Terms and Entities, Not Variants
Related concepts, the other ways people say the same thing, the level above and below, and the names that keep appearing alongside — rather than the keyword with a plural and a preposition added.

LSI Keyword Generator
Google says LSI keywords are not a thing. The problem you came here with — covering a topic properly — is real.

What Can the LSI Keyword Generator Do
The term is borrowed from something Google does not use, but the job underneath it is ordinary and real. Below: what comes back, why each item is there, and how it gets checked against what you wrote.
Each One’s Reason
Every term arrives with what it is doing here — a sub-topic a reader will expect, a term of art the audience uses, an entity the subject cannot be discussed without.
Checked Against Your Draft
Paste what you have written and the list splits in two: covered, and missing. Missing is the useful half, and it usually contains the part you assumed everyone already knew.
How to Find LSI Keywords with AllyHub
Three steps from a topic to a list of what your draft has not covered.
01
Name the Topic
The subject and who the piece is for. Paste the draft too if one exists — the answer changes a lot depending on what is already in it.
02
It Maps the Territory
It works out the sub-topics, the vocabulary that audience uses, the entities involved, and the questions the subject raises, then attaches a reason to each.
03
Cover the Gaps
Work down the missing half and decide which gaps are worth filling — some will not be. Save the run as a Playbook so the next piece starts further along.
Why Choose AllyHub’s LSI Keyword Generator
The name is folklore. The work it stands in for is not.
LSI Is Not a Thing
Google’s John Mueller has said it plainly, twice: there is no such thing as LSI keywords. Latent semantic indexing was a technique for small fixed document sets and was never how the web got searched. It seemed worth telling you on the page you arrived at looking for them.

Variants Are Not Relations
Most tools with this name return the keyword rearranged — plurals, word order, a preposition swapped, the same phrase with best in front of it. Those are spellings of one idea, not the surrounding ideas. A reader who wants the topic covered is not looking for the phrase again.

Inserting Them Does Nothing
There is no density to hit, and dropping a term into a sentence that did not need it achieves nothing. The point of knowing a term is missing is that the idea behind it is missing. An absent idea is worth knowing about; an absent word is not.

One Territory, Many Pieces
Nobody writes one article about one subject. Once the map of a territory exists — its sub-topics, its vocabulary, its entities — the tenth piece in that territory starts from it rather than rebuilding it. Your AllyHub never starts from scratch again, so the mapping gets faster every time.

Who Uses AllyHub’s LSI Keyword Generator
Writers whose draft feels thin, SEOs writing briefs, anyone covering an unfamiliar field, and support teams mapping a subject.
When the Draft Feels Thin
You have written the thing, it is accurate, and it still reads like an outline of a better article. The gap is almost never style — it is a handful of sub-topics a reader expects that never occurred to you, because you already know them.
SEOs Writing Briefs
A brief handed over with five keywords in it produces an article about five keywords. One that lists what the topic contains and why gives a writer something to work from, and removes the review round where you list what is missing.
Covering an Unfamiliar Field
The agency won a client in an industry nobody there has worked in, and the first draft will be visibly written by an outsider. What gives that away is not errors — it is the obvious things a practitioner would never leave out.
Support & Documentation Teams
A help centre article has to answer the question and the four adjacent ones, because a reader who has to search twice has already had a bad time. Mapping the subject beforehand is how the second search gets avoided.

FAQs About LSI Keyword Generator
The name, the numbers, checking a draft, and reusing the map.
What is an LSI keyword generator?
A tool that returns terms related to a subject. The name refers to latent semantic indexing, which is not something search engines use — so treat "LSI keywords" as the common name for a real job rather than as a technical category. The job is working out what a topic contains.
Is AllyHub’s LSI keyword generator free?
Yes, one topic at a time. Mapping a set of related topics together, longer drafts, and keeping the map so later pieces in the same territory reuse it are on the paid plans.
Why are there no search volumes?
Because they would be misleading here. Volume figures for related terms are third-party estimates rather than anything a search engine publishes, and a number sitting next to a term turns it into a target when it is really a topic — which is how people end up writing three paragraphs about a phrase instead of covering the subject.
Can it check something I have already written?
That is the more useful way to use it. Paste the draft and the list comes back split into what you covered and what you did not, which is a shorter and much more actionable thing than a list of terms with no relationship to your text.
How is AllyHub different from other LSI keyword generator tools?
Most return the keyword in other arrangements and leave you to guess what to do with them. Here each term comes with why it belongs, the list is checked against your actual draft, and the map of a subject is kept so the next piece about it does not start from nothing.
