Head-to-head review · Updated June 2026
Keyword Tool vs Wordtune: which one wins in 2026?
Keyword Tool and Wordtune both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. Keyword Tool has raised Bootstrapped, Wordtune has raised $636M across 7 rounds (AI21 Labs, Wordtune parent); Wordtune is the more-funded incumbent; Keyword Tool is the leaner challenger.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
★ Our pick
Pick
Wordtune
Pick Wordtune if you want the better-funded company ($636M across 7 rounds (AI21 Labs, Wordtune parent)).
If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.
The case for Keyword Tool
Keyword Tool has raised Bootstrapped. Founded by Artem Galimov, Leow Kah Thong, based in Hong Kong. Pricing starts at $0/mo.
Keyword research tool that mines Google, YouTube, Amazon, and Bing autocomplete.

- 750+ long-tail suggestions per query, more breadth than most free keyword tools
Where it falls short
- Free version hides search volume, CPC, and trend data, the upgrade pressure is the core complaint
- Search volume accuracy is inconsistent compared to Semrush and Ahrefs, problematic for business decisions
- No competitive analysis feature, you learn what people search but not whether you can rank for it
- Reports of difficulty getting refunds despite the advertised 30-day money-back guarantee
The case for Wordtune
Wordtune has raised $636M across 7 rounds (AI21 Labs, Wordtune parent) (Series D, $300M, May 2025). Founded by Yoav Shoham, Ori Goshen, Amnon Shashua, based in Tel Aviv, Israel. On their site they list 1 named customers including Several million users (per AI21 Labs). Pricing starts at $0/mo.

- Annual pricing at $4.89 to $6.99/mo is half the cost of Grammarly Premium and a fraction of Jasper or Copy.ai.

Where it falls short
- Daily rewrite caps on Free (10/day) and Advanced (30/day) force frequent upgrades for any heavy user.
- G2 reviewers note suggestions can feel repetitive or generic on longer paragraphs, weaker than Claude or ChatGPT directly.
- Outlook integration is web-only, not the Outlook desktop app, which excludes most enterprise users.
- Wordtune is a writing assistant, not a content marketing platform: no SEO, no long-form workflow, no team collaboration.

Switching from one to the other
From Keyword Tool to Wordtune
Export your saved queries and prompt panels from Keyword Tool (most tools support CSV export). Most Wordtune setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Wordtune's data againstKeyword Tool's; one to two weeks of full reconciliation before you cancel Keyword Tool. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Wordtune to Keyword Tool
Same flow in reverse. Export from Wordtune, import to Keyword Tool. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
From either to GrowthManager.ai
We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option
Both Keyword Tool and Wordtuneare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions
Which is better, Keyword Tool or Wordtune?
Honestly: neither one fully solves the problem. Keyword Tool and Wordtune are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick Keyword Tool for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.
How much do Keyword Tool and Wordtune cost?
Keyword Tool starts at $0/mo. Wordtune starts at $0/mo. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.
Do Keyword Tool and Wordtune actually improve your AI visibility, or just measure it?
Both Keyword Tool and Wordtune are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.
What's the GrowthManager.ai alternative to Keyword Tool and Wordtune?
GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
