Prompt engineering,
done right
Version tracking, live token budgets, variable inspection, few-shot curation, and an AI-powered optimizer — everything you need to write better prompts, faster.
Version Tracking
Every edit is a version
The Prompt Engineering Studio automatically saves a version snapshot every time you update a prompt. Browse your full history, compare any two versions side by side, and restore a previous version with one click.
- Automatic version snapshots on every save
- Side-by-side diff comparison between any two versions
- One-click restore to any previous version
- Author and timestamp metadata on every version
Token Budget
See exactly what your prompt costs
A live token counter shows the token count for your prompt, input variables, and few-shot examples — broken down by model. Stay within context limits and optimize for cost before you run.
- Live token count updated as you type
- Per-model breakdown (different tokenizers, different counts)
- Visual budget bar showing usage against model context limit
- Separate counts for system prompt, user input, and few-shot examples
Variable Inspector
Know every placeholder in your prompt
The variable inspector scans your prompt for all {{placeholder}} variables and displays them in a panel. Fill in test values, see which variables are unused, and catch typos before they cause runtime errors.
- Automatic detection of all {{placeholder}} variables
- Test value input for each variable
- Warnings for undefined or unused variables
- Quick-insert to add new variables from the inspector
Few-Shot Curation
Curate examples that teach the model
Add, reorder, and manage few-shot examples directly in the studio. Drag and drop to prioritize the most effective examples, and see how each example affects token usage and output quality.
- Add input/output example pairs with a form
- Drag-and-drop reordering to prioritize examples
- Per-example token count to manage budget
- Enable/disable individual examples without deleting them
Optimizer
Let AI improve your prompts
The AI-powered optimizer analyzes your prompt and suggests concrete improvements. It identifies vague instructions, missing constraints, and opportunities to reduce token usage — then generates an improved version you can accept or modify.
- One-click prompt analysis and improvement suggestions
- Identifies vague instructions and missing constraints
- Suggests token-efficient rewrites without losing meaning
- Accept, modify, or reject each suggestion individually
Better Together
Part of a complete prompt lifecycle
The Prompt Engineering Studio integrates with Quality Guard and Bakeoffs to give you a full write-test-monitor loop.
Write
Craft and optimize prompts in the studio with version tracking and AI suggestions.
Test
Compare prompt versions with Bakeoffs to find the best performer.
Monitor
Attach a Quality Guard to track output quality in production and catch regressions.
