Promptwatch vs ChatSEO 2026
The platform we run client GEO on versus a Search Console chat with a GEO agent. What we would buy, what we would not replace.
We get this comparison when a French-speaking founder already likes ChatSEO and asks why our retainers still include Promptwatch. Short answer: ChatSEO helps us (or them) work Google. Promptwatch is how we measure AI search. We use Promptwatch on client programs. We do not treat ChatSEO's GEO agent as that program.
How we compared them this week
ChatSEO site pulled 28 August 2026 (pricing, about, features, llms.txt). Promptwatch from the sheet we already trust (llms.txt 23 August 2026). We did not borrow ChatSEO's in-house 4.9/5 or their GSC screenshots as our proof.
ChatSEO people: Dulait, Vengeons, Leducq. GSC chat, CMS publish after approval, MCP on Pro. Promptwatch: prompts, citations, crawler logs, visitor conversions, Content Agents.
What we would put in a client deck
| Question the client asks | What we answer |
|---|---|
| Who writes the WordPress title? | ChatSEO can, after approve. We can too. Promptwatch Content Agents are Webflow/Framer today. |
| Who knows if ChatGPT cited the page? | Promptwatch. ChatSEO did not publish an engine/prompt SKU. |
| Who sees GPTBot in logs? | Promptwatch Agent Analytics. Not on the ChatSEO listing. |
| Who ties an AI visit to a conversion? | Promptwatch visitor analytics. ChatSEO Pro is GA for Google. |
| What is the cheap seat? | ChatSEO Starter from €29 excl. VAT. Promptwatch Explore is $0. Essential is $95. |
ChatSEO Pro from €49 (MCP, 3 sites). Ranker from €79 (10 sites). Annual -20%. Free-prompt text fights 10-then-3 versus 5. Credit definition fights 1:1 versus variable. Stack-replacement homepage versus modest FAQ. We show the fight. We do not pick a silent winner for them.
Promptwatch Professional $245 if they need 25M crawler logs. Agency Kick-off $199 if they are us-shaped. G2 4.7/5, 1,840-plus customers. No $29 Promptwatch plan. Clients mix that with ChatSEO's €29. We stop that sentence on the call.
What we would actually buy
For a client already on WordPress who wants cheaper on-page labor: we might let them keep ChatSEO Starter and we still bill Promptwatch. Their writer is not our citation source.
For a client who only has ChatSEO today: we add Promptwatch Explore the same week, then Essential when the sample is too small. We do not wait for ChatSEO to grow a tracker. Their FAQ still says you apply the actions. Fine. We still need a system of record for AI answers.
For us internally: Promptwatch stays. ChatSEO is optional for GSC triage on a property that is not worth another Semrush seat. We would not report GEO share of voice from ChatSEO credits.
Vendor ChatSEO numbers (10,000+ sites, 130,000+ analyses, Tabary / BRD / Hyatt GSC stories) stay in their column. Our column is crawler logs and conversions from Promptwatch.
The recommendation we give
If the founder is choosing one tool because GEO was in both headlines, choose Promptwatch. If they already like ChatSEO for Google, keep it and add Promptwatch. Do not cancel the platform we run because an agent list said "get cited by AI."
That is the comparison we will sign. ChatSEO is a useful GSC employee. Promptwatch remains the measurement answer on our accounts.
