Zettlr vs Double: at a glance
What is Zettlr?
Zettlr added admonitions after six years, then spent a release fixing its updater.
Zettlr 4.8.0 brought admonitions, a feature six years in the making, plus translation updates and a fix for a long-standing logic bug in search. 4.9.0 followed in late October to stop a false 'Update failed' error introduced by 4.8, drop macOS 12 and old Ubuntu support, distrust the eMudhra TLS certificates and render reference-style images.
What is Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
Zettlr vs Double: editorial side-by-side
Zettlr
2.5COLLAB
Zettlr added admonitions after six years, then spent a release fixing its updater.
◆ Current state
Zettlr 4.8.0 brought admonitions, a feature six years in the making, plus translation updates and a fix for a long-standing logic bug in search. 4.9.0 followed in late October to stop a false 'Update failed' error introduced by 4.8, drop macOS 12 and old Ubuntu support, distrust the eMudhra TLS certificates and render reference-style images.
◆ Where it's heading
Releases arrive roughly monthly and alternate between a headline writing feature and cleanup of the previous one. The app is tracking Electron's platform support, so older operating systems will keep falling away.
◆ Prediction
A small 4.9.x fix release or a feature-led 4.10 in about a month fits the pattern; the entries don't hint at its contents.
Double
8.8COLLAB
Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
