Safety and Trust, Built In
Chat4U protects your business and your visitors at every layer — from model output to data storage.
Configurable AI Safety Controls
Multiple layers of protection keep your agent on-topic, accurate, and safe.
Prompt Protection
Blocks manipulation attempts and off-topic questions before they reach the AI. You decide which topics your agent can and can't discuss.
- Manipulation & abuse blocking
- Topic allow/block lists
- Sensitive information protection
Answer Verification
Every response is checked against your actual content before it's shown to the visitor. Answers that can't be verified are caught and corrected.
- Factual accuracy checks
- Sensitive content filtering
- Automatic response correction
Content Quality Filtering
Only the most relevant parts of your content are used to form answers. Low-quality or off-topic material is filtered out before the AI sees it.
- Relevance scoring
- Per-agent quality threshold
- Automatic noise removal
Automatic Failsafe
If any safety system encounters an issue, a failsafe engages automatically. You choose whether to allow or block responses during temporary disruptions.
- Self-healing safety systems
- Configurable fail behavior
- Allow or block on disruption
Infrastructure Security
Data Isolation
Every project has its own isolated database. Your content is never mixed with other customers' data.
Encryption Everywhere
All data is encrypted at rest and in transit. API keys are encrypted and stored securely.
Domain Restrictions
Your widget only responds to requests from your configured domains — preventing unauthorized use of your agent.
No Training on Your Data
Your content, conversations, and user data are never used to train AI models — by us or our AI providers.
Sensitive Field Protection
Pro Agents automatically avoid password fields, payment inputs, and other sensitive areas — they're blocked by design.
Compliance & Documentation
We take our obligations to your users seriously.
