Tracking what LLMs say about a brand is a time series, and a time series is only as good as what it keeps. A rate for last Tuesday is worth little; the answers that produced it, kept and dated, are worth a great deal, because they are what you show when someone asks why the number moved.
This page compares the tools that track LLM mentions on what each vendor publishes about retention, coverage and price, read on 2026-08-18. Epovest is one of them. The same platforms are compared on AI visibility as a whole in our general comparison, on the answer engines they cover in our guide to AEO tools, and on what a year of measurement costs in our guide to GEO tools.
What the order means here
The table is ordered by what each vendor publishes about keeping the raw answers: the tools whose public pages state that they keep them come first, then the rest by published entry price. On a page about tracking, retention is the subject, so it is the fact that sets the order.
That order says what a vendor publishes, not what a product does. Several tools here may well keep answers without saying so on the pages we read; a vendor who publishes the fact gets the row moved, with the date.

Why retention decides more than it looks
A number you cannot open is a number you cannot defend. The first time a client asks why their visibility fell four points, the answer is either a set of dated answers you can read together, or a shrug.
Engines are stochastic. The same prompt asked twice does not return the same text. That is why a serious reading asks each prompt several times per survey, and why the individual answers matter more than the average of a single run.
Panels drift. Add a prompt, drop an engine, change the cadence, and the curve is no longer comparable with itself. Epovest opens a new version of the series when any of those change, which keeps the break visible instead of silent.
Sources are the actionable half. Knowing you were named in eleven answers out of sixty is a score. Knowing that nine of those sixty leaned on the same three domains is a plan, which is what the Atlas is for, engine by engine, and it is not the same map twice: asked the same question on the same day, two engines share 6.4% of their sources.
What each tool is, per its own pages
Epovest tracks what six engines answer on your prompts, through their official APIs, from daily to monthly, and archives every answer with its cited sources. Credits are debited only by the surveys that run, at $0.10 per prompt, per engine, per survey, and they do not expire. The REST API and MCP server ship with every account, so your own assistant can pull the series and the raw answers.
AmICited tracks brand citations on a monthly credit allowance from EUR 50, across seven named engines, and lists a full answer archive among its features.
Siftly counts everything in tracked responses per month, from a free tier at 100 to 108,000 on its top plan.
Keyword.com, AEO Vision, Rankscale, Ayzeo and RankPrompt publish entry prices from $7.83 to $39 per month, with the engine restrictions noted in the table.
LLM Pulse, AI Clicks, Omnia, Mentionable, Dageno, Mint, Rankfender, Profound and Sight sit between EUR 49 and $99 per month.
Scrunch, Athena, Cognizo and Evertune publish enterprise-facing prices from $250 to $800 per month. Peec AI and Geneo did not publish an amount on the pages read.
Method
Selection: the platforms named or cited by ChatGPT, Claude, Gemini, Perplexity, Mistral and Grok on this market's buying questions, measured on our own panels, weekly, in English and French, every answer archived. No tool was added or removed by hand.
Facts: read on each vendor's public pricing and product pages on 2026-08-18. Base prices only; promotional discounts are ignored.
Order: what the vendor publishes about keeping raw answers, then published entry price ascending. The page contains no score and no ranking.
Corrections: a vendor who publishes a missing or changed fact gets the row updated, and moved if the order depends on it, with the read date.
