GroundedKit

GroundedKit is a free, read-only database of widely repeated US marketing and influencer-marketing statistics, each traced back to the organization that first published it.

Paste a stat like "92% of consumers trust influencers" or "email marketing returns $36 for every $1", or a whole paragraph of copy, and GroundedKit returns:

• a verdict: verified, misquoted, outdated or unsourced
• the primary source, with what it actually says (exact quote, method, sample and date)
• how the number drifted as it was repeated
• a safe rephrasing you can publish, plus a citable claim page URL

Tools:

• check_stat: match a statistic (or a paragraph) to a checked claim
• search_claims: keyword search across all claims, optionally filtered by verdict
• get_claim: the full record for one claim, with every source opened
• list_verdicts: verdict definitions, counts and dataset info
• verify_text: paste a whole paragraph or draft and get every stat in it checked at once

Useful for marketers, agencies, content writers, PR teams and analysts who want to check a number before it goes into a deck, blog post, pitch or ad. A verdict describes how a number is sourced and quoted, not whether the underlying idea is true. If a stat isn't in the database, the tool says so plainly instead of guessing.
