How Rheos Reads Your Website to Generate On-Brand Social Media Content
Rheos reads your website in under a minute, learns your brand voice, colours, audience, and themes, then drafts social posts, images, and carousels that sound and look like your business. Here's exactly how it works.
If you've ever pasted a prompt into ChatGPT and gotten back a caption that could belong to any business in the world, you already know the problem. Generic AI tools start every post from a blank page. Rheos starts every post from your business.
The way it does that is a one-minute website read at sign-up that builds a brand profile the AI then references for every piece of content you generate afterwards.
Brand Profile
•The structured snapshot Rheos builds from your website at sign-up: your business identity, brand voice, target audiences, content themes, colours, fonts, and logo. Every post Rheos drafts is grounded in this profile rather than written from scratch.Quick answer
| What | How long | What you get |
|---|---|---|
| Connect website | 30 seconds | Rheos crawls your homepage and key pages |
| Brand profile built | ~60 seconds | Identity, voice, audiences, themes, colours, fonts, logo |
| First post drafted | ~30 seconds after a prompt | On-brand text, image, carousel, or video — your choice |
| Edit anything | as much as you want | All extracted fields are editable before generation starts |
You go from URL to first publish-ready post in around three minutes for most small businesses.
How does Rheos analyse my website?
You give Rheos a URL during sign-up. It fetches the homepage, follows internal links to your most informative pages (about, services, contact, team), and runs the combined content through a multimodal model that pulls out three layers:
- Identity layer — what your business is, what it sells, who it serves, where it operates, and what tone the existing copy uses.
- Visual layer — the colours, fonts, and logo it can detect on the page so generated images match your existing brand.
- Strategy layer — the audiences your site speaks to and the content themes those audiences care about, used to suggest what to post about.
The whole thing typically completes in under a minute. You can edit every field after the fact — the analysis is a starting draft, not a fixed call.
What exactly does Rheos pull from my site?
The brand profile splits into four blocks you can review and adjust:
| Block | Examples of what's extracted |
|---|---|
| Business identity | Company name, what you do, what you sell, your mission, who your customers are |
| Brand kit | Primary colours, secondary colours, font family, logo (light + dark variants) |
| Audiences | 2–4 audience profiles with goals, pain points, and demographic notes |
| Content themes | 4–8 themes (e.g. "behind the scenes", "product education", "customer wins") used to seed post ideas |
Everything is editable. If your site is light on content (a one-pager, a coming-soon page) Rheos will produce a thinner profile and prompt you to fill in the gaps manually before it generates anything.
How long does the website analysis take?
For most small business websites the full analysis completes in 60–90 seconds. Larger sites with deep navigation can take up to two minutes. You don't have to sit and wait — the brand profile keeps building in the background while you start exploring the dashboard.
If your site is on a JavaScript-heavy framework that doesn't server-side render, Rheos uses a headless browser to wait for content to load before reading. The trade-off is a slightly slower analysis but the same end result.
What if Rheos gets my brand voice wrong?
You edit it. Every field — identity, audiences, themes, colours, voice descriptors — is editable from the brand settings page at any time. Two practical patterns most owners use:
- At setup: spend five minutes refining the voice descriptors and audience details before generating your first post. The first draft of everything else gets dramatically better.
- Over time: when a generated post lands wrong, mark the bit that doesn't sound like you and rewrite it. Rheos remembers those edits and biases future drafts away from the patterns you rejected.
You're not locked into the AI's first read. Treat it as a draft you tighten, the same way you would any analysis of your own brand.
What kinds of content can I generate once the profile is built?
Once the brand profile exists, the same one source feeds every content type:
- Text posts — captions for Instagram, posts for LinkedIn, short copy for X, Bluesky, Threads
- Images — branded graphics that use your colours, fonts, and logo
- Carousels — multi-slide posts for Instagram and LinkedIn
- Video scripts — short-form outlines with scenes and on-brand text overlays
- Articles and long-form documents — blog posts and longer pieces written in your voice
You don't re-set up your brand each time. The image, carousel, and text generators all read from the same brand profile, which is why the output stays coherent across formats.
How is this different from a generic AI tool like ChatGPT or Claude?
The difference is what the model sees before it writes. With ChatGPT you give it a prompt and it generates from its general training. With Rheos the model is given your prompt plus your full brand profile plus any prior posts you've approved as reference, and the output is constrained to fit the profile.
In practice this means:
- A "post about our new product launch" prompt in ChatGPT returns a generic launch announcement
- The same prompt in Rheos returns a launch post in your tone, with your audience in mind, in your visual style if it's an image, with a CTA shaped like the CTAs you already use
Generic tools save you keystrokes. Rheos saves you the work of making generic AI output sound like your business in the first place.

The 20-minute rule
Most owners we work with budget 20 minutes a session. With a generic AI tool that 20 minutes is mostly spent rewriting the AI's output to sound like you. With Rheos the 20 minutes is spent reviewing, tweaking, and scheduling — the heavy lift of "make this sound like me" is already done by the brand profile.
Frequently asked questions
Summary
Rheos turns your website into a working brand profile in under a minute, then uses that profile to draft every post — text, image, carousel — in your voice and visual style. You edit anything that isn't right, generate the next post, and ship it.
If you've been using generic AI tools and rewriting half the output to make it sound like your business, the website-read-then-generate pattern is the bit that closes that gap.
