AST-aware patching from your clipboard or terminal. Route LLM edits to the right files, preserve omitted code, inspect every change, and roll back in one keystroke.
Works with code from ChatGPT, Claude, Gemini, Aider, local models, Git diffs and other sources.
LLM shortened a function with “... existing code ...”? Find stable anchors, preserve untouched logic, and stitch the missing sections against your real source.
The v3.59 HintScourer inspects prose, headers and comments while filtering hallucinated paths. File routing checks language and structure, not just a filename guess.
Use F9 to monitor copied replies, or run stitch attach, stitch patch, stitch analyze and stitch stream from a shell or coding agent.
Route Aider SEARCH/REPLACE hunks, unified diffs, markdown code blocks and plain-text file sections across the right files in one workflow.
Normalize indentation and check AST/grammar boundaries before writes. Newer guards catch bracket, control-flow and risky seam mismatches.
Open the side-by-side viewer with F10, inspect or revert lines and hunks, and use Ctrl+Z / Ctrl+Y with local .bak snapshots.
Use Shift+F9 for deliberate destination confirmation, F8 to pin a file, or the interactive adjuster to refine ambiguous matches before committing.
Personal Edition can monitor recursively across directories. Folder depth is not a Pro-only feature in the recent GitHub release notes.
No IDE lock-in. Use clipboard monitoring, compose with project context, and take control when a suggested patch needs a closer look.
Use F9 for clipboard monitoring or Shift+F9 for tactical review. The running app makes the current state clear.
Use F7 to build a prompt with relevant source files, directories, and instructions before handing it to your model.
When several files match, anchors are missing, or a replacement fails syntax checks, pick the target, adjust the match, and choose whether to commit or cancel.
