# Supported Data Types

Echo extracts structured data from your emails and PDF attachments. Anything written in plain text can be picked up — if it's in the email body or an attached PDF, Echo can read it.

## What Echo extracts

Echo pulls out the types of data that naturally appear in emails: things like amounts, dates, names, and statuses. More specifically, Echo works with data that maps to standard schema.org types — a widely used vocabulary for describing real-world information.

In practice, this means Echo can extract:

* Amounts & prices — invoice totals, subscription fees, refund amounts
* Dates & deadlines — due dates, expiry dates, flight times, tax deadlines
* Names & organizations — vendors, senders, airlines, tax authorities
* Reference numbers — invoice numbers, booking codes, PNR, tracking IDs
* Statuses — paid, overdue, confirmed, delayed, cancelled
* Promo codes & offers — discount codes, expiry, savings value
* Addresses — billing addresses, delivery addresses
* URLs & links — payment links, tracking pages
* and more

If a value appears as readable text in an email, there's a good chance Echo can extract it.

## PDF attachments

Echo reads text from PDF attachments automatically, no setup needed. This includes invoices, receipts, boarding passes, and tax notices sent as attached files.

> Images and scanned documents are not supported. Echo can only extract text it can read directly, not content embedded in photos or non-searchable PDFs.

## What Echo doesn't extract

* **Images** — logos, photos, banners, and image-based content are ignored
* **Scanned PDFs** — if the PDF is a photo of a document (non-searchable), Echo can't read it
* **Data outside the email** — Echo only reads what's in the email body and its attachments, nothing else

## A note on accuracy

Echo uses AI to interpret context, not just copy text. This means it can infer a status ("this invoice is overdue") or normalize a format ("€1.200,00" → "\$1,200.00") — but it can also make mistakes. Always verify critical data against the original email.
