What is Morph?

Morph Fast Apply is a tool that you give to your AI agent that allows it to edit code or files. When building AI agents that edit code or files you have 3 options:
  1. Rewrite entire files (slow, expensive, loses context, hallucinates updates) - 100+ seconds per file edit
  2. Use search-and-replace (brittle, fails on whitespace/formatting, needs self correction loops) - 86% accurate with Claude 4 Sonnet: 35s per file edit
  3. Fast Apply via an edit_file tool (fast, accurate, semantic) - 98% accurate with Morph + Claude 4 Sonnet: 6s per file edit

​
Why You Need It

Current AI code editing is broken. Agents either:
  • Rewrite entire files (slow, expensive, loses context)
  • Use search-and-replace (brittle, fails, needs self correction)
You lose customers while your agents are fixing patch errors. Fast Apply solves this. Your agent uses an edit_file tool that writes lazy edit snippets, and Fast Apply handles the merging - the same way Cursor does it. Fast, Reliable Edits every time

​
How It Looks in Your Code

  1. Give your agent an edit_file tool - It generates abbreviated edit snippets in this tool call
  2. Call Morph’s API inside the tool - We merge the edit with the original file FAST, using our specialized models
  3. Write the result - Get the merged code back and save it to your filesystem
