Keyword Tools

Generate, expand, clean and organise keyword lists entirely in your browser.

These tools handle the mechanical half of keyword research: expanding a topic into variations, cleaning messy exports, removing duplicates, grouping phrases into page-sized clusters and measuring what a list actually contains. They work from the words you provide and never claim to know search volume, difficulty or cost-per-click.

What keyword tools can and cannot do

A generator produces combinations, a cleaner normalises text and an analyser counts what is there. None of that measures demand. Use these tools to build and shape a list quickly, then validate the shortlist against a source with real search data such as Search Console, autocomplete or a licensed dataset.

A workflow that works

Start with a seed list written in your customers' own language. Expand it with modifiers, questions and long-tail patterns. Clean and deduplicate the result. Group the survivors by shared head term, then assign one primary phrase per planned page. Export in whatever format your brief or ad platform expects.

Privacy by design

Every keyword tool on Hashly runs as JavaScript inside your browser tab. Client lists, unreleased product names and confidential campaign terms never leave your device, because there is no server-side processing step to send them to.
