Join Pro Waitlist
Analysis runs locally. Signed-in history stores token counts only.
Preflight safety system for AI products in production.
Detect token overflow, cost drift, and production risk before you ship.
Used by AI founders before every deploy.
Why This Matters
Token Overflow
Truncation → broken outputs → silent failure in production.
Cost Drift
Margins collapse at scale when token usage expands unnoticed.
Risk Score
Signal of production instability — not legal advice, just operational risk.
Drift Tracking
Monitor token and cost drift across model versions over time.
Batch Analysis
Run preflight checks on multiple prompts simultaneously.
Model Comparison
Compare cost and risk across models before committing to one.

Who This Is For
AI SaaS Founders
Shipping prompts into production and need cost + failure visibility before scaling.
Product & ML Teams
Monitoring token usage and drift across models and deployments.
AI Infrastructure Engineers
Preventing overflow, runaway costs, and silent degradation.
How Preflight Works
1
Analyze
Estimate tokens, cost, compression, and risk before deployment.
2
Simulate
Adjust output length and compare models to understand scale impact.
3
Deploy Safely
Ship with predictable cost and reduced production risk.
