Your AI. Your data. Your call.
Backplain puts 47 models in one governed workspace. One prompt, up to ten simultaneous answers, sensitive data identified and stripped before your prompt reaches any model.
You don't have to trust one model. You can test all of them.
The Tokyo Test is not a product demo. It is a demonstration that you have a problem you did not know you had.
Ask ten models what the population of Tokyo is. Some say 14 million — Tokyo proper. Some say 37 or 38 million — the greater metropolitan area. Both are defensible. Neither is wrong. And if you had asked only one, you would not know how much the answer depended on which model you chose.
Now apply that to an indemnification clause. A clinical trial protocol. A regulatory filing. The variance is the same; the stakes are not.
Backplain sends one prompt to up to ten models simultaneously. The answers appear side by side. You pick the one that holds up. The others were the research.
The model never sees what it shouldn't.
A patent-pending sensitive-data obfuscation system, built into every Backplain tier. Three modes per filter category. PII, PHI, financial credentials, and any custom term your admin defines.

One of our customers switched to Claude Enterprise. They kept five Backplain seats anyway.
Backplain does not ask you to replace what you already use. That is not how this works.
One customer migrated their organization to Claude Enterprise — a reasonable choice for a company that has settled on a primary AI workflow. They kept five Backplain seats for model comparison, independent research, and any prompt they wanted a second opinion on from a non-Anthropic model.
They also kept them because Claude Enterprise does not have an AI Firewall.
If Copilot is your daily driver, Backplain is your research instrument and your compliance record.
If you are already on ChatGPT Business, Backplain adds 46 other models, the AI Firewall, and the audit log you do not have yet.
You do not have to pick. That is the point.
Flat rate. No tokens. No surprises.
Every model in your plan. All month. One number on your invoice.
No token costs. No usage alerts from your CFO. No per-call billing that turns a productive month into an unexpected line item. What you pay in January is what you pay in December.

Sarah Chen has three people on her legal team.
One of them is using ChatGPT on a personal account tonight.
She knows this. She does not know which client's documents were shared, what the model's data-use policy is, or whether it logged the session. She does not know because there is no way to know. Not without Backplain.
Three seats. Full governance. AI Firewall on. Every session logged. Same workspace for all three — Sarah, the contract attorney, and the paralegal. Deployed in a day. No IT project required.
When the CEO asks whether the company is using AI safely, Sarah pulls up the admin console and answers in four minutes.
47 models. 9 providers. One workspace.
Toggle any of them on or off. Bundle favorites into named groups. Let different departments see different sets. Up to 10 in any single comparison.
Point your phone at a contract.
Ask ten models about it.
Camera multi-chat and voice multi-chat. In a client meeting. In deposition prep. Anywhere a document is in front of you and you do not have time to wait.
"Backplain replaced four ChatGPT subscriptions and answered the governance question I'd been avoiding for nine months. It's now the primary AI tool the legal team uses."
We're not Harvey. That's the point.
Different buyer, different price, different problem. The comparison is not about which tool is better — it is about which tool was built for you.
