Your AI feature will break quietly one day —
and you'll be the last to know.
Models get deprecated, output formats drift, answers start refusing, latency explodes. Traditional monitoring only tells you the site is still alive — not that its answers got worse. ChirpPal wraps each real AI call with one line and alerts you the moment it breaks.
One-line wrapper · 5-minute setup · fail-open, never touches your production path.
AI features break differently from normal websites
- The model you rely on gets deprecated, and the replacement returns a completely different format.
- You tuned a prompt for three months — then the model silently changes version and the answers "mean" something else.
- It starts prefixing replies with "As an AI…", or randomly begins to refuse.
- Responses get twice as slow, start mentioning competitors, or return invalid JSON that blows up your downstream parser.
None of this triggers a single 5xx. Your dashboard stays all-green. Usually a customer notices first — and then you're scrambling.
Three steps, five minutes.
Wrap one line around your AI call
(or paste our integration prompt into your AI tool and it auto-adds it). The wrapper watches every real call locally, fail-open.
Pick what "broken" means
Start with simple rules — valid JSON, no competitor names, latency, no refusals. Add semantic drift and off-topic detection as you grow.
Get told when it breaks
Email, Slack, Discord — with the offending response and which check failed, so you (or your AI tools) can fix it right away.

Free: Model Deprecation Radar 🛰️
Tell us which models you use (OpenAI / Anthropic / Gemini). We email you before they get deprecated. No signup required. (Price & behavior-change alerts coming soon.)

FAQ
Do I need to change my code?
Just one line — wrap your AI call, or paste our integration prompt into your AI tool (Cursor / Copilot / Claude Code) to auto-add it.
Will it affect my production?
No. The wrapper is fail-open side-channel telemetry — not a proxy, it doesn't block your request. If we go down, your AI keeps running; you just miss that window of telemetry.
How is this different from Langfuse / Helicone?
Those are heavy instrumentation for engineering teams. ChirpPal is a smoke alarm for indie devs who shipped one or two AI features and just want to know when they break.
Do the checks use my OpenAI / Anthropic budget?
No. Deterministic checks run locally in the wrapper, and drift and semantic checks run on our backend with our own models — never your keys or token budget. (Free is deterministic-only; drift and semantic checks start on Pro. Hover the "?" in the pricing table for what each check does.)
