[FEATURE] Native GUI for JetBrains plugin without CLI dependency or additional installations

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

The JetBrains plugin is a wrapper around the CLI: interaction still happens in a terminal session, not in a native graphical panel comparable to GitHub Copilot. In addition, it requires installing extra tools (Claude Code CLI) on the local machine.

In corporate environments, installing additional standalone tools on company machines is often restricted by IT policy. Teams standardized on GUI-based workflows will not adopt a terminal-based interaction model. Both points currently block enterprise adoption.

Proposed Solution

A fully self-contained JetBrains plugin that:

1. Bundles everything it needs (as the VS Code extension already does) – installable and updatable entirely via the JetBrains Marketplace, no separate installation steps.
2. Provides a native graphical chat panel with inline diff review, file references, and conversation history – comparable to the GitHub Copilot experience in JetBrains IDEs.

Alternative Solutions

Evaluated the current JetBrains plugin: interaction remains terminal-based and requires separate tool installation, which our IT policy does not permit. GitHub Copilot demonstrates that a fully native, dependency-free plugin experience in JetBrains IDEs is feasible.

Priority

High - Significant impact on productivity

Feature Category

Interactive mode (TUI)

Use Case Example

1. Developer opens IntelliJ on a company-managed machine (no additional tool installations permitted).
2. Installs the Claude Code plugin from the JetBrains Marketplace – nothing else.
3. Opens a native Claude panel, requests a refactoring, reviews the diff in the IDE, accepts.
4. This would unblock the rollout to our development team, currently prevented by installation restrictions and GUI-only workflow requirements.

Additional Context

Our team of 40 developers currently uses GitHub Copilot instead, despite its older models delivering noticeably lower output quality. The team would prefer Claude Code for its model quality, but the CLI dependency and required additional installations prevent adoption on company-managed machines. A native, dependency-free JetBrains plugin would directly convert these 40 seats.
