Straight answers about Assay, grounded in our own Truth Graph. Not a generic model's best guess.
Writer keeps you on-voice. Assay keeps you on-truth.
Writer is brand memory, and it's genuinely good at it. Assay is on-truth. On-voice is table stakes now. Whether the on-brand sentence is still correct is the actual job.
"Our team plan is just $79/seat, built for how modern teams actually work."
Credit where it's due
We're not here to run it down. If you want your company to sound like one voice across a thousand writers, Writer is a serious answer. Three things it genuinely gets right.
A real style engine. It keeps tone, terminology, and phrasing consistent across teams and volume, which is genuinely hard.
It remembers how you say things, your lexicon and guardrails, and applies them everywhere writing happens.
Mature integrations and controls for large writing orgs. If voice consistency is the problem, it's a strong pick.
If we've got a fact about Writer wrong, tell us and we'll fix it. This page is only worth anything if it's fair.
The one axis that matters
Voice is the layer everyone can see. Truth is the layer that gets you in trouble. A perfectly on-brand sentence can still be wrong, and a voice engine has no way to know.
Change the price once and every surface re-renders. A voice tool keeps the wrong number beautifully phrased.
The version proven to win by real reply data, not just the version that sounds most like you.
Every claim reviewed against your approved truth, with a receipt. Voice engines don't have a veto.
An honest call
Your problem is voice. You have many writers and you need everything to sound like one company, with mature controls over tone and terminology. That's the job Writer was built for, and it does it well.
Your problem is truth. Your prices, features, and positioning move, and you need every surface and every AI to stay current, correct, and approved, with a governed veto and a receipt. That's the job Assay was built for.
Plenty of teams run both: Writer for how it sounds, Assay for what it says. If you only fix one this year, fix the one that misquotes your price.
The fair test
Forget the feature grid. Run the governed audit against your public surfaces and see how much of your own published truth already argues with itself. Read-only, free, yours to keep.
Not exactly. Writer governs how your work sounds; Assay governs what it says, whether the claim is current, correct, and approved. Some teams run both. If you only fix one thing this year, fix the one that misquotes your price.
No. On-voice is table stakes now. The harder job is whether the on-brand sentence is true. A deck can quote last week's price in flawless brand English, and every AI that reads it repeats it. Voice consistency won't catch that. A truth check will.
Look at your own site. Run the governed AI-visibility audit against your public surfaces and see how much of your published truth already contradicts itself. Read-only, free, and yours to keep.
