Files

The PDF somebody sent you, the scan you cannot copy a word from, the form that has to go back signed. Sentiora Files opens, edits, redacts, signs, converts and reads documents on your own computer, with no account and no upload. The assistant is the one part that can reach the internet — and only after you give it a key of your own.

Version 1.5.6 / 15 workspaces / 14 languages / Windows

The Sentiora Files Reader in the dark theme, showing page one of a two-page service agreement between Brightlake Consulting and Alder & Finch Design, with page navigation, fit width, fit page, thumbnails, view and annotate buttons, a search box and Save annotated. — **Reader, dark theme**A two-page service agreement, read on the page as it prints.

/ The tour

A week of paperwork, done on your own machine.

Screens from Sentiora Files 1.5.6, worked through with sample documents — a service agreement, an invoice, a scanned letter — between two firms that do not exist. Every figure on them is the application’s own, and the assistant is running offline, with no key.

01 / Reader

Read it comfortably, then write on the page.

Pages run on one after another; Fit width, Fit page and Thumbnails set the view, and the page box jumps straight to one. Search counts every match in the document, with or without capitals. In Annotate you pick text, pen or highlighter in any colour — saved to a new copy, so the contract you opened is never changed.

02 / Writer

A letter written here goes out as PDF or Word.

Bold, italic, underline, strike-through, subscript and superscript, text and highlight colours, alignment, lists, indentation and line spacing. Find and Replace work across the whole document, with the words and characters counted underneath. It opens TXT, HTML and DOCX and saves PDF, Word, HTML or TXT.

03 / PDF Tools

Rearrange a PDF by dragging its pages.

Every page is a thumbnail: drag it into place, rotate it 90° or 180°, remove it with Del, and Undo or Redo any step. Nothing is written until you press Save changes, and Reset edits brings the file back as it was. For the whole document: split into pages, compress, lock with an AES-256 password or take one off.

04 / Redact

Names and amounts removed for good, not covered over.

Type what has to go, one line each, and Find matches says where it is before anything changes — here four matches on two pages, and four document properties carrying the same names. Redact and save writes a new copy: matched pages become images with the words blacked out, and the notes, form fields, bookmarks and properties holding them are cleaned too.

05 / OCR

A scanned letter becomes text you can copy.

Open a scanned PDF or a photo, pick the languages in it — English and Romanian here — and press Run OCR. The text appears underneath; save it, or make a searchable PDF that still looks exactly like the scan. Twelve languages are included; the free Tesseract engine is installed once, and the application shows where to get it if it is missing.

06 / Convert

Into PDF and back out, with nothing extra installed.

Drop the files in, choose the format, press Convert. On any Windows PC: Word, text, Markdown, HTML and photos — JPEG, PNG, WebP, TIFF, BMP, GIF, HEIC — into PDF, and a PDF back out as Word or images. EPUB, RTF and conversions between text formats appear only with LibreOffice or Pandoc installed, and the screen names what it cannot offer on this computer, and why.

07 / Inspect PDF

What is inside a PDF, before you send it.

Size, pages, PDF version, encryption, whether it is optimised for the web, the first page’s dimensions, title, author, subject, keywords, the program that made it and its dates. Edit metadata changes the properties you would rather not share; Copy and Save report take the whole list with you.

08 / Fill Form

A form filled in without a printer.

Text boxes, tick boxes and drop-downs come up as a clean list. Fill them in, tick Lock fields if nobody should change them afterwards, and Save filled PDF writes a completed copy — diacritics included, password-protected forms too. It works on forms with real fields; a flat scan has none, and that one you write on in Reader.

09 / Merge Studio

Several documents, one file.

Add PDFs and photos; every page arrives as a thumbnail labelled with the file it came from. Drag them into order, rotate or remove what you do not want, choose the folder and the name, and Start merge writes one document in exactly that order.

10 / Sign PDF

A signature on the page, typed, drawn or from a picture.

Your name typed, drawn with the mouse, or a picture of your signature; then the page, a corner or the middle, small, medium or large, and today’s date if you want it. Sign and save writes a signed copy. It is a visible signature, not a certified digital one.

11 / AI Assistant

The gist of a long document, with no key at all.

Load a file or paste the text: Summarize, Suggest title and Classify work offline with the engine built in — here it names a service agreement and calls it a contract. Offline summaries are simple. Connect Claude, ChatGPT, Gemini, Mistral, Groq, DeepSeek or a local model in Settings for sharper ones, and the document’s text then goes to that provider — the page says so at the top.

12 / Smart PDF

Loose files and pasted notes, one tidy PDF.

Add documents, photos or text, pick a template — Modern, Classic, Minimal, Business, Photo album or Letter — and Create PDF lays out a title page, styled sections and the photos for you. The preview on the right shows the template before anything is written.

13 / Batch

Every PDF in a folder, in one go.

Choose the folder of PDFs and a folder for the results, then what to do — compress at quick, balanced or maximum, add a watermark, or number the pages — and Run on all PDFs. The originals are never modified; everything lands in the folder you chose.

14 / Home

Start where you left off.

Open a PDF, begin a new document, jump to the tools used most, or pick up one of the last files. A cross takes a file off the list without touching the file itself, and Report a problem opens your own email with the message already written.

15 / Settings

A licence screen that says what goes online.

Light or dark, five app icons, English and thirteen more languages. Your own AI key, stored encrypted on the computer. Under Licence you paste the key you were sent — hidden behind dots until you press Show, with no address to type; an email line appears only for the older keys that carry one. The text says it plainly: once a day, a scrambled form of the key and of the computer, and the version number — never your email, your name or your documents.

/ Capabilities

For the questions the tour does not answer.

Every workspace, with the details that decide a purchase: what stays free after the trial, which conversions need LibreOffice, and exactly when a document’s text leaves the computer.

01READOpen, search and annotateFree after the trial

Continuous scroll with thumbnails, jump to page, and an outline built from the document's own bookmarks. Pages are drawn as you reach them, so a thousand-page file opens at once and does not fill the memory
Zoom with the buttons or Ctrl+wheel, fit-to-width and whole-page. On a 4K screen the text is drawn at the screen's resolution, not enlarged from a small picture
Select text with the mouse and copy it (Ctrl+C); double-click takes a word; links in the document work, to another page or out to the web
The reader does not rotate and has no two-page mode — rotation is in Page work, below
Search the whole document with or without capitals, and a count of the matches
Annotate with text, pen and highlighter, in any colour
What you draw saves to a new PDF — the file you opened is never modified. Reading stays free after the trial; saving the marked-up copy needs a licence
Password-protected PDFs open throughout, once you have typed the password

02WRITEA word processor that exports PDF

Bold, italic, underline, strike-through, subscript and superscript, text and highlight colours, alignment, lists, indentation and line spacing
Find and replace, including replace-all, with a live count of words and characters
Opens TXT, HTML and DOCX; saves PDF, DOCX, HTML and TXT
Undo and redo cover every step, not only the last one

03PAGE WORKThe page grid is a working copy

Reorder by dragging, rotate 90 or 180, delete, extract into a new PDF
Split into separate files, lock with an AES-256 password or take one off
Compress on three steps — quick, lossless, structure only; balanced, pictures and scans down to 150 DPI; maximum, 100 DPI with scanned text at one bit. It then says how much came off and how many images it re-coded: on a 1.4 MB scan, maximum took off 68%
Nothing is written until you save, and one button brings the file back as it was
Several files chosen at once go straight to Merge Studio

04INSPECTWhat a file really isReads only

Size, page count, PDF version, encryption, whether it is optimised for the web, the first page's dimensions
Title, author, subject, keywords, producer and dates — and you can correct the first four
The report copies or saves, which is what you send when a PDF is refused somewhere and nobody says why

05MERGEAny number of files, one order

Add PDFs and images, drag them into order, drop the pages you do not need
Rotate what came in crooked before it is merged, not after
Undo and redo across the whole assembly

06REDACTRemoved, not covered

Type the names, numbers or addresses to remove, one per line, and they leave the file
Not a black rectangle over text somebody can select underneath — matched pages become images with the words blacked out, so there is nothing left to select
The word is taken out of every place a PDF keeps it: notes and comments, form field values, bookmarks, properties and metadata. Attachments are left out — and said to be left out — because they cannot be searched
Find matches tells you everything it is about to do, before it does it
A scanned page has no text to find, and Sentiora Files warns you instead of passing it off as clean
The redacted copy is not encrypted, and the application says so before it saves

07SIGN & FORMSSignature and fillable fields

Sign by typing your name, drawing with the mouse, or bringing a picture; choose the page, a corner or the middle, three sizes, and today's date if you tick it
Open a PDF with form fields, fill it in, save it
One tick locks the fields, radio-button groups included, so nobody changes them after you
Letters with diacritics survive: ăâîșț stay ăâîșț, drawn with the application's own font, in any reader
A password-protected form asks for the password and says plainly that the filled copy will no longer be protected

08CONVERTFormats in and out — and it says which work here

With nothing else installed, into PDF: Word (docx), text, Markdown, HTML, and photos — JPEG, PNG, WebP, TIFF, BMP, GIF, HEIC. Photos of any kind go together into one PDF; documents convert one type per batch
With nothing else installed, out of PDF: Word (docx), JPEG, PNG, TIFF and WebP
With LibreOffice or Pandoc installed, more appears — EPUB, RTF and conversions between text formats
The menu shows only what works on your computer, and says in one line what it does not offer and why — it does not offer a format and then fail on it
A PDF back into Word keeps the headings, type sizes, tables, pictures and columns in reading order, and leaves the repeated header and footer out

09OCRText out of scans and photographs

Twelve languages included — English, Romanian, French, German, Spanish, Italian, Portuguese, Dutch, Polish, Hungarian, Turkish, Russian — several at once for mixed documents, with diacritics
Take the text as it is, or make a searchable PDF: the scan stays exactly as it looks and the text underneath can be selected and found
Fast mode for a quicker, rougher read
The OCR engine is installed once, separately — Tesseract, which is free. If it is missing, the application shows where to get it

10BATCHThe same operation over a folder

Compression at quick, balanced or maximum, a watermark, or page numbers, across every PDF in a folder
The originals are never modified; results go to the folder you choose
Progress names the current file; stopping halfway does not spoil what already finished
A log you can save, saying which file failed and why — not a count of failures

11ASSISTANTStarts offline. Reaches further only if you say so.Uses your key, and the internet

A summary — short, detailed, in points or by chapter — a suggested title, what kind of document it is, and questions about what you loaded, with the conversation kept
It works on first launch with no key, no account and no internet, with the engine built in. The offline summary is simple; good summaries need a model connected
For stronger answers you connect your own key: Claude, ChatGPT, Gemini, Mistral, Groq, DeepSeek — or a model running on your own machine through LM Studio or Ollama
The key is encrypted on your computer and travels to the one provider you picked. An indicator always shows who is answering
The document reaches the model whole, page by page: a long one is summarised in parts, and a question is answered from the pages that share the most words with it
The answer names the page — (p. 4) — and underneath says what the model actually saw: the document has 200 pages; the model saw pages 1, 2, 4, 6. Nothing is cut in silence
Those tokens are billed to you by the provider, not by us. Answers copy, save to a file, or clear together with the conversation

12SMART PDFText and pictures in, a laid-out document out

Six templates — Modern, Classic, Minimal, Business, Photo album, Letter — with a preview before anything is written
PDFs, text, Word, HTML, photos or pasted notes, turned into one document with a title page and styled sections
Pictures are placed, not pasted at the end

13EVERY PAGEWhat holds across the whole application

Languages — 14 — English, Romanian, Spanish, French, German, Portuguese, Italian, Russian, Chinese, Hindi, Bengali, Japanese, Korean, Arabic
Themes — Light and dark, switched in place with Ctrl+T
Icons — 5 to choose from in Settings — the desktop shortcut changes with it
Problem report — Collects the version, the Windows build and the log by itself, and opens your email with the message already written
Drag and drop — On every page, into the place where it makes sense
One window — A second file opened from Explorer goes into the window already running
No freezing — Every long operation runs on its own thread; the window keeps answering

/ Limits

What it does not do.

Written here rather than discovered after you have paid.

01YOUR FILESDocuments do not leave your computer

Not to us, not to anyone else
With a licence active, once a day the program reports that this copy is in use: a scrambled form of the key and of the computer, and the version number — never your email, your name or your documents
The exception is the assistant, and only when you have connected a model. Then the text you ask about goes to the provider you chose — that is what a key is for, and it is off until you turn it on

02EDITING PDF TEXTIt does not rewrite a paragraph in place

Rotate, delete, extract, merge, redact and annotate — yes
Click into an existing sentence and retype it, the way a professional PDF editor does — no

03SIGNATURESNot a certified digital signature

The signature is a visible one, placed on the page
It is not the legally recognised kind backed by a certificate

04PERMISSION TO RUNIt never asks anyone whether it may start

The licence is checked on your machine, against a key built into the program
With no internet it starts exactly as fast

/ Release

Reading stays free, always.

The trial runs for fourteen days, with everything open, and asks for no card and no account. When it ends, opening, viewing, searching and inspecting keep working — saving, exporting and the rest need a licence, which costs $39 once — $69 for all three Sentiora tools. Nobody is locked out of documents they have already made.

You are sent a key and nothing else — no address to type, no account to make. It is checked on your own computer against an Ed25519 signature built into the program, so it works with the network cable out. Once a day, with a licence active, Sentiora Files reads the list of stopped licences and reports that this copy is in use; the rule the whole thing is built on is that a licence can only be taken away, never given — no answer, no internet, and the program carries on exactly as before.
