Fireflies Alternative

Fireflies is a cloud notetaker bot that summarizes after the fact. Cloak is local-first and works live. Here's how they differ where it counts.

Same goal, opposite defaults

Fireflies and Cloak both want to free you from frantic note-taking. Fireflies does it by sending a bot into your meeting and storing the recording and transcript in its cloud. Cloak does it from your own machine, with no bot in the room and no Cloak-side recording — and it also helps you during the call, not only after.

Where Cloak differs

No meeting bot

There's no "Fred" or notetaker joining the participant list. Cloak listens to system audio locally, so attendees never see a third party in the call.

Local-first storage

Transcripts and notes live on your Mac. Only the text you prompt against goes to the AI provider you chose — your own key, or a managed plan. Nothing is retained on Cloak's servers by default.

Live, not just retrospective

Beyond the summary, Cloak drafts answers in real time from an invisible overlay — objection handling, exact phrasing, a recap if you joined late — which a pure recorder can't do.

Open source and BYOK

The desktop client is open source, and the free tier is bring-your-own-key forever. You're not renting access to a transcript you already recorded.

When Fireflies still wins

If you specifically want a hosted system of record that auto-joins every calendar meeting, stores every recording centrally, and integrates with a long list of CRMs out of the box, a cloud notetaker fits that shape better today. Choose Cloak when ownership, privacy, and live help matter more than a central cloud archive.

How to install Cloak

  1. 1

    Extract the ZIP

    Open Cloak.zip from your Downloads folder. Double-clicking it will extract automatically.

  2. 2

    Move to Applications

    Drag Cloak.app into your /Applications folder.

  3. 3

    macOS security check

    macOS may warn that it can't verify the developer. This is normal for unsigned indie apps — it's not malware.

    "Cloak.app" can't be opened

    Apple cannot check it for malicious software.

    If you see this, use the fix in Step 4 below — it removes the quarantine flag instantly.

  4. 4

    One-line fix (if blocked)

    Open Terminal (press ⌘ Space, type "Terminal"), paste this command and hit Return:

    Terminal — zsh
    $ xattr -cr /Applications/Cloak.app

    This removes the quarantine attribute macOS attaches to downloaded files. Cloak's source is open source — inspect it any time.
