Reviewing AI Diffs in an Editor vs the Terminal

Deep dive into methods for reviewing AI diffs in an editor vs the terminal, exploring side-by-side panels and developer productivity workflows.

Choosing the right environment for reviewing AI diffs in an editor vs the terminal significantly impacts your speed and confidence when merging generated code. Large language models frequently produce substantial blocks of code that require careful inspection before execution. Whether you prefer the stream-based output of a command line or the visual clarity of a graphical editor, the choice dictates how you identify bugs or logic errors introduced by the assistant.

The Terminal Approach to Code Diffs

Many developers start their journey with AI agents directly in the shell. Tools like git provide the foundational logic for terminal-based diffs, typically using the unified diff format. This approach is lightweight and fast, requiring no context switching if you are already running builds or tests in that same window.

Terminal diffs rely on color-coded lines, where green signifies additions and red signifies deletions. While this is efficient for small changes, it becomes difficult to parse when an AI agent refactors an entire class. The lack of syntax highlighting within the diff itself often forces the developer to jump back to their editor regardless, creating a disjointed workflow.

Advantages of Command Line Reviews

The primary benefit of the terminal is its proximity to your execution environment. You can review a change and immediately run a test suite without moving your hands from the home row. For developers who use terminal-based editors like Vim or Neovim, the distinction between the shell and the code view is often blurred, leading to a highly integrated experience.

Limitations of the Unified Diff Format

The greatest weakness of the terminal is verticality. You are forced to scroll through long files while holding the context of the previous lines in your head. When an AI agent suggests changes in multiple places within a file, seeing how those changes interact is difficult when they are separated by hundreds of lines of terminal output.

Reviewing Diffs in a Graphical Editor

Evaluating code changes in a graphical environment offers a side-by-side comparison that terminal tools struggle to match. By presenting the original code on the left and the proposed changes on the right, the cognitive load of tracking modifications is reduced. You can see precisely how a new function call aligns with existing variables.

Most modern editors provide rich syntax highlighting during the review phase. This means that if an AI agent introduces a syntax error, such as a missing closing bracket or a misspelled keyword, it will be immediately flagged by the editor's language server. Terminal diffs generally lack this real-time validation.

Side-by-Side Visual Clarity

The two-pane view is the standard for a reason. It allows you to track the flow of logic across the entire file. When an AI coding agent modifies a loop structure, a side-by-side view shows you exactly which lines were shifted and how indentation has changed. This is critical for languages where whitespace matters, such as Python or YAML.

Integrated Development Environments

IDEs take this a step further by allowing you to accept or reject specific hunks of code. Rather than choosing between all or nothing, you can pick the parts of the AI suggestion that work and discard the rest. This granular control is vital when working with coding agents that might get 90 percent of the task right but fail on a specific edge case.

Hybrid Workspaces and Infinite Canvases

There is a growing trend toward workspaces that do not force a choice between the terminal and the editor. Deska represents this shift by offering an infinite canvas where you can place these tools side by side. Instead of a single window, you have a workspace where you can see the terminal output of an agent and the resulting code changes simultaneously.

In this environment, you can run agents like Claude Code or Codex CLI in a terminal panel and have a code editor panel open right next to it. This eliminates the need to switch tabs or windows. Deska is a free desktop app for Mac, Windows, and Linux that facilitates this by allowing you to place panels anywhere and zoom out to see the entire project state.

Using AI Agents Side by Side

When you run agent threads in Deska, the interaction feels more natural. You can use Ask Deska, the voice and chat assistant, to drive the workspace. For instance, you could ask it to open a specific terminal panel to run a command while you observe the diff in the Monaco editor.

Local-First Security and Performance

A significant concern when reviewing AI-generated code is where that code goes. Deska follows a local-first philosophy. All files, sessions, and code stay on your machine. This ensures that even when you are reviewing complex diffs, your proprietary data is not being stored on external servers during the visualization process.

The Mobile Component of Modern Reviews

The review process does not always happen at the desk. Sometimes you need to monitor a long-running AI task or check the status of a build while away from your computer. Deska provides a mobile app that allows you to monitor and continue your work. Because devices pair directly through a secure relay with no ports exposed, you can review terminal outputs securely on the go.

Frequently Asked Questions

How to see side by side diff in terminal?

While standard git diff uses a unified view, you can use the --word-diff flag or tools like icdiff to see changes side by side in the terminal. However, these still lack the full context and navigation capabilities of a dedicated graphical editor.

Which is better for large refactors by AI?

For large refactors, a graphical editor is almost always superior. The ability to see the architectural changes across multiple files in a structured way prevents the "tunnel vision" that often occurs when reading long terminal outputs. Using workspaces to organize these views can further improve clarity.

Can I use my own API keys for AI diffs?

Yes, Deska supports a BYOK (Bring Your Own Key) model for its lifetime tier. This allows you to use your preferred AI model for generating code while utilizing the Deska canvas for the review process. Subscribers can also opt for managed inference if they prefer not to manage their own keys.

Streamline Your Review Workflow

The best way to decide between a terminal or editor focus is to experience them together. By organizing your terminals and code editors in a shared, zoomable space, you can remove the friction of the review process.
