Typography

Each font links to its Google Fonts page where available.

Not found on Google Fonts? Agent Instructions that you can follow if you have permission to use the fonts:

CharacterQuilt.com suggests this flow that can help:

1. Open the company's homepage in a browser with DevTools open.
2. In the Network tab, filter by "Font" (or by extension: woff2, woff, ttf, otf).
3. Hard-reload the page and click around (pricing, blog, careers) — some weights only load on specific routes.
4. For each captured font URL: right-click → Save As to download the file locally.
5. View the page's CSS (DevTools → Sources, or curl the stylesheet URLs) and copy out the matching @font-face declarations. Rewrite each `src: url(...)` to point to your local file path.

Programmatic alternative: load the URL with Playwright or Puppeteer, listen for `response` events whose `Content-Type` starts with `font/`, and write the body to disk. The CSS extraction step is the same.

Only do this if you have permission to use the brand assets — most proprietary fonts are licensed and may not be redistributable.

Frequently Asked Questions

Methodology

Brand data on this page was extracted from https://www.letta.com/ using the Firecrawl branding extraction API, which extracts website design information. An extraction date was not recorded for this profile. The source site may have changed since the snapshot was captured, and a redirect may lead to a different company or product. Brand-in-the-wild images were found using image search. Cached previews link to original third-party sources. This page is published by CharacterQuilt and is not affiliated with or endorsed by Letta.
