Align API

Align API works as an API layer that sits between your users and your AI model, checking prompts before they are sent for inference.

Align API is a content guardrail tool that detects NSFW and other sensitive prompts for developers building AI applications.

Because flagged prompts never reach the model, you do not pay for inference on requests you would have rejected anyway.

The main promise is practical.

Blocking bad prompts early protects your brand and lowers the risk of being banned by platforms such as OpenAI, Apple or Google, which is a real concern if your app lets the public type anything they like.

Align API also detects sensitive topics, so you can decide what counts as off-limits for your product.

Beyond blocking, Align API offers prompt cleaning and lets you align prompts with your own values and brand.

That means a questionable request can be adjusted rather than simply refused.

It is described as plug-and-play, so you add it in front of your existing setup instead of rebuilding your app around it.

Teams shipping consumer-facing AI features are the obvious fit.
