OmniText

Omnitext is a private, offline editor that adapts to whatever file you open. One app for code, data, documents, PDFs and spreadsheets, all on your device.

Everything runs locally. Your files are never uploaded. There is no account, no sign-in, no tracking and no ads. Open a file, edit it, and save it back, completely offline.

WHAT YOU CAN EDIT
- PDF: edit text in place, add text and images, zoom and pan.
- Word (.docx) and OpenDocument (.odt): rich text, headings, tables, page layout, comments and tracked changes, preserving the parts you do not touch.
- Spreadsheets (.xlsx, .ods): a grid editor with multiple sheets and formulas.
- Code and data: JSON, JSON5, YAML, XML, HTML, CSS, Markdown, CSV/TSV, INI, TOML, SQL, LaTeX, shell, JavaScript, TypeScript, Python and more, with syntax highlighting.
- Markdown in a clean rich-text view, or as raw source.
- View images, audio, video and archives.

BUILT FOR PRIVACY
- 100% on-device. Nothing leaves your phone.
- No account, no analytics, no ads.
- Open source.

HANDY FEATURES
- The right editor for each file, chosen automatically.
- Version history so you can roll back changes.
- Round-trip safe: untouched parts of your documents are preserved exactly.
- Works offline, every time.

Omnitext is ideal for quickly opening, reading and editing almost any text-based or office file on your phone, without handing your data to anyone.
