What is Delta Chat?

Delta Chat is quietly replacing its email identity with relays

Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.

What is Grain?

Grain adds consent controls and rule-based privacy as its meeting data reaches more AI tools.

Grain's October release lets workspaces flag meetings as sensitive by rule and skip auto-sharing them, adds recording consent controls, and brings back a mobile beta. It follows August's Voice Signatures, which label speakers by voice so shared-mic and in-person captures attribute correctly. Earlier in the year Grain shipped an MCP server and a ChatGPT integration.

Delta Chat vs Grain: editorial side-by-side

D5.0

Delta Chat is quietly replacing its email identity with relays

◆ Current state

Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.

◆ Where it's heading

The project is removing email from what users see and from how they think about identity, with relays taking its place as multi-path infrastructure. Fetching from every relay and sending through the fastest one treats a relay as replaceable, which matters for a federated messenger. Around that, the client keeps closing feature gaps with mainstream messengers through pinning, channel reactions and better group notification handling.

◆ Prediction

Expect further relay management work, as the core notes show this is where the structural change is. Channels are the next most active surface, with reaction privacy already changing there.

2.5

Grain adds consent controls and rule-based privacy as its meeting data reaches more AI tools.

◆ Current state

Grain's October release lets workspaces flag meetings as sensitive by rule and skip auto-sharing them, adds recording consent controls, and brings back a mobile beta. It follows August's Voice Signatures, which label speakers by voice so shared-mic and in-person captures attribute correctly. Earlier in the year Grain shipped an MCP server and a ChatGPT integration.

◆ Where it's heading

Grain spent the first half of 2026 exposing meeting data to AI assistants, and is now adding the governance that wider exposure needs: consent, sensitivity rules and controlled sharing. Release cadence has slowed to roughly one announcement every month or two.

◆ Prediction

Further admin and privacy controls around what AI tools can read are the likely next step; the entries do not show a timeline for the mobile app leaving beta.
