Best for free long-tail ideas from a dozen sites
Keyword.io is a free web tool that collects autocomplete suggestions from Google, Amazon, YouTube, eBay, TikTok and seven other sites, with no account needed to search. It shows suggestions only: no volume, CPC, difficulty or trend data. Amazon and some other sources are rate limited, and there's no API. You'll need a second tool to decide which ideas are worth writing about.
Who Keyword.io is for
- Fits if you want a list of autocomplete ideas and don't need any numbers next to them
- Works for Amazon or eBay sellers who want the words shoppers type into those search boxes
Who Keyword.io is not for
- Skip it if you need search volume, CPC, difficulty or trends, as it shows none of them
- Tight if you lean on Amazon suggestions, since that source and some others are rate limited
- Not for you if you want to scrape or resell the data, which its terms forbid without written permission
- Watch out: it's web only with no API, and lists leave only as text or through the clipboard
- Watch out: saving lists needs a free account, even though searching doesn't
Why Keyword.io gets a 2.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

- DFeaturesOne narrow job: autocomplete suggestions from 12 sites, plus 20 question phrasings at a time. There's no search volume, CPC, difficulty or trend data, so you need another tool to choose between the ideas.
- BEase of useNo rating on record. There's nothing to set up: type a word, pick a source, get a list. Searching needs no sign-up.
- CPlatforms and integrationsWeb only, with no integrations or API. Lists go out as text or to your clipboard.

Keep Keyword.io, or make your own?
Keep it
Keyword.io is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.8 is higher than 44 of the 51 other keyword research tools we grade.
What you could not
- Search volumes for millions of keywords, gathered and kept up to date.
- Search data for YouTube topics and channels.
What this rests on. Keyword.io’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
