Start with an issue.
Leave with a plan.

Paste a GitHub issue and PatchIt reads the real repository — README, file tree and source — to give you prioritized first steps, the files that matter, and how to verify your fix.

Features

Everything you need before your first commit

Skip the hours of wandering through an unfamiliar codebase. PatchIt hands you an orientation you can check line by line.

Grounded in real code

Reads the issue, README, file tree and the most relevant source files straight from GitHub before the model says a word.

Prioritized first steps

Up to three concrete, ordered steps — each marked as backed by evidence or still needing verification.

Source-linked files

Every recommended file links to its real location on GitHub, with a confidence level and the reason it matters.

Documented vs. suggested commands

Reproduction and test commands found in the docs are kept clearly apart from ones the model inferred.

Screenshot-aware

Attach a screenshot of a UI bug and Gemma 4 factors what it sees into the plan.

Safe by design

Read-only access to public repositories. Repository code is never executed and screenshots are never stored.

How it works

From issue link to plan in under a minute

  1. 1

    Paste two links

    A public GitHub repository and one of its issues. Optionally attach a screenshot of the bug.

    github.com/owner/repo/issues/123

  2. 2

    PatchIt reads the repository

    It fetches the issue, README and file tree, then samples the source files most likely involved.

    README · tree · 5 source files

  3. 3

    Get your contribution plan

    Gemma 4 turns that evidence into first steps, files to read, and commands to reproduce and test.
