Key Features
- Extensions for VS Code, JetBrains and web workspace
- Natural language to code, tests and SQL
- Doc search to surface usage examples and patterns
- Explainer mode to summarize code and errors
- Multi language support covering popular stacks
- Snippets library to reuse and share code
- Free and Pro plans: Pricing starts at $0 with 50 credits and Pro at $25 with 200 builder credits so solo builders can scale testing
- Prompt playground: Compare models side by side and iterate prompts systematically instead of relying on subjective testing
- Evaluations framework: Run repeatable quality tests at scale to detect regressions and track improvements across prompt versions
- Hosted agent apps: Share working agents with teammates through hosted apps for demos
- reviews
- and stakeholder feedback cycles
Use Cases
- Generate boilerplate and helper functions quickly
- Create unit tests from specs or examples
- Refactor legacy code into clearer idioms
- Draft SQL queries and validations from prompts
- Explain error messages to speed debugging
- Look up usage patterns without leaving the IDE
- Agent prototyping: Build an agent by chatting with AI then refine logic with low code steps and controlled prompt versions
- Prompt iteration: Compare LLM outputs side by side and select prompts that improve accuracy and reduce unwanted variation
- Regression testing: Run evaluations on a saved dataset before release to catch quality drops after model or prompt changes
- RAG apps: Attach a knowledge base and test retrieval behavior with representative questions and strict document scope rules
- Stakeholder demos: Publish hosted agent apps so product and compliance reviewers can test behavior without local setup steps
- Model selection: Evaluate providers and self hosted options with the same tasks to choose the best cost and latency mix for production
