AI Search Monitoring Tools: What to Use and How to Choose
Compare the best AI search monitoring tools by price, prompts and engines as of October 2026, with honest pros, cons and a checklist for choosing.
Key takeaways
- AI search monitoring tools track whether and how AI engines mention and cite your brand, using fixed prompts run on a schedule.
- As of October 2026, entry prices run from about €25 to $99 a month, and prompt allowances from 10 to 200.
- The deciding factors are engine coverage, run frequency, access to raw answers, competitor detection and price per prompt.
- Pick one tool for a month on real prompts before committing; vendors differ most in what is gated behind add-ons or enterprise plans.
AI search monitoring tools run a fixed set of prompts on engines such as ChatGPT, Gemini, Perplexity and Google AI Overviews, store every answer, and report how often your brand is mentioned, where it appears, how it is described and which sources are cited. As of October 2026 the main options are GeoGen, Otterly, SE Visible, Semrush’s AI Visibility plan, Writesonic GEO, Ahrefs Brand Radar, Profound and Peec. Below is how they compare and how to choose.
What do AI search monitoring tools do?
They replace the manual routine of typing questions into chatbots and writing down what comes back. A tool gives you:
- Repeated measurement. AI answers change between runs, so the tool runs each prompt daily.
- Stored evidence. You can open any answer and read it.
- Comparison. Your mentions next to competitors’, by engine and country.
- Sources. The domains and URLs the AI cites, which is where you earn visibility.

How do the best AI search monitoring tools compare?
Prices and limits were read from each vendor’s own pricing page in October 2026 and change often. Confirm before buying.
| Tool | Entry price | Prompts at entry | Engines | Best for |
|---|---|---|---|---|
| GeoGen | €25/mo (€20 yearly) | 10 | 16 available; pick 2 to 7 by plan | Many engines, many countries, agencies |
| Otterly | $29/mo | 15 | 4 (ChatGPT, AI Overviews, Perplexity, Copilot); Gemini, AI Mode, Claude as add-ons | Small teams wanting simple setup |
| SE Visible | $99/mo | 200 | 5 (ChatGPT, Gemini, AI Mode, Perplexity, AI Overview) | Most prompts per dollar |
| Semrush AI Visibility | $99/mo per domain (annual) | 25 | ChatGPT, Google AI, Gemini, Perplexity | Existing Semrush users |
| Writesonic GEO | $99/mo ($79 annual) | 50 | ChatGPT, Gemini, AI Overviews | Teams also wanting content tooling |
| Ahrefs Brand Radar | From €47/mo (Index from €179/mo) | Custom prompts | 6, plus Claude | Existing Ahrefs users |
| Profound | Enterprise, custom; free 7-day trial | 50 in trial | Up to 9 | Large organizations needing SSO, API |
| Peec | Starter, Pro, Advanced, Enterprise | Not published on page | Not published | Plans priced at sign-up |
Vendor caveats worth knowing: Otterly’s page showed two price sets for the same plans (Lite $29 or $25, Standard $189 or $160, Premium $489 or $422), and says annual billing is 15% off. Profound’s page listed a trial and Enterprise, with no self-serve price. Peec’s page names plans without prices.
How does GeoGen compare, honestly?
GeoGen is an AI visibility platform. It runs prompts daily on 16 engines: 10 read as a user sees them (ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity, Microsoft Copilot, Mistral, Brave Leo, Naver AI, Claude Haiku) and 6 queried through the model API (DeepSeek, MiMo, Grok, Qwen, Claude Sonnet, Claude Opus).
| Plan (EUR, ex-VAT) | Monthly | Yearly, per month | Brands | Engines | Prompts |
|---|---|---|---|---|---|
| Micro | €25 | €20 | 1 | any 2 | 10 |
| Standard | €75 | €60 | 2 | any 4 | 50 |
| Growth | €239 | €199 | 5 | any 6 | 150 |
| Pro | €475 | €399 | 15 | any 8 | 300 |
| Custom | Contact sales | Unlimited | All 16 | Unlimited |
Pros: unlimited countries, languages and tags on every plan; auto-detected competitors; recommended actions with a task board; LLM traffic from a tracking script; a REST API, CLI and MCP server; multi-brand pricing that works out to about €26.60 per brand per month on Pro.
Cons: the entry plan holds 10 prompts; it does not track Llama, Meta AI, Yandex Alice, GigaChat, Baidu ERNIE, Doubao or Kimi; query fan-outs exist only for Grok and Perplexity; there is no free plan. If you need many prompts for one brand at the lowest price, SE Visible is cheaper per prompt.
Which tool fits which situation?
- You want the cheapest way to start. GeoGen Micro (€25/mo, €20 billed yearly) or Otterly Lite ($29/mo). Both cap you at 10 to 15 prompts, which is enough to learn the workflow and test whether AI answers matter in your category.
- You need breadth of prompts for one brand. SE Visible: 200 prompts at $99 a month is the lowest cost per prompt among the self-serve plans listed.
- You already pay for an SEO suite. Semrush and Ahrefs add AI tracking to a familiar interface. Check what is included in your current plan versus an add-on, since both charge separately for AI features.
- You run several brands, markets or client accounts. Look at workspace pricing and roles. GeoGen workspaces have their own billing, limits and credits, with Viewer, Editor and Admin roles, which suits agencies. Agencies that need a company-branded dashboard can show their own logo; for specifics, talk to GeoGen.
- You need procurement-grade controls. Profound’s Enterprise plan lists SSO/SAML, SOC 2 compliance and API access. GeoGen’s Custom plan is credit-based for volume; contact sales.
- You want to check Claude or AI Mode too. Otterly sells them as add-ons (Claude from $29/mo on Lite); GeoGen includes both Claude models and Google AI Mode in its 16 engines, selected by plan.
What does a good setup look like in the first month?
- Week 1: Add your brand, three to five competitors and 20 to 30 prompts across discovery, comparison and alternatives. Set country and language per prompt.
- Weeks 2 to 3: Let daily runs accumulate. Read ten raw answers and ten cited sources before looking at any score.
- Week 4: Pick the five prompts with the biggest gap between you and a rival and assign one action each. Record the baseline visibility rate.
After that, review weekly and report monthly. The operating routine is covered separately.
How do you choose?
Work through this list:
- Which engines do your buyers use? Make sure they are in the plan, not add-ons.
- How many prompts? Count 20 to 50 per brand to start.
- How many brands, clients or markets? Per-domain pricing multiplies quickly.
- Can you see raw answers? If not, you cannot validate the score.
- Does it show competitors and citations? Mentions alone do not tell you what to do.
- Does it help you act? Recommendations and task tracking matter once the data arrives.
- Do you need an API or export? Required for client reporting and BI.
What should you ask a vendor before you pay?
Pricing pages hide the details that decide value. Ask these in a demo or trial:
- How is each engine collected? As a user sees it, or through the model API? The two can differ, and the vendor should say which applies per engine.
- What counts as a prompt? One prompt on one engine in one country may be one unit or several. GeoGen charges credits: one credit is one run of one prompt on a scraped engine, while API engines cost more (Grok and Qwen 3 cost more, Claude Sonnet 9 and Claude Opus 15).
- What happens at the limit? Overage fees, such as Ahrefs’ per-check overage on its Index plan, change the real monthly cost.
- Which engines are add-ons? Otterly lists Gemini, Google AI Mode and Claude as paid add-ons on top of its base plans.
- Can you export the data? Check CSV, API or both before you commit to reporting on it.
- How long is data kept? Trend lines need history; Profound lists all-time data history on Enterprise.
Why do the numbers differ between tools?
Because AI answers vary, engines are read in different ways, and each vendor defines its metrics. Do not compare a visibility figure from one tool with another’s; compare trends within one tool. The authors of the original GEO paper reported that GEO methods can boost visibility by up to 40% in generative engine responses in their tests, which is a reason to measure change over time.

Frequently asked questions
What is AI search monitoring?
AI search monitoring is the practice of tracking how AI engines such as ChatGPT, Gemini, Perplexity and Google AI Overviews mention, describe and cite your brand. It runs a fixed set of prompts on a schedule, stores each answer, and reports visibility, position, sentiment and sources.
What is the best AI search monitoring tool?
It depends on your constraint. For the lowest entry price across many engines, GeoGen; for the most prompts per dollar, SE Visible; for enterprise features, Profound. Test two tools on the same 20 prompts for two weeks and compare answers, not dashboards.
Is there a free AI search monitoring tool?
Not a full free plan from the vendors compared here. Profound offers a free 7-day trial with 50 prompts on three engines, and some tools run trials. GeoGen has no free plan; its Micro plan starts at €25 a month, and Micro and Standard come with a 7-day free trial on monthly billing. Manual checks are free but do not scale.
How much do AI search monitoring tools cost?
As of October 2026, self-serve plans start between roughly €25 and $99 a month. Costs rise with prompts, engines and brands: GeoGen Pro is €399 a month billed yearly for 15 brands, and Otterly Premium is $489 a month for 400 prompts.
How is AI search monitoring different from LLM monitoring?
AI search monitoring measures what AI engines say about your brand, a marketing task. LLM monitoring usually means developer observability, tracing and debugging your own AI application. They are different products for different teams, so use the right term when searching.
How often should AI search be monitored?
Daily, if the tool allows it. AI answers vary between runs, so one weekly check is a sample. Judge trends over weeks using averages rather than single observations.
