Clipdiary vs Ditto: Log Everything or Stay Light?

Most clipboard tools argue about the last week. Clipdiary argues about last year. The vendor site says the program records copies and can retrieve them “even after many years.” That is a different product from Ditto, which is a working history: deep enough to be useful, not framed as a journal.

The title is the decision. Log everything, or stay light.

What Clipdiary is

From clipdiary.com (current 5.7 line):

• Monitors the clipboard and writes a local database
• Formats include plain text, RTF, images (BMP), HTML, files
• Starred clips and labels / folder-like organization
• Snippets for frequently used text
• Local only — “no servers, no clouds”
• Optional AES-256 password on the database
• Portable build
• Trial described as fully functional for 60 days on the download page
• A free personal-use license with conditions (private PC, or income under a stated threshold, or nonprofit). Otherwise buy after the trial.

The homepage’s motivating story is not “paste faster.” It is “what did I copy a month ago when the app crashed.”

What Ditto is

An open-source Windows clipboard extension. Local database. Search. No login, no cloud, no telemetry. Default Ctrl+\`. Free without an income test. The implicit retention policy is “whatever you configure,” not “years, on purpose.”

Side by side

Neither wins capture (ClipClip / ShareX). Neither wins scripting (CopyQ). Neither wins hover drag-out (Edge-Drop). Neither wins vendor cloud (ClipboardFusion Pro).

The privacy cost is the feature

A clipboard journal will contain:

• Passwords copied “just this once”
• One-time codes
• Client names
• Health-portal text
• Draft messages that were never sent

Clipdiary’s AES-256 helps if the disk is stolen and the database file is what the thief takes. It does not help if the PC is unlocked. It does not help if the passphrase is the same as the Windows PIN and written on a note.

Ditto can be just as dangerous if someone sets “keep everything forever” and never prunes. The difference is positioning. Clipdiary *sells* the forever log. People who buy that pitch will keep more, longer.

How Many Items Should a Clipboard Remember? is the ethics page. The short version: more history is more search and more blast radius.

Recommendations if Clipdiary is still the right tool:

• Turn on encryption
• Exclude the password-manager window if the app allows it
• Do not install it on a shared family login
• Do not enable Windows history at the same time
• Have a delete habit, even in a “forever” product

Should You Enable History If You Only Copy Passwords?

Who should pick Clipdiary

• Incident-style work: “the quote was on the clipboard in March”
• Researchers who already treat the PC as a filing cabinet and accept the filing cabinet’s risks
• People who want snippets and history in one paid-or-free-personal app, without CopyQ’s learning curve
• Anyone who specifically wants a password on the clip database

Who should not:

• Shared household accounts
• Password-heavy days
• Users who have not yet tried Ditto
• Anyone who thought “unlimited” was free of tradeoffs

Pasteboard also markets unlimited history. It is a simpler modern list, not an encrypted journal. Different cousin.

Who should pick Ditto

Almost everyone who outgrew Win+V.

• Search last week
• Survive reboot
• Stay local
• Avoid a license decision
• Keep the UI small

If Ditto’s database grows ugly, lower the cap. That is easier than deleting a year of Clipdiary because a threat model changed.

Licensing is part of the comparison

Ditto: use it at work, at home, in a lab, unless the *organization* forbids third-party software.

Clipdiary: read the free-license page. The vendor restricts free use on workstations, on freelance/home-office machines, and above a stated income. A 60-day trial is the evaluation path; after that, pay or comply with the free terms.

That is not a smear. It is why “Clipdiary is free like Ditto” is false for many readers of this site.

Performance and “log everything”

A multi-year image-inclusive database is not free in disk or in search latency. Clipdiary can store BMPs and files. That is useful and heavy. Ditto users who copy huge bitmaps see the same physics.

If the archive is really about text, configure images off or cap them. If the archive is about files, a real backup (File History, a Git repo, a documents folder) is a better journal than the clipboard.

Win+V will never be this archive: 25 items, reboot wipe, no files. What Windows Clipboard History Will Never Do

Portable copies

Both ship portable builds. A portable forever-log on a USB stick is a high-value theft target. If Clipdiary portable is used, enable AES-256 and do not leave the stick in a laptop bag with the passphrase in a text file next to it. Ditto portable has the same disk-theft problem without the encryption headline; BitLocker the machine instead of romanticizing USB workflows.

Snippets versus history

Clipdiary’s snippets tab is a second reason people pick it: canned replies that are not “whatever was copied last year.” Ditto users often fake that with favorites. A real snippet tool (the mail client, the help desk, Espanso) is still cleaner if snippets are the *only* extra need.

Do not buy Clipdiary solely for snippets if the archive half will never be used. That is paying (or accepting a heavy journal) for a notes file.

Conversely, do not refuse Clipdiary solely because snippets exist. They are optional. The archive is the identity.

A decision in four lines

1. Need last week, locally, no drama → Ditto
2. Need last year, on purpose, and will encrypt and prune secrets → Clipdiary
3. Need last year *and* scripts → CopyQ, not a journal app
4. Need nothing after shutdown → Win+V

Stay light until a real missed-year incident says otherwise. Most people who think they want a journal wanted search.
