SmartDecrypt · iOS / macOS / Win

Comic Duplicate Scanner.

Find and remove duplicate comic archives, photos, and files — even when they've been renamed, recompressed, or saved in different folders. Visual matching, not filename matching.

01CBZ, CBR, ZIP, RAR. Opens each archive and compares the actual pages inside using perceptual hashing.
02Photo deduplication. JPG, PNG, HEIC, WEBP, BMP, GIF. Catches recompressed and rescaled copies that file-size tools miss.
03Safe by design. Marked files go to system Trash, never permanent delete. Last-copy safety warning before any batch operation.
04Hash cache. Repeat scans of the same folder are near-instant. Local SQLite, never uploaded.

GrepTag.

Searches the full text of your local TXT and EPUB files and tags your library from what is actually written inside — no metadata entry, no ISBN lookup, no cloud index.

01Grep scan, free and unlimited. Type a keyword and see exactly which files contain it, matched against the full text.
02Saved keyword profiles. AND, OR and NOT logic in named profiles that re-run automatically as new files are imported.
03Covers for plain TXT files. Matched from a same-named image in the folder, or fetched from a URL you paste.
04Your tags stay yours. Exportable JSON tag database; Wi-Fi sync over your own network, never our servers.

ContentCue.

A mobile browser built for content readers. No tracking, no history stored — and a one-tap position restore so you never lose your place when popups interrupt.

01Position restore. Auto-saves your scroll position before any interruption. One tap gets you straight back to where you were reading.
02Visual ad distinction. Colored borders around in-page ads so you always know what's content and what isn't.
03Audio mute toggle. Silence autoplay audio site-wide with one tap — read in peace in public or quiet spaces.
04Zero tracking. No browsing history stored, no analytics, no data collection. Everything stays on your device.

§ 05 — Earlier work

Also in the store.
Older utilities, still maintained.

A handful of earlier Windows-only utilities from before the studio's recent native-first push. Offline, focused, still listed.

A / 01 Py2MSIX Turn Python scripts and folders into signed MSIX packages for the Microsoft Store — no command line. MS Store ↗ A / 02 Image Tagger Pro Batch-write titles and keywords across thousands of JPEGs. For stock photographers and dataset curators. MS Store ↗ A / 03 SourceSeeker AI Find original high-res photos using local visual search. Analyses the image itself, not the filename. MS Store ↗

§ 06 — Product philosophy

Every product in the studio is built to work for you, not to study you. Privacy is not a feature — it's the default that everything else is shaped around.

01 · On-device

Processing happens locally whenever it can. Your files, your client list, your library — they stay on your hardware.

02 · No tracking

No analytics SDKs, no behavioural pings. If a product needs a server, it does the minimum and nothing more.

03 · Built to last

Native frameworks, modern stacks, careful dependencies. Software that should still feel good in five years.
