Linda
Install

Quickstart

Your first agent in five minutes.

Linda runs entirely in the browser. No backend to stand up, no build pipeline to learn — add the SDK, point it at a form, bring your own key, and the agent starts filling fields.

All install paths → See it live

The short version: add Linda to a page, describe the fields you want collected, set a provider + key, and call linda.attach(). The model reads your live page as a virtual filesystem and writes its answers back into your <input> elements — no server runtime required.

  1. 1. Add Linda

    Pick the shape that fits your stack. The script tag is the fastest path — a single UMD bundle (~34 KB gzipped) with zero build step. For app code, install @linda/core or, in React, @linda/react. 

    <script src="https://unpkg.com/@linda/script/dist/linda.js"></script>

<form
  data-linda
  data-linda-config="/configs/signup.json"
  data-linda-provider="anthropic"
  data-linda-model="claude-sonnet-4-6"
  data-linda-key="sk-ant-..."
>
  <input name="email" />
  <input name="company" />
  <input name="team_size" />
</form>

  2. 2. Describe the target

    Linda needs to know what it's collecting. With the script tag, add data-linda to a <form> and let the field names speak for themselves. In code, pass a config with a dataPoints array — each entry is a field name plus the question the agent should ask. The live DOM is mounted at /page in the virtual filesystem, so the model can read surrounding context, not just the fields.

  3. 3. Bring your own key

    Set a provider and an apiKey. Anthropic Claude is the default; OpenAI, Groq, OpenRouter, and local Ollama are one line away. See the providers guide for the exact transport config per model.

    Shipping to production? Don't put a raw key in the browser. Drop in @linda/server — a ~1 KB Node proxy that streams responses over SSE and keeps the key server-side. See Security.

  4. 4. Attach

    Call linda.attach() (or render <LindaForm> in React). Linda injects a style-isolated Shadow-DOM chat overlay, runs the tool loop, and fills your inputs as the conversation progresses. Wire up hooks to validate or veto writes, and add skills for capability-gated flows like KYC or payment.

Where to go next

Ship an agent-driven flow this afternoon.

Install Linda, paste a config, and your form turns into an agent that fills its own inputs.
