3 heavy-duty tools · Free to use

Advanced SEO tools

For when paste-and-go isn't enough — AI query clustering, an indexing pipeline you can watch at work, and full domain portfolio management.

The advanced tools

Semantic Query Grouper

Paste or upload thousands of search queries and let AI cluster them into intent-based groups you can actually build pages around. The clustering runs on your own AI account — no credits or caps from us — and every group exports as tidy CSV.

You'll need: a free Gemini or Mistral API key — the tool shows you where to get one.

Keywords & contentBYO AI key

FatCat Annotator Pipeline Visualizer

An interactive, in-browser simulation of a Google-style annotator pipeline: HTML structural weighting, Knowledge Graph entity alignment, sparse hashing and dense vector embeddings with cosine similarity. Paste HTML and watch each stage transform it.

You'll need: nothing — it runs entirely offline in your browser.

Domain Manager

Track every domain you own in one place: expiry dates, renewal and purchase prices in INR & USD, sales and registrars — with reminders, bulk import and auto WHOIS lookup. Built for portfolios, not single domains.

You'll need: a free account, so your domain list is saved to you and available on any device.

What makes these advanced

AI on your own key

The Query Grouper calls Gemini or Mistral with a key you own. Your quota, your data relationship with the provider — no middleman credits to buy.

See inside indexing

The FatCat visualizer turns abstract ranking talk into something you can watch: structural weighting, entity alignment, hashing, embeddings.

Portfolio-grade domain ops

Domain Manager treats domains like the asset sheet they are: costs, renewals, sales and registrars, with reminders before anything lapses.

Still free

Advanced doesn't mean paid. All three tools are free to use — the only accounts involved are your own AI provider key or your Domain Manager login.

Pins work here too

Pin any of these cards and the tool appears in the Pinned row on the main SEO Tools page — one launcher for your whole kit.

How it works

  1. 1

    Pick the job

    Clustering keywords, understanding indexing, or running a domain portfolio — each tool here owns one deep job.

  2. 2

    Bring what it needs

    A free AI key for the Query Grouper, a free account for Domain Manager, nothing at all for the FatCat visualizer.

  3. 3

    Go deep

    These tools reward a little reading — each tool's page explains its options, limits and exports right below the tool itself.

Tips & detailed help

Getting a free AI key

Both Google (Gemini) and Mistral hand out free API keys from their developer consoles, and the Query Grouper accepts either. The AI request goes straight from your browser to the provider you chose — SerpHammer has no server in the loop.

What the FatCat simulation covers

Four stages of a Google-style pipeline: HTML structural weighting, Knowledge Graph entity alignment, Murmur3 sparse hashing and dense vector embeddings with cosine similarity. It's educational — it doesn't fetch or score your live site.

How Domain Manager stores data

Your domain list is saved to your free account, so it follows you across devices instead of living in one browser. Import your portfolio in bulk, let the auto WHOIS lookup fill in the details, and set reminders ahead of every renewal.

When advanced is the wrong tool

If the job is quick and mechanical — pull URLs from a sitemap, build a regex for Search Console, open fifty tabs — skip this page and grab the right utility from the main SEO Tools list. Advanced tools earn their setup cost on deep jobs, not quick ones.

Frequently asked questions

What makes a tool 'advanced'?

It goes past paste-and-go: it either needs something from you (an AI key, an account) or models a genuinely complex process. The trade is depth — clustering at scale, a working picture of indexing, portfolio-level domain tracking.

Do I have to pay for the AI?

No. Both Gemini and Mistral offer free API keys, and the Semantic Query Grouper works with either. You create the key on the provider's site and paste it into the tool.

Where do my keywords go when I use the Query Grouper?

From your browser straight to the AI provider you chose, using your key. SerpHammer has no server in the loop and never sees your keyword list.

Does the FatCat visualizer analyze my live website?

No — it's a self-contained simulation. You paste HTML into it and watch a Google-style pipeline process that input. It doesn't crawl, fetch or score anything on the live web.

Why does Domain Manager need an account?

Because a domain portfolio has to outlive one browser: your list, prices and reminders are saved to your free account so they're there on any device you sign in from.

Can I pin these tools?

Yes — the pin on each card here adds the tool to the Pinned row on the main SEO Tools page, so your advanced tools sit alongside your everyday ones.
