Private Claude vs Hathr.AI

Both are built on Claude. Both are BAA-backed. Side-by-side on deployment, target buyer, audit, and what's right for whom.

Why these two get compared

If you've been searching for a HIPAA-friendly way to use Claude, you've probably landed on both products in the same browser tab. Here's what they have in common: both run on Anthropic's Claude under the hood. Both market a Business Associate Agreement. Both are aimed at regulated buyers who need more than what Claude.ai gives them out of the box.

That's where the similarities end. The deployment model is different. The pricing posture is different. The target buyer is different. And the answer to "which one should I pick" depends almost entirely on your team size, your procurement style, and how much control you want over where the chat layer actually runs.

This post walks through both honestly. We're the team behind Private Claude, so we'll be transparent about that. But we're not here to trash Hathr. They're a real product solving a real problem. The goal is to help you pick the one that actually fits your operation. For a wider view of the BAA-backed Claude landscape, see our HIPAA AI vendor comparison.

Hathr.AI: what it is

Based on publicly available information at time of writing, Hathr.AI is a BAA-backed Claude wrapper delivered as a hosted web application. They market to clinical and healthcare buyers, and to regulated SMBs that want a chat experience without building anything themselves.

The pitch is straightforward: log in, get Claude, BAA available. You don't manage an Anthropic key. You don't manage infrastructure. You pay Hathr, they handle the rest. That's the typical SaaS shape, and for a lot of clinics, it's exactly the shape they want.

We're going to be careful here. Specific Hathr feature claims, pricing details, and architectural specifics beyond "BAA-backed Claude SaaS" should be verified directly with Hathr at the time you're evaluating. AI products move fast, and we'd rather hedge than fabricate.

Private Claude Business: what it is

Private Claude is a BAA-backed Claude product with a different design philosophy. Instead of running a hosted multi-tenant SaaS, we let you bring your own Anthropic API key (BYOK) and offer VPC deployment for buyers who want full control of where the application runs.

The product comes in tiers, all with public pricing:

• Free. 50 Haiku messages and 25 Sonnet messages, BYOK. For trying the product.
• Basic, $17/mo. Unlimited messages, BYOK, file uploads, Markdown export.
• Pro, $37/mo. Everything in Basic plus saved system prompts, prompt library, faster send speed. The right tier for most solo regulated professionals.
• Business White Label, $1,449/year. BAA available, admin controls, audit logs, custom domain, branded experience for your team or clients.

The Business tier is where the comparison to Hathr actually lives. Everything below it is for solo professionals. We have a deeper writeup of the regulated-buyer architecture in our BAA-backed AI chat overview.

Architecture difference

This is where the two products diverge most clearly.

Hathr.AI runs as a hosted multi-tenant SaaS. Your team logs into their app. Their stack handles auth, the Anthropic call, and (presumably) chat history storage on their infrastructure. You trust Hathr's environment, their auditors, and their security posture. This is the model most healthcare SaaS works under, and it's totally legitimate.

Private Claude runs on a different model. Two key pieces:

• BYOK with zero application storage. You connect with your own Anthropic API key. The conversation lives in your browser tab, not on our servers. We don't have a database of your chats because we don't store them. The privacy guarantee is structural, not policy-based.
• VPC deployment available. For buyers who want maximum control, we can deploy the Private Claude application into your own cloud account (AWS or GCP). The chat layer runs on infrastructure you own. Anthropic still runs the model, but the wrapper around it is yours.

If you want a one-line summary: Hathr asks you to trust their stack. Private Claude lets you bring your own key and, optionally, run on your own stack. Different shapes, different buyers.

Pricing transparency

Private Claude pricing is public. You can see every tier on the site, sign up online, and start using the free tier without talking to anyone. The Business White Label is $1,449/year flat. No "contact sales for a quote" gate.

Hathr.AI's pricing model, based on publicly available information at time of writing, appears to be contact-based. That's not unusual for healthcare SaaS, and it doesn't make them worse. But if your procurement style favors public pricing (a lot of solo practitioners and small clinics do), that's worth knowing up front.

Here's the honest read: contact-based pricing usually means the vendor wants to qualify the lead, scope your usage, and price accordingly. That's fine if you're a 50-seat clinic. If you're a 2-person practice, it can feel like overkill. Public pricing is friction-free for small buyers, period.

Who should pick what

This isn't a "we're the answer to everything" post. The honest call:

Pick Hathr.AI if: you want a turnkey hosted SaaS for a clinic or small healthcare practice, you don't want to manage an API key, and you prefer SaaS simplicity over architectural control. If "log in and go" is your priority and you're comfortable with the SaaS trust model, they're a reasonable choice.

Pick Private Claude if:

• You're a solo practitioner where $37/mo Pro is a much better fit than enterprise SaaS pricing.
• You value BYOK transparency. Your Anthropic key is yours, your usage costs are visible, and you can leave any time without losing access to Claude.
• You want VPC deployment optionality. Maybe not on day one, but the option to move to your own cloud later matters.
• You want public pricing and self-serve signup, not a sales call to find out what it costs.
• You're building a white-label experience for your own clients (a small clinic offering AI to its patients, or a consultant offering branded Claude to their network).

Honest tradeoffs of both

Every product has costs. Here are the real ones for each.

Hathr's tradeoffs. It's hosted SaaS, so you trust their stack. That's not a flaw, it's just the model. You don't get BYOK, so you can't take your Anthropic relationship with you if you leave. Pricing opacity at time of writing means smaller buyers may bounce off the contact-sales gate before ever seeing the product.

Private Claude's tradeoffs. BYOK is one extra setup step. You have to grab an Anthropic key and paste it in. For some buyers, that's a feature (transparency, no lock-in). For others, it's friction. We also don't store chat history by default, which is a privacy feature but a real limitation if your team wants a shared, searchable archive of past chats. We offer audit logs (who logged in, when, what model) on the Business tier, but no user-facing shared chat history. If your team workflow depends on going back to last month's chat, Private Claude isn't the right shape without us building you something custom.

The other thing worth saying: we're a smaller team than Hathr. If you want a vendor with a 50-person customer success org, we're not it yet. If you want a vendor that ships fast, listens to your feedback, and has the founder on the email thread, that's us today.
