Web Scraping Engine

Just paste a URL. We use Puppeteer + LangChain to scrape, clean, and vectorize entire documentation sites in seconds.

Mobile Native

Responsive chat interface that feels native on iOS & Android.

Summarize this PDF for me.
Based on the document, the key points are...

Multi-File PDF

Drag & drop multiple PDFs. We handle the chunking logic automatically.

Smart Vectors

-33% Cost

Forced 1024-dim optimization reduces Pinecone storage bills.

Developer First

Code you actually want
to maintain.

No black boxes. No hidden abstractions. You get full access to the `pages/api` routes. Customize the scraper, swap the vector DB, or tweak the prompts in minutes.

Headless Browser (Puppeteer)

Renders React, Next.js, and SPA sites perfectly via Browserless.io.

Namespace Isolation

Prevents context bleeding by creating unique vector buckets per user.

Streaming Responses

Vercel AI SDK integration for real-time typing.
