Estimate rough token usage for prompts, code-heavy text and documents without calling an AI API. Pocket Dev helps you understand size, word count and context usage locally.
What it does
Estimate prompt size before sending it to an AI tool.

Context window percentage
See how much of an 8k, 32k, 128k or 1M context window your text may use.
No API request
The text stays in your browser and is not sent to an AI provider.
How to use
Use Token Estimator in a few steps.
- Open the Token Estimator tool inside Pocket Dev.
- Paste a prompt, document or code snippet.
