Hi PH! 👋 I built TokenLens because every "token counter" I found was either inaccurate, plastered with ads, or vague about which tokenizer it actually used.
Three things I focused on:
🔍 Accuracy — OpenAI models are counted with the real o200k/cl100k tokenizers; other vendors are clearly marked as estimates
📊 Context + cost in one view — see where your text lands in each model's context window and what it costs, with pricing auto-synced from the open-source LiteLLM database
🔒 Privacy — everything runs in your browser; the only external request is the pricing data
It's a single HTML file, fully open source: https://github.com/Tliens/TokenLens
Would love your feedback on which models to add next!
