Tools
Free SEO and AI search tools.
Practical tools to find content gaps, plan topic clusters, check citation readiness, and brief writers — the same inputs Gadex uses before production starts. Four of the five run entirely in your browser: nothing you paste is sent anywhere.
- Competitor search gap report See the buyer questions your competitors answer and you don't — turned into a short, prioritized production queue.
- Citation readiness checker Paste a page and score it against twelve structural checks. Every claim carrying a figure with no source beside it is quoted back to you.
- Topical authority map generator Turn one seed topic into a hub-and-spoke cluster with an internal link plan. Paste your existing titles to see which nodes are already covered.
- Internal link opportunity checker Find where a draft should link to pages you already have, with the anchor text and the sentence to put it in — plus which pages nothing links to.
- SEO content brief generator Produce a full writer brief — outline, meta drafts, source rules, fact-check list — with a structure that changes by search intent.
Choosing
Which tool should I start with?
If you do not yet know what to write, start with the competitor search gap report — it is the only one here that involves us doing research for you, and it answers which pages should exist at all. If you already have a page and want to know whether it is any good, start with the citation readiness checker. Everything else is for work already in motion.
What runs in my browser, and what do you see?
Four of the five are pure client-side JavaScript: the citation readiness checker, the topical authority map generator, the internal link opportunity checker, and the content brief generator. Nothing you paste into them is transmitted, logged, or stored — you can disconnect from the network and they still work. The gap report is the exception: it is a form, because a human researches your market and emails the result.
Do I need to sign up or pay?
No. None of the browser tools ask for an email address, and the gap report is free with no call required. We would rather you used them and formed your own view than traded your address for a score.
What can these tools not tell me?
None of them predicts whether an answer engine will cite your page — nobody can, and a tool that claims to is selling something it cannot deliver. They check structure and readiness: whether your answer is stated early, whether figures carry sources, whether related pages are linked. That is the part you control.
What if I want the work done rather than the tool?
That is the service. The tools exist because the inputs they produce — a gap list, a topic map, a brief — are the same inputs we use before production starts. If you would rather not run them yourself, the pricing page sets out what a managed programme costs.
How we sourced this guidance
The advice above is ours, drawn from running content production across the sites Gadex operates. There is no dataset behind it and no sample to cite. Where it describes another company’s product or price, that comes from the vendor’s own public pages and is dated on the page that states it. Our methodology and editorial standards set out how pages here are researched, reviewed, and corrected.
