Limina, formerly Private AI, suits data teams that need to clean large volumes of regulated data. Hushbridge suits people who want to use AI on client work and get the real details back.
Developer API
Private AI rebranded as Limina on 5 March 2026. A Government of Canada notice from May 2026 lists the company as “Private AI (o/a Limina)”, based in Toronto. Limina is an API that finds and replaces sensitive data before it is used. It serves pharma, healthcare, financial services, contact centers and insurance. You can run it inside your own network.
Local protection layer
Hushbridge works on the prompt in front of you. On your device it swaps details for placeholders such as [PERSON_1] and shows you what the AI will get. After you review it, the placeholder version goes to the AI. Real values come back on your device. It fits professionals using AI sites and developers adding one step to an AI call.
| Question | Limina (Private AI) | Hushbridge |
|---|---|---|
| What it protects | Personal, health and payment data in text, images, audio and documents. 50+ entity types in 52 languages. | Names, identifiers, addresses, secrets and anything on your own "always protect" list, in text you type or paste. Latin-script text only. |
| Where processing happens | Your choice: a container in your own VPC or data center, a cloud marketplace (AWS, Snowflake, Azure), or Limina’s hosted service. | On your device. |
| Where original values are stored | Not published for a restore workflow. With the container, Limina says data stays in your infrastructure. | In a swap table that stays on your device. |
| Restore in replies | Not documented. Limina lists redaction, pseudonymization, synthetic replacement and generalization. | Yes. Real values return on your device in supported replies. |
| How you use it | Your developers call the API from your code or batch jobs. | A browser extension for ChatGPT, Claude, Gemini, Copilot and Perplexity, a web workspace, or the SDK and local proxy in your own code. |
| Deployment | Self-hosted container, marketplace, or Limina’s cloud. Enterprise adds hybrid, regional and multi-region options. | The extension installs manually in Chrome with "Load unpacked". It is not in the Chrome Web Store yet. Workspace and billing run on tightlipai.com during the move to the new name. |
| Pricing | Starter is free: 75 API calls a day, 10 a minute. Batch is volume pricing by quote. Enterprise is custom. No other USD figures are published. | USD 0.05 per credit. Top-ups from USD 100.
