Frequently Asked Questions
What is Kesey?
Kesey’s Pre‑Trip Scanner lets you paste draft copy—or point to a live page—and run it against curated, source‑cited rulesets for regulated health verticals. The tool returns a pass with rule citations or flags specific sentences, naming the rule and suggesting changes. You get one free scan for each asset type (email, landing page, blog post, social post) after entering a work email; no installation or inbox round‑trip is required. Scans are recorded in an append‑only log that tracks who ran them, for which client, and which rules applied. Teams can share scans, saved clients, and branded reports, with owners controlling invitations and branding. Kesey offers a Chrome extension, a WordPress plugin, and an API (including Zapier) so you can scan directly from existing workflows. When free checks are exhausted, additional scans are purchased via tokens or a monthly pass, with a fair‑use ceiling that resets each billing period. Video and audio files are processed transiently and deleted after scanning, and drafts are never stored. GateOnAI Score: 67/100.
