InLet
Private
Your files never leave your Mac
InLet reads your files locally and keeps everything on-device. Nothing is uploaded, no API key required.
Free for Mac
Finally, a Downloads folder you can search.
It just works.
InLet runs quietly on your Mac, watches your Downloads folder, and gives every file a name you'll actually recognize later. It can also rename everything inside an entire folder in one pass. Your files never leave your Mac — no account, no subscription, nothing to set up.
v0.1.1 · Standard 2B + High Fidelity 4B · Apple Silicon Mac · macOS 14 or newer
No cloud. No account. Nothing to configure.
InLet is a small Mac utility. It lives in your menu bar, stays quiet until a file arrives, and does its job without getting in the way.
Quiet
Runs in the background
It sits in your menu bar and handles incoming files as they arrive. No window to keep open, no interruption to your work.
Safe
Every rename is undoable
Not happy with a suggestion? You can reverse any rename with one click, right from the menu bar.
From a useless filename to one you can actually find.
InLet handles the worst part of downloading: files that arrive with names like document (3).pdf or IMG_1204.PNG that you'll never find again. It works on individual files as they land, or on entire folders at once.
01
Download InLet and add it to your Mac
Open the file you download, drag InLet into your Applications folder, and launch it. That's the whole install.
02
It watches your Downloads folder automatically
The moment a file finishes downloading, InLet reads it locally and figures out what it actually is.
03
You see a clear name — approve, adjust, or skip
InLet suggests a better name and adds searchable tags. Accept it, change it, or ignore it. You're in control.
04
Or point it at a whole folder
Have an existing folder full of badly named files? InLet can rename everything inside in one pass, with the same review flow.
Two editions, both free.
InLet comes in two local-first builds. Standard keeps the bundled model lighter. High Fidelity bundles the heavier Qwen 3.5 4B model for better rename quality, but it asks more from your Mac.
Standard
InLet
Bundles Qwen 3.5 2B locally. This is the lighter default build and the safest choice for most Apple Silicon Macs.
- Watches Downloads and any extra folders
- Renames entire folders in one pass
- Finder tags and searchable comments
- One-click undo from the menu bar
- Smaller download and quicker local processing than High Fidelity
High Fidelity
InLet High Fidelity
Bundles Qwen 3.5 4B with the MLX runtime. It installs with no setup and aims for better rename quality, especially on harder documents.
- Everything in Standard
- Bundled Qwen 3.5 4B model — no API key needed
- Works right away with no extra configuration
- Better rename quality on complex documents
- Heavier download, slower processing, and more memory use than Standard
Download InLet and start with Downloads.
Both editions work on Apple Silicon Macs running macOS 14 or newer. Standard is lighter. High Fidelity uses the 4B local model and performs best on newer Apple Silicon Macs.
