Returns a transcript of a short audio clip in a synchronous API response.

Hive

Application

Hive AI DetectorApplication

A free Chrome extension that scans an image, video, text or audio file on any web page for the likelihood it is AI-generated and, for images and video, names the generator it predicts was used.

Hive DetectApplication

Free web tool where a person uploads a file or submits a media URL and Hive's detection models report whether an image, video or audio clip is AI-generated or a deepfake, with a detailed analysis.

API service

AI-Generated & Deepfake Content DetectionAPI service

APIs that classify images, video, audio and text as authentic or AI-generated, flag deepfakes and predict which generative model likely produced the content, billed per use.

Hive Image Generation APIsAPI service

Hosted text-to-image API serving SDXL, Flux Schnell and Hive-enhanced variants of them, running every generated image through Hive's visual moderation model before it is returned.
