What is Recast?

Recast takes messy output from AI models and returns clean, valid JSON, along with a plain-language list of each change it made. The page shows example problems it handles: single quotes, Python-style True values, trailing commas, prose and code fences wrapped around the data, truncated output that gets an honest repair, and exports from tools like n8n where the useful payload sits inside another structure. An option, off by default, unwraps fenced JSON that is found inside strings. You paste the input, optionally start from a built-in example, and read the status and fix list that come back. The page says everything runs in your browser and that your data never leaves it. It targets developers who parse model responses in pipelines. No pricing or plans appear on the page, so check the site for any limits.

Use cases

Why use Recast

  • The fix list shows exactly how your output was changed, so you can trust or reject the result.
  • In-browser processing keeps model output on your own machine.
  • It handles several common failure modes in one pass, so you do not need separate regex clean-ups.
  • Built-in examples let you see the behavior before pasting your own data.
