description	Use when asked to add or manage Copy2LLM, a portable website-to-AI context layer for plain HTML, React, Next.js, Astro, or Framer; configure capture, Context Cart, extraction boundaries, handoff targets, styling, or troubleshoot extraction and display.

copy2llm — install and manage the "Copy to LLM" button

Overview

copy2llm (copy.computer) is the portable context layer between websites and AI. Readers can capture a page, selection, or section; review multiple sources locally; then copy, download, or send the bundle to ChatGPT, Claude, Perplexity, Grok, or a custom endpoint. Fully client-side: no backend, API key, or account.

Pick an install path

Situation	Use
Any site, zero build	<script> snippet
React / Next.js	copy2llm-react
Non-React JS, imperative mount/destroy	copy2llm-widget
Framer site	official plugin
Markdown extraction only, no UI	copy2llm-core

Script tag (any stack)

Place before </body> (Next.js: root layout via <Script strategy="lazyOnload">; Astro: base layout):

<script src="https://copy.computer/copy2llm.js" defer
        data-position="bottom-right" data-theme="auto"></script>

The hosted snippet is unversioned and always latest (cached ≤ 5 min). Add data-automount="false" to take control and mount yourself via window.copy2llm.mount(options, target).

React

npm i copy2llm-react   # react >= 17 peer dependency

import { CopyToLLM } from "copy2llm-react";

<CopyToLLM position="bottom-right" theme="auto" />

Mounts the widget on mount, tears it down on unmount. position="inline" renders an in-flow anchor where placed; any other position mounts onto document.body.

Imperative (non-React)

import { mount } from "copy2llm-widget"; // npm i copy2llm-widget

const handle = mount({ position: "bottom-right", theme: "auto" });
handle.destroy(); // remove

Framer

Install the official plugin from the Framer marketplace: https://www.framer.com/community/marketplace/plugins/copy-to-llm/. It intentionally remains on the classic single-page copy/handoff flow. Do not promise Context Cart, exclusion selectors, usage events, or the full option table for Framer.

Options

Script data-* attributes, React props, and mount() options share the following configuration unless noted:

Option	Script attribute	Values	Default
position	data-position	bottom-right bottom-left top-right top-left inline	bottom-right
theme	data-theme	auto light dark — auto matches the host site, falls back to the OS, stays live	auto
bg	data-bg	any CSS color	from theme
text	data-text	any CSS color	auto-contrast from bg
font	data-font	sans serif mono	sans
radius	data-radius	sharp rounded pill or any CSS length	rounded
label	data-label	primary button text	Copy as Markdown
prompt	data-prompt	lead-in text sent to the LLM before the page's Markdown on the Open in… actions (e.g. "Summarize this API reference"); not available in the Framer plugin	Here's a web page as Markdown — help me work with it:
items	data-items	comma-separated from copy pick context view chatgpt claude perplexity grok; first is primary	all
header	data-header	true/false — prepend a title + source header to the Markdown	true
content	data-content	CSS selector for the extraction root	auto (Readability)
exclude	data-exclude	CSS selectors removed before extraction; [data-copy2llm-ignore] is always removed	none
endpoints	data-endpoints	JSON array of { "label", "href" } custom LLM targets	none
onEvent	—	React/widget callback with privacy-safe action metadata; script users observe copy2llm:action	none

Custom endpoint href is a deep-link template: {q} is replaced with the page's Markdown (appended if the template has none; pages too long to inline fall back to a clipboard paste):

data-endpoints='[{"label":"Open in Acme AI","href":"https://acme.ai/?q={q}"}]'

Manage

• Update: the script tag auto-updates (hosted, unversioned). npm installs update normally (npm update copy2llm-react).
• Remove: delete the script tag / component; imperative mounts: handle.destroy().
• Reconfigure: change the attributes/props. Context Cart sources use same-origin sessionStorage, persist across navigation in the current tab, and clear when the tab session ends.
• Interactive configurator with live preview: https://copy.computer/#install

Verify

Load the page: the button appears at the configured position. Verify Copy as Markdown, then choose Add to AI context and confirm the source appears in the review sheet. Long handoffs must either copy the full Markdown before opening the AI or show the Markdown preview; they must never open an empty prompt silently.

Common mistakes

• data-endpoints must be valid JSON — wrap the attribute value in single quotes (JSON needs double quotes inside). Malformed JSON or entries missing string label/href are silently dropped.
• Invalid position/theme/font/items values are silently dropped and defaults apply — check spelling, nothing is logged.
• Button copies nav/sidebar noise → set content to the main selector and/or add exclude selectors. Mark a sensitive element with data-copy2llm-ignore to remove it in every extraction.
• data-header is falsy only for false/0/off/no; any other value keeps the header on.
• The widget lives in a Shadow DOM — page CSS cannot restyle it; use bg/text/font/radius instead.
