Overview
Right-click any text to check it against your brand voice guide and marketing-claims rules, then refresh it on-brand.
Check any text against your brand voice and marketing-claims compliance without leaving the page you're writing on. Highlight a sentence, a paragraph, or a whole draft, right-click, and pick a check. Results appear in a panel on the page in seconds — no copying into another tab. START HERE — SET UP YOUR ACCOUNT FIRST This extension does not work on its own. Before you install it, create your account and build your brand voice profile at: https://davidiwanow.com/tools/brand-voice/brand-voice-survey.html Go to the link above and complete the brand voice survey for your domain. You can then create your account and generate the profile the extension scores against. Then pay to add credits to your account. Each onpage content check typically costs one credit using the Chrome extension. Once you have an account you can connect it to your account in one click — no API keys to copy or paste. Without a completed brand profile and available credits, the extension has nothing to check your copy against. BRAND VOICE CHECK Scores your copy 0–100 against the brand voice profile you built at davidiwanow.com, with an A–E band, tone and language match, and readability. Off-brand phrases are quoted back with a specific rewrite for each one. Scoring is arithmetic, not a model's gut feel: the engine measures where your content sits on ten calibrated language dimensions and compares that to your agreed profile. COMPLIANCE CHECK Screens marketing copy for claims, promises, guarantees and other regulated language across EU, UK, Ireland and US rules, or all of them at once. Every flag names the rule, the risk, the team that should review it, and a defensible rewrite. Severity is enforced by rule, not guessed, so the verdict can never contradict the flags. BUILT FOR DRAFTING Works on any page, including LinkedIn, Google Docs and your own CMS Flagged phrases are highlighted directly on the page and numbered One click copies a rewritten version with the suggested fixes applied Whole-page scans for auditing a live page or a competitor's Choose target markets and B2C or B2B per check ACCOUNT AND CREDITS REQUIRED This extension is a companion to the Brand Voice Generator — it is not a standalone tool. Set up your account and profile first at https://davidiwanow.com/tools/brand-voice/brand-voice-survey.html, then connect the extension. Selected text is sent to davidiwanow.com to be analysed. Nothing else is collected, and no data is sold or shared. Compliance output is an advisory pre-screen, not legal advice. It does not replace review by your legal or regulatory team.
