What Composite does

Composite Sciences, Inc. operates an AI-powered browser automation platform designed to eliminate repetitive digital tasks for knowledge workers. The product is delivered as a browser extension compatible with Chrome, Edge, and Arc, alongside native desktop applications for Windows 10/11 and macOS (both Apple Silicon and Intel architectures). Technically, the platform combines vision models, DOM analysis, and accessibility-tree parsing to perceive web pages, accepts natural-language task descriptions, and executes multi-step browser actions autonomously through a multi-model AI routing architecture that sources from multiple providers rather than locking into a single ecosystem. A proprietary site-specific hints layer provides curated guidance for automating complex interfaces such as Google Sheets. All execution runs locally on the user's device with zero data retention by AI sub-processors, addressing enterprise privacy requirements.

The company was founded in 2025 by Yang Fan Yun (former Uber product manager) and Charlie Deane, and is headquartered at 425 2nd Street in San Francisco. Composite employs a product-led go-to-market motion anchored by a free beta tier offering 5,000 AI requests per month with no credit card required, and a Pro subscription tier priced at $20/month providing three times the AI request volume, enterprise-grade security, and priority support. Custom enterprise plans are available via direct sales. Within roughly two months of launch, the company reported thousands of users across hundreds of organizations, with named logos spanning Google, Meta, Tesla, Salesforce, Uber, Bain & Company, and Reddit. Composite closed a $5.6 million seed round in September 2025 led by Nat Friedman and Daniel Gross (NFDG), with participation from Menlo Ventures and Anthropic's Anthology Fund. The company is pre-revenue with no publicly disclosed financials.

Core offering

Composite is a browser-based AI automation platform that runs locally inside users' existing browsers (Chrome, Edge, Arc) as an extension, with desktop applications for Windows and macOS. Users describe tasks in natural language, and an AI agent autonomously clicks, types, and navigates across any website the user has access to—handling repetitive workflows such as Jira backlog triage, CRM updates, recruiting coordination, expense submission, and vendor assessment—that traditional automation tools cannot reach because the underlying sites lack APIs. The platform uses a multi-model AI routing architecture, processes pages via vision models plus DOM/accessibility tree analysis, learns from user behavior to proactively suggest automations, and runs in background tabs with multi-threaded execution.

Product overview

Composite is a browser-based AI automation platform that combines a browser extension (for Chrome, Edge, and Arc) with downloadable desktop applications for Windows and macOS. The core product is an AI-powered browser autopilot that learns user workflows and automates repetitive digital tasks. The platform operates as a unified offering with two pricing tiers: a Free tier (5,000 AI requests/month) and a Pro tier ($20/month with 3x requests and enterprise security). Key features include site-specific hints that handle complex web interfaces, multi-model routing across various AI providers, local browser execution for privacy, and multi-threading support for running up to five concurrent automation tasks. The company positions itself against both hosted AI browsers and traditional workflow automation tools.

Differentiator

Problem solved

Functional benefit

Products and services

• Composite Browser Extension AI-powered browser extension for Chrome, Edge, and Arc that autonomously automates repetitive professional browser tasks. Users describe tasks in plain language via a Spotlight overlay (Ctrl+Shift+Space); the agent executes by clicking, typing, and navigating across any site the user has access to, learning from behavior and running in background tabs. Target users are individual knowledge workers and professionals at SMBs and enterprises.
• Composite Desktop Application (Windows) Native Windows 10/11 desktop application delivering the full Composite browser automation experience with platform-native integration. Targeted at Windows knowledge workers who prefer a desktop client over a browser extension.
• Composite Desktop Application (macOS) Native macOS desktop application delivering the Composite browser automation experience, available in two architecture builds (Apple Silicon for 2020+ Macs and Intel for 2019 and earlier Macs). Targeted at macOS-based knowledge workers who prefer a desktop client.

Direct peers

• Anthropic (Claude for Chrome): Anthropic is both an investor in Composite and a direct competitor via Claude for Chrome, its own AI browser-agent extension. Both products target the same persona (knowledge workers) with autonomous browser automation driven by Claude, making Anthropic the single most relevant peer and the most consequential competitive threat.
• Perplexity (Comet browser): Perplexity launched Comet, an AI-native browser with built-in agentic task automation, directly competing with Composite's browser-agent approach. Both target knowledge workers who want AI to perform web-based tasks autonomously, though Comet requires browser migration while Composite works in existing browsers.
• The Browser Company (Dia): The Browser Company launched Dia, an AI-native browser with embedded agentic capabilities, and is one of the companies Composite explicitly compares itself against on its website. Both aim to automate knowledge-work tasks via AI in the browser, differing primarily on migration model.
• Bardeen: Bardeen is a direct competitor offering AI-powered browser automation for repetitive workflows, with strong traction among SDRs, recruiters, and ops teams — overlapping directly with Composite's primary persona. Both pursue PLG-led adoption and horizontal use-case expansion in the browser.
• Magical: Magical is a browser extension that automates repetitive tasks like data entry, form filling, and text expansion across web apps. It targets the same knowledge-worker pain point (tab-switching and manual busywork) as Composite, though with a more rules-based rather than fully agentic approach.

Broad incumbents

• OpenAI (Operator / ChatGPT agent): OpenAI ships Operator and broader ChatGPT agent capabilities that automate browser-based tasks using its own foundation models. As the leading AI lab with massive distribution and direct model ownership, OpenAI is the broadest incumbent threat to standalone browser-agent startups like Composite.
• UiPath: UiPath is the established leader in robotic process automation (RPA), addressing the same broad problem of automating repetitive digital work that Composite targets. UiPath's strength is enterprise-grade attended/unattended bots; Composite's is consumer-grade browser-agent UX.

Emerging players

• Adept AI: Adept builds AI agents that operate software interfaces (browsers and enterprise apps) on behalf of users, sharing Composite's core thesis that AI agents should act inside existing software rather than replacing it. Adept is more enterprise-focused and raises substantially more capital per round.
• Reworkd AI: Reworkd builds AI agents that automate web-based data extraction and workflow tasks, sharing Composite's vision of agentic browser automation. As a smaller, earlier-stage competitor, it represents the same emerging category but with a narrower data-extraction focus.

Others

• Zapier: Zapier is the dominant workflow automation platform for connecting SaaS apps without code. While Zapier requires explicit workflow building (Composite's key contrast) and does not handle sites without APIs, both ultimately compete for the same automation budget inside knowledge-worker organizations.
