Two Very Different Approaches to Keywords
Semrush is an enterprise SEO platform that costs $100+/month. It pulls data from search engines — search volume, keyword difficulty, competitive rankings, SERP features, backlink profiles. It answers the question: “What are people searching for on Google?”
The AllTools Keyword Extractor answers a different question: “What are the most important keywords in THIS specific text?” It analyzes content you provide and returns ranked keywords using statistical text analysis. It runs in your browser, costs nothing, and never uploads your text.
These tools serve different stages of the SEO workflow. Understanding where each one fits saves you from paying $100+/month for something a free tool handles just as well — or from using a free tool when you actually need search data.
Quick Summary
Choose Semrush if: You need search volume data, competitive keyword research, SERP position tracking, or backlink analysis. You’re running an SEO agency or managing multiple sites where the $100+/month cost is justified by the business value.
Choose AllTools if: You need to extract keywords from existing text — your articles, competitor content, research documents, or any written material. You want instant results with no account, no upload, and no cost.

The Fundamental Difference: Your Text vs Search Data
This is the core distinction that determines which tool you need.
Semrush starts with Google’s search index. You enter a keyword or domain, and it tells you how many people search for that term, how hard it would be to rank for it, and who currently ranks in the top positions. This is invaluable for keyword research — deciding WHAT to write about.
The AllTools Keyword Extractor starts with text you already have. You paste an article, blog post, product page, or any written content, and it tells you which words and phrases are most statistically significant in that text. This is invaluable for content optimization — understanding what your text actually emphasizes.
Neither tool replaces the other. But many people pay for Semrush when what they actually need is text-level keyword extraction — something AllTools does for free.
When Semrush Is Worth $100+/Month
Semrush earns its price for users who need:
- Search volume estimates — knowing that “keyword extraction” gets 2,400 searches/month while “text keyword finder” gets 320/month helps you prioritize topics
- Competitive intelligence — seeing which keywords your competitors rank for and where the gaps are
- Position tracking — monitoring your Google rankings for target keywords over time
- Backlink analysis — understanding your link profile and finding link-building opportunities
- Site auditing — crawling your site for technical SEO issues
If you manage multiple client websites, run paid search campaigns, or need to report on organic traffic growth, Semrush’s data justifies the investment. These are capabilities that require access to search engine data, which no browser-based tool can provide.
When AllTools Does the Job Better
For text-level keyword extraction, AllTools actually outperforms Semrush because it’s purpose-built for the task:
- Paste any text — articles, emails, transcripts, research papers, product descriptions. Semrush only works with search queries and URLs.
- 9 language support — extract keywords from English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, and Arabic text with language-specific stopword filtering.
- Instant hashtag export — one click converts your keywords to social media hashtags. Semrush has no equivalent feature.
- Meta keyword export — comma-separated format ready for HTML meta tags. Useful alongside the Meta Tag Generator.
- Zero privacy risk — your text stays in your browser. With Semrush, any text you paste into their content tools goes to their servers.
- No rate limits — Semrush’s free plan caps you at 10 queries per day with reduced data. AllTools has no limits at all.
A Practical Workflow Using Both
The smartest approach combines free and paid tools where each one excels.
- Research phase (Semrush) — Use Semrush to find high-volume, low-competition keywords in your niche
- Writing phase — Create your content targeting those keywords
- Optimization phase (AllTools) — Paste your draft into the Keyword Extractor to verify your target keywords actually show up as the top extracted terms
- Density check (AllTools) — Use the Keyword Density Checker to ensure your target keyword appears at the right frequency (1-3%)
- Meta tags (AllTools) — Generate meta tags with the Meta Tag Generator using your extracted keywords
This workflow uses Semrush for what it’s best at (search data) and AllTools for what it’s best at (text analysis) — without paying extra for capabilities you can get free.
The Privacy Factor
When you paste text into Semrush’s SEO Writing Assistant or Content Template, that text is sent to Semrush servers for processing. Their privacy policy governs how it’s handled, but the data has left your device.
With AllTools, your text never leaves your browser. The extraction algorithm runs in JavaScript on your machine. You can verify this by opening your browser’s Network tab during extraction — zero data is transmitted. For analyzing confidential documents, unreleased content, or client materials, this difference matters.
The Bottom Line
Semrush and the AllTools Keyword Extractor are not competitors — they solve different problems. Semrush tells you what the world is searching for. AllTools tells you what your text is about.
If you’re paying $100+/month for Semrush mainly to extract keywords from your own content, you’re overpaying. The Keyword Extractor does that for free, privately, and with features Semrush doesn’t offer (hashtag export, meta keyword export, offline use).
Try it now: paste any text into the Keyword Extractor, extract your keywords, and export them as hashtags or meta keywords — all without creating an account or spending a dollar.
