# Abacus Docs help center
> Upload documents, extract structured data with schemas, process batches, and ask questions in chat — the Abacus Docs help center.
Abacus Docs turns PDFs and images into searchable text and structured data. Upload a file, apply a schema when you need fields, run a batch when you have hundreds of documents, and ask questions in chat.
Create an account, upload a PDF or image, and open the document viewer.
My Documents accepts PDFs and images up to 64 MB each.
Define the fields you want extracted, then publish and reuse them.
Process up to 1,024 files in one job and export CSV, Excel, or an archive.
Ask questions over documents and attached batches.
Sign in with Auth0, then mint a `sk-abacus-*` key on the API page.
## What you can do
Open [abacusdocs.com/auth/login](https://abacusdocs.com/auth/login). Abacus Docs uses Auth0 — there is no password form on the site itself. New accounts activate **1,000 free credits** (no card required) and accept the terms of service.
Go to **My Documents** and drop a PDF or image. Processing starts when you click **Begin Document Extraction**.
Open the document to see **Sections**, **Transcription**, and an optional **Schema** tab. Use the **Chat** tab to ask questions about that file.
Word, spreadsheet, and HTML uploads are [not generally available yet](/digital-documents). Black Hole ingest is available to [selected organizations](/black-hole) only.
