# What is Twin?

Twin is the platform for **building, running, and distributing fully autonomous AI agents**.

Describe an outcome in plain language and Twin will autonomously design an agent that executes the work end-to-end — using APIs when they exist, an embedded browser when they don't, and producing real deliverables rather than just answers.

## What Twin Is — and What It Isn't

Twin is **not a chatbot**. It doesn't just answer questions — it does the work.

Twin is **not a workflow builder** that requires you to predefine every step with nodes and connectors. It takes a goal, figures out the steps, integrates with your tools, executes them reliably, and keeps running over time.

People don't come to Twin to automate a single task once. **They build systems that run repeatedly and improve over time.**

## Why Twin?

<AccordionGroup>
  <Accordion title="Build AI agents — no code required" icon="wand-magic-sparkles" color="#F4D03F">
    Twin lets non-technical users turn simple prompts into production-ready AI agents you can deploy, use internally, or sell to clients.

    Most automation tools fail for the same reason: they push complexity onto the user. You have to host something, configure permissions, manage keys, think about security, keep the workflow from breaking, and then be the on-call engineer when an API changes. **Twin removes all of that.**
  </Accordion>

  <Accordion title="The AI-native alternative to traditional automation tools" icon="bolt" color="#F4D03F">
    Twin delivers the power of traditional automation platforms to non-technical professionals — without the complexity of building and maintaining workflows.

    Traditional tools require you to wire up triggers, map fields, handle errors, and babysit integrations. Twin takes a goal, figures out the steps, and runs them. When something breaks, it adapts. When APIs change, it adjusts. You describe the outcome — Twin handles the rest.
  </Accordion>

  <Accordion title="The setup-free, safe, and scalable alternative to trendy local AI assistants" icon="cloud" color="#F4D03F">
    Twin is simple enough for non-technical builders to get their first autonomous system running in minutes, yet powerful enough to scale into full end-to-end operations without breaking.

    It runs in the cloud with isolated execution environments and managed security — you don't think about servers, ports, or credentials hygiene. Just like people use hosted AI over local models, Twin agents run remotely, safely, and continuously — even when your computer is closed. There is **no setup and nothing to deploy**. You don't spin up a VPS, you don't run a local machine, and you don't manage keys by hand.
  </Accordion>

  <Accordion title="Run your entire business with AI agents" icon="building" color="#F4D03F">
    From marketing operations to lead generation and client services, Twin helps SMBs and agencies automate repetitive work and scale output with intelligent agents.

    Agent builders are the new SaaS builders. The economy will increasingly be powered by autonomous agents rather than traditional software. **Twin is the platform where these new systems emerge and are shared.**

## Key Features

<CardGroup cols={2}>
  <Card title="Autonomous AI Agents" icon="robot" color="#F4D03F">
    Once built, agents run autonomously — triggered by schedules or real-world events — and coordinate across tools and browsers without human supervision.
  </Card>

  <Card title="No-Code" icon="message" color="#F4D03F">
    Describe what you want to achieve. Twin translates it into executable workflows thanks to a brainstorm mode. No code required, ever.
  </Card>

  <Card title="No API Required" icon="globe" color="#F4D03F">
    Agents interact with websites like real users (clicking, typing, navigating), enabling automation even on tools without APIs or without specific API scopes.
  </Card>

  <Card title="Self-Healing & Cheaper Over Time" icon="brain" color="#F4D03F">
    Twin is built for long-term reliability. When integrations throw errors, the agent diagnoses and adapts. When workflows hit edge cases, it learns from them.
  </Card>
</CardGroup>

## What Can You Automate?

Twin can work with **any app** — from the tools your team already uses to systems that traditional automation can't reach. Common use cases include:

<CardGroup cols={3}>
  <Card title="Lead Generation" icon="magnet" color="#F4D03F">
    Research, enrich, and qualify leads from any source
  </Card>

  <Card title="Customer Support" icon="headset" color="#F4D03F">
    Automate ticket triage, responses, and escalation
  </Card>

  <Card title="Finance & Invoicing" icon="file-invoice-dollar" color="#F4D03F">

  <Card title="Reporting & Analytics" icon="chart-line" color="#F4D03F">
    Pull data from multiple sources into dashboards and summaries
  </Card>

  <Card title="Logistics & Operations" icon="truck" color="#F4D03F">

  </Card>

  <Card title="Competitive Intelligence" icon="binoculars" color="#F4D03F">
    Monitor competitor websites, pricing, and job postings
  </Card>
</CardGroup>

And the dozens of repetitive workflows that keep a company alive — if you can describe it, Twin can automate it.

## How Twin Connects to Your Tools

Twin goes beyond pre-built integrations. It connects to your tools in three ways:

<Steps>
  <Step title="Native App Connections — 2,700+ Apps">
    Twin connects to common business tools (spreadsheets, CRMs, databases, messaging) to read data, store results, and trigger downstream actions.
  </Step>

  <Step title="Webhooks & APIs — Your Custom Systems">
    Agents are code-native, so they integrate seamlessly with any external API. You can also trigger agents from your backend via the [REST API](/rest-api).
  </Step>

  <Step title="Websites Without APIs — Twin's Core Strength">
    If a tool doesn't have an API or the right scopes, Twin logs in, navigates the UI, extracts data, and completes actions — just like a human would. See [Web Agent](/web-agent) for details.
  </Step>
</Steps>
