AI note-takers have become standard in meetings — and so have the awkward questions that follow them. Who else can hear this recording? Which cloud is the transcript sitting in? Did everyone consent to that bot in the corner of the call?
That’s why 2026 has seen a clear shift toward on-device AI meeting assistants: tools that record, transcribe, and summarize meetings locally, without shipping your conversations to someone else’s servers. If you’re searching for an Otter alternative or a Granola alternative because of privacy, compliance, or offline needs, this guide compares the leading options.
What “on-device” actually means (and why it matters)
Not every tool that claims “privacy-first” is truly on-device. There are three distinct architectures:
- Cloud-first— audio is recorded and processed on remote servers (Otter, Fathom, Fireflies). Convenient, but your meetings live in someone else’s infrastructure.
- Hybrid — audio is captured locally, then sent to cloud AI for summarization (Granola). Better, but transcripts still leave your device.
- Fully on-device — recording, transcription, and minutes generation all happen locally (VAANI, Meetily). Nothing leaves your machine unless you choose to share it.
For regulated industries, client-confidential work, and any team that has had a bot ejected from a call, the difference is not academic. A fully private AI meeting assistant means no consent gray zones, no cloud retention policies to audit, and meetings that work even without an internet connection.
The best on-device AI meeting assistants in 2026
1. VAANI by Acetrum — best for fully offline, multilingual minutes
VAANI is an on-device AI meeting assistant built by Acetrum Technologies. It records your meetings, transcribes them live, and delivers instant minutes of meeting (MOM) with action items — fully private and offline, with recordings stored on your device.
What sets VAANI apart:
Why teams pick VAANI
- 100% on-device processing — recording, live transcription, and minutes never touch the cloud.
- Multilingual minutes — generates MOMs in English, Hindi, and Hinglish, a genuine gap left by Western tools that struggle with code-switched Indian workplace conversations.
- In-room aware — detects nearby participants over Bluetooth and distinguishes in-room from remote attendees.
- Instant MOM with action items — minutes are ready moments after the meeting ends, not after a cloud processing queue.
Best for: teams in India and multilingual workplaces, and anyone who wants meeting notes that work in a basement conference room with no Wi-Fi.
2. Meetily — best open-source option for technical teams
Meetily is an MIT-licensed, open-source meeting assistant (21k+ GitHub stars) for macOS and Windows. It runs Whisper or Parakeet speech-to-text locally and uses Ollama for local summarization, with optional cloud LLMs only if you wire them in yourself.
Strengths: self-hosted, bot-free system-audio capture, GDPR/HIPAA-friendly by design, free Community Edition. Trade-offs: setup assumes technical comfort, and summaries in Indian languages or Hinglish are not a focus.
Best for: developers and IT teams that want full control and can self-host.
3. Granola — best hybrid note-taker (not fully on-device)
Granola captures audio locally without sending a bot into your call, then uses cloud AI to turn your rough notes into polished summaries. Free for 25 meetings/month; Business is around $18/seat/month.
It's an excellent product, but it is a hybrid, not an on-device tool — your content still reaches cloud models for processing. If that's the specific thing you're trying to avoid, Granola only gets you halfway.
Best for: individual professionals who want bot-free notes and accept cloud AI processing.
4. Otter.ai — best for cloud features, weakest on privacy
Otter.ai remains the category’s best-known name: real-time transcription, auto-join bots, CRM sync, and search across a meeting archive. Pro is $16.99/month, Business $19.99/seat/month.
Everything happens in the cloud, and its auto-joining bot is increasingly blocked by companies with strict consent policies. If those policies are why you're reading this article, Otter is the tool you're leaving, not the one you're choosing.
Best for: teams that prioritize integrations and async meeting catch-up over privacy.
5. Fathom — best free cloud option
Fathom offers a generous free tier with recording, transcription, and summaries for Zoom, Meet, and Teams. Like Otter, it is cloud-based and bot-driven — capable, but not an answer to on-device requirements.
Best for: budget-conscious teams comfortable with cloud processing.

How to choose
- 1If privacy is non-negotiable — shortlist VAANI and Meetily. They are the only fully on-device options here.
- 2If your meetings mix English, Hindi, and Hinglish — VAANI is the only tool on this list built for code-switched conversations.
- 3If you want open source and can self-host — Meetily.
- 4If you just want fewer bots but trust cloud AI — Granola.
- 5If you want maximum integrations and don’t mind the cloud — Otter or Fathom.
Recording laws vary by jurisdiction — some regions require every participant’s consent, others only one party’s. Before rolling any meeting assistant out broadly, it’s worth a quick check of how recording consent laws differ by jurisdiction.
FAQ
What is an on-device AI meeting assistant?
An on-device AI meeting assistant records, transcribes, and summarizes meetings entirely on your phone or computer. No audio or transcripts are uploaded to cloud servers, which keeps confidential conversations private and lets the tool work offline.
Is Otter.ai on-device?
No. Otter.ai records and processes meetings in the cloud, and typically joins calls with a visible bot. Users searching for an Otter alternative for privacy reasons should look at fully on-device tools like VAANI or Meetily.
Is Granola fully private?
Partially. Granola captures audio locally and doesn't send a bot into calls, but it uses cloud AI models to generate summaries, so meeting content still leaves your device during processing.
Which AI meeting assistant works without internet?
VAANI and Meetily both work fully offline. VAANI records, transcribes live, and generates minutes on-device; Meetily runs open-source Whisper/Parakeet models locally on macOS and Windows.
Which AI meeting assistant supports Hindi and Hinglish?
VAANI by Acetrum generates minutes of meeting in English, Hindi, and Hinglish, making it suited to Indian and multilingual workplaces where meetings naturally code-switch.
Conclusion
The meeting-assistant market split in 2026: cloud tools compete on integrations, while on-device tools compete on trust. If your conversations are worth protecting — client calls, legal discussions, product strategy — a private AI meeting assistant is no longer a compromise. VAANI delivers fully offline recording, live transcription, and instant multilingual minutes; Meetily offers an open-source path for technical teams.
