Proofsource review: pricing, features & alternatives

proofsource.co/pricing (read 20 October 2026). Every brand pays a cadence fee, $28 a month for daily or $7 for weekly, plus a per-question price on each engine you choose. Claude costs more per question because, the page says, it searches the web and reads about 14k words per answer. Questions above 50 per brand are 20% off. The cheapest setup, 5 weekly questions on ChatGPT, comes to $9 a month.

Agencies get a free workspace with unlimited clients, client logins and white-label reports; each client brand is priced on the same card, and an agency keeps 80% of any markup it charges. Managed, where Proofsource's team runs the program on all 10 engines, starts at $1,000 a month.

proofsource.co/features/ai-traffic (read 20 October 2026). Connect a Cloudflare zone with one click or an API token, or send access logs as a log drain. Proofsource counts daily requests from GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot and others, checks each against published IP ranges or reverse DNS, and records response times. Pages are then shown as crawled and cited, crawled but never cited, or cited but rarely crawled.

Search Console connects in the app. GA4 is read with Viewer access and set up with the team on a call, which then reports AI-referred sessions, conversions and revenue by platform.

Every row below is a capability we already listed for Proofsource. It is the published feature set for this page, not a guess at an unpublished demo. Compare it with the Promptwatch checklist that follows.

On this listing, Proofsource is a AI visibility platform for Small brands and agencies that want to pay only for the questions and engines they track, and like seeing error bars on every number. What we sourced here: Mention rate, share of voice and position per engine, each with a 95% Wilson confidence interval; Self-serve engines: ChatGPT, Perplexity, Claude and Google AI Overviews, priced per question; Cited pages and domains, listicles that leave you out, and review-site ratings; Wrong-fact detection with the likely source page; AI Traffic: verified AI crawler requests per bot and page from Cloudflare or a log drain, crawled-versus-cited pages, and GA4 referrals and conversions.

If you buy Proofsource for the job above, plan a second tool (or Promptwatch) for the layers this listing does not document. Still missing here: Content Agents that plan, write, and publish GEO pages to a CMS with a review inbox; Citation analytics at page, domain, Reddit, YouTube, and offsite level; Prompt volumes, difficulty, query fan-outs, personas, city-level geo; Prompt and citation trends (what changed between checks); ChatGPT Shopping tracking and Ads Radar; Agent Chat, Unified Actions, MCP server / REST API on paid plans. Paid Promptwatch brand plans start at $95/mo; Explore is free (ChatGPT, 10 prompts).

Proofsource's public pages (and this listing) describe a narrower job than Promptwatch. Most rivals answer whether you were mentioned. Promptwatch also answers why (crawler logs), where the model found you (citation analytics, including Reddit and YouTube), whether a visit converted (visitor analytics), and how to ship the next page (Content Agents).

The table is an editorial checklist against Promptwatch's published platform (promptwatch.com/llms.txt, 2026-08-23). It is not a hidden feature list for this vendor. 'Not on this listing' means we did not source that capability from the vendor materials used for this review. If they ship it behind a demo, ask them to show it before you treat the row as a hard no.
