A chat function would have made the Proton package more complete - and it would also have been extremely helpful for the users. It would also have made all of us much less dependent on American solutions and databases.

Genuinely would make Proton a more complete package for our business, it would be fantastic to have 1 provider for all our uses (Chat/Email/Drive/Docs/Spreadsheet/Calendar/Pass).

Now we're forced to use other alternatives (Slack/Email) to communicate internally, I also understand there's an AI bubble so everyone's focused on that but at least for us that provides no value at all compared to what a Chat/Messaging application would.

I want this, please

I want this, please make it be true

We need secure European option for Signal

To start with, just need (urgently) a straightforward app that even people not computer literate can use, with voice would be best. Easy importing from Google contacts, if that would be safe. Closing app deletes messages automatically. Able to send/receive pictures and links. The app would be great for finances, health info, business, and military. Thank you.

Agree, this is good

if you make it like signal (but better) then **** yeah

I don't think a Proton Chat app would serve regular consumers very well but this would be a godsend for privacy-oriented businesses. I hope that someday the Proton suite will make sense for my business. Currently, Proton Pass and VPN are the only applications that I could switch to. Proton Chat with good integration with Proton Calendar and Drive would provide enough value for us to switch.

I think this should be done smarter way. We dont need another Signal.
What we need is federative decentralized communication standards which will allow users to send message from Proton Messenger to Telegram / Pixelfed / Mastodon / Signal etc. it could use Signal protocol.
Why we can send email from gmail to icloud or proton, but we cannot pm from signal to any other messenger? This would be real freedom.

Is Meet going to be the app that will incorprate chat? It's funny how this has been around since 2015, but the app that got built was a video conferencing platform with chat as a sidebar.

100% agree. Chat needed along with spreadsheets. Then I can move the business over.

Maybe instead of creating yet another IM you could acquire DeltaChat https://delta.chat/

I don't know if this is already planned for Proton Meet, but I would like to see a “Proton Chat.” I want to be able to chat privately and without worries, but still conveniently. That would be very practical, especially for people like me who want to stay in the Proton “universe” and don't have to chat via another provider.

Hi Proton Team,

I’m a long‑time Proton user and I appreciate the strong focus on privacy that you bring to email, VPN, Drive, and now Lumo. I’d like to suggest adding a dedicated, privacy‑first chat/messaging application to the Proton suite.

What I’m Asking For
A secure instant‑messaging app that offers:
* End‑to‑end encryption for all messages, voice calls, and video calls (similar to Theema’s or Signal’s model).
* Self‑destructing / disappearing messages and optional “ghost mode” where no conversation history is stored.
* Cross‑platform support (iOS, Android, macOS, Windows, Linux, and web).
* Seamless integration with existing Proton services:
* Use the same Proton account for login.
* Attach files directly from Proton Drive.
* Optionally route AI‑assisted replies through Lumo (e.g., draft replies, summarize long threads).
* Group chat capabilities with granular admin controls and invitation links.
* Two‑factor authentication and device management consistent with Proton’s security standards.

Why This Matters
* Completes the privacy ecosystem: Users already rely on Proton for encrypted email and VPN; a chat app would let them keep all real‑time communications under the same trusted umbrella.
* Reduces reliance on third‑party messengers that harvest metadata and content.
* Leverages existing infrastructure: Proton already runs zero‑access encryption and secure key management; extending this to messaging is a natural next step.
* Competitive advantage: Few mainstream providers offer a fully integrated, privacy‑first suite covering email, cloud storage, VPN, and now chat.

Possible Use Cases
* Teams collaborating on sensitive projects without exposing data to commercial messengers.
* Families sharing personal moments while preserving privacy.
* Individuals needing a secure channel for health, legal, or financial discussions.

I believe a Proton chat app would resonate strongly with the community that values security and privacy. Thank you for considering this suggestion—I look forward to seeing how Proton continues to expand its privacy‑first toolbox.

Best regards,

This idea is from 2015.... please get this created already!

It's been under review for 10 years and still hasn't been accepted? It's hilarious, ha ha ha. "We designed our encryption flexible enough to allow for chat. But we're not planning it for the summer. Probably in 2016." What year? 2025, and it's still coming. :/

'Proton Chat' should be a Matrix client with a European based Synapse server, free for all. Proton Unlimited, Duo & Family should get access to bridges like SMS, Signal, Telegram etc.

Would love if they just host Matrix instance. It's not hard, they won't have to develop anything new, and Matrix is already secure.

It should be similar to Telegram, but login to register by email
