Overview
Chat with Code is Parsaa’s core surface. Open Parsaa alongside Xcode and have a natural-language conversation about your code. Parsaa observes Xcode through the macOS Accessibility API — it can see your open files, the current selection, project structure, and build errors — then uses its built-in tools to act on your project.Parsaa runs as a native companion app, not a plugin or extension. The chat window sits beside Xcode and adapts to its width (compact and wide layouts).
How It Works
Parsaa observes your Xcode session
Using the macOS Accessibility API, Parsaa detects the active project and can capture the current editor selection.
You ask a question
Type a request in natural language. You can attach files, capture the Xcode selection, @mention a sub-agent, or run a workflow from the context picker.
Parsaa gathers context
Parsaa collects the relevant context — focused file, attached files, indexed code — and sends it to your chosen model.
The Chat Interface
Message list
User messages, assistant blocks, tool-call chips, and reasoning rows in one scrolling thread.
Status pill
A floating badge shows streaming, thinking, or error states while a response is generated.
Reasoning & thinking
Toggle Reasoning Mode and the visible thinking display from the footer. Reasoning effort is selectable in the composer.
Activity tray
A docked panel surfaces the active plan and live to-do list above the input.
Message Queueing
You don’t have to wait for the agent to finish. Send a follow-up message while a turn is still processing and Parsaa queues it — queued messages are sent in order, one after each turn completes. Useful for stacking up “then do X, then Y” without losing your train of thought.Attaching Context
Your messages can carry more than text. From the context picker you can:- Capture the Xcode selection — pull the highlighted code in as a chip
- Attach files — add any file in the project by path
- @mention a sub-agent — delegate part of the work to a specialized agent
- Run a workflow — kick off a multi-step workflow instead of a plain message
Built-in Tools
During a conversation the agent autonomously calls tools to help you. You don’t call them directly — the agent decides based on your request.| Category | Example Tools |
|---|---|
| Read & navigate | file_tree, read_files, grep_project, globs, search_file_names, get_symbol_info, semantic_search |
| Edit | create_file, edit_file, rewrite_file, delete_file, apply_code |
| Build & run | compile_app, run_app, test_app, stop_app, list_schemes, list_simulators, show_build_settings |
| Git | git_status, git_diff, git_commit |
| Plan & extend | plan_create, plan_status, todo_write, skill, mcp_tool, web_search, web_fetch |
Example Use Cases
Understand your codebase
Understand your codebase
“Explain how authentication works in this project” — Parsaa reads the relevant files, traces the flow, and explains how the pieces fit together.
Make changes across files
Make changes across files
“Add a loading spinner to the HomeView” — Parsaa finds the right files, writes the SwiftUI code, and updates related view models or state.
Debug issues
Debug issues
“Find and fix the crash in the networking layer” — Parsaa searches, analyzes, and proposes a fix, or applies it after your approval.
Refactor code
Refactor code
“Refactor this view model to use async/await” — Parsaa rewrites it with modern concurrency and updates call sites as needed.
Privacy
In Private Mode, nothing is retained past the request and response. In Training Mode you control exactly what is stored with per-category toggles. See Privacy & Data.
