Context Estimator
Estimate token usage for long prompts so you stay within model context limits.
How to get the most from the library
Filter by category and platform, then copy the closest template to your task. Replace every placeholder in one pass before generating—partial placeholders cause models to guess.
Save favorites in your team wiki with version dates. When a model update changes output quality, revisit the template constraints first before abandoning the workflow.
