Shortcut vs Mumble: at a glance
What is Shortcut?
Shortcut redesigns its API for AI agents and pushes Korey beyond its own walls.
Shortcut is making concrete bets on agent-based work. API v4 entered alpha on May 12 with explicit framing around expanded capabilities and 'agent compatibility' — a positioning shift, not just a version bump. Their in-house AI assistant Korey is expanding outward: right-click access in February, then a dedicated Chrome extension in April that runs on any webpage. Around the strategic work, smaller improvements (Teams on Roadmap, March's SLA Alerts) keep shipping, alongside feed-noise from brand-guide pages being scraped as if they were releases.
What is Mumble?
Mumble closes out the 1.5 series with another stable patch while 1.6.x waits in the wings.
Mumble is in late-stage maintenance on the 1.5 series, with v1.5.901 landing as the fourth stable patch since 1.5.634 shipped in May 2024. A 1.6.x release candidate appeared in March 2026, kicking off the project's next major branch in parallel. The same long-standing macOS notarization and gaming-overlay compatibility issues recur in every release note, with no resolution in sight.

Shortcut redesigns its API for AI agents and pushes Korey beyond its own walls.
◆ Current state
Shortcut is making concrete bets on agent-based work. API v4 entered alpha on May 12 with explicit framing around expanded capabilities and 'agent compatibility' — a positioning shift, not just a version bump. Their in-house AI assistant Korey is expanding outward: right-click access in February, then a dedicated Chrome extension in April that runs on any webpage. Around the strategic work, smaller improvements (Teams on Roadmap, March's SLA Alerts) keep shipping, alongside feed-noise from brand-guide pages being scraped as if they were releases.
◆ Where it's heading
Shortcut is positioning itself as the project-management surface that AI agents naturally operate against, not just a PM tool with AI features bolted on. Korey is being pushed from in-app helper toward general-purpose web assistant; the API is being redesigned with external agent consumers in mind. That's a coherent strategic stance the bigger PM players — Jira, Linear, Asana — have not yet made as explicitly. Underlying release cadence stays steady, suggesting these are strategic plays, not panicked pivots.
◆ Prediction
Expect API v4 to surface MCP-style tooling endpoints and structured action surfaces aimed squarely at agent frameworks. Korey's Chrome extension is likely a stepping stone toward a 'Korey anywhere' positioning — deeper integrations with browser, email, and calendar are the natural next dominoes.
Mumble
2.5COLLAB
Mumble closes out the 1.5 series with another stable patch while 1.6.x waits in the wings.
◆ Current state
Mumble is in late-stage maintenance on the 1.5 series, with v1.5.901 landing as the fourth stable patch since 1.5.634 shipped in May 2024. A 1.6.x release candidate appeared in March 2026, kicking off the project's next major branch in parallel. The same long-standing macOS notarization and gaming-overlay compatibility issues recur in every release note, with no resolution in sight.
◆ Where it's heading
The project is gradually winding down the 1.5 line while 1.6.x stabilizes, running both branches simultaneously rather than forcing users onto an unfinished new series. Release cadence is months between stable patches and has held that way for years. Long-running platform issues (macOS signing, anti-cheat overlay blocks) continue to dog every release, suggesting maintainers have effectively conceded that ground.
◆ Prediction
Expect one or two more 1.5.x stable patches before 1.6.x reaches its own first stable. The same known-issues list will almost certainly carry into the 1.6.x line.
