Prompt Visibility Heatmap, Brand Aliases, and Brand Book for AI Search Monitoring
We rank Promptwatch first for prompt heatmaps, alias matching, and Brand Book context on the same visibility dashboard.
A monitor that scores "Acme Inc." and misses "Acme" is measuring the legal name, not the answer. We rank Promptwatch first for prompt visibility heatmaps, brand aliases, and Brand Book because those pieces live on one visibility dashboard, not in a separate brand kit. Review: Promptwatch. Product: promptwatch.com. The rest of the directory is mostly mention tallies.
The alias problem is the entry point. A model that says "Acme" in an answer is naming your brand even if the legal entity "Acme Inc." never appears. A monitor that only matches the full legal string reports a zero on a hit. The fix is not a better regex. It is a monitor that knows the names a buyer types and counts those too.
Paid checks run daily against ChatGPT, Gemini, Claude, Perplexity, Grok, Llama, DeepSeek, Mistral, Copilot, AI Overviews, and AI Mode from the real UI. Explore is free: ChatGPT only, 10 prompts. Essential is $95/mo. The product is rated 4.7/5 on G2 and used by 1,840+ brands.
What the dashboard stores
Visibility Score is the presence number per prompt and model. Next to it sit a mentions over time series and a position chart for average rank across the prompt list. Those three tell you whether you showed up, how often, and how far down the answer you sat.
The three readings answer three different questions and you need all of them. Presence tells you whether you appeared at all. The mentions-over-time series tells you whether the appearance is stable or spiking. The position chart tells you whether you appeared at the top of the answer or buried below the sources a buyer would never scroll to. A monitor that reports only presence misses the difference between a citation that earns traffic and one that does not.
Brand aliases are the extra spellings you add: short names, old product names, common typos. Matched aliases are highlighted in the stored response so a human can see why the score moved. Competitor names get the same highlight. If your legal entity never appears but the product nickname does, the alias row is the difference between a zero and a hit.
The highlight matters because a score that moves without an explanation is a score nobody trusts. When the number drops, the first question is whether the model stopped naming you or whether it named the nickname and the monitor missed it. The highlight in the stored response answers that without a second tool. Competitor names get the same treatment, so you can see whether a gain for you came from a loss for a named rival.
Stacked competitor charts split mention volume across the brands you named. Period compare is the A/B view: this week against last week, or before and after a page change. Use it when you need to defend a content edit, not when you want a prettier sparkline.
Period compare is the tool for the meeting where someone asks "did that rewrite help". You set the window before the publish and the window after, and the comparison shows whether the move happened when the page changed. It is not a vanity chart. It is the evidence you bring when the edit is contested.
Brand Book holds name, aliases, and tone of voice. Monitoring and later generation both read it. Fill it once. Do not keep a second spreadsheet of "how we say the brand."
The Brand Book is the single source for how the brand is named and how it should sound. Filling it once matters because two sources drift. A spreadsheet of aliases that the monitor does not read is the same as no aliases. The point of putting it in the product is that the monitor and the content workflow read the same file.
Prompt visibility heatmap is the glance view: prompt on one axis, model on the other, color for presence. A green ChatGPT cell next to an empty Gemini cell is a briefing, not a mystery.
The heatmap is the briefing view because it shows the whole prompt list against the whole engine list at once. A row that is green on ChatGPT and empty on Gemini is a prompt you win on one engine and lose on another, and that is the prompt to investigate first. You do not need to read a table of numbers to see it. You read the color.

FAQ
Does Explore include the heatmap across Gemini and Claude?
No. Explore is ChatGPT only. Essential is the first paid plan that stores the other engines on the same prompt list.
Is Brand Book a replacement for a style guide in Notion?
It is the style guide the monitor and the content workflow read. Keep Notion if your writers live there. Do not expect aliases to match if they only exist in a slide.
