We help engineering teams find and eliminate hidden waste in their AI API spend.
AI is transforming how teams build software — but the costs add up fast. Most teams have no idea that 20–40% of their AI API spend goes to duplicate prompts, oversized models for simple tasks, and redundant calls that could be cached.
TokenLens was built to make that waste visible. Upload your logs, and in seconds you'll see exactly where your money is going — and how to get it back.
TokenLens is designed, developed, and maintained by PrAry Soft — a software company focused on building developer tools that solve real problems with clean, practical solutions.
We believe in shipping useful software: no bloat, no vanity features, no dark patterns. Every feature in TokenLens exists because it saves engineering teams real money.
We never store your API keys. Log data is processed in memory and encrypted at rest. Free tier data is auto-deleted after 7 days.
TokenLens never touches your production systems. We analyze log files you provide — we never make API calls on your behalf.
No setup wizards, no week-long onboarding. Upload a log file and see your waste breakdown in under 10 seconds.
Not just charts — specific recommendations for caching, model downgrades, and prompt optimization with projected savings.
TokenLens uses a 5-layer detection engine to identify waste patterns across your AI API logs:
Layer 1: SHA-256 exact deduplication (100% precision) · Layer 2: MinHash LSH near-duplicate clustering · Layer 3: N-gram overlap for paraphrase detection · Layer 4: Template matching for structured prompts · Layer 5: Semantic clustering for conceptually similar calls.
The adaptive learning engine continuously improves detection accuracy based on your feedback, adjusting thresholds and pattern sensitivity over time.
