Features
Everything Docsi does for you.
Docsi AI is a desktop app that reads documents, calculates and delivers finished files: from lecture notes to study sheet, from table to report, from photo to text.
How Docsi AI works
- 01
Drop it in
Files, whole windows from your browser or notes, copied text – or simply a question.
- 02
Say what you need
“Make me a study sheet”, “Analyse this table”, “Sum it up on one page”.
- 03
Done
Docsi hands back a clean file – as PDF, Word, Excel or Markdown, with sources and page numbers.
Results
Looks like hard work. Wasn’t.
Study sheets, reports, analyses, flashcards: Docsi lays out key figures, tables and charts so you can hand them in, print them or send them on right away.

Private
Your files stay on your computer.
Processed locally
Converting, merging and text recognition run on your device, without the internet.

For AI tasks, only the text that is needed travels encrypted through our server to the AI provider. None of it is stored.
No account
A license key instead of a login. Payment runs securely through Stripe; we never see your payment details.
Questions
Questions about the features
Do Word and Excel files stay editable?
Yes. Word files are real DOCX documents with headings, lists, tables and page numbers; the Inter typeface is embedded. Excel workbooks contain real sheets and native charts that you can keep adjusting in Excel.
How exact are calculations on tables?
Docsi calculates count, sum, average, median, minimum and maximum exactly from the cells of your file, not as an AI estimate. Decimal commas (“12,4”) and grouped numbers (“1,234.56”) are recognised. Formulas without a stored result are not counted as numbers.
Can Docsi read handwriting?
No, not reliably. Local text recognition is made for printed text in German and English. The recognition confidence shown is an estimate, so always check amounts, names and dates against the original.
Can I use an AI of my own?
Yes. In the settings you can optionally connect your own AI with your own key, or a local model through Ollama or LM Studio. The subscription is still required; local tools work with any setting.
