MutableAI
Coding assistant that generates edits explains and refactors code with a browser IDE extensions and Codebase features for large scale changes.
MutableAI has been discontinued. The product was shut down, absorbed into another company, or now operates under a different brand. The information below is kept for reference and may describe the tool as it was.
Overview
MutableAI accelerates software work by generating code from natural prompts, applying refactors and documenting changes in context. Developers start in the browser IDE or connect VS Code or JetBrains, then ask for functions, tests or architecture adjustments. Codebase mode proposes multi file changes and smart PR summaries so reviews move faster.
Public pricing pages and trackers show a free tier and paid seats that start near $10 per month for individuals with higher Pro tiers around $25 per month and enterprise by quote. Teams adopt MutableAI to speed prototyping and standardize routine edits, while keeping humans in control through diffs and PRs. Integrations and model options continue to expand, which makes it a practical fit for shops comparing copilots on cost and accuracy.
