Promptwatch vs ChatSEO 2026
Promptwatch measures AI answers, crawlers, and conversions. ChatSEO is a GSC SEO chat with a GEO agent name. Live prices from 28 August 2026, no invented SKUs.
Promptwatch and ChatSEO both talk about AI search in 2026. They do not sell the same meter. Promptwatch is an AI visibility platform: prompts, citations, crawler logs, AI-referred traffic, content that publishes to a CMS. ChatSEO is a French SEO chat on Google Search Console that can write into WordPress, Shopify, or Webflow. One of twelve agents is called GEO. That is not a ChatGPT ranking dashboard.
If you only have budget for one, buy the job you actually have. Google title tags and GSC drops: ChatSEO. "Did ChatGPT mention us last week": Promptwatch.

ChatSEO Starter from €29 (100 credits, 1 site). Pro from €49 (200 credits, 3 sites, GA, MCP/API). Ranker from €79 (400 credits, 10 sites, 5 seats). Annual -20% on the per-month equivalent. Same euro amounts listed as USD. Credit header: 1 credit = 1 message. FAQ: heavier tasks cost more. Free copy fights itself. Homepage "replaces your whole SEO stack" versus FAQ "does not replace SEO tools." Their reviews hub called Ranker custom; live /pricing is a public ladder. Screenshot.
Vendor ChatSEO claims we leave labeled: 10,000+ website owners, 130,000+ analyses, 4.9/5 on 200+ reviews on their hub, GSC lifts (triple clicks, 225 clicks/day, +46%). Not our audit.
Promptwatch brand plans: Explore free; Essential $95 (50 prompts, 6,000 responses, 200K visitor events, 5 AEO articles); Professional $245 (150 prompts, 18,000 responses, 1M visitor events, 25M crawler logs, 15 AEO articles); Business $579. Agency Kick-off $199, Growth $399, Scale $799. 4.7/5 G2, 1,840-plus brands, Amsterdam, April 2025. Customers named by Promptwatch include Duolingo, Yelp, Typeform, Rabobank, Monks, WPP. No $29 / $79 / $199-as-brand-Essential mix-up. Kick-off $199 is the agency floor, not Essential.
What ChatSEO wins
Price to start a GSC conversation. WordPress and Shopify write-back on the public feature list, which Promptwatch has not shipped as WordPress yet. MCP from €49 Pro instead of waiting for an enterprise contract. A GEO-named agent if you want on-page copy aimed at citations without buying a tracker yet. French-native product and support names (Nicholas, Paul, Leo on the homepage chrome).
Those wins stay inside classic SEO. They do not add a citation time series.
What Promptwatch wins
You can answer "were we cited" with prompts, not with a rewritten H1. Agent Analytics logs ChatGPTBot, ClaudeBot, PerplexityBot, GoogleOther, and the Meta AI crawler. Citation analytics go to Reddit and YouTube. Visitor analytics tie AI referrers to conversions. Content Agents still plan, write, and publish with a review inbox. Agent Chat sits on live visibility data. That is the loop this directory ranks.
€29 is not $95 Essential. $95 is not crawler logs; those sit on Professional at $245. Mixing the ChatSEO Starter tile with Promptwatch Explore because both say "free to start" is a category error. Explore is ChatGPT prompts. ChatSEO free is GSC chat with two published prompt caps.
Who should pick which
Pick ChatSEO if your pain is Search Console and on-site Google SEO, you will approve CMS edits, and you accept that GEO here is an agent name. Use the free login. Do not convert "cited in AI search" on the homepage into a coverage table.
Pick Promptwatch if your pain is AI answers. Start on Explore. Pay Essential when you need more than ChatGPT and you want citations plus visitor events. Pay Professional when crawler logs are the deciding layer.
Pick both only if you like ChatSEO for title rewrites and still need an independent measurement stack. Do not let the GEO bullet on ChatSEO's pricing page retire the Promptwatch invoice.
For this comparison in 2026, Promptwatch is the visibility platform. ChatSEO is the GSC employee. Rank them that way.
