Short answer
Pick Renamer.ai if you want a web tool plus a Windows and Mac desktop app with templates and Magic Folders. Pick Filewise if you want reading and naming to stay on the Mac, with a plan to approve and no plan to buy.
What is Renamer.ai
Renamer.ai is the AI file renamer at the top of Google for "ai file renamer mac". It renames PDFs, photos and documents: drop files in the browser and it reads and renames them, or use the desktop app (version 5.0.3 at the time of checking). It offers bulk renaming with renaming templates and Magic Folders that organize files in the background, and claims 6,100+ happy users (a vendor claim). Its privacy statement separates the web version from the desktop app.
Side by side
| Dimension | Filewise | Renamer.ai |
|---|---|---|
| How it works | Reads file contents (PDF text layer, OCR on scans) and a local AI proposes names and destinations | Drop files to rename them; bulk rename with a renaming template; Magic Folders organize files in the background |
| Platform | Apple silicon only, macOS 14 or later; a DMG from the website, or install with Homebrew | Web app, plus a desktop app for Windows and Mac |
| Price | Free to download for now | Free start with no card; paid monthly plans are listed at $9.95, $29.95 and $99.95 per month but the page did not make the plan mapping clear (unverified) |
| Do contents leave your Mac? | No. Reading and naming run on the Mac | Web version: files are stored temporarily for up to 24 hours so you can download them. Desktop app: the site says files are not stored after processing and are renamed on your device; where the AI model runs is not spelled out (unverified) |
| Confirm before renaming | Shows an "original name → new name" plan first and acts only after you approve | Not described in detail on the pages we read (unverified) |
| Undo and deletion | Every step goes into an undo log that survives a restart; it only renames and moves, never deletes | Not described on the pages we read (unverified) |
"Unverified" means we did not see a clear statement on the official pages, not that the feature does not exist. Prices, features and user counts are vendor claims and change; check the vendor's own site before you buy or download. Checked 2026-10-16.
How this page was checked
The facts about Renamer.ai come from its official pages (sources at the bottom), read in a real browser with no signup, no login, no download and no trial of paid features; the Filewise side matches the live version v0.8.0. Dimensions marked unverified here: Price, Do contents leave your Mac?, Confirm before renaming, Undo and deletion. That does not mean the feature is missing, only that the official pages do not state it; we will update after checking.
When to pick Renamer.ai
- You want to rename files in a browser without installing anything, then move to a desktop app when needed.
- You rename many files in bulk with a saved template.
- You are on Windows and Mac and want the same product on both.
When to pick Filewise
- You do not want files uploaded even temporarily; Filewise reads and names on the Mac.
- You want a plan to approve first and an undo log that survives a restart.
- You want a free tool with no plan to choose.
The limits are worth stating too: it needs Apple silicon, the first launch downloads a local model of about 2 GB, and when the local model cannot read a file it keeps the original name instead of guessing, so files it cannot identify still need you.
Migrating or running both
Renamer.ai's templates stay in its own account or app; Filewise needs no import. If you use the web tool for one-off files and Filewise for your regular downloads, both can coexist.
Try it on your own files (10 minutes)
Reviews are only a starting point; what your files look like is what matters. Take 20 real downloads, including invoices, scans, screenshots and English PDFs, and run them through Filewise and Renamer.ai separately without letting either touch the originals. Compare three things: whether the extracted details (issuer, date, amount) are right, whether an unreadable file keeps its name or gets an invented one, and whether a wrong rename can be undone in one step. Then turn the network off and see which one still works.
