Compound has a few ways to get data in front of the agent. The simplest is to upload files directly into a Drive (drag onto the Files tab or the chat composer) — see Drives and files for supported types and how it works. This page covers the other two paths: built-in public data sources you toggle on per chat, and the Google Drive connector for pulling files in without re-uploading. All of them feed the agent the same way — as context it can read while answering.
Public data sources
Public sources live in the chat composer under Public data. Toggles are remembered per chat, so a chat scoped to a single company can keep the relevant sources on without re-enabling them each message.
- SEC Filings — 10-K, 10-Q, 8-K, proxy statements, S-1, 13F, and other forms pulled live from EDGAR. Reference filings by ticker and form type in your message and the agent retrieves them.
- Web — live web search. Best for current news, market events, or anything that wouldn’t be in a filing.
- Earnings Transcripts — earnings call transcripts. The agent can quote speakers with citations.
- Polymarket — prediction market data. Use for event probabilities the market is pricing.
- Stocks — price and fundamentals (P/E, market cap, dividends, technicals).
You can combine sources freely. “Compare what Acme said about gross margin on the Q3 call to the latest 10-Q and to consensus estimates from the web” would draw from Earnings Transcripts, SEC Filings, and Web.
Google Drive
Connect Google Drive once and Compound can browse and import files from it without you having to download and re-upload.
Connect Google Drive
Open the file picker in any chat or Drive and choose Add from Google Drive. You’ll be redirected to Google’s OAuth flow to grant Compound read access. Once connected, you can browse your Google Drive files directly from the picker.
Import a file
In the picker, navigate to the file you want and click to add it. Compound copies the file into your Drive (it doesn’t sync continuously — this is a one-time import). It’s available as context in the chat right away.
To bring in an updated version later, import again — a new version is created in the Drive.
The connection is scoped to your user account, not per Drive. Files already imported into a shared Drive stay accessible to everyone they were shared with, regardless of your connection state.
Which option to use
A few guidelines:
- For internal documents, drafts, or anything non-public: upload directly. It’s the fastest path and works with any file on your machine.
- For SEC filings of public companies: use the SEC Filings toggle. You’ll always get the canonical version and accurate page citations without having to download anything.
- For files already in Google Drive: use the Google Drive connector instead of downloading and re-uploading.
- For repeated work on the same source: put it in a Project Drive once — everyone with access to that Drive can use it from then on.
