AI-assisted URL threat detection API for developers
Every scan returns a numeric score plus explanatory reasons, so you can act on a link with confidence rather than trusting an opaque verdict.
Short links and redirect chains are unwrapped and followed, revealing hidden final destinations before they reach your users.
Links are classified across phishing, malware, scam, adult, dating, gambling, crypto and spam, supporting nuanced content policies.
Send batches of URLs in a single request and receive per-link risk scores, which suits high-volume pipelines and link shorteners.

Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.

Detect AI-generated text and images with benchmark-tested accuracy
SpecialistFocuses heavily on privacy-first document chat and local RAG pipelines, but offers fewer general-purpose chat UI features.
AI detector that highlights evidence, not just a score

Multi-modal AI detection API that flags synthetic images, text, audio, video and deepfakes

Free / Open-sourceOffers robust multi-provider support and advanced user permission management, but has a slightly different configuration setup.
Free / Open-sourceDelivers a desktop-native application for running local models offline easily, but lacks Open WebUI's server-centric multi-user features.
