Capacities
Capacities is becoming an AI-connected knowledge hub with a real developer API.
A side-by-side editorial comparison of Shortcut and Double — release velocity, themes, recent moves, and the top alternatives to consider.
Shortcut is rebuilding its API for agents and pushing its Korey AI assistant beyond the app.
Two real threads run through the recent log: an API overhaul (coarse-grained token scopes, admin-scoped routes, and a v4 alpha explicitly aimed at agent compatibility) and the Korey AI assistant expanding to a Chrome extension usable on any webpage. Integration and roadmap polish round it out. Note that some recent feed items are brand-guide page content rather than product releases.
Double is compounding weekly on Ask Double, its AI accounting agent
Double is an AI bookkeeping platform for accounting firms, and its recent releases are a near-weekly buildout of 'Ask Double', the natural-language agent that launched in late May. The agent now creates and edits transactions, builds workpapers by reconciling accounts, imports accruals, runs flux analysis, and edits spreadsheets live in chat. The product is deep in an agentic-automation phase, converting manual bookkeeping tie-out into approve-and-post workflows.

Integration and roadmap polish round it out. Note that some recent feed items are brand-guide page content rather than product releases.
Shortcut is preparing its platform for agent-driven use, with scoped tokens and an agent-optimized API v4, while extending Korey outward from inside the app to anywhere the user works. The direction is a project tracker that both AI agents and humans can drive through a controlled API.
Expect API v4 to move from alpha toward general availability with agent-oriented capabilities, and Korey to gain more in-context actions across surfaces beyond the Chrome extension.
Double is an AI bookkeeping platform for accounting firms, and its recent releases are a near-weekly buildout of 'Ask Double', the natural-language agent that launched in late May. The agent now creates and edits transactions, builds workpapers by reconciling accounts, imports accruals, runs flux analysis, and edits spreadsheets live in chat. The product is deep in an agentic-automation phase, converting manual bookkeeping tie-out into approve-and-post workflows.
Each release extends Ask Double from answering questions toward doing the work — transaction posting, workpaper prep, accrual and loan handling, reusable saved 'skills'. The direction is consistent and cumulative: move firms up the chain from data entry to review-and-approve. Much of it is gated to QBO users and higher 'Scale' tiers, signaling a premium-agent monetization path.
Expect continued weekly Ask Double extensions pushing more of the close checklist into the agent — likely deeper reconciliation, reporting, and moving beta features (like loan amortization) to general availability.
