Which AI Sent vs Promptwatch: visibility tracking or lead attribution?

Summary

Choose Promptwatch if your main question is “do AI models mention us, and how do we get mentioned more?”. It tracks 50 to 350 prompts across more than ten AI models, shows which sources they cite, and on higher plans writes content to close the gaps. It starts at $95 a month. Choose Which AI Sent if your main question is “which customers did AI send us, and what were they worth?”. It follows AI visitors to named leads, bookings and sales, and asks every customer how they found you, so it also counts people who asked ChatGPT and then phoned. It has a free plan; paid plans start at $20 a month.

The two tools sit at different ends of the same funnel, which is why some teams use both. If you are choosing one, start with the question you need to answer for your boss or your client.

Side by side

	Promptwatch	Which AI Sent
Main job	AI visibility: whether AI models mention and cite your brand for chosen prompts	AI search attribution: the visits, leads and revenue AI sends you
AI models covered	More: ChatGPT, Google AI Overviews and AI Mode, Gemini, Perplexity, Claude, Copilot, Meta AI, DeepSeek, Mistral and others, on every plan	Visits from ChatGPT, Gemini, Perplexity, Claude and Copilot (plus Meta AI, Grok, DeepSeek and more); weekly check of whether ChatGPT recommends you
Prompt tracking	50 prompts (Essential) to 350 (Business)	A weekly visibility check, not a large prompt index
AI visitors on your site	Visitor Analytics script (via Google Tag Manager or the site header) and AI crawler logs	One-click install on WordPress, Wix and Google Tag Manager, one line of code elsewhere
Ties a visit to a named lead or booking	Conversion tracking is listed; its pricing page doesn’t describe lead-level records	Yes: every lead kept with its AI source and the pages it read
Customers who never clicked (phoned or searched your name)	Not covered: it works from prompts and tracked visits	Yes: a “How did you first hear about us?” question on forms and calls
Evidence label per lead	No	Confirmed, Declared or Assisted
Content writing	Yes on Professional and above, based on the sources AI cites	No. Site audit, llms.txt maker and business-details (schema) tools instead
CRM sync	API and MCP access; no CRM list on the pricing page	HubSpot, GoHighLevel, SmartMoving, Zapier, Make, webhooks and CSV import (Pro)
Free plan	No public free plan; free trial on Essential and Professional	Yes: one website, AI traffic, no card
Paid plans	Essential $95/month, Professional $245/month, Business $579/month, Enterprise custom	Starter $20/month, Pro $50/month, Agency $100/month

Where Promptwatch is the better tool

• You need to track many prompts across many AI models. Promptwatch covers Google AI Overviews, AI Mode, Gemini, Perplexity, Claude and more on every plan. Our check only looks at ChatGPT each week.
• You want to see which sources AI cites, and fix the gaps. Citation and source data plus content writing are its core. We don’t write content.
• You report share of voice against competitors. That is what prompt tracking is built for.
• You care about AI crawlers. Its crawler logs show which AI bots read which pages.

Where Which AI Sent is the better tool

• You need to prove AI brings customers, not just mentions. A mention is not a sale. We keep each AI lead with its source, its pages and its value (see AI lead attribution).
• Your customers call, book or ask for a quote. Service businesses, trades and clinics are paid after a conversation. Only asking customers how they found you catches the ones who never clicked (why every tool undercounts).
• You run an agency. The Agency plan covers 10 websites, with a private, view-only dashboard per client, for $100 a month.
• Budget matters. The free plan has no time limit, and Pro is $50 a month against $95 for Promptwatch’s entry plan.
