The best LLM monitoring tools for brand visibility, with the evidence shown.
An LLM monitoring tool asks ChatGPT, Claude, Gemini, Perplexity and other models the questions your buyers ask, and records what they say about your brand. Three things separate one from another: which models it reads, how often it asks again, and whether you can see the answers behind each number. 20 tools compared on exactly that, every fact linked to the vendor's own page with the day we read it.
Which models does each tool track, and how often?
Grouped by the cadence each vendor publishes, in the order AI engines named them. The bold line is the vendor's own model list; the fit line is our read.

How do the LLM monitoring tools compare on models, cadence and evidence?

Can you see the answers behind each number?
A mention rate is a summary of many answers. Before you trust it, you want two things: the answers themselves, and some sense of how far the number could move on its own. Pricing pages rarely say whether a tool shows the raw answer, so here is what they do publish.
- How sure each number is. AI answers vary from run to run. Proofsource puts a 95% Wilson interval on every percentage; the others on our hub list do not publish one on the pages we read. Of the added tools, Evertune samples each prompt up to 100 times per model, and LLM Monitor queries each model from several regions.
- Whether the data leaves the tool. Exports and an API let you check the answers yourself:
- Rankscale: REST API from Pro+; CSV and Google Sheets export from Pro; Data Studio integration and MCP.
- ZipTie: REST API and MCP as a +$10/mo add-on; exports, share links and Search Console included.
- Profound: CSV and JSON exports and an API on Enterprise; no exports or API on the trial.
- Otterly.AI: API and MCP access from Standard (2,000 requests a month), a Google Looker Studio connector, and reports with export.
- Peec AI: Looker Studio integration on Advanced; API access on Enterprise; CSV exports.
- Semrush AI Visibility Toolkit: CSV export (1,000 rows per export, 10 exports a day); an API is not mentioned in the knowledge base.
- Ahrefs Brand Radar: API and MCP access on every Ahrefs plan from Lite, Report Builder, and a Looker Studio integration from Advanced.
- SE Ranking: 25K API credits and MCP access on Core; scheduled reports with the Agency Pack.
- Writesonic: Looker Studio and other integrations on Enterprise; an API is not mentioned on the pricing page.
- Siftly: API and MCP listed in its product menu, plan availability not stated; GA4 and Search Console integration from Growth.
- AIclicks: API, MCP and GA4 integrations from Pro; custom integrations on Enterprise.
- Knowatoa: Reporting stack (API, MCP, Looker Studio, NinjaCat) listed from Growth, not on Starter.
- Scrunch: Looker Studio, query API, advanced API and MCP access on Enterprise only; a reporting dashboard on Core.
- AthenaHQ: API access is a paid add-on on Starter and included on Enterprise; CSV export; BI dashboards (Tableau, Power BI, Looker) on Enterprise.
Proofsource stores every answer with its engine, timestamp and sources, so you can open the exact answer behind any number and the pages it cited. How the interval is computed is on the methodology page.
Which other LLM monitoring tools should you know?
Four more from our sourced compare pages, two of them with LLM in the name.
| Tool | Models tracked | How often answers are re-read | How a number is measured | Price | Best fit if (our read) |
|---|---|---|---|---|---|
| LLM Pulsesource | 5 included: ChatGPT, Perplexity, Google AI Mode, Google AI Overviews and Gemini; Grok, Claude, Copilot, DeepSeek and others as add-ons | Weekly or daily, chosen per plan | Not published | Starter €49, Growth €99, Scale €299 a month with weekly tracking; daily tracking priced separately; Enterprise custom | you want five models included, more as add-ons, and weekly or daily runs with unlimited team members. Proofsource vs LLM Pulse |

Proofsource vs LLM Monitor |
| Evertunesource | 11 AI models; the homepage names ChatGPT, Claude, Perplexity, Gemini, Google AI Mode, Google AI Overviews, Copilot, DeepSeek and Meta | Daily, weekly or monthly | Each prompt sampled up to 100 times per model; prompts drawn from a 150M+ user-prompt panel | Pro $800 a month; Enterprise custom; both through a demo | you are a large brand that wants each prompt sampled up to 100 times per model. Proofsource vs Evertune |
| Brand24source | ChatGPT, Claude, Gemini, Perplexity, AI Overviews, Google AI Mode, DeepSeek, Grok and Copilot | Not published | Runs the prompts you define across LLMs and reports average position, brand score and share of voice | Plans from $249 a month (Individual), $199 a month billed annually; AI Visibility is an add-on on every plan, price not published | you want nine named models as an add-on to Brand24's plans, with average position and share of voice. Proofsource vs Brand24 |
Is brand LLM monitoring the same as LLM observability?
No, and the two get mixed up in search. LLM observability tools trace your own AI application: the prompts it sends, latency, cost and errors. Brand LLM monitoring reads what public models such as ChatGPT, Claude and Gemini say about your market, and every tool on this page does the second.
The same job goes by other names: LLM visibility tool, AI recommendation tracking and daily AI visibility monitoring.
Where is Proofsource weaker for LLM monitoring?
- No hourly runs. Proofsource runs daily or weekly; Rankscale lets you pick hourly per search term.
- 4 models at self-serve checkout. Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI are enabled on a call (Book a demo) or on Managed, while AthenaHQ lists 11 on a self-serve plan.
- Repeat monitoring is a paid feature. The free trial runs 2 scans; Siftly offers a free plan with weekly tracking.
Where it is stronger: every percentage carries a 95% interval and every number opens to the answers behind it, on ChatGPT, Perplexity, Claude and Google AI Overviews from the first scan. Daily or weekly, chosen per plan; the trial runs 2 scans about a day apart.
What buyers ask about LLM monitoring tools
What is an LLM monitoring tool for brand visibility?
Software that asks large language models such as ChatGPT, Claude, Gemini and Perplexity the questions your buyers ask, on a schedule, and records whether your brand is named, how it is described, who is named instead and which sources are cited.
Which LLMs should I monitor?
The ones your buyers use. For most brands that means ChatGPT, Perplexity, Claude and Google AI Overviews, the four in Proofsource's trial and every plan's default panel. Gemini, Microsoft Copilot, Google AI Mode, DeepSeek and others matter more in some markets; Proofsource enables Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI on a call.
How often should LLM answers be checked?
Daily if you act on changes, weekly if you report on trends. In our own sampling, answer sets move 9 to 27% day over day, so one read is a sample, not a fact. Rankscale offers hourly runs per search term; Proofsource runs daily or weekly, chosen per plan, and flags a change once it clears the 95% interval.
Can I try an LLM monitoring tool for free?
Yes. LLM Monitor allows up to 3 prompts and 2 scans with no card, LLM Pulse offers a 14-day trial, and Siftly has a free plan with weekly tracking. Proofsource starts with 2 days of full AI visibility, no card: 25 buyer questions on ChatGPT, Perplexity, Claude and Google AI Overviews, every answer stored.
Which tool monitors the most models?
On a published self-serve plan, AthenaHQ lists 11 models on Starter and Rankscale 9 from Pro. Peec AI lists up to 13 on Enterprise and Evertune 11 models. Brand24 names nine in its AI Visibility add-on. A longer list helps when the plan you buy includes the models your buyers use.
