Which vector database should you use for your AI product? A comprehensive comparison of vector databases, based on our research while developing AI Copilots. Explore 11 options, including Turbopuffer, Pinecone, Qdrant, pgvector. lblcks.io/L2bHK65

v3.6.0: See when <AiChat /> is querying your knowledge. When editing your copilot, you can submit websites & documents that your AI can query. Our component now tells you when it's searching through these and what it searched for. Searches support query rewriting & can run multiple times in a row.

entry ≠ exit. A design principle that's rarely mentioned is that entry and exit animations should not be the same. These tabs slide in, yet fade out. Why? Because we're showing intent ↓

I've built an AI web browser! AI chats are way better with context—now you can see exactly where info comes from, trust it, and dig deeper. It'll auto-redirect, open tabs, and fetch pages for you. How it works + code ↓

v3.3.0: New “Show more replies” option in threads. Choose how many replies should be visible before a “show more” button appears. You can also select which messages should show: oldest, newest, or a balance.

First you need to understand embeddings. Embeddings turns words into lists of numbers, a vector, that represent how closely related they are, semantically. Spelling doesn't matter, for example "cat" and "dog" are closely linked, but "cat" and "car" are not.

This July, adding advanced AI to your app got even easier. • Submit whole websites to your AI knowledge base • Polished scroll behavior, improving readability • AI can use custom markdown components Learn more ↓

v3.2.0: Chats in AI Copilots have improved scroll behavior. Messages now animate to the top of the scroll window when sent, making it easier to read AI responses as they stream in.

Mock up AI chat experiences in @figma.com. We've updated our Figma kit, adding new AI components, meaning you can quickly design, prototype, and iterate on conversational UIs.
