Modalities — Google Antigravity Wins

Modalities: Google Antigravity compared with Tabnine
Feature	Google Antigravity	Tabnine
Text Input	Yes, requires free plan. Agents are driven by text prompts in the desktop command center, IDE agent panel, and CLI.	Yes, requires plus plan. IDE chat plus code completions. CLI agent on the Agentic Platform.
Image Upload / Vision	Unknown. Vision attach in the agent panel was not confirmed on the product homepage or plans doc.	Unknown. Vision attach in IDE chat was not confirmed on the pricing page.

Voice Mode	No. No conversational voice loop is documented.	No. No conversational voice loop is documented.
Video Understanding	No. Not a video-analysis product.	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 free plan. Agents operate on the local workspace/codebase. That is repo context, not a PDF chat uploader.	Yes, requires plus plan. Context Engine connects to Git hosts. Completions use the current file/repo.
Code Execution	Yes, requires free plan. The CLI runs shell commands and coding agents. The IDE agent edits and verifies in the project.	Partial. Agentic workflows and CLI can change code, test, and open PRs. Completions-only is not a sandbox executor.
Audio Input	No. No audio-file input is documented.	No. No audio-file input is documented.
Canvas / Artifact Editor	Unknown. Overlapping columns disagreed (partial vs yes); left unverified rather than copying a no.	Unknown. Overlapping columns disagreed (no vs yes); 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 — Tabnine Wins

Memory & Context: Google Antigravity compared with Tabnine
Feature	Google Antigravity	Tabnine
Persistent Memory	Partial. Custom agents and ~/.gemini/ plus .agents/ configs persist. That is project/user config, not ChatGPT-style memory of you.	Yes, requires pro plan. Context Engine plus Coaching Guidelines persist org standards. Zero code retention otherwise.
Large Context Window	Unknown. Uses Gemini agent models; no token window is published on the Antigravity plans page.	Unknown. Depends on the connected LLM. No window is published as a Tabnine spec.
Custom Instructions	Yes, requires free plan. Custom Agents are Markdown+YAML under .agents/agents/ or ~/.gemini/config/agents/.	Yes, requires plus plan. Coaching Guidelines and governance controls define boundaries and behavior.
Conversation History	Yes, requires free plan. Antigravity 2.0 groups conversations into Projects and can schedule messages.	Yes, requires plus plan. IDE chat is a conversation surface. Auditability of usage is listed.

Integrations — Google Antigravity Wins

Integrations: Google Antigravity compared with Tabnine
Feature	Google Antigravity	Tabnine
Web Search / Browsing	Partial. Frontend pitch is browser-in-the-loop agents. That is agent browsing, not a cited search box.	Unknown. MCP can reach external services. A first-party web search toggle was not confirmed.
Plugins / Extensions	Yes, requires free plan. Codelab: Antigravity IDE supports local and remote MCP servers; a blog covers IDE Extensions.	Yes, requires plus plan. Works in major IDEs. Agentic plan adds MCP (Jira, Confluence, Docker, CI).
API Access	Yes, requires free plan. Antigravity SDK is a documented Python surface for custom agents on the harness.	No. You may bring your own LLM endpoint. Tabnine is not a public generate REST API.
Zapier Integration	Unknown. No first-party Zapier app was checked.	Unknown. No first-party Zapier app was checked.
Custom GPTs / Bots	Yes, requires free plan. Custom Agents (Markdown) can be selected in the GUI or run via agy --agent.	Partial. Coaching Guidelines specialize agents. Not a GPT Store.
Real-time Collaboration	Unknown. Repo-shared .agents/ files help teams. Live multiplayer editing was not documented.	No. Team admin/analytics, not a multiplayer chat session.
Live Social Data Integration	No. Not a live social-firehose product.	No. Not a live social-firehose product.
Live Citation Mapping	No. Not a cited-search product.	No. Not a cited-search product.

Developer — Tabnine Wins

Developer: Google Antigravity compared with Tabnine
Feature	Google Antigravity	Tabnine
Function Calling	Yes, requires free plan. Agents use tools, MCP, shell, and subagents rather than a chat-only reply.	Yes, requires pro plan. Agents use MCP tools (git, tests, linters, Jira, APIs).
Streaming Responses	Unknown. Token streaming in the agent UI is not documented as an API guarantee.	Yes, requires plus plan. Inline completions stream into the editor as you type.
Fine-Tuning	No. You pick Gemini (and on Ultra, third-party) models. No custom-weight training product.	No. You connect org context and optionally your LLM. No Tabnine custom-weight training SKU is listed.
Embeddings API	No. Not an embeddings API.	No. Context Engine is not a public embeddings API.
Structured Output (JSON)	Unknown. Artifacts exist in the IDE; JSON-schema guarantees were not documented.	Unknown. JSON-schema guarantees were not documented on the pricing page.
