Brief once.

No account required. Free forever. ~$3–50/mo in Anthropic API costs.

What Blair actually produces

Real outputs, in your voice, from the first message.

Cold email/blair:cold-outbound VP of Sales at Series B SaaS

"Hey [First] — saw you're scaling the AE team at [Company]. Most VPs I talk to are still having their reps Google ChatGPT prompts with no real system. We built a structured framework for exactly that. Worth 15 min?"

Campaign brief/blair:campaigns Q3 acquisition push

"Q3 Acquisition Campaign

Goal: 500 email subscribers by Sept 30
Primary channel: LinkedIn organic + cold outbound
Core message: Your reps are already using AI — give them the system that actually works..."

LinkedIn post/blair:linkedin thought leadership post

"Most sales AI tools are built for marketers.

Your reps don't need another content calendar. They need prompts for discovery calls, objection scripts, and follow-ups that don't sound like ChatGPT.

Here's what we built instead:"

Frequently asked questions

Do I need an Anthropic API key?

Yes. You bring your own key — Blair never stores or touches it. You pay Anthropic directly and control your own usage. Typical cost is $3–50/month.

Is my brand data safe?

Your brand profile lives in your own database instance, not a shared cloud. You own and control your data. If you're self-hosting, it never leaves your infrastructure.

Why not just paste a brand doc into ChatGPT?

You can — and most founders do. Blair automates exactly that. Answer 7 questions once and your brand context is injected into every future session automatically. No pasting, no forgetting, no drift.

Does this work for agencies managing multiple brands?

Blair is designed for single-brand use today. Multi-brand support with isolated profiles per client is on the Blair Pro roadmap. Join the waitlist to get early access.

What AI model does Blair use?

Claude by Anthropic by default. You configure the model (Sonnet, Opus, Haiku) in your API settings based on your cost and quality preferences.

Can I self-host or contribute?

Yes on both. Blair is MIT-licensed. Fork it, self-host it, or submit a PR on GitHub.
