Everything you keep, in one place at last

One window: your folders on the left, your documents in the middle, the preview and details on the right.

Find it, even inside a photo

Folium reads the text of everything you give it, including scanned documents and photos, thanks to text recognition.

  • PDFs, Office documents, emails, web pages, ebooks
  • Search that ignores accents and capitals
  • The preview opens right on the word found

Your photos, full size

Browse thousands of photos as thumbnails, open them full frame and find everything the camera recorded.

  • Camera, lens, settings and place of every shot
  • Edit with sliders or in one click, the original always kept
  • RAW files and panoramas displayed

Photo adjustments: tones, colour, detail

Read, annotate, listen

Ebooks and PDFs open in the Folium reader, on one page or two.

  • Bookmark and coloured sticky notes
  • Read aloud, offline
  • Search the whole book

Leaf through your folders

Presentation mode shows each folder or document full size, with a filmstrip to move from one to the next.

  • Cover or first page as a thumbnail
  • Star rating in one click
  • Folder details on the right

Folders that fill themselves

Write a rule once. Matching documents file themselves, on import and when an email arrives.

  • Keywords, file type, dates, tags, sender
  • Due dates with a warning before it is too late
  • Your Windows folders imported as they are, originals untouched

Ask your documents

Ask a question in plain language. Folium finds the relevant passages and submits them to the AI you chose, which answers and cites its sources.

  • Summary and translation of a document
  • A filter first masks account numbers and identifiers
  • Nothing leaves unless you ask

Photos

A full-frame viewer with its filmstrip, stars to sort, and every shooting detail: camera, lens, settings, place. RAW files are displayed too.

Photo adjustments

Colour temperature, sharpness and noise are corrected with a few sliders, or in one click on automatic. The original is never changed: the edit becomes a new version.

Timeline view

Your documents sort themselves by decade, year and month, from their real date: when a photo was taken, an email sent, a book published.

Mind maps

Draw your ideas and link each branch to your documents. Folium also draws the map of your library and flags upcoming due dates.

Email filtering

Each mail account has its rules: by sender, subject or content, a message is filed, tagged, rated or set aside. Junk mail is never fetched.

Web pages and RSS feeds

A web page is saved as a self-contained document, readable offline. Your RSS feeds arrive as articles, ready to be filed.

Scanning

The document in your scanner is captured and recognised. Folium suggests where to file it and spots dates, amounts and sender.

Reader and read-aloud

Ebooks and PDFs are read page by page, with a bookmark and notes. A voice reads the text aloud, with no connection.

Tags and ratings

Each document can carry tags, a colour and a rating. A folder passes its tags on to what it contains.

Online drives

Send or fetch folders on your Nextcloud, kDrive, Koofr or HiDrive space. Folium never deletes anything there.

Sharing between your computers

Share a folder with another computer or with a contact, read-only or read-write, and withdraw it whenever you decide.

Free to leave

Export everything, at any time, as ordinary folders readable without Folium. Your documents are never locked in.

Privacy

Your documents stay yours

Folium is an application installed on your computer, not an online service.

Local storage

Your documents and their index are on your disk, or on your own file server.

End-to-end encrypted sharing

The relay that connects your computers carries data it cannot read.

Protected folders

Their content is encrypted with AES-256. The password is stored nowhere.

AI under your control

Nothing is sent to an AI unless you ask, and sensitive data is masked before it leaves.

Voice and recognition on your machine

Voice, text recognition and search all run on your computer.

No ads, no trackers

Folium does not watch you. Neither does this site: no cookies, no audience measurement.

Pricing

One price, paid once

No subscription. The software you buy keeps working with no time limit.
