IDEA-Codex Bridge

Select code in JetBrains IDEs and send precise references to Codex App in one click

Problem

Developers using Codex App alongside their IDE must manually copy file paths, count line numbers and switch to the Codex window to paste context. After selecting multiple lines the reference format is error-prone, breaking flow and making the whole loop tedious.

Solution

A JetBrains IDE plugin that adds a 'Send to Codex App' action in the editor toolbar and context menu. It opens the current project in Codex App with one click, and when code is selected it automatically attaches the file path and exact line range. The reference is only inserted into the input box, not auto-sent, so users can add more context.

Users

Developers who use JetBrains IDEs and Codex App together, especially those who frequently explain context to AI assistants.

MVP

Add send buttons to the IDEA toolbar and context menu; support one-click opening of the current project in Codex App; auto-generate file-path#startLine-endLine references when code is selected; append the reference to the input box without auto-sending; support macOS and Windows first.

Revenue

Free basic features; paid annual subscription or one-time license for multi-project workspaces, reference templates and history; also functions as a funnel into a broader AI coding toolkit.

Why now

The combination of Codex App and JetBrains IDEs is growing fast, but no official deep integration exists. Plugin development is low-effort and indie developers can launch quickly and gain organic traffic from the plugin marketplace.
