# Free SEO and AI search tools

> Every free Rankbox tool at /tools, what each one does, which ones use AI, the per-IP limit on AI runs, and how they relate to the paid product.

Rankbox has 23 free tools at [/tools](https://rankbox.xyz/tools) for making a site readable by AI engines, writing pages that get quoted, and checking whether AI recommends you. They need no account and no sign-up: open a tool and use it.

Use them for one-off jobs, such as writing an llms.txt file or checking a draft before you publish. The paid product does the same kind of work continuously for your site, as described at the end of this page.

## Three kinds of free tool

Every tool page carries a label that says how it runs.

| Label | How it runs | What leaves your browser |
| --- | --- | --- |
| **Instant** | Runs in your browser | Nothing. The crawler log analyzer, for example, never uploads your logs |
| **AI-powered** | Generated fresh by an AI model on each run | The text you enter, sent to Rankbox's server and its AI model provider |
| **Live check** | Fetches the URL you enter from Rankbox's server | The URL. Rankbox fetches the page, its robots.txt and its llms.txt |

AI-powered output is written by a model on each run, so two runs give different results and the output can contain mistakes. Check names, numbers and claims before you publish anything a tool wrote.

## Limits on the free tools

The six AI-powered tools share one limit: 6 runs a minute from the same IP address by default, across all AI tools together. Over the limit, a tool says **You've run a lot of these in the last minute. Wait a moment and try again.** The window resets each minute.

The **Live check** tool, AI Search Readiness Check, is limited per network on a much larger allowance and says **Too many checks from your network right now. Please wait a minute.** when it's exceeded. It only fetches public pages; private addresses and unsafe URLs are refused.

Instant tools have no limit because they never call Rankbox's server.

## All free tools by category

The [tools hub](https://rankbox.xyz/tools) groups the 23 tools into five categories. Every tool lives at `/tools/<slug>`.

## How the free tools relate to Rankbox

The free tools do single jobs by hand. Rankbox, the paid product, runs the whole pipeline for your site: it researches the questions your buyers ask, writes source-backed articles, scores them, and publishes them on a schedule. See [How Rankbox works](https://rankbox.xyz/docs/get-started/how-it-works.md).

- **Research.** The AI Question Generator and Content Brief Generator do by hand what Rankbox's research and writing do for every article. See [Research](https://rankbox.xyz/docs/content/research.md).
- **Scoring.** The AI Citation Readiness Checker and Heading Structure Checker check drafts one at a time; Rankbox scores every article it writes. See [The SEO and GEO score](https://rankbox.xyz/docs/content/scoring.md).
- **Inside your AI tools.** The [Rankbox MCP server](https://rankbox.xyz/docs/ai-tools/mcp-server.md) gives Claude, ChatGPT, Cursor and other AI tools three similar research tools: AI search questions, content briefs and meta descriptions.
- **Measuring AI visibility.** Rankbox doesn't track AI citations, so the AI Visibility Prompt Kit is the way to check by hand. See [How to measure GEO](https://rankbox.xyz/blog/how-to-measure-geo) for a method.

Nothing you type into a free tool is added to a Rankbox account, and the tools work the same whether or not you have one.
