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 Rocket.Chat?

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

Shortwave vs Rocket.Chat: editorial side-by-side

S0.0

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.

Rocket.Chat logo6.3

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

◆ Current state

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

◆ Where it's heading

9.0 is in stabilization: each candidate is smaller than the last, and the load fixes are being carried to the LTS line rather than held for the major. Native LiveKit video is being promoted step by step, from alpha to beta and now as the named default provider option.

◆ Prediction

With rc.7 down to a handful of fixes, 9.0.0 GA is the next likely release, followed by further 8.9.x LTS patches carrying the same fixes.
