Content that sounds like your brand.

ContentEngine is an AI content system that FieldSignal builds and installs for your organization. It turns one approved Knowledge Stack (your positioning, audiences, offers, proof and rules) into working skills for social, blog, email and campaign planning, with a Brand QA check in front of anything published.

It runs inside the AI tools your team already uses: Claude, ChatGPT or any MCP client.

A general-purpose assistant knows the internet. It doesn’t know your brand. ContentEngine gives it your approved knowledge, your voice and your rules, then tests it before your team relies on it.

The result sounds like you on the first draft. When it doesn’t know something, it says so instead of filling the gap.

Claude as a plugin, ChatGPT as a Custom GPT, and any MCP client, including OpsEngine. You choose the platforms at kickoff, and only those get built and tested.

Eight steps with four sign-off gates: a fit check and kickoff, a first look with three sample posts, an intake check (ten questions at most, Gate 1), building the Knowledge Stack, a second reviewer’s Stack QA (Gate 2), an Engine Review where your approver signs off and the engine locks at version 1.0 (Gate 3), building and testing on each platform to 90% or better with no failed trap tests (Gate 4), then recorded training and handoff with two weeks of hypercare.

Roughly six hours for your main contact, three hours for your approver and about two and a half hours per creator. Most of that is reviewing drafts we’ve already prepared, plus recorded training.

Changes go through the master. We update it, validate it, rebuild, retest the affected tests and every trap test, then redeploy. Bigger changes, like a new offer, a new audience or a rewrite of your voice, get a fresh Engine Review before they go live.

It’s built not to. The engine writes only from approved knowledge, marks anything it can’t confirm as [NEEDS CONFIRMATION], and has to pass its trap tests before handoff. Brand QA and a human approval still sit in front of everything that gets published.

Yes. The Image Prompt add-on gives the engine a visual director for on-brand image prompts. Compliance packs for US FTC rules, Canada’s Competition Act, the EU AI Act and platform AI labels stay off unless you switch them on. They summarise public rules so the engine stays conservative; they aren’t legal advice.

Marketing teams that need more content than they have hands for and can’t let the brand slip: professional services firms, startups and tech companies, nonprofits, and in-house marketing teams at mid-sized and larger businesses.
