Your AI can be hacked in seconds. AI Fuzzer finds prompt injection, jailbreaks, and data leaks before attackers do — and hands you an auditable report mapped to the OWASP LLM Top 10 and the EU AI Act.
How it works
Point AI Fuzzer at your system, run the payloads, read the transcript. Fix, re-scan, and show the finding is gone.
An API with a key, a request captured from your browser, or a local agent inside your network.
Every payload fires, each mutated 14 ways to slip past filters. Findings land live.
Each finding shows the exact prompt and response, scored and mapped to OWASP & the EU AI Act.
Export the report, fail your CI build on criticals, re-scan to verify the fix.
Built for how AI ships
Test any AI, however it's deployed — without exposing it to anyone.
Point it at an endpoint with a test key. Presets for OpenAI- and Anthropic-style APIs.
For chatbots behind a login or CSRF. Paste one request from your session; we replay it.
For internal-only systems. Scan localhost inside your network; only findings sync back.
Every finding shows the exact prompt and response. A refusal is a pass, not a finding.
Reports mapped to the OWASP LLM Top 10 and EU AI Act articles.
A CI/CD gate fails the build on critical findings. Drive it all via REST API.
Verify domain ownership before scanning any public target. A security product, not an attack tool.

No. If your AI is internal-only (localhost, a private network, a VPC, behind a VPN), you download a small agent and run it on a machine inside your own network that can reach the AI. It scans locally and sends only the findings back to your dashboard over HTTPS — your system and its traffic never leave your network. If your AI is behind a login, you capture one request from your own browser instead.
Anytime. You keep access until the end of the period you've paid for.
No free trial — but you can cancel after your first month if it's not for you.
Any HTTP AI endpoint. Presets for OpenAI- and Anthropic-style APIs, plus streaming (SSE) and CSRF/session apps like Laravel, Rails, Django.
You must verify domain ownership before scanning any public target. Localhost and private networks are exempt.
