Each Tool, Honestly
llmstxt.studio
$19-49/moFull lifecycle GEO platform. Generate a spec-compliant llms.txt file in 30 seconds. We auto-generate 40 prompts from your site content and run them continuously -- one every 10 minutes, 144 checks per day. Live activity feed. Competitor tracking on every prompt.
The only platform that connects llms.txt generation to continuous citation monitoring. No manual prompt setup. No enterprise sales calls. Sign up, point it at your domain, and see who AI recommends in your space.
Promptwatch
$99-579/moMulti-LLM monitoring across 10+ AI engines. You write the prompts manually -- 50 to 350 depending on your plan. Includes crawler logs, enterprise dashboards, and detailed analytics. The most comprehensive option if budget is not a concern.
The trade-off: you are paying 5x more and doing more manual work. No llms.txt generation, no auto-prompt creation. You bring the strategy; they provide the monitoring infrastructure.
SEMrush / Ahrefs
$100-400/moThe traditional SEO heavyweights are adding AI features. Keyword research, backlink analysis, rank tracking -- these tools are excellent for traditional SEO. Their AI visibility features are newer and less mature, typically limited to Google AI Overviews.
If you already pay for SEMrush or Ahrefs, check their AI features before buying another tool. If you do not already use them, they are expensive for GEO alone.
Otterly.ai
VariesAI search monitoring focused on tracking brand mentions across AI engines. Provides visibility into how AI search engines represent your brand. Less focused on the full lifecycle -- no llms.txt generation or automated prompt creation.
Manual Approach (DIY)
$0Write your llms.txt file by hand. Open ChatGPT and Perplexity. Ask questions about your business. See if you get cited. Check back next week.
It works. It is free. It is also tedious, inconsistent, and easy to forget. You will not catch trends. You will not get competitor data. You will not have a live feed. But if your budget is zero and your patience is high, this is a legitimate option.

Our Take
We built llmstxt.studio because we looked at the GEO tool market and saw a gap. Enterprise tools that charge $99+ per month for manual prompt management. Traditional SEO tools bolting on AI features as an afterthought. And a lot of businesses doing nothing because the options were too expensive or too complicated.
We are not pretending to be the best choice for everyone. If you are a Fortune 500 brand that needs 10-engine monitoring with custom reporting, Promptwatch is a better fit. If you already pay $300/mo for SEMrush, check their AI features first.
But if you want the full GEO lifecycle -- generate your llms.txt, monitor 40 prompts continuously, see who AI recommends instead of you -- at a price that does not make you wince, we built this for you.
