Answyn vs Promptwatch: which AEO platform should a UK brand buy?

Promptwatch does two things here that deserve credit before the argument starts. It publishes a monthly answer cap, which almost nobody in this category does, and it includes API and MCP access on its entry plan, which is unusually generous.

Promptwatch's published caps make the arithmetic unusually easy, so it is worth doing properly.

Essential is 50 prompts across four models, which is 6,000 answers a month at $95, about £70. That is a little over a penny an answer and it is the cheapest entry point of any platform we compare against. Business is 350 prompts across four models, 42,000 answers a month at $579, about £426, which is about a penny each.

We do not publish an answer cap, but the same arithmetic works from the published plan. Business tracks 200 prompts across 4 engines daily, which is 24,000 answers a month at £349, or about 1.5p an answer.

So Promptwatch is better value per answer at both ends of its published range, and we are not going to argue otherwise. At entry it is not close: Pro is 50 prompts across 2 engines at £149. If your question is purely how many answers a pound buys, Essential wins that comparison and you should buy it.

The reason most teams do not stop there is the second half of the invoice. What you do with a gap is where the money actually goes, and that is the next two sections.

Our prices exclude VAT. We are not currently VAT registered, so nothing is added at checkout, and businesses can still enter a VAT number. The current tiers are on the pricing page.

Promptwatch publishes a roster of eight: ChatGPT, Perplexity, Google, Claude, Gemini, Meta, DeepSeek and Grok. Every tier tracks four of them. Moving from Essential to Professional to Business buys more prompts, more projects and more locations, but the model count stays at four throughout.

We publish Gemini, ChatGPT, Google AI Overviews, and Google AI Mode, with Microsoft Copilot, Perplexity, and Claude on Custom plans. Pro tracks 2 daily and Business tracks 4, all included in the tier price.

The practical difference for a UK brand is the Google AI surfaces, which sit on our published roster as two separately tracked surfaces rather than one line called Google. The practical difference the other way is Grok and DeepSeek, which Promptwatch offers and we do not. Decide that on your own audience rather than on the total count, because a longer roster you can only use four of is not the same as coverage.

There is a clear buyer for Promptwatch and it is not a small one.

You want the article, not the brief. Professional includes five generated AEO articles a month and Business includes ten, written from an analysis of the sources the engines cite. If you have no writer, no agency and no capacity, a draft on the page today genuinely beats a brief that sits in a queue. That is a real argument and it decides a lot of purchases.

You are starting out and price is the constraint. Essential at $95 a month for 50 prompts across four models, with API and MCP access included and a 7-day trial, is one of the most accessible serious entry points in the category. Most platforms put developer access three tiers up.

You need sub-country location data. Business adds state and city level tracking alongside shopping insights and ads reporting. If you are a multi-site retailer and the question is how answers differ between Manchester and Bristol, that is a capability our published plans do not offer.

You want to know how the data is collected. Promptwatch states plainly that it collects by reading the interfaces of the AI tools people actually use. Whether that method suits you is your call, but publishing it at all puts Promptwatch ahead of most of this category, and it is the right question to ask every vendor you shortlist.

Answyn is for the team that has to defend the number and then act on it.

Briefs, not generated articles, and that is deliberate. We hand you a writing brief and a technical brief built from your own collected answers: the page to improve, the structure that helps an engine extract a clear answer, the proof points the current answers are missing, and the schema to implement. A brief goes to your writer, your agency or your subject matter expert, and a human is accountable for the claim. The questions that decide whether an estate compounds or quietly rots are who reviews the pages for accuracy, who updates them when a price moves, and whose name is on it if it is wrong. Those questions do not come up in a demo of a generator. We have set out the full reasoning on the briefs page.

The customer journey map finds the turn where you lose the customer. Buyers describe a problem, ask for options, compare named brands, then validate a favourite. We classify your tracked questions into those stages and show visibility at each one, so you can see exactly where a competitor takes your place instead of reading one average across the set. The customer journey page shows the view, and our handbook piece on customer journey analysis in AI search sets out the evidence.

Five metrics and no composite score. Visibility, prominence, share of voice, sentiment and citation share are reported separately, and each one opens back to the full answer text and the citations the engine used. A blended score can move several points on the same underlying data purely because the vendor changed the formula, and you would have no way to tell. If a number cannot be opened, it is not shown.

10 brands on one subscription. Business covers 10 brands and 25 pinned competitors at £349 a month, which is £34.90 per brand per month. Promptwatch Business covers five projects at about £426. For an agency or a group with several trading names that is the difference between one invoice and two.

The commercial terms are British. A UK-registered company, prices published and billed in pounds with no conversion at checkout, ICO registration, and the United Kingdom as the default tracking market rather than a country setting you configure and forget. No FX line on the monthly statement and no cross-border card fee.

Where we are narrower, plainly: Promptwatch tracks more prompts at the top of its published range and publishes an answer cap that we do not. Promptwatch includes API access at entry where we put the API on Custom. Our published plans track the United Kingdom, so multiple markets are a Custom conversation and sub-country tracking is not offered. History runs three months on Pro and twelve on Business.

When a brief becomes a published page, we keep that URL in the record and report two things separately: whether engines started citing the page, and whether the brand gets named in the answers it appears in. A page cited with no mention of the brand is not a win, and a platform that blends both into a single score will not tell you which one you have got.

LLM Analytics then shows which AI crawlers reached the page and whether real people arrived on it from an AI assistant. That matters most where articles are produced at volume, because ten pages a month is only progress if you can say which of them earned a citation and which brought a visit. We hold the whole chain in one record, from the gap, to the brief, to the page, to the citations and the visits. You read it on the published pages view.

Answer one question honestly: when the platform shows you a gap next month, who writes the page?

If the answer is nobody, and the realistic alternative is that nothing gets published at all, buy the generator. Something beats nothing and we will not pretend otherwise.

If the answer is a person, in-house or at your agency, then a brief is the artefact that person needs and a generated draft is a thing they will rewrite anyway.

After that, three quick checks.

1. Which surfaces do you actually need watched, the Google AI surfaces or Grok and DeepSeek?
2. Do you need more than one country, or sub-country data, on a published plan?
3. Is a dollar or euro price acceptable to your budget holder, or does the FX line become a monthly conversation?
