Overview

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returns $36 for every $1", or a whole paragraph of copy, and GroundedKit returns: - a verdict: verified, misquoted, outdated or unsourced - the primary source, with what it actually says (exact quote, method, sample and date) - how the number drifted as it was repeated - a safe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. No account, no API key, no tracking. Data is licensed CC BY 4.0 and also available as JSON and CSV. GroundedKit is a project of Organic Media Buying, LLC.

Tools

check_stat

Claude
Paste a marketing or influencer-marketing statistic (a sentence or a whole paragraph), or ask for a reference number (e.g. 'what share of US adults use TikTok'). Returns the best-matching checked claim with its verdict, confidence, primary source, what the source actually says, a safe rephrasing and the claim URL, plus its kind (stat_check or reference_fact), as_of date, last_checked date and stale flag (last checked more than 180 days ago), and close alternatives. Returns match: none when the stat is not in the database.

get_claim

Claude
Full record for one checked claim by id (slug) or claim page URL: verdict, confidence, origin, exact quote, method and sample, drift, publisher interest, safe rephrasing and every source we opened.

list_verdicts

Claude
The four verdicts (verified, misquoted, outdated, unsourced) with definitions and how many claims carry each, plus confidence levels and dataset info.

search_claims

Claude
Keyword search over all checked marketing statistics (claim text, common phrasing, origin publisher). Optionally filter by verdict. Returns short summaries; get_claim returns the full record for an id.

verify_text

Claude
Paste a whole draft (up to 20,000 characters: a blog post, deck notes, an email, a social caption). Splits it into sentences, keeps each sentence that contains a number or statistic, and matches each one against the checked claims. Returns one row per statement with the numbers found, the match level, verdict, safe rephrasing and claim URL, or status not_in_database, plus counts by status and verdict. Unmatched statistic text is logged anonymously (date and text only) to guide which stats get checked next.
