The near-miss that started everything
We were co-writing with a client. The draft reflected internal language. The audience wanted different words and different proof. We already had personas that captured pains, motivations and objections. The missing step was obvious. Test the draft against the personas before we send it for sign-off.
That is how Content Resonance Index began. GenAI made it achievable without long prompts or specialist operators. CRI is the fast, shared lens that moves teams from guessing to proving.
What CRI does in practice
Build personas once. Use AI mode to give you a persona in as little as two minutes, basic mode in about five minutes or advanced mode in about twenty to cover sixteen persona dimensions.
Paste your draft and select the relevant persona or personas.
Get a score in under eight seconds with ranked, specific recommendations tied to tone, pains, motivations and objections.
Fix the top two items, attach the scorecard to your sign-off note, and ship.
You still own the voice. CRI helps you write for someone, not just at them.
The internal pilot that changed our week
We started with our own social content being shipped for clients, because it is the most frequently rejected channel. With CRI in the loop, approved first time rose to over 98%. Meetings shortened, edits became targeted, and the calendar stopped slipping.
Where CRI helps most (hint hint, ICP Alignment)
Website and landing copy where clarity and confidence convert
Email sequences where one mis-pitched opener drags performance down
LinkedIn and social where tone and motivators need to match the segment
Blogs and guides where examples must mirror the reader’s world
Founders are finding it invaluable
Across sectors the reception has been strong, and founders who manage their own marketing have been particular champions. CRI gives them a fast way to test tone and message without six rounds of feedback.
