Live demos

See Linda actually work.

Paste your API key in the bar above. These five demos run the real SDK in your browser against the provider you choose. No server in between, no telemetry, no key forwarding.

Heads up: each demo makes a real LLM call with your key. Expect ~$0.01–0.05 per run depending on the demo and model. We recommend a fresh key with a low monthly cap for trying things out.

Conversational signup form

~$0.01

The canonical 10-second script tag. Linda turns a 5-field form into a friendly chat that fills the inputs one at a time, then fires onComplete.

  • [data-linda]
  • PageMount
  • DataPoints
  • onComplete

In-page copilot

~$0.02

A mock SaaS pricing page with Linda mounted as a sidebar companion. Reads /page/dom.html. Multi-agent (Researcher + Summarizer) + a live VFS inspector.

  • VFS
  • multi-agent
  • linda.observe()
  • /host/* mount

Browser-side PDF Q&A

~$0.02

Drop a PDF, ask questions. pdf.js parses in the browser via @linda/parsers-pdf (lazy from esm.sh). The PDF never leaves your tab.

  • @linda/parsers-pdf
  • lazy WASM
  • no upload

Extract a table → CSV

~$0.005

linda.extract() against a live HTML table. Returns typed JSON or CSV. No screen-scraping — the agent reads the DOM directly.

  • linda.extract()
  • PageMount
  • schema validation

Multi-agent checkout rescue

~$0.03

A mock checkout with two agents. The default intake agent walks you through. On exit-intent (mouse to top), the rescue agent takes over with a different persona.

  • multi-agent
  • onExitIntent
  • handoff
  • scope-gated

How the demos work

  1. You set a key in the bar above. We persist it to localStorage under your origin, scoped per provider. Linda never sees your key — your browser passes it directly to the provider you picked.
  2. Each demo page lazy-loads /linda.js (the real SDK UMD, ~107 KB) on first mount.
  3. The demo instantiates new Linda({...}) with your key and runs the configured agent loop on the demo's DOM.
  4. When you close the tab, the SDK bundle is cached but the conversation state is gone. Your key persists until you clear it.

Why no Linda-hosted demos?

We could host demos with our own keys and rate-limit. We don't because the value of Linda is "no SaaS in the middle" — and a hosted demo would contradict that. BYOK keeps the demos honest about what Linda is: a runtime, not a service.

Don't have a key?

Each provider has a free or low-cost tier:

  • Anthropic — sign up at console.anthropic.com and add $5 credit. That's ~500 demo runs of Sonnet 4.6.
  • OpenAI — sign up at platform.openai.com and add $5. Use gpt-4o for the same UX.
  • Ollama Cloud — sign up at ollama.com/cloud. Free tier available; OpenAI-compatible endpoints, so Linda's OpenAI transport runs against them via a custom base URL.
