Everything Office, on your desktop

    Tracked changes, comments and a save that rewrites only what you edited.

    Pivot tables, charts and formula tracing on native .xlsx files.

    Decks that open cleanly everywhere

    Masters, layouts, smart guides and non-destructive crop for .pptx.

    Edit the real text in a PDF

    Change text and images in place while keeping the original fonts.

    Plain Markdown, friendly editor

    Tables, code blocks and export to Word — still a plain .md file.

    PDF to Word, Excel and PowerPoint

    Convert on your computer — nothing uploaded — with OCR for scanned pages.

TinyOffice AI Assistant mascot

An AI assistant that works inside your files

It edits, searches and creates with you — and asks before it changes anything.

  • Web search
  • Image generation
  • Image & audio analysis
  • Transcription
  • In your document

    Edits you review first

    Rewrite a section, fill a sheet or build slides. Every change arrives as a diff you approve.

  • Across a project

    Works across a whole folder

    Searches, reads, creates and reorganises files in a project — with your approval.

  • From the home screen

    Ask your notes and books

    Answers from your notes, book highlights and task boards, then creates notes and cards.
