Key Features
- Unlimited code completion: Mellum powered suggestions inside the IDE for fast autocomplete that adapts to your project context
- Cloud completion mode: Autocomplete lines blocks and whole functions using AI Assistant when cloud credits are available
- Context-aware AI chat: Ask questions about code and get answers that reflect open files and the current project structure
- Commit message help: Generate or refine commit messages using IDE context so summaries stay aligned with the actual diff
- Test generation support: Produce starter unit tests and edge cases from selected code to speed coverage and reduce regressions
- Local AI support: AI Free includes local model support so some assistance can run without sending code to cloud services
- Context builder that ingests logs tests and code to frame problems for the assistant
- Runnable sandboxes to execute failing cases and verify fixes
- Patch proposals with side-by-side diffs and explanations
- Search and trace tools to find root causes quickly
- One-click exports of patches and notes to repos or tickets
- Lightweight UI that keeps focus on reproduction and fixes
Use Cases
- Inline coding flow: Accept completions for repetitive patterns so you can focus on domain logic and architecture decisions
- Refactor support: Ask the chat to explain a class or function then implement changes with IDE refactor tools and verify quickly
- Test coverage boost: Generate starter tests for critical paths then adjust assertions to match your business rules and data shapes
- Commit hygiene: Draft concise commit messages that reflect the actual diff and reduce review friction in pull requests during merges
- Learning a codebase: Use chat with open file context to understand unfamiliar modules and navigation paths faster during onboarding
- Bug fixing: Request a minimal change suggestion then step through in debugger to confirm behavior matches the intent in production
- Reproduce hard-to-pin bugs from logs and failing tests
- Generate minimal patches with explanations for reviewers
- Isolate flaky tests and propose deterministic rewrites
- Onboard to unfamiliar services by tracing key flows
- Document fixes with clean diffs and notes for QA
- Compare alternative patches and benchmarks quickly
