File Upload (PDF, DOCX) | Yes, requires free plan. Agents operate on the local workspace/codebase. That is repo context, not a PDF chat uploader. | Yes, requires free plan. Works on the files in your git repo. That is the codebase, not a PDF uploader. |
Code Execution | Yes, requires free plan. The CLI runs shell commands and coding agents. The IDE agent edits and verifies in the project. | Yes, requires free plan. Automatically lint and test after changes; can fix what those tools report. |
Audio Input | No. No audio-file input is documented. | Partial. Voice-to-code is live mic, not a general audio-file transcriber. |
Canvas / Artifact Editor | Unknown. Overlapping columns disagreed (partial vs yes); left unverified rather than copying a no. | Unknown. Overlapping columns disagreed (no vs partial); left unverified rather than copying a no. |
Screen Sharing / Computer Use | Partial. Browser-in-the-loop agents automate in-page tasks. That is computer-use-like, not a screen-share meeting product. | No. No computer-use product. |
Memory & Context — Tie
| Feature | Google Antigravity | Aider |
|---|---|---|
Persistent Memory | Partial. Custom agents and ~/.gemini/ plus .agents/ configs persist. That is project/user config, not ChatGPT-style memory of you. | Partial. Repo map plus git history persist. Optional conventions files. Not a hosted memory of you. |
Large Context Window | Unknown. Uses Gemini agent models; no token window is published on the Antigravity plans page. | Unknown. Depends on the LLM you connect. No window is published as an Aider product spec. |
Custom Instructions | Yes, requires free plan. Custom Agents are Markdown+YAML under .agents/agents/ or ~/.gemini/config/agents/. | Yes, requires free plan. Config and conventions (comments in-editor, aider config) steer how it edits. |
Conversation History | Yes, requires free plan. Antigravity 2.0 groups conversations into Projects and can schedule messages. | Yes, requires free plan. Terminal chat plus git commits are the history. You can undo with git. |
Integrations — Google Antigravity Wins
| Feature | Google Antigravity | Aider |
|---|---|---|
Web Search / Browsing | Partial. Frontend pitch is browser-in-the-loop agents. That is agent browsing, not a cited search box. | Partial. You can add web pages to the chat as context. That is not a live search box. |
Plugins / Extensions | Yes, requires free plan. Codelab: Antigravity IDE supports local and remote MCP servers; a blog covers IDE Extensions. | No. No plugin marketplace. It is a CLI you script. |
API Access | Yes, requires free plan. Antigravity SDK is a documented Python surface for custom agents on the harness. | No. Aider consumes LLM APIs. It is not a hosted Aider REST generate API. |
Zapier Integration | Unknown. No first-party Zapier app was checked. | No. No Zapier integration is documented. |
Custom GPTs / Bots | Yes, requires free plan. Custom Agents (Markdown) can be selected in the GUI or run via agy --agent. | No. No bot store. |
Real-time Collaboration | Unknown. Repo-shared .agents/ files help teams. Live multiplayer editing was not documented. | No. Single-user CLI. Share via git. |
Live Social Data Integration | No. Not a live social-firehose product. | No. No live social firehose. |

Developer — Google Antigravity Wins
| Feature | Google Antigravity | Aider |
|---|---|---|
Function Calling | Yes, requires free plan. Agents use tools, MCP, shell, and subagents rather than a chat-only reply. | Yes, requires free plan. Edits files, runs linters/tests, and commits. That is tool use, not chat-only. |
Streaming Responses | Unknown. Token streaming in the agent UI is not documented as an API guarantee. | Unknown. Streaming depends on the connected LLM. Not documented as an Aider API guarantee. |
Fine-Tuning | No. You pick Gemini (and on Ultra, third-party) models. No custom-weight training product. | No. You pick a model. Aider does not train weights. |
Embeddings API | No. Not an embeddings API. | No. Repo map is not a public embeddings API. |
Structured Output (JSON) | Unknown. Artifacts exist in the IDE; JSON-schema guarantees were not documented. | No. Output is code diffs/commits, not JSON schema. |
Reasoning / Thinking Mode | Yes, requires free plan. Core agent models include Gemini 3.1 Pro / 3.5 Flash. Ultra adds third-party models. | Unknown. Overlapping columns disagreed (yes vs partial); left unverified rather than copying a no. |
