◇ Assay vs Writer

Writer keeps you on-voice. Assay keeps you on-truth.

Same words. One of them checks if they're true.

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.

Credit where it's due

Writer is very good at what it does.

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.

✎

Brand voice at scale

A real style engine. It keeps tone, terminology, and phrasing consistent across teams and volume, which is genuinely hard.

◫

Brand memory

It remembers how you say things, your lexicon and guardrails, and applies them everywhere writing happens.

⧉

Enterprise writing workflows

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

Writer governs how work sounds. Assay governs what work says.

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.

"Get the whole team on board for just $79/seat, the way modern teams actually work."
✓ On-voice ✕ Off-truth · price changed Tuesday
Your price changed on Tuesday. This deck still quotes Monday's number in flawless brand English, and every AI that reads it repeats the wrong number. Voice consistency can't catch this. The firewall catches it before it ships and cites the source.
✓Living

Work that never goes dead.

Change the approved price and the graph finds every surface built on it, with the fix ready. A voice tool keeps the wrong number beautifully phrased.

✓Winning

The version winning in your market.

Reply data flows back to the exact claim that earned it, and the winner becomes the version everything runs on. A voice engine can only tell you which one sounds like you.

✓Governed

A firewall before it ships.

Claims that contradict approved truth get caught at the gate. Wrong facts already out get found and corrected. Every catch is logged, and voice engines don't have a veto.

An honest call

When to pick which.

Choose Writer if

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.

Choose Assay if

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.

The fair test

The fastest way to compare is to look at your own site.

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.

Is Assay a replacement for Writer? +

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.

Isn't on-voice consistency the same as accuracy? +

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.
