Everything you need
Personalisation without the complexity
Blether handles the hard parts — you just decide what to personalise.
One line to install
Add <script src="setup.js"></script> and you're live. No framework, no build step, no developer needed to get started.
Click to configure
Open your live site and click any element you want to personalise. Blether maps it automatically — no HTML knowledge required.
Personalise everything at once
Headlines, subheadings, body copy, CTAs — all generated in a single AI request. Coherent, on-brand, and ready instantly.
GDPR-ready analytics
Session tracking, geo-location, UTM attribution, and CRM tokens built in. EU visitors get automatic consent flows.
Every language, every tone
Reach visitors in their language. Set the tone — Professional, Smart, Funny, or fully custom — and it stays consistent across every element.
Built for developers too
Dev mode, custom CSS injection, domain allowlisting, and configuration tokens. Full control when you need it.
How it works
Up and running in minutes
Three steps from zero to a personalised website.
Add the bar to your site
Drop one script tag into your site. Blether appears immediately — no build step, no configuration file, no developer required.
<script src="setup.js"></script>Visitors introduce themselves
A clean input bar appears on your page. Visitors type what they do, what they're looking for, or what problem they're trying to solve.
“I'm a wedding photographer in Edinburgh looking for a CRM.”
Your content transforms
Blether rewrites the elements you've chosen — headlines, body text, calls-to-action — tailored to that visitor. Instantly, every time.
“Headlines, body copy, and CTAs — personalised in one request.”
Analytics
Know every visitor. Respect every privacy.
Blether tracks what matters — without asking for things visitors won't give. IP-based geo-detection, session identity, UTM attribution, and CRM tokens all run server-side. EU visitors get a GDPR consent prompt automatically, no configuration needed.
- Persistent session tracking across visits
- Server-side geo-location — no browser permissions
- Automatic GDPR consent flow for EU visitors
- UTM & referrer attribution
- HubSpot and Salesforce token support

Developer tools
Full control, when you need it.
Marketing teams can get up and running without touching the codebase. But when developers want control, Blether hands it over completely. Dev mode, custom CSS, domain restrictions, and configuration tokens give you a rock-solid integration.
- Dev mode for unstyled, inspectable output
- Custom CSS injection per embed
- Domain allowlisting for security
- One-time & time-limited configuration tokens
- Full theme customisation

Language & tone
Every visitor, in their language.
Set the tone once — Professional, Smart, Funny, or write your own — and Blether applies it consistently across every element, every visitor, every language. Regional awareness means the copy feels local, not just translated.
- Multi-language output with regional variants
- Tone presets: Professional, Smart, Funny
- Custom tone instructions
- Page-type awareness (Home, About, Pricing…)
- Per-element custom AI instructions

What people say
The results speak for themselves
Blether cut our homepage bounce rate by 40% in the first two weeks. Every lead segment now sees a site that speaks directly to them.
Jordan K.
Growth Lead, SaaS platform
The installation literally took 90 seconds. We had personalised content running before our morning standup was over.
Sam R.
Founder, Digital agency
Our clients were sceptical about AI content. Blether's quality is good enough that none of them have noticed it's not hand-written.
