Does Compendium train AI on your data?
We don't reduce this to a yes/no — wording matters (defaults, opt-outs, enterprise carve-outs). Here is exactly what Compendium's privacy policy said when we captured it on 2026-10-31:
“We do not use Customer Data, booking-form answers, email lists or session recordings for these audiences, and we do not use personal information to train AI models.”
“These models are provided by the model providers listed below, under commercial terms that prohibit them from using Customer Data to train their models.”
“We do not use Customer Data to train AI models, whether ours or anyone else’s.”

Pricing & Cancellation Reality
Pricing is quote-only — no public amounts. Per their published terms: “The Website describes Snowstone, lets you book a demo, and lists ways to contact us, including about jobs.”.
Product reality
We check tools against public records, so this page covers Compendium's company, data, billing and reputation — not how well its output actually performs, which we haven't checked yet. To judge that, try the free tier if there is one and read recent hands-on reviews before committing to a paid plan.
