If This Sounds Familiar

Your AI Content Has a Problem

Not a technical problem. A brand problem. If any of these hit close to home, Sentinel was built for you.

01

Your AI content sounds like everyone else's


It’s technically correct but completely generic. No personality, no voice, nothing that sounds like your company. So you rewrite it. Which defeats the whole point.

02

Every piece of content sounds different

Your blogs are formal. LinkedIn posts are casual. Your marketing email sounds like it came from a different business entirely. There is no consistency.

03

The sales team's posts make you wince

Salesy. Shouty. Off-message. You either spend time rewriting their content for them or you can’t get them to post at all. Either way, this significant amplification opportunity goes untapped.

Meet Sentinel

Set Your Standard. Sentinel Holds It.

Sentinel is an AI brand intelligence and governance system built for B2B technology companies. It is the intelligence layer that sits underneath the AI tool your team already uses.

Sentinel captures your brand voice, your messaging, your audience’s pain points, and your rules. It combines them with its own proprietary strict anti-AI writing protocols to ensure everything you write with AI sounds like you.

Unlike other AI writing tools, Sentinel was built by an experienced team of B2B marketers. Expert copywriters, social media managers, SEO/GEO specialists and digital marketing pros. All these years of experience are included in over 900 data points that Sentinel uses to combine everything about your brand with expert knowledge from our team. 

 
1

Configure

Answer a structured set of questions through the Sentinel Configurator: brand, tone, audience, messaging, keywords, and things your company must always and must never say. If you don’t have any of this documented, Sentinel reviews your website and uses its intelligence to create this for you. You can then review and amend its output so you’re always in full control.

2

Install

Your Sentinel brand intelligence layer is delivered as a set of structured files. Simply follow the setup instructions for ChatGPT, Claude, Gemini, Copilot, or any AI model that accepts a knowledge upload, and you’re ready to go. All in less time than it takes to make a cup of coffee. We’ll even walk you through it if you need help.

3

Create

Once installed, Sentinel ensures every piece of content your AI creates comes out sounding like your company. Save time  briefing, rebriefing and prompting your AI, all while wondering if it would have been quicker to write it yourself. Become the human in the loop who reviews the content created and makes minor refinements. Save time and get better content.

What Clients Say

Built for B2B Tech. Proven in Practice.

I was using AI to help create our content but it never seemed to come out right. Instead of helping me it was almost taking longer. The difference with Sentinel was immediate. I am now able to create really good content quickly and it’s always on brand. I wear a lot of hats in my job and this is a lifesaver.

Incentivizer

I create regular content for our website and was worried that I’d start repeating myself on our blogs. Sentinel has this clever ‘do not repeat’ logic which ensures I don’t create similar content. It’s helping me create better blogs and web pages and it’s so much faster.

What Is Inside

six Layers of Brand Intelligence

Everything your AI needs to write like you, built from over 900 data points, across over 35 proprietary knowledge components that make up Sentinel’s six core modules. Together, they give your AI a complete picture of who you are, what you do, and how you communicate with guardrails to ensure your content never sounds like AI.

01

Company Foundations

The non-negotionable core

Your mission, vision, and values aren’t marketing assets, they’re the rules everything else is built on. This layer captures the why that defines your business. Why it exists and how it behaves, providing a fixed reference point that keeps every team, campaign, and decision aligned.

02

Brand Identity

Your brand, your way

Tone of voice, messaging pillars, personality, and positioning, all configured to reflect your specific market, audience, and commercial goals. This layer is ensures your brand feels authentic while remaining strategically coherent across every touchpoint.

03

Brand Standards

Consistency you can count on

The rules that govern how your brand looks, sounds, and shows up; consistently, every time. This layer sets the fixed standards that protect quality and recognition, removing ambiguity for anyone creating content in your business or on your behalf.

04

Brand Protection

The guardrails that don't move

Some things are simply not up for debate. This layer defines what your brand will never do, say, or be associated with; the ethical and reputational guardrails that sit above all other considerations. Any regulatory or compliance statements that have to be used. It’s backed by Sentinel’s ever evolving anti-AI writing guardian that prevents AI slop. Non-negotiable by design, this layer protects your brand’s integrity in every context.

05

Data & Insights

data-led Intelligence

This layer uses insights you provide as part of your Sentinel Configuration to inform content decisions. These can include Google Analytics reports, SEO reports and competitor analysis, client-specific performance data, audience intelligence, and market context. This is captured and structured by Sentinel so that your content decisions are always data-led to ensure the very best output rather than generic AI waffle.

06

AI & Search

content that gets found

Search engines and AI platforms don’t just crawl your content, they interpret it. This layer ensures your brand is structured, signalled, and optimised so it surfaces in the right results and gets extracted accurately by AI-powered tools. From keyword intelligence to AI-readiness, Sentinel makes your brand as visible to machines as it is compelling to people.

Sentinel Skills

One Voice. OPTIMISED FOR Every Channel. No Exceptions.

Sentinel Skills are specific modules for your Sentinel that have been created by marketing specialists that enable you to create highly effective content with your Sentinel for specific use cases. Each one produces output consistent with your brand voice and aligned to best practices for that specific content type. No more briefing your AI on the all important ‘hook’ for your LinkedIn post, with Sentinel Skills that’s built in.

Blogging

Blog content built on your brand foundation, not generic templates. Each post is structured for SEO / GEO, written to reflect your tone and expertise. Written to serve both human readers and AI-powered search, blogs created with this skill work harder for longer.

Email Newsletter

Newsletters that sound like you, land on time, and give your subscribers genuine value. Built around your messaging pillars and audience intelligence, this skill ensures every send strengthens the relationship, without eating up hours of editorial time.

LinkedIn Posting

Short-form LinkedIn post that cut through the noise and get read. Posts are crafted to reflect your brand’s personality, spark conversation, and stay firmly within your brand guardrails. This skill is ideal for sales people who want to post  but don’t have the confidence.

LinkedIn ARticle

Long-form LinkedIn articles that position you as the expert your audience already suspects you are. Structured for authority and readability, these pieces draw on your brand standards and data insights to make a credible, compelling article your audience will want to read.

Web & Pages

Website and landing page copy that converts without compromising your brand. Built around your messaging, audience intent, and funnel stage, this skill ensures every page speaks to the right person at the right moment, with the SEO and AI visibility signals built in from the start.

Print Copy

Print collateral that works with the format, not against it. From brochures and direct mail to exhibition panels and sell sheets, this skill governs copy for every print format based on how your audience actually reads it, with built-in handoff instructions so nothing gets lost between copy and design.

More Sentinel Skills coming. Each one extends your brand governance into new marketing channels.

Questions Worth Asking

frequently asked questions

Does it work with the AI tool we already use?

Sentinel is tool-agnostic. It works with ChatGPT, Claude, Gemini, Microsoft Copilot, or any tool that accepts a system prompt or knowledge upload. You are not locked in, and you will not need to reconfigure if you switch AI tools.

Most businesses complete the Sentinel Configurator in an hour. It can pre-populate answers from your website as a starting point. You review, refine, and add the specifics. Once built, installation into your AI tool takes less than an hour too.

You could. But it would take a very long time. Sentinel is powered by over 900 data points, and that is constantly growing. It took over a month to build. Most people don’t have the time or AI experience to create something like this, let alone keep it updated with the constant AI changes. With Sentinel, they don’t need to. 

Updates are handled as part of your quarterly or monthly review. Sentinel is designed to evolve with your business. New products, new messaging, rebrand. Simply update your Sentinel! 

Yes. The Content Governance component is specifically designed to capture the compliance rules that listed companies need: what can and cannot be stated publicly, how to reference financial performance, and how to handle market-sensitive topics. Raise this in your onboarding call and we will work through it with you.

No. Sentinel will work across all AI models, but for security purposes we recommend you have a paid version.
