What This Update Actually Is
HubSpot shipped an improved version of Brand Voice that learns from content you actually wrote. Upload two or three examples, and the system analyzes your sentence structure, pronoun preferences, tone shifts, punctuation habits, and even your sense of humor.
The old Brand Voice let you describe your tone in words. This version reads your words and figures it out. That's a meaningful difference.
The update affects two specific surfaces right now: AI-generated blog posts (the "Start with AI" flow) and the Refine action inside Breeze Assistant. HubSpot has confirmed it will expand to more tools soon.
Why HubSpot Shipped This
The core problem is one we've seen in portal after portal: AI content sounds like AI content. It's grammatically fine. It hits the right topics. But it doesn't sound like the human who built the brand, which means every draft needs significant editing before it's usable.
That editing time erases the time savings that made AI appealing in the first place. Content managers get frustrated. Business owners get skeptical. The AI tools sit underused.
HubSpot heard this directly from customers. They ran tests across industries and the response was clear. One beta participant said it plainly: "This is heads and shoulders above the previous version." Another noted it matched how they like to tell a story. The internal frustration was real, and this update is a direct answer to it.
How to Use It Step by Step
Setup is straightforward. Follow these steps in order and don't skip step two.
- Go to Content Hub, then Brand, then click the new Content Samples tab.
- Upload two or three writing samples. Use content that represents your best, most authentic writing: a flagship blog post, a high-performing email, or a key website page. This step drives the entire result, so choose carefully.
- Assign each sample to a content type (blog, email, web content, etc.) so the system knows how to weight different stylistic signals.
- Wait two to three minutes for HubSpot to process the samples. You don't need to do anything during this window.
- Open Blog and use Start with AI, or open Breeze Assistant and use the Refine action. Generate content and compare the output to what you'd have gotten before.
- Submit feedback when HubSpot follows up. This is a public beta, and your input directly shapes how the feature develops.
One practical note: pick samples that represent the voice you want to project going forward, not just the voice you've used historically. If you've been working to shift your tone, use newer samples that reflect where you're headed.
What It Touches in Your HubSpot Strategy
Brand Voice lives inside Content Hub, but its ripple effects go wider than that. Here's where this change actually shows up in practice.
- Reduces post-generation editing time so your content team can ship more without burning out.
- Improves brand consistency across AI-assisted blog output, which matters for SEO trust signals and reader experience over time.
- Strengthens the Breeze Assistant Refine action so the AI rewrites feel like you wrote them, not like a generic editor cleaned them up.
- Sets a foundation for upcoming expansions to more Breeze surfaces, meaning the samples you upload today will carry forward as HubSpot rolls this out further.
If you've been following HubSpot's broader Breeze buildout, this update fits a clear pattern. Breeze is moving from "AI that assists" toward "AI that represents you." Understanding how Breeze operates across the full platform helps you place this update in context. Our deep-dive on what HubSpot's Breeze Assistant can really do covers the bigger picture.
Key Takeaway
The samples you upload are the most important variable in this whole feature. Two thoughtfully chosen pieces of your real content will outperform ten mediocre ones every time.
There's also a content strategy angle here worth naming. If you've been building a story bank or defining your content voice at the prompt level, this update makes that work compound. The humans on your team who've spent time articulating how you write now have a direct mechanism to encode that into HubSpot itself. Our recap on the prompt framework that actually works pairs well with this feature if you want to go deeper on AI content quality.
Key Takeaway
Brand Voice now works as a persistent style layer across Content Hub. Every time the AI generates or refines content, it's working from your real writing, not a generic persona description.
Who Should Care Most
This update matters most to a specific set of roles and company profiles. Here's how to know if it's worth your attention right now.
- Content managers and marketing leads at companies producing five or more blog posts per month. The editing time reduction is real and cumulative.
- Founders and owner-operators who have a very specific voice and have avoided AI content because it never sounds like them. This is the update that changes that equation.
- Small but mighty marketing teams where one or two humans produce most of the content and AI assistance is the only way to scale without hiring.
- Any Content Hub Professional or Enterprise account already using Blog AI or Breeze Assistant. You have access right now and the setup cost is under ten minutes.
If your team hasn't touched Brand Voice before because the previous version felt too shallow, this is worth revisiting. The mechanism is fundamentally different now.
George's Take
I've been in enough portals to know that Brand Voice has been the feature with the most potential and the most disappointment. Humans would set it up, run one AI blog, read something that sounded like a press release, and then never open it again. This update changes the core promise: instead of describing your voice, you're demonstrating it. That's a fundamentally better input. The two or three samples you upload are doing real work here, not just labeling a persona. My strong advice is to treat the sample selection seriously. Pull your three most-read, most-shared, most-you pieces of content. That curation matters as much as the feature itself.
“Stop describing your voice to AI and start showing it. Two great samples will do more for your content quality than any prompt you've ever written.”

Frequently Asked Questions
What is the new HubSpot Brand Voice content samples feature?
HubSpot Brand Voice now lets you upload two or three pieces of your real content, like a blog post or email, and the system learns your sentence structure, tone, pronoun use, and punctuation habits. AI-generated blogs and Breeze Assistant output then match your actual writing style instead of a generic default.
Which HubSpot tools does the improved Brand Voice affect?
As of the June 2026 beta, the improved Brand Voice affects two surfaces: Blog's Start with AI flow and the Refine action inside Breeze Assistant. HubSpot has confirmed it will expand to more tools, so the content samples you set up now will apply more broadly over time.
How do I set up Brand Voice content samples in HubSpot?
Go to Content Hub, then Brand, then click the new Content Samples tab. Upload two to three writing samples, assign each to a content type, and wait two to three minutes for processing. Then use Blog AI or Breeze Assistant's Refine action and compare the output to your previous results.
Who has access to the improved Brand Voice feature?
Any account on a Professional or Enterprise tier across Commerce Hub, Content Hub, Marketing Hub, Data Hub, Sales Hub, Service Hub, or Smart CRM gets access. The June 2026 launch is a public beta, so everyone in eligible accounts is automatically included with no opt-in required.
What kind of content should I upload as Brand Voice samples?
Choose two to three pieces that represent your best, most authentic writing. A high-performing blog post, a strong email, or a flagship web page all work well. Prioritize content that reflects where your brand voice is headed, not just what you've published historically.
Will the improved Brand Voice fix generic-sounding AI content?
For Blog and Breeze Refine, yes. Beta testers reported dramatically better results, with one saying the output was "heads and shoulders above the previous version." The key variable is sample quality. Uploading carefully chosen, representative content produces noticeably more on-brand output with less editing required.
