Add a niche and a topic, set any keywords you need to hit, then generate.
One brief. Eight kinds of content.
Write the niche and the topic once, then generate whichever format you need. Set your keywords and the density you want them at, and see exactly what you actually got.
Keyword Density You Can Actually Verify
Most generators accept a keyword list and quietly ignore it. This AI content generator turns your targets into instructions a model can follow, then counts what came back and shows you the difference.
Targets become counts
A percentage is a poor instruction. Language models are far better at hitting "use this phrase 14 times" than "reach 1.5% density", so your targets are converted into occurrence counts before the brief is sent. That conversion is most of why the numbers land close.
Then measured, not assumed
Every result is recounted against your keywords and reported per phrase: what you asked for, what you got, and how many times it actually appeared. Plurals and simple variants count, because that is how a reader and a search engine both see them.
Fix it without paying again
The result is editable in place and the density readout updates as you type. A keyword that came back light can be worked in by hand for free, instead of spending another generation and hoping the second attempt lands better.
From a Niche to a Finished Draft
Four fields do almost all the work. Everything else is refinement you can skip.
- 01
Describe the niche and the topic
The niche is who the writing is for — B2B SaaS, dental clinics, home fitness. The topic is what this specific piece is about. These two fields carry most of the quality; a vague topic is the single most common reason AI writing comes back generic.
- 02
Set your keywords and targets
Add up to five phrases, each with the density you want it at. A running total warns you when the combined figure crosses into keyword stuffing, which is the number that actually ruins copy — three keywords at 3% each reads as spam even though none looks extreme alone.
- 03
Pick a format and a length
Eight formats, from a full research article to an Instagram caption. Length runs from 100 to 1,500 words on every one, with each format's sensible range marked on the slider so you can see when you are asking for something a platform will truncate.
- 04
Generate, then check the numbers
The result arrives with a per-keyword density readout. Edit it in place, copy it, download it as Markdown, Word or plain text, or hand it straight to the reword generator or the plagiarism checker.
Eight Formats, One Brief
Every format takes the same niche and topic, so you can produce a whole campaign from one setup without retyping anything.
| Format | Best length | What you get |
|---|---|---|
| Research article | 800–1,500 words | Sectioned and in-depth, closed with a references list to verify |
| Blog post | 600–1,200 words | Hook, subheadings, short paragraphs, an actionable takeaway |
| Tweet / X | 100–250 words | One post, or a numbered thread with every part inside 280 characters |
| LinkedIn post | 100–400 words | A hook line that survives the "see more" fold, then short paragraphs |
| Facebook post | 100–250 words | Conversational, phone-first, written to earn a comment |
| Instagram caption | 100–200 words | Scroll-stopping first line, deliberate pacing, a hashtag block |
| YouTube script | 600–1,500 words | Spoken-word script with a 15-second hook and timestamped sections |
| Product description | 100–400 words | Outcome-led opener and feature-to-benefit bullets |
Four Things That Change the Result
What an AI content generator should actually do
Most tools in this category do one thing: take a prompt and return prose. That is the easy part. The hard part — the part that decides whether the output is publishable — is control. Can you tell it who the writing is for? Can you require that specific phrases appear, at a specific rate, and then confirm they did?
This AI content generator is built around that second question. You give it a niche and a topic, choose one of eight formats, and optionally set keywords with the density you want each one held to. It converts those targets into instructions the model can follow, produces the piece, and then measures the real output against what you asked for.
Why keyword density is usually a lie
Ask a language model to "maintain 1.5% keyword density" and it will agree, then miss. Models do not count as they write; a percentage is an abstraction they cannot verify against a document that does not exist yet.
Ask the same model to use a phrase about fourteen times in a nine-hundred-word piece and the hit rate improves dramatically, because that is a concrete, countable instruction. So the brief is written in occurrences, and the interface reports percentages — each side of the exchange gets the format it handles best.
Density here is measured the standard way: occurrences divided by total words. A two-word phrase appearing twelve times in a thousand words is 1.2%. That under-states the phrase's true footprint, but it matches what Yoast and most SEO tools report, and a number that agrees with the rest of your stack beats one that is technically righter and looks broken.
What counts as a use
Matching is case-insensitive and respects word boundaries, so "cat" never counts inside "category". For English it also folds simple variants: "churn reduction", "Churn Reduction" and "churn reductions" all count toward the same phrase, which is how both a reader and a search engine treat them.
For the other twenty languages the match is exact. English plural and tense rules applied to Spanish or Turkish would invent matches that are not there, and a meter that over-reports is worse than one that occasionally under-reports.
Where this fits with the rest of the toolkit
Generation is the first step, not the last. A draft usually wants tightening, and anything you intend to publish is worth checking against what is already online. Both are one click from the result pane: send the piece to the reword generator to rewrite a section that reads flat, or to the plagiarism checker to confirm nothing in it overlaps a published source.
What it will not do for you
Research-article mode ends with a references list, and those references are generated by the model. They can look entirely plausible and not exist. The tool labels them unverified for exactly that reason, and you should treat the list as a starting point for your own sourcing rather than as citations.
It also will not rescue a vague brief. "Write about marketing" produces the kind of forgettable copy this category is known for. The tool's job is to be controllable; deciding what is worth saying is still yours.
