Getting Started with Keyline
The fastest way to understand Keyline is to upload a document and ask it a question. This page walks through that first upload, what happens behind the scenes, and where to start reading once it is done.
Upload your first PDF
Open your library and choose the upload option, then pick a PDF from your computer. There is a maximum file size and page count (see the FAQ for the current limits). Once the file starts uploading, you will see a progress indicator while Keyline processes it.
What happens after you upload
Uploading a file does two things at once:
- Analysis. Keyline reads the document with Google Gemini's multimodal understanding, which includes recognizing figures, diagrams, and tables in addition to plain text.
- Indexing. Keyline builds a search index for the file so it can be found later, both on its own and as part of a multi-file search across your whole library.
Both steps run automatically. You do not need to do anything else once the upload starts; Keyline shows progress and the document becomes readable as soon as processing finishes.
Where to start reading
Once a document finishes processing, open it to reach the PDF view, where you can page through the document and start a conversation about it. See Reading and analyzing PDFs for how the page view works, or jump straight to Conversations and citations to start asking questions.
