AI Keyword Research Tool & Free Keyword Finder
A keyword suggestion tool, a search-volume-and-difficulty checker, a keyword clustering engine, and a rank tracker — most competitors sell these as one subscription. nqzai runs all of it inside one chat agent, priced per action instead of per seat.
- Keyword idea generation from live SERP data (related searches + PAA questions) costs nothing extra beyond the normal chat turn — no separate ideation fee.
- Search volume, difficulty, CPC, and search intent are available on demand — free when a keyword's already cached (within 30 days), ~2.45M tokens for a fresh paid lookup otherwise.
- Ideas roll straight into topic clustering, content briefs, written articles, and keyword rank tracking — no exporting a CSV between tools.

What is an AI keyword research tool?
A keyword research tool turns one seed topic or URL into a list of related search terms — the words and phrases people actually type — so content and campaigns can be built around demand that exists, instead of guesses. The "AI" part usually means the tool uses a language model to expand and cluster those terms by meaning and intent, not just by string similarity.
nqzai's keyword tool sits inside its chat agent rather than a standalone dashboard: ask for keyword ideas around a topic, and it pulls related searches and People Also Ask questions from live SERP data, tagged by search intent. From there, the same agent can pull volume/difficulty on the ideas worth checking, cluster your full tracked set into topic pillars, generate a content brief, write the article, and track how it ranks — one continuous workflow instead of five separate tools. Once a keyword is chosen, content optimization tools take over for the writing step, and a full AI SEO toolchain covers the rest of the audit.
Keyword suggestion tool & keyword generator: how the ideation engine works
Ask nqzai for keyword ideas around a topic (e.g. "find keywords around AI agent compliance") and it returns related searches and PAA-style question keywords pulled from live SERP data — the same underlying signal most keyword-suggestion tools use, without a separate export step. This is included in the cost of the chat turn itself; there's no metered "ideation" line item the way volume/difficulty lookups are metered below.
Keyword difficulty, search volume & CPC checker
Once you have candidate keywords, the next question is usually "is this worth targeting" — which needs real numbers, not just an idea list. nqzai's volume/difficulty lookup returns search volume, year-over-year trend, CPC, bid range, competition level, search intent, and the average backlink authority of the pages currently ranking (a proxy for how hard the keyword is to actually win) — not just a single opaque difficulty score.
A keyword already checked in the last 30 days is served from cache at no cost. A keyword outside that window goes to a metered data provider for exact search volume and difficulty — roughly 2.45M tokens for that fresh lookup. There's no free live-data tier beyond the cache; that's the honest shape of the pricing, not a rounded marketing estimate.
Search intent analysis & keyword clustering
Every keyword idea nqzai returns is tagged by search intent (informational, commercial, etc.) up front, so you're not guessing which terms are worth a blog post versus a product page. For your full tracked keyword set, clustering goes a step further: it groups keywords into topic pillars by intent, each with a recommended target page — ranked by an opportunity score that blends keyword-level metrics with your own Search Console impressions, so keywords you're already getting real search traffic for surface ahead of ones that just look good on paper.
Competitor keyword analysis & gap research
Point nqzai at a competitor's domain and it returns keywords they rank for that your own site doesn't — the classic keyword-gap workflow. It uses a metered keyword-gap data provider when one is configured, and falls back to a no-cost SERP scrape otherwise (still costs the normal turn's tokens either way). This is a separate capability from general idea generation — it needs a named competitor domain, not just a topic.
Long-tail & local keyword research
Long-tail, multi-word variations show up naturally in the related-search and PAA-based ideation output — no separate "long-tail mode" is needed since the underlying SERP data already surfaces them alongside head terms.
Local keyword research is a real gap worth stating plainly: nqzai's keyword volume, difficulty, and CPC data resolves at the national (US) level today, not per city or zip code. If hyper-local search-volume-by-metro is the actual requirement, a tool purpose-built for local SEO keyword data will serve that better than nqzai does right now.
Is this a Google Keyword Planner alternative for PPC?
Partially. nqzai gives CPC and volume estimates useful for judging which keywords are worth targeting — and unlike Keyword Planner, doesn't require an active Google Ads account with real ad spend to unlock exact volume ranges (Planner famously buckets volume into wide ranges for accounts with no spend history). What it doesn't do is build or manage ad campaigns; Google Ads keyword-planning API access is currently restricted to genuine campaign-management tools, and nqzai's keyword research doesn't cross into that today.
Keyword research API & rank tracking over time
There's no standalone public keyword-research API today — this is a chat-agent capability, not a developer endpoint. That's a real limitation against API-first tools if programmatic access is the requirement.
What is covered: keywords you save get tracked with position snapshots over time at no extra cost beyond the normal chat turn, so "how has this keyword's ranking moved" is answerable without re-running a paid lookup each time.

Reports tell you what happened. Ask nqzai why.
Keyword tools return lists. The list is not the problem — deciding what to do with it is. nqzai answers the decision, using the same data plus what it already knows about your site.
The report is still produced and saved — it rides along as the evidence for the answer, instead of being handed over in place of one. You can open it, copy it, or push it to your CMS. You just don’t have to read it to find out what changed.
Find, check, and track keywords in one agent
One prompt gets keyword ideas; the same conversation can check volume and difficulty, cluster them into pillars, brief and write the content, and track how it ranks.
Frequently asked questions
What is a keyword research tool and how does it work?
A keyword research tool takes a seed topic and returns related search terms people actually type, usually pulled from related-search data, People Also Ask questions, and autocomplete. nqzai's version runs this as one step in a chat agent: ask for keyword ideas around a topic, and it returns a set of related terms tagged by search intent, pulled straight from live SERP data — no separate dashboard, no CSV export/import loop.
Is there a free keyword suggestion tool, or does it always cost something?
Keyword idea generation from SERP data (related searches, PAA questions) is included in the normal cost of asking nqzai a question — there's no separate paid step for it, unlike tools that meter idea generation itself. That's different from search volume, difficulty, and CPC, which do require a metered data lookup (see below) — the same way most keyword tools split a free ideation tier from a paid metrics tier.
How is keyword difficulty calculated?
Difficulty is a proxy for how much authority it takes to outrank the pages currently ranking for a keyword — nqzai's keyword-metrics lookup returns it alongside search volume, CPC, bid range, competition level, and the average backlink profile of the pages currently occupying page one, so difficulty isn't a black-box score with no context behind it.
What's the difference between a keyword generator and keyword clustering?
A keyword generator produces a flat list of related terms for one seed topic. Clustering takes your full set of tracked keywords and groups them into topic pillars by search intent, each with a recommended target page — so instead of 200 loose keywords, you get a handful of pillars to actually plan content around. nqzai's clustering runs on top of an opportunity score that blends keyword-level metrics with your site's own Search Console impressions, so first-party keywords you're already getting impressions for aren't buried under raw search-volume ranking.
Can I get local or city-level keyword search volume?
Not yet, and it's worth being upfront about that: nqzai's keyword volume, difficulty, and CPC data is resolved at the national (US) level today, not per city or zip code — there's no location-level breakdown in the current keyword pipeline. If hyper-local search volume by metro area is the core requirement, a tool built specifically for local-SEO keyword data is a better fit for that one job. Unrelated to keyword volume: nqzai does have a separate local-business lead search capability, but that finds businesses by area for outreach — it doesn't return local keyword search volume.
Is nqzai a Google Keyword Planner alternative for PPC campaigns?
Partially. nqzai returns CPC and volume estimates useful for judging which keywords are worth targeting in content or ad copy, and — unlike Keyword Planner — doesn't require an active Google Ads account with real spend to unbucket exact volume ranges. What it doesn't do is build, launch, or manage Google Ads campaigns; that's a separate, currently-dormant roadmap item (Google's policy restricts Ads API access to actual campaign-management tools, not keyword-research-only use), not something this keyword tool covers today.
Does nqzai offer a keyword research API?
Not as a standalone public API today — keyword research is a capability inside the nqzai chat product (ask for ideas, ask for volume/difficulty, ask for a competitor gap), not a developer-facing REST endpoint you'd integrate elsewhere. If a raw API is the specific requirement, that's a real gap against API-first competitors and worth factoring into the decision.
Can I track keyword rankings over time (SERP historical data)?
Yes — keywords you save are tracked with position snapshots over time, at no extra cost beyond the normal chat turn, so you can ask how a keyword's ranking has moved without re-running a paid lookup each time. That's rank-tracking history, not full third-party SERP-feature history (featured snippets, PAA ownership, etc.) — it tracks your own saved keywords' positions, not a general historical SERP database.
