AutoTDK's Chrome extension shows the keywords, traffic, backlinks and Whois details behind any site you visit, and its website adds long-tail ideas, AI writing tools and AI answer checks on credits. Plans run from $9.99 to $99.99 a month, but the pricing page doesn't say how many credits each one buys, every price is shown as half off with no end date, and refunds aren't offered. - **Value for money: C.** Basic is $9.99 a month, inside this category's cheaper quarter, with Pro at $29.99 and Premium at $99.99. But the page doesn't say how many credits any plan includes or what a credit buys, so there's nothing to set the price against, and refunds aren't supported. - **Free plan and trial: C.** Free daily credits on the website, and the extension's traffic, Whois and SEO analysis are described as free. The page never says how many credits a day you get, so you can't tell where free use stops. - **Features: C.** Competitor keywords with volume and difficulty, long-tail ideas from Google, YouTube, Bing, Amazon and more, traffic estimates, backlinks, Whois, AI answer checks and AI writing tools. No title, meta or heading checks are on record, and how far credits stretch isn't stated. - **Ease of use: C.** No rating on record. The extension works on the site you open, but the website's tools run on credits through a login, with nothing to say how many a task uses. - **Platforms and integrations: C.** A Chrome extension plus the website, which its FAQ says works in any mobile browser. No API or integrations are listed. These are ToolGPA's own grades. Graded from this listing, whose facts were read from AutoTDK's own pages and its Chrome Web Store listing on 23 October 2026.

The category's chart of price against score: https://toolgpa.com/charts/seo-extensions ## Keep it, or make your own? **Keep it.** To replace AutoTDK you would be making search volumes for millions of keywords, gathered and kept up to date. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 32 of the 34 other SEO browser extensions grade higher. It costs $119.88 a year. - You could not: Search volumes for millions of keywords, gathered and kept up to date. - You could not: An index of the links between billions of web pages. - You could not: The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept. - You could not: AI features, unless you pay a model provider for each request yourself. A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it. **Tags:** Keyword research, Backlink analysis, AI search visibility, AI features ## Alternatives - [Keywords Everywhere](https://toolgpa.com/tools/keywords-everywhere): Browser extension that shows search volume on the sites you browse.
