This is how the toolkit works

One URL in, a useful answer saved

Standalone tool sites answer a question and then forget they exist. The toolkit sits in your workspace, so every review starts faster and ends in a useful place.

Choose the result

Browse the 36 tools by task or filter by category: Exams, Analyzers, Generators, AI and SERP, Writing and Monitors. Recently used tools remain just a click away.

Run it in seconds

Insert a URL, a text block or a log excerpt. Live checks retrieve the real page, take into account the website's robots.txt, and can identify as Googlebot, GPTBot, or a phone if the question requires it.

Preserve the evidence

The results are saved privately in your workspace and can be reopened later. If a review uncovers a real issue, a full site audit is just a click away and context is carried along.

Questions about the toolkit

The details, answered directly

Usage patterns and worked examples live in Guide to Tools and Studios.

Are the tools really free?

For areas marked “Free,” the free workspace is included in every plan. Log in and run as often as your work requires. Only the AI and live tools SERP consume credits, and this is also displayed before execution.

What does “use credits” mean?

Tools that paid providers call, such as the AI Visibility Checker, the Rank Checker, the Writer and the Paraphraser, are measured. Usage is visible in your workspace and limited by monthly caps per plan, so a busy afternoon is never a surprise.

Do my results disappear when I close the tab?

No. The results are saved privately in your workspace. Your most recently used tools remain pinned to the top of the toolkit, and you can reopen, review, or remove a saved result later.

Can I run exams as Googlebot or GPTBot?

Yes. The page checker, redirect checker and header checker have a “check as” selector with search bots, AI bots and a phone profile, and the robots.txt tester covers more than twenty crawler user agents. Cloaking and bot-specific behavior have no reason to hide.

Do I need to add a site before using the tools?

No. Each tool runs on any public URL or inserted input. By adding a site, the tool results can be easily linked to that site's audits, collecting the evidence in one place.

Are there any usage restrictions for the free tools?

Fair usage rate caps protect shared infrastructure and are never affected by normal professional use. The credit-backed tools are instead limited by your plan's monthly limits.
