Antigravity: Four Interfaces, One Agent Framework

Antigravity is Google's agentic development platform, and its core value is that it doesn't lock you into a single window. It offers four ways to work—pick whichever fits your habits.

• Antigravity 2.0: A standalone desktop app supporting macOS, Windows, and Linux. Great for visual task orchestration and asynchronous workflows, with multi-project workspace management, visual artifacts like diffs, UI screenshots, and browser recordings, plus scheduled background tasks and voice input.
• CLI: A lightweight terminal interface (command: agy), ideal for terminal lovers, remote SSH operations, and quick edits. Keyboard-driven, near-zero footprint, with settings shared with the desktop app.
• IDE: A full AI-native editor built on open-source VS Code, with the Agent manager and text editor side by side—great as your primary coding environment.
• SDK: A Python programming framework for registering tools, defining safety policies, and spawning agents in code—ideal for building custom agents and automation pipelines.

The Dual-Wielding Workflow

If you're already comfortable with VS Code or Cursor, you don't need to switch entirely. The recommended approach is dual-wielding: keep your usual editor for daily writing and tweaks while running Antigravity 2.0 or the CLI in parallel for cross-file refactors, background tests, and long-running agent tasks. Same goes for those prototyping in Replit in the browser—leave quick experiments to Replit and hand the heavy lifting to Antigravity.

To install: download the version for your system from antigravity.google, sign in with a free Google account, and open your project folder. CLI users can run the install script—on macOS/Linux use curl -fsSL https://antigravity.google/cli/install.sh | bash, on Windows PowerShell use irm https://antigravity.google/cli/install.ps1 | iex. Running agy for the first time will trigger browser OAuth authentication.

Three Copy-Paste Prompts

Scan this repo. Summarize the stack in 5 bullets, list the top 3 risks for a solo builder, and propose a 1-hour fix list. Do not change files yet.

Add a /health JSON route if missing. Keep the change minimal, write a short curl check, and show me the diff before applying anything destructive.

Create or update AGENTS.md with project conventions: never commit .env, prefer small PRs, explain folder layout in under 40 lines.

Antigravity's "agentic coding" means letting an AI agent autonomously handle a whole chain of actions—reading the codebase, planning changes, executing commands, verifying results—with minimal step-by-step human intervention, rather than just doing single-turn completions. What sets it apart from traditional coding assistants is task-level autonomy and tool-calling capability, usually accompanied by safety mechanisms like file diff review, sandboxed execution, and permission policies. The SDK section's mention of "registering tools and defining safety policies" is precisely how developers constrain what the agent can reach, preventing it from performing destructive operations when unattended; "asynchronous workflows" and "long-running background tasks" are built on this same model, making it well-suited for time-consuming work like cross-file refactoring and batch testing.

Stitch: From Text or Sketches to UI

Stitch is Google Labs' AI-native UI design tool, powered by Gemini models. It skips the blank canvas—you can describe requirements with text or voice, or upload sketches, wireframes, or screenshots to get a structured, responsive interface in seconds.

The tool has two modes: the standard mode focuses on fast text-to-UI, while the experimental mode is stronger at sketch-to-UI. Use cases include mobile app shells, web dashboards, landing pages, and multi-screen drafts like splash → sign-up → home → settings.

Export Paths

Stitch's interfaces can flow in several directions: copy to Figma for editable layers and Auto Layout; export HTML/CSS/Tailwind code into VS Code or Cursor; drop the HTML or a short design.md into Bolt.new or Lovable to turn static UI into a running app with state; connect to Google AI Studio or Firebase Studio for auth, Firestore, and backend; or paste the layout brief into v0 to generate React components.

Prompt Writing Tips

Clear hierarchy, color, and layout rules are far more effective than "make it look good." The original article gives five examples covering a dark mobile crypto dashboard, a web SaaS analytics table, a health app onboarding flow, an e-commerce product detail page, and a telehealth video call interface. Here's the crypto dashboard example:

Create a modern mobile iOS dashboard for a crypto tracking app called 'Aura Crypto'.
Layout:
- Top Bar: Avatar icon on the left, notification bell with badge on the right.
- Hero Card: Dark slate background with a subtle neon green gradient border. Show total balance '$42,580.12' in 32px bold text, with a '+4.2%' pill badge.
- Quick Actions: Row of 4 circular icon buttons ('Send', 'Receive', 'Swap', 'Buy').
- Horizontal Scroll Section: 'Watchlist' showing mini-sparkline charts for BTC, ETH, and SOL.
- Bottom Navigation: 4 tabs ('Home', 'Markets', 'Analytics', 'Profile') with high-contrast active state.
Theme: Deep dark mode (#0D1117 background) with neon accent colors.

The idea of replacing vague adjectives with structured area descriptions can be directly applied to the other four scenarios.

Stitch's export to Figma "Auto Layout" refers to Figma's constraint-based automatic layout system: elements are arranged in rows or columns with configurable spacing, padding, and fill rules, and child elements reflow automatically when the container resizes. When AI-generated interfaces land as Auto Layout, designers can add, remove, and modify components just like working with native design files, instead of facing a pile of scattered, absolutely-positioned layers. This also explains why "editable layers + Auto Layout" is seen as the benchmark for Stitch export quality—it determines whether the generated output can flow smoothly into real design collaboration workflows rather than being usable only as a static reference image.

Pomelli: Paste a URL, Generate a Brand Kit and Campaigns

Pomelli, built jointly by Google Labs and DeepMind, targets small and medium businesses without a full design team. The core flow is straightforward: enter a website URL, and it scrapes brand information to generate a mood board and style analysis—covering color palette, tone, font cues, and visual direction—then starts generating marketing campaign assets.

The steps: sign in and enter the URL, wait for the brand analysis to complete, create a campaign and choose an image ratio (square, story, landscape, etc.), enter your generation request, then fine-tune with simple instructions like swapping backgrounds, changing product images, or matching holiday themes. The tool also offers templates for product mockups, Mother's Day, Father's Day, seasonal promotions, and launch teasers.

The original author suggests using OmniSocials for scheduling and publishing after generation—one workspace to manage posts across Facebook, Instagram, Pinterest, LinkedIn, YouTube, TikTok, X, Threads, Bluesky, and more. Here's a sample prompt:

Brand site: https://your-business-site.example
Campaign: Summer launch — 3 square posts + 2 story frames.
Tone: friendly, clear, no hype.
Instructions: Keep brand colors from the site analysis. Swap background to soft daylight. Add 'Free shipping this week' as secondary text on one square.

Google Flow: An AI Studio for Stories and Video

Flow is Google's AI creative studio for cinematic scenes, storyboards, image-to-video, and narrative shorts. Multimodal models (including Gemini-class models and the Veo video engine) let you combine text, stills, and camera control into continuous shots. The core operation is image-to-video with camera physics, supporting dolly, pan, orbit, and chaining shots to maintain lighting and character consistency.

Image-to-video prompts can be written across four dimensions: subject, motion, atmosphere, and camera. For example, a character motion scene:

Subject: The character in the input image.
Motion: Slow orbit camera shot moving in a tight circular arc around the subject. The subject turns their head slowly toward the camera and settles with a subtle smile blooming.
Atmosphere: Soft golden-hour sunlight shifts naturally across their face, fabric of the coat sways gently in a light breeze.
Camera: Eye-level, shallow depth of field, blurred background bokeh.

The same applies to environment and lighting transition scenes—describe dolly movement, drifting mist, light refraction, and swaying leaves, paired with a mood direction like "inspiring, serene, atmospheric."

Flow Music: A Music Studio Powered by Lyria 3.5

Flow Music is the companion music studio where you can converse with an AI producer, generate tracks from about 30 seconds to several minutes using text, lyrics, images, or audio references, and direct music video production. A free Google account is all you need to start.

According to Google's official blog, Flow Music is rolling out Lyria 3.5, DeepMind and Labs' latest music generation model. The officially highlighted upgrades include: richer, more natural melodic structure; improved lyric quality with better prompt adherence and awareness of verse-chorus structure; more realistic vocal expressiveness and pronunciation; and easier control over tempo and duration.

In the studio, you can conversationally adjust arrangements (tempo, instruments, vocals), use structural tags like [Verse 1] and [Chorus] to guide song form, and auto-generate cover art. Sample prompt:

Style: Synthwave, Cyberpunk, 80s Retrowave
Tempo: 115 BPM
Instrumentation: Analog poly-synths, heavy sidechained bassline, gated reverb snare, soaring lead guitar.
Mood: Energetic, nostalgic, late-night drive.

[Intro]
(Atmospheric synth pads building with slow sidechain pulsing)

[Verse 1]
Neon lights reflecting on the rainy street below,
Chasing digital shadows where the city lights glow.
Engine revs in silence, counting down the time.

[Chorus]
We run through the static, fading in the light,
Speeding through the grid into the endless night!

Three-Tool Combo: Image → Video → Soundtrack

The original article's recommended full pipeline has three steps: first generate a 35mm cinematic still in Flow of a futuristic astronaut standing on an alien dune, then turn it into video with a slow crane shot prompt, and finally generate a cinematic ambient sci-fi score in Flow Music to lay under the clip. This kind of combined workflow is what people in the community are actually trying.

How the Five Tools Divide the Work

Antigravity writes and refactors code, Stitch invents UI and exports to Figma, code, or Bolt, Lovable, v0, Pomelli analyzes brands from URLs and produces marketing assets, Flow turns stills into motion, and Flow Music scores your stories. All five tools share the same free Google account and can be chained together by project stage.

The original article notes: screenshots and marketing images come from Google's official pages for editorial use only, and Google was not paid; Replit and OmniSocials links are referral/affiliate links; product availability and free quotas may change.

Which prompt do you want to try first? Feel free to share your results in the comments.

The recurring term "vibe coding" refers to a way of working where developers describe intent in natural language while AI handles most of the code output, with humans acting more as reviewers and direction-setters. It lowers the barrier from idea to runnable prototype, but brings new problems too: generated code correctness needs verification, quality degrades with overly long context, and security and dependency risks need human oversight. That's why Antigravity's prompts in this article deliberately emphasize "don't change files yet" and "show me the diff before destructive operations," and why Stitch emphasizes structured descriptions over "make it look good"—these are the practical points that keep vibe coding under control.
