About Summarize

Get a short, structured brief of a PDF or text file: what it is, the key facts, decisions, numbers, and open questions. The summary is written by an AI model.

How to use Summarize

  1. Drop a PDF or .txt file onto the sheet.
  2. Press Run; Inkwell extracts the text and asks an AI model for a brief.
  3. Read the summary on screen or download it as a .txt file and a PDF.

Frequently asked questions

Is my document sent anywhere?
Yes, the text is. Inkwell extracts the text in your browser, then sends it through its server to DeepSeek, a third-party AI provider, which writes the result. The file itself is not uploaded, but its words are, so do not use this tool for text you cannot share with a third party.
How long a document can it summarize?
Only the first 14,000 characters of text, roughly 2,000 words, are read; anything after that is cut off. For longer documents, split them and summarize each part.
Why does it say the file has no extractable text?
Scanned PDFs are pictures of text. Run OCR PDF first, then summarize the text file it produces.
