This AI chat thread UI for Figma shows a full conversation: a question, an answer with a code block and sources, and a second reply that is still streaming. This is the dark version, made for products that live in dark mode.

What is included

• User bubbles and assistant messages with a gradient AI mark
• A code block with a language label and a Copy button
• Three numbered source cards for citations
• Message actions: copy, like, dislike and regenerate
• A streaming reply with a cursor and a composer with a stop button

Where to use it

Use it for chatbots, copilots, study helpers, developer tools and help centers that answer in a thread.

Design notes

The thread uses a 820 px reading column, which keeps lines short enough to read. Citations sit under the answer, so a reader can check a claim in one click. The streaming state shows a small cursor and a Writing tag. The dark theme uses a #0B0D14 background, #141824 cards, #F3F4F8 text and the same indigo #5B5BF0 accent.

Built for editing

Spacing follows a 4 point scale and layers have clear names, so developers can find what they need. The file uses Plus Jakarta Sans for the interface and JetBrains Mono for code, both free on Google Fonts, and every color is a fill you can change in the fill panel. Text pairs stay above 4.5 to 1 contrast.

How to use it

Copy the component with the copy button and paste it into Figma with Ctrl+V or Cmd+V. The layers keep their auto layout, so you can edit text, colors and spacing. Install the free Google Fonts first so the text looks the same. All names and numbers in the file are sample content.
