Otter Alternative

Otter is a cloud transcription service built around its web app. Cloak keeps transcription local and adds a live, invisible copilot. Here's the trade-off.

The category

Otter popularized live transcription for meetings, with a polished web app and cloud storage for every recording. Cloak overlaps on transcription but starts from a different principle: your audio and transcript stay on your device, and the product's real job is helping you respond in the moment.

Where Cloak differs

Local-first transcription

Cloak captures system audio and transcribes it on your side. The conversation isn't uploaded to a cloud account you log into later — it lives with you.

An overlay, not just an app

Instead of a separate browser tab to glance at, Cloak's transcript and answers float in an overlay that's invisible to screen capture. You stay in the call; the help comes to you.

Live answers, grounded in your context

Otter transcribes and summarizes; Cloak also drafts what to say next, grounded in your résumé, your notes, or a dossier of the company you loaded. Transcription is table stakes — the answer is the point.

Your keys, open client

Bring your own OpenAI, Anthropic, Gemini, or Groq key (free forever), or use a managed plan. The desktop client is open source and auditable.

When Otter still wins

If you want a mature, hosted transcription service with shared cloud folders, a big mobile app, and team-wide search across every past meeting in one place, a cloud transcriber is the better fit today. Choose Cloak when you want local-first privacy and real-time help, not a cloud archive.

How to install Cloak

macOS · Windows · Linux

  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.
    This item is on the disk image.

    Cancel
    OK

    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.
