jFile NLP - just ask.
Natural-language file management for macOS - describe what you need and jFile finds it.
A multi-pane file manager that understands what you're looking for. Describe the files you need in plain English - or speak your query - and jFile translates your intent into powerful searches across local drives, external volumes, and network shares.
🗣️ Natural Language Search
Combine many search dimensions in a single plain-English query - no syntax to memorize.
How it works: your sentence is turned into search filters entirely on your Mac - nothing about the query leaves the machine. Ask for several things at once and jFile keeps all of them, and it shows you how it read your request before it runs the search.
Search by
- Name - starts with, ends with, contains, exact match, or several patterns OR'd together (wildcards supported)
- File type - broad kinds like documents, images, audio and video, families like Office, iWork, Adobe and CAD, and combinations of them in a single query (“excel and log files”)
- Size & date - ranges and relative terms; by date created, modified, or added
- Content - text inside the file, via Spotlight
- macOS tags & Finder colors, Finder comments, and folder path
Dimensions combine naturally - e.g. “large PDFs named ‘report’ modified last month containing ‘Q4’” runs as one query.
Works everywhere
One search bar for everything you own. jFile searches your startup disk, your external drives, and folders macOS has never indexed - and the same bar reaches straight into your servers: SMB, FTP/FTPS, SFTP, WebDAV, Dropbox and S3, without mounting first from Finder. On a server it matches name, type, size and modified date, and where the server cannot answer part of your query - file contents, tags, comments and owner among them - jFile names that filter on screen for SMB, FTP/FTPS, SFTP, WebDAV and Dropbox searches, so you can see when a result list came back broader than you asked. NFS shares are searched as soon as they are mounted on the Mac.
Example Queries You Can Use
🖼️ Search inside images
Index a folder first via Edit → Index for Graphic OCR Search…. That pass makes the text inside your images searchable straight away; the subject, code and color tags are filled in shortly afterwards, while your Mac is plugged in.
Column Filter Dropdowns
Interactive dropdown filters are a second way to search - use them instead of a typed query, or alongside one. They narrow by Name (extension presets, wildcards), Size, Modified date, Kind (Folder, Document, Image, Audio, Video, Archive, Application), Attributes (hidden, system, read-only), and Finder color tags.
🎤 Voice Search
Dictate your query hands-free with on-device macOS Dictation in English (en-US) - Dictation needs to be switched on in System Settings. Your spoken words fill the search field - then press Search (or Return) to run it. Perfect for when your hands are full or you're working across the room.
🧠 On-Device AI Insights
Select any document and jFile reads it on your Mac to surface a concise summary, automatic tags, and related files - all computed locally, and marked with an On-Device badge in the panel.
How it works: Apple Intelligence, Vision OCR, and the Natural Language framework, all running locally on your Mac.
- Reads almost anything - photos, scans, and image-only PDFs via Vision OCR; Word, Excel, PowerPoint, OpenDocument, Pages, Numbers, Keynote, legacy
.doc, RTF, HTML, and plain text - Transcribe audio & video - right-click → Transcribe to Text for on-device speech-to-text
- Inline Writing Tools - optionally proofread, rewrite, and summarise text right inside jFile's document editor and preview. jFile leaves Writing Tools switched off there until you turn it on in Settings → General, where it explains what may be sent to the cloud before you do. *
- Shortcuts - ask “Find Documents in jFile” through App Intents
* Apple Writing Tools - the one jFile feature that can hand your text to Apple. (macOS itself can also act on selected text through its own menus - Translate and other system text Services - wherever text is selectable. Those are Apple’s, not jFile’s; jFile removes Translate from the context menus of the text it shows you to read or edit - file comments, extracted text, and the document editor and preview.) Writing Tools (proofread, rewrite, summarise) is off by default: you switch it on yourself in Settings → General, where jFile explains exactly what may leave your Mac before you enable it. It works on the text you are editing - the passage you select, or the open document if you select nothing - and never on a file you have not opened in the editor. For longer or more complex requests, Apple Intelligence may process that selected text in Apple’s Private Cloud Compute rather than on your Mac. Apple decides per request whether it needs Private Cloud Compute, and states this data isn’t stored or made accessible to Apple. Leave it off and everything in jFile - natural-language and voice search, OCR, image recognition, and document Insights - runs entirely on-device.
🖼️ See Inside Your Images
jFile reads your pictures. The text written inside them and what they actually show both become searchable, so an image is as findable as a document - computed entirely on your Mac. Nothing is uploaded, nothing is tracked.
- Read the text inside images (OCR) - receipts, screenshots, whiteboard photos, scanned forms, signs, and slides become searchable like any document. Find “invoice”, “boarding pass”, or a phrase you photographed on a slide and the matching images surface instantly.
- Find images by what they show - jFile recognizes what is in a picture - dogs (and breeds), cats, horses, food, plants, vehicles, documents and screenshots - plus people, barcodes and QR codes, and the subject’s dominant color. Just ask: “pictures of dogs”, “photos of food”.
- Colors, categories, and exclusions - stack modifiers and carve out what you don't want: “pictures of black dogs”, “images of animals except dogs”, “images with text”, “images of black dogs except puppies”. Broad categories work too - “images of animals” finds your dog, cat, horse, and bird photos, because jFile understands a golden retriever is a dog is an animal. Everyday plurals just work.
- You choose what gets indexed - a single dialog lets you index the current location (new images, or rebuild the folder), all volumes in one pass (granting access to more drives on the spot), or just selected folders - even straight from a search result.
- Built for big libraries - indexing shows a live count as it scans and can be canceled any time from the status bar. A background pass, on by default, also indexes images in the folders you have granted jFile access to: it runs while your Mac is plugged in, slows down while you are using it, and can be turned off in Settings → General → Image Search.
- Find similar images - right-click any picture to filter that folder down to it plus its closest visual look-alikes, with a live match count - ideal for near-duplicates, resized copies, and icon size variants. It compares the images in that one folder, not its subfolders, and narrows the panel to the reference image plus its nearest look-alikes.
- Extract text from any image - right-click → Extract Text to File… to OCR a single picture into an editable, savable window
👁️ Preview Almost Any File
Click a file and it opens right in the preview panel. jFile renders professional formats macOS cannot preview on its own - CAD and drafting drawings, layered design documents, and EPS and QOI artwork - plus Illustrator files as zoomable vector art, as well as everything the Mac already shows.
Everything is rendered on your Mac. No file is uploaded, nothing needs an internet connection, and a format jFile does not render itself falls back to the system preview rather than a blank pane.
Professional formats jFile renders itself
And there is no format list to consult for the everyday files: if macOS can identify it as text, code, audio or video, jFile previews it - along with the image formats macOS can decode, camera RAW included.
🧰 More Capabilities
Smart Search Engine
- Search is fast on indexed drives and still works where the index is missing or incomplete - jFile falls back on its own and tells you on screen when it does
- Asks before falling back to a full folder scan when the index is present but comes up empty - and where indexing is switched off, it scans directly and tells you so
- Handles very large result sets without slowing the panel down, and the result ceiling is adjustable in Settings
Remote Connections
- FTP and FTPS (TLS), using passive-mode transfers
- SFTP, WebDAV/WebDAVS, SMB
- NFS shares are browsed once they are mounted on the Mac - mount the share in Finder (Go → Connect to Server) and it appears in jFile as a volume
- Amazon S3, Backblaze B2, Cloudflare R2 and Wasabi presets, plus a Custom endpoint for other S3-compatible storage
- Dropbox - you connect with your own Dropbox app key (OAuth with PKCE; no shared client secret is baked into jFile), so the link is between you and Dropbox with no vendor key in the middle. A one-time setup at dropbox.com/developers.
- Copy from a server to your Mac, from your Mac to a server, or directly between two servers - whole folders included
- Saved server profiles with Keychain credential storage
Multi-Pane Browser
- Details, List, and Icons view modes with zoom control
- Live preview panel with metadata - tap the pencil icon to edit file name, dates, and author inline
- Previews CAD, layered-image, EPS and QOI formats in-panel that macOS cannot show natively - and Illustrator files as zoomable vector art - on top of everything it can
- Edit text, Word, OpenDocument, and RTF documents in place - with optional Apple Writing Tools (off by default; enable in Settings → General) - then Save or Save a Copy (your original stays untouched); works on remote files too
- AI Insights tab in the preview - on-device summary, tags, and related files for the selected document
- Favorites, Volumes, Places, and Network Devices sidebar
- Drag & drop between panes and to external apps (Finder, Desktop)
- Open a ZIP or TAR like a folder - and add, remove or rename the files inside it without extracting anything first
- Open any number of detached panels for side-by-side browsing across locations
- Saved Views - save and recall panel configurations instantly
- iCloud Drive integration
File Operations
- Async copy, move, delete, rename
- A copy inside the same APFS volume is made as a clone, so it completes without moving the file’s data
- Every local copy is written to a hidden temporary file and moved into place only once it completes, so an interrupted copy never leaves a partial file at the destination
- Window → Transfers lists every copy, duplicate, move and permanent delete in one window, each row with its own Cancel and a Cancel All
- Context menus matching Finder
- Progress HUDs with cancel support
- Finder Trash integration (Dock + Finder)
- Finder-compatible color tags and tag filtering
- Batch Rename with live preview and conflict detection
- Create new files from built-in templates
- Fast Delete removes a large folder and everything in it permanently - it skips the Trash and cannot be undone, so jFile asks you to confirm first
- Compare two folders side by side, then copy the differences across in either direction
- Folder synchronization between local folders
macOS Integration
- Custom
jfile://URL scheme for scripting - Services menu: open folders or search text from any app
- Drag folders from Finder onto the address bar
- Drag remote files and folders - S3, FTP, SFTP, SMB, WebDAV, Dropbox - to Finder, downloaded on demand
- Dock badge with live copy/move progress
- Network Devices browser - finds the SMB, FTP, SFTP, WebDAV and NFS servers on your local network, including ones that do not advertise themselves
- Native notifications for long operations
- Open Terminal at the current directory from the toolbar
- Brightness/dimming slider to reduce eye strain during long sessions
Volume Health
- Read-only, per-drive diagnostic - explains why search, content previews, or indexing are degraded on a volume
- Reports Spotlight indexing coverage, file identity, readability, and volume facts - each with a confidence level
- Guided and read-only - it copies the exact
fsck_apfs/mdutilcommand for you to run in Terminal, reimports the index, or grants access. Administrator commands stay yours to run
⚡ Fast where it counts
Bulk copying bogs down on the number of files, not the number of megabytes. A folder of thousands of small files is where a file manager either flies or crawls - and jFile copies 5,000 files in about seven tenths of a second, roughly two and a half times faster than the copy tools built into macOS on the same files, the same drives and the same Mac.
It starts instantly, too: jFile does not measure the whole folder tree before the first byte moves, so a big folder begins copying the moment you confirm it.
Measured on macOS 26.6.2, Apple Silicon: 5,000 files of 8 KB each copied between
two APFS SSDs, against the system’s own cp and ditto, seven runs per
tool with the disk cache dropped before every run and the same result warm. One very large file is
limited by the drive rather than the software - jFile is no quicker with those, and we measured
that too rather than guess.

Frequently asked questions
Does jFile require a subscription?
No. jFile NLP is a one-time purchase on the Mac App Store - $4.99 on the US store, with pricing set per country - no subscription, no in-app purchase, no account.
Does jFile send my files or searches to the cloud?
Your files, searches, voice, OCR, image recognition, and document Insights are processed on your Mac - jFile never sends them to us or to any third-party AI service, and we never sell or share your data. Outbound traffic happens only when you ask for it: the servers you choose to connect to, a bug report you write and send yourself, and the optional Apple Writing Tools described below. Text jFile reads for you - OCR text, summaries and tags - is stored in an index on your own Mac so search stays fast. Insights and summaries use Apple Intelligence, on your Mac. One jFile feature can hand text to Apple: the optional Apple Writing Tools, off by default and switched on by you in Settings → General. When you use it, Apple may process the text you are editing in Apple’s Private Cloud Compute; Apple states that data isn’t stored or made accessible to Apple.
What do I need to run jFile?
A Mac with Apple Silicon (M1 or later) running macOS 26 or later. Natural-language search runs entirely on your Mac and does not need Apple Intelligence turned on. Apple Intelligence is used for document Insights and summaries.
How is jFile different from Finder?
Multiple panels instead of one, and a search bar that takes a sentence instead of a stack of filters - ask for files the way you would describe them out loud, “large PDFs from last week”, “spreadsheets I never finished”. jFile searches by name, type, size, date, contents, tags, and even the text inside your images; connects straight to the servers you already use; previews CAD, layered-image, EPS and QOI formats that macOS cannot show on its own; opens ZIP and TAR archives like folders; and renames, compares and syncs in bulk. All of it on your Mac.
What file types can jFile preview?
jFile previews in its own panel the formats you actually work in - raster images, Office, iWork and OpenDocument documents, text and code, audio, video, 3D models, SVG, PDF and Markdown - plus professional formats macOS cannot preview on its own: CAD and drafting files (DWG, DXF, Revit, SolidWorks, Inventor, Rhino, SketchUp), layered-image packages (OpenRaster, Krita, Procreate, Sketch), and EPS and QOI artwork.
Is jFile a full Finder alternative?
Yes - with remote connections (SMB, FTP, FTPS, SFTP, WebDAV, S3-compatible storage, Dropbox), batch rename, and folder sync - and a search bar that takes a plain-English sentence instead of a stack of filters.
