker: it sends only your domain to our server to run live web research, and the full report runs on a free account (no card) so the research budget stays protected. No usage fees, no credit systems.
