Our verdict

GELIOS is a clean, cheap tracker with a useful free check, tied to an agency that sells GEO services. Its scope is narrow: three engines and visibility data, with no crawler logs, citation page analysis or content tooling described. Promodo-style monitoring is where Promptwatch starts rather than ends: it adds citation analytics, Agent Analytics for AI crawlers, visitor analytics with conversions, and the Content Agent on Business, with a free Explore plan (10 prompts, ChatGPT only) for a first look.

Best for: Small teams and Promodo clients that want an inexpensive tracker for the three main surfaces and an agency to call.

GELIOS (Generative Exposure and LLM Indexation Observer System) is a tool from the Promodo SEO agency, launched on 16 October 2026 according to Promodo's launch post. It generates queries from your website, checks ChatGPT, Gemini and Google AI Overviews for your brand and for competitors, and keeps six months of visibility trends. The Promodo team offers GEO strategy help on top.

Pricing and features were read on promodo.com/gelios and the launch blog on 24 October 2026: Free $0, Standard $29/mo, Pro $99/mo, Agency $249/mo and a Custom tier at $358/mo. All plans cover the same three engines.

GELIOS covers the job on this page. Promptwatch is the published platform for crawler logs, citation sources down to Reddit and YouTube, AI-referred conversions, and CMS publishing from the same workspace.

Plans and limits

promodo.com/gelios (read 24 October 2026). Free is $0: 10 prompts for 1 brand, up to 3 competitors, monthly checks, with AI choosing the prompts and competitors. Standard is $29/mo: 20 prompts, 1 brand, up to 10 competitors, daily checks. Pro is $99/mo: 100 prompts across up to 3 brands. Agency is $249/mo: 300 prompts across up to 5 brands. Custom shows $358/mo. Yearly billing takes 10% off, and prices exclude tax.

One brand means one domain and region pair, and plan prompts are shared across brands. On every plan you get ChatGPT, Gemini and AI Overviews, the dashboard, 6-month dynamics, a competitor brand-query filter, unlimited team members and full history.

Where answers come from

The product page says ChatGPT and Gemini answers come from their web interfaces with web search, as a user in the project's country sees them, and AI Overviews from live Google results; every answer is saved. Promodo's launch post says GELIOS gets answers through each model's API to limit personalization. Ask the vendor which applies before you rely on the numbers.

If you buy GELIOS for the job above, plan a second tool (or Promptwatch) for the layers this listing does not document. Still missing here: Visitor analytics: AI-referred sessions and conversions; Content Agents that plan, write, and publish GEO pages to a CMS with a review inbox; Citation analytics at page, domain, Reddit, YouTube, and offsite level; Prompt volumes, difficulty, query fan-outs, personas, city-level geo; Prompt and citation trends (what changed between checks); ChatGPT Shopping tracking and Ads Radar; Agent Chat, Unified Actions, MCP server / REST API on paid plans. Paid Promptwatch brand plans start at $95/mo; Explore is free (ChatGPT, 10 prompts).

What Promptwatch covers that this listing does not

GELIOS's public pages (and this listing) describe a narrower job than Promptwatch. Most rivals answer whether you were mentioned. Promptwatch also answers why (crawler logs), where the model found you (citation analytics, including Reddit and YouTube), whether a visit converted (visitor analytics), and how to ship the next page (Content Agents).

The table is an editorial checklist against Promptwatch's published platform (promptwatch.com/llms.txt, 2026-08-23). It is not a hidden feature list for this vendor. 'Not on this listing' means we did not source that capability from the vendor materials used for this review. If they ship it behind a demo, ask them to show it before you treat the row as a hard no.
