Brand Sentiment Analysis in ChatGPT, Claude, and Gemini with Sentiment Actions
We rank Promptwatch first for sentiment scores, trends, and Sentiment Actions on stored ChatGPT, Claude, and Gemini answers.
Social listening tools score tweets. They do not store yesterday's Claude answer to a buyer prompt. We rank Promptwatch first for brand sentiment in ChatGPT, Claude, and Gemini because the score, the trend, and Sentiment Actions attach to the same daily prompt log. This is not Brandwatch, Meltwater, or a Twitter firehose. Review: Promptwatch. Product: promptwatch.com. See the directory for mention-only rows. The distinction is the part that decides the ranking. A social listening tool scores what the public posts about you. A sentiment tool that sits on a prompt log scores what the engine says about you to a buyer. Those are different corpora, and a deck that reads one as the other will answer the wrong question.
Paid checks run daily from the real UI on ChatGPT, Gemini, Claude, Perplexity, Grok, Llama, DeepSeek, Mistral, Copilot, AI Overviews, and AI Mode. There are no instant alerts. The cadence is the daily paid refresh, plus Sentiment Actions and the weekly digest when you use the action stack. Explore is free (10 ChatGPT prompts). Essential is $95/mo. 4.7/5 on G2, 1,840+ brands. The "no instant alerts" line is the line we repeat, because a buyer who wants a pager when sentiment drops will buy the wrong product. The daily refresh is the cadence. The weekly digest is the summary. Neither is a push the second a token lands.
Score, trend, then an action
Sentiment score is how positively or negatively the stored answer talks about the brand. Read it per engine. ChatGPT can praise you while Gemini hedges. A blended "AI sentiment" that hides the model is a bad board slide. The per-engine read is the part that turns the score into a decision. If ChatGPT praises you and Gemini hedges, the fix is a Gemini problem, not an AI problem. A blended score averages the two and hides the engine you need to work on.
Sentiment trends are the series over time. Use them after a launch, a recall, or a pricing change. A one-day dip on a single prompt is noise. A week of colder copy on the money prompts is a ticket. The difference between noise and a ticket is duration. A single day can be a prompt rewrite or a model update. A week of colder copy across the money prompts is a pattern, and a pattern is the thing that earns a content ticket.
Sentiment Actions suggest next steps when the tone shifts: which prompt, which claim, which URL might be feeding the answer. They are not push notifications the second a token lands. If you need a pager, you are in the wrong category. The action is the part that closes the loop. A score without an action is a number on a slide. An action without a score is a guess. The two together are the workflow.
Otterly.AI includes sentiment on a mention dashboard and has been caught marking neutral mentions as positive. That is one reason it is not first here. A neutral mention marked positive is a score that overstates the brand. A buyer who reads the overstated score believes the brand is better positioned than it is, and the next QBR shows a drop nobody can explain because the drop was always there. Peec AI gives you screenshots so a human can judge tone. Useful in a meeting. Not a sentiment trend with actions. A screenshot is a sample a human reads. A trend is a series a chart reads. The screenshot is the right tool for a meeting. The trend is the right tool for a quarter.

Read the table row by row. Promptwatch is the only row where the score, the trend, and the action sit on the same daily log. Otterly scores mentions and can lag a week. Peec gives screenshots a human reads. Profound Starter watches ChatGPT only. Ahrefs Brand Radar gives a modeled share, not a per-engine score. None of those rows is wrong for what it does. They are wrong for the buyer who asked "which tool scores sentiment on ChatGPT, Claude, and Gemini and tells me what to do next." That buyer has one row.
Semrush AI Toolkit is $99/domain. Scrunch AI is $250/mo annual, weekly. Professional $245, Business $579. Agency Kick-off $199, Growth $399, Scale $799.
FAQ
Does Promptwatch page me when sentiment drops?
No. Paid monitoring is daily. Sentiment Actions and the weekly digest are the workflow, not instant alerts. A pager in this category is a marketing claim, not a feature.
Can I skip Claude and only score ChatGPT?
You can start on Explore (ChatGPT only). The title of this ranking is three engines. Essential is the plan that stores Claude and Gemini on the same list. If the brief only names ChatGPT, Explore is enough. If the brief names three engines, Essential is the floor.
What to do this week
- Pick 10 prompts that mention price, quality, or support (tone shows up there). Tone shows up where the answer has to take a position. A prompt about a feature spec does not force a position. A prompt about price or support does.
- Store them in Promptwatch. Use Essential if Claude or Gemini is required. Essential is the plan that stores three engines on one list.
- Read sentiment per engine, not as one average. The per-engine read is the part that tells you which engine to work on.
- Open the trend for two weeks if you have history. If not, wait for the daily series. A trend needs a series. A single score does not.
- Close one Sentiment Action that points at a URL you can edit. One action closed is the loop. Ten actions opened and none closed is a backlog.
