Modalities — Tie

Modalities: Claude Code compared with Aider
Feature	Claude Code	Aider
Text Input	Yes, requires pro plan. Plain-language prompts drive the agent across the CLI, IDE, desktop, and web.	Yes, requires free plan. You chat in the terminal (or via editor comments) and Aider edits the repo.
Image Upload / Vision	Yes, requires pro plan. Attached photos in the Claude app are passed into the session as vision context.	Yes, requires free plan. Homepage: add images to the chat for visual context and screenshots.
Image Generation	No. Documented as a coding agent that edits files and runs commands, not an image generator.	No. A coding agent, not an image model.
Voice Mode	Unknown. Voice exists on the Claude consumer app; Code surfaces do not document a voice loop of their own.	Yes, requires free plan. Voice-to-code: speak feature requests, tests, or bug fixes.
Video Understanding	Unknown. Not described in the Claude Code overview or mobile client docs.	No. Not a video-analysis product.
Video Generation	No. Not a video generation product.	No. Not a video generation product.
File Upload (PDF, DOCX)	Yes, requires pro plan. Reads and edits the workspace; mobile Remote Control downloads attached files onto the machine.	Yes, requires free plan. Works on the files in your git repo. That is the codebase, not a PDF uploader.
Code Execution	Yes, requires pro plan. Runs shell commands, tests, and git operations as part of the agent loop.	Yes, requires free plan. Automatically lint and test after changes; can fix what those tools report.
Audio Input	Unknown. Audio-file input is not documented for Claude Code.	Partial. Voice-to-code is live mic, not a general audio-file transcriber.
Canvas / Artifact Editor	Yes, requires pro plan. Desktop and VS Code surfaces review diffs visually beside the session.	Unknown. Overlapping columns disagreed (no vs partial); left unverified rather than copying a no.
Screen Sharing / Computer Use	Partial. Claude in Chrome can drive a live web app; that is not full-desktop computer use.	No. No computer-use product.

Memory & Context — Claude Code Wins

Memory & Context: Claude Code compared with Aider
Feature	Claude Code	Aider
Persistent Memory	Yes, requires pro plan. CLAUDE.md plus auto memory that saves learnings across sessions.	Partial. Repo map plus git history persist. Optional conventions files. Not a hosted memory of you.
Large Context Window	Yes, requires pro plan. Indexes the repository; Pro lists a 200k context window for Claude.	Unknown. Depends on the LLM you connect. No window is published as an Aider product spec.
Custom Instructions	Yes, requires pro plan. Project CLAUDE.md, path-scoped rules, and --append-system-prompt steer behavior.	Yes, requires free plan. Config and conventions (comments in-editor, aider config) steer how it edits.
Conversation History	Yes, requires pro plan. Sessions persist across terminal, IDE, web, and mobile, including VS Code history.	Yes, requires free plan. Terminal chat plus git commits are the history. You can undo with git.

Integrations — Claude Code Wins

Integrations: Claude Code compared with Aider
Feature	Claude Code	Aider
Web Search / Browsing	Yes, requires pro plan. Paid Claude plans include web search; Code also pulls live context through MCP servers.	Partial. You can add web pages to the chat as context. That is not a live search box.
Plugins / Extensions	Yes, requires pro plan. MCP servers and the plugin system connect Drive, Jira, Slack, and custom tools.	No. No plugin marketplace. It is a CLI you script.
API Access	Partial. The Agent SDK and Console API keys automate Claude Code; there is no separate public Code REST product besides the Anthropic API.	No. Aider consumes LLM APIs. It is not a hosted Aider REST generate API.
Zapier Integration	Unknown. No first-party Zapier listing was checked.	No. No Zapier integration is documented.
Custom GPTs / Bots	Partial. Skills and sub-agents package workflows; they are not a Custom GPT store.	No. No bot store.

Developer — Claude Code Wins

Developer: Claude Code compared with Aider
Feature	Claude Code	Aider
Function Calling	Yes, requires pro plan. Built-in tools plus MCP and the Agent SDK invoke structured tool calls.	Yes, requires free plan. Edits files, runs linters/tests, and commits. That is tool use, not chat-only.
Streaming Responses	Yes, requires pro plan. The CLI and IDE surfaces stream tokens as the agent works.	Unknown. Streaming depends on the connected LLM. Not documented as an Aider API guarantee.
Fine-Tuning	No. Claude Code runs Anthropic-hosted models; no custom-weight training is offered.	No. You pick a model. Aider does not train weights.
Embeddings API	No. Not an embeddings product.	No. Repo map is not a public embeddings API.
Structured Output (JSON)	Unknown. JSON-schema guarantees are not documented as a Claude Code product switch.	No. Output is code diffs/commits, not JSON schema.
Reasoning / Thinking Mode	Yes, requires pro plan. Runs Claude models with extended thinking for complex work.	Unknown. Overlapping columns disagreed (yes vs partial); left unverified rather than copying a no.
Local Execution	No. The CLI runs on your machine; the model stays on Anthropic (or a third-party provider) infrastructure.	Yes, requires free plan. The program runs on your machine. Models can be local or cloud APIs you configure.
