Keyword Tool
Keyword Tool sends a seed keyword to 15 platforms' live autocomplete and suggest endpoints — including Google, YouTube, Amazon, and TikTok — and returns the unique suggestions as long-tail keyword ideas, enriched with search-volume and CPC data pulled from Google's and Bing's ad platforms. Paid plans add historical tracking, an API, and a connector for AI assistants.
Keyword Tool holds no keyword index of its own — it queries 15 platforms' live autocomplete/suggest endpoints (Google, YouTube, Amazon, Bing, TikTok, and more) and enriches the results with search-volume and CPC data pulled from Google's and Bing's own ad platforms, the same live-scrape-plus-ad-data pattern any developer can wire up directly.
What you lose building it yourself
- ✕One dashboard querying all 15 platforms' autocomplete at once, instead of scripting each endpoint separately
- ✕Up to 48 months of historical volume/CPC data, pre-tracked
- ✕A ready-made API and AI-assistant connector instead of building your own
Why people still pay
One platform's autocomplete pull is a weekend build, but Keyword Tool scrapes and normalizes suggestions across 15 platforms, tracks volume/CPC history for up to 48 months, and ships a ready API and AI-assistant connector — reproducing all of that, and keeping each platform's scrape working as its endpoints change, is the ongoing maintenance being paid for.
WEEKEND CLONE
The core mechanic is a live scrape: query a platform's public autocomplete/suggest endpoint with a seed keyword prefixed and suffixed by each letter and common question words, collect the unique suggestions, then pull volume estimates from a keyword-data API. A single-platform version is a realistic weekend build with an AI coding tool; matching all 15 sources plus historical volume tracking is a bigger, ongoing lift.
StackA platform's public autocomplete/suggest endpoint (Google, YouTube, Amazon, etc.) · a script iterating each letter/question-word prefix per keyword · a keyword-data API (e.g. DataForSEO, or Google Keyword Planner directly) for volume and CPC · a spreadsheet or small database to store results.
Build a Python script that takes a seed keyword, queries Google's public autocomplete suggest endpoint prefixed with each letter of the alphabet and with question words (who, what, why, how, where), and collects the unique suggestions returned. Deduplicate the results, then look up monthly search volume for each suggestion using a keyword-data API (e.g. DataForSEO), and export everything to a CSV file sorted by volume. Cap the run at 500 suggestions per keyword to keep it fast.
Similar tools
Free alternative: Google Keyword Planner — free with a Google Ads account and gives real keyword ideas plus search volume from Google's own data, but it doesn't scrape the other 14 platforms (YouTube, Amazon, TikTok, App Store, and the rest) or return raw autocomplete-style long-tail phrasing.
QUESTIONS
Is Keyword Tool's free version actually free?
Yes — its own site allows unlimited free autocomplete-based keyword lookups with no account, generating 750+ suggestions per search; search volume, CPC, and competition scores require a paid plan.
Does Keyword Tool offer an API?
Yes — every paid plan, including the cheapest, includes API access and a direct connector for AI assistants, per its own pricing page.
How is Keyword Tool's search volume different from Ahrefs' or Semrush's?
It's enriched from Google's and Bing's own ad-platform data (partly via Google Keyword Planner) rather than an independent clickstream panel, so expect it to track closer to what you'd see in Google Ads than to clickstream-based tools.
