What ReachLLM is, and who it is for
An agency with its own software. ReachLLM calls itself an AI-native GEO agency plus visibility software. It tests how AI systems describe a business, maps the sources behind the answers, and executes an optimization plan.[2]
Two ways to buy. Pro and Scale are self-serve software plans for teams running AI visibility in-house, with white-label reports on Scale. Growth is a managed service where a dedicated GEO expert executes the roadmap.[1]
Proofsource is an AI intelligence platform that shows which buyer questions name your brand in ChatGPT, Perplexity, Claude and Google AI Overviews, who gets named instead, and exactly what to fix.

Where each shines
Both tools are built well for different teams. Each point is a strength, read from that vendor's own pages.
Where ReachLLM shines
- A done-for-you option. Growth adds a dedicated GEO expert who executes content, schema and PR work, for teams without the hands to act on findings.[1]
- Built for agency resale. Scale includes white-label reports and client-ready share links across up to 10 projects.[1]
- Gemini on every software plan. Gemini is one of the four models included on Pro and Scale.[1]
Where Proofsource shines
- Claude from the trial up. Claude is in the Proofsource panel on the trial and by default on every plan. ReachLLM sells Claude as an add-on.[1]
- A free start, no card. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. ReachLLM's software starts with a 14-day trial of a paid plan.[1]
- Intervals on every number. Proofsource publishes a 95% Wilson interval with every score and holds alerts until a change clears it. ReachLLM's pricing page does not describe how it handles run-to-run variation.
- Measurement separate from execution. When the same vendor does the work and reports on it, an independent reading is the check. Each Proofsource gap names the pages the engine cited instead of you, with a draft fix you approve.
Proofsource or ReachLLM: the fair verdict
ReachLLM suits a team that wants an agency to execute GEO work and software to watch it, under one vendor.
Proofsource suits a team that wants the measurement independent of whoever does the work: readings as often as daily, with intervals, each gap tied to the pages the engine cited instead, and a draft fix you approve.
