The Otter alternative for recordings that can't leave your computer.

Otter is good at live meetings. But every recording goes to Otter's servers. Ratproof transcribes on your computer, and never receives the file.

What Otter says

Why some organisations block it

CUNY blocked Otter in September 2025 because such tools store CUNY meeting content on unapproved, non-CUNY cloud servers. The University of Nebraska and Morgan State University have also blocked it from their meetings.

In August 2026, a US federal court let several claims in a class action against Otter go ahead, including federal wiretap claims (In re Otter.ai Privacy Litigation). These are allegations. Nothing has been proven.

Which one to use

Otter for live meetings where everyone is fine with a bot and the cloud, or when you need a language other than English, Spanish, Italian or Swedish.

Ratproof when the recording shouldn't leave your computer: a client call, an interview with a source, a research participant, an HR conversation. Or when you just have a lot of files and don't want a monthly cap.

Open Ratproof Free. No account. Nothing uploaded.

Questions

Is there an Otter alternative that does not upload my recordings?

Yes. Ratproof transcribes inside your browser, on your own computer. The recording is never uploaded, and you can check that in the Network tab or by going offline.

Does Otter train its AI on my recordings?

Otter's privacy policy lists training its AI on de-identified audio recordings and transcriptions. Its settings let you choose whether to share conversations for training and human review.

Can Otter work offline?

Otter can keep recording without internet, but its help centre says transcription needs a connection and happens on Otter's servers.

How many files can I import on Otter for free?

Three per account, for life, with 30 minutes per conversation (Otter's Basic plan, October 2026). Ratproof has no limit on free transcription.

Does Ratproof join my meetings like Otter Notetaker?

No. Ratproof never joins a call. You record the meeting, or use a recording you already have, and Ratproof transcribes the file.
