Shortwave vs SimpleX Chat
A side-by-side editorial comparison of Shortwave and SimpleX Chat — release velocity, themes, recent moves, and the top alternatives to consider.
Shortwave vs SimpleX Chat: at a glance
What is Shortwave?
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
What is SimpleX Chat?
SimpleX's v7.0 beta grows a private messenger into a public-channel network
SimpleX is deep in the v7.0 beta cycle, and the through-line is channels. Successive betas have added subscriber and contributor roles, CLI channel connections, obfuscated-link moderation, and now registered SimpleX names for channels and businesses. The metadata-free privacy model stays intact, but the product is growing a public broadcast surface it didn't previously have.

Shortwave keeps folding autonomy into the inbox, one AI action at a time.
◆ Current state
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
◆ Where it's heading
The direction is a steadily widening action surface: MCP connectors to external tools, AI Memories, voice, and now trigger-based automation all frame email as an agent runtime rather than a reading pane. Model choices track the frontier closely — Claude 3.7 to Sonnet 4 to the 4.6 family — keeping capability tied to whatever the best available model can do. The team ships broadly across web, desktop, iOS, and Android each cycle.
◆ Prediction
The next moves most likely deepen autonomous execution — more trigger types and tighter loops where the assistant acts with less confirmation — rather than adding new surface features.

SimpleX's v7.0 beta grows a private messenger into a public-channel network
◆ Current state
SimpleX is deep in the v7.0 beta cycle, and the through-line is channels. Successive betas have added subscriber and contributor roles, CLI channel connections, obfuscated-link moderation, and now registered SimpleX names for channels and businesses. The metadata-free privacy model stays intact, but the product is growing a public broadcast surface it didn't previously have.
◆ Where it's heading
Each beta hardens the channels stack — roles, moderation, web previews, relay management — while chipping away at connection stability and delivery in large groups. The move to registered SimpleX names for channels and business accounts points toward discoverable, addressable identities, a notable shift for a network built on unaddressed contact. The remaining betas look aimed at stabilizing delivery and finalizing the naming and business layer before a 7.0 stable.
◆ Prediction
The next beta most likely locks down the SimpleX names registration flow, currently gated behind test infrastructure, and continues group-delivery stability work ahead of a 7.0 stable release.
