Didon vs Orb

Didon and Orb are both personal assistants tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Didon

Didon runs as a background process on Mac, takes periodic screenshots, and feeds them through a locally-hosted Qwen-3-VL:2b model that writes a structured work journal without any manual input. You define your projects and activity categories upfront; the AI slots every window, file, and task into that context as the day progresses. The resulting logs are queryable in plain language and exportable to CSV for billing or reporting. The local-only architecture means your screen data never leaves the machine — a meaningful distinction if you're working on client material under NDA. The single-device license and Mac-only availability are hard ceilings for anyone working across machines or on Windows.

Orb

Orb Backend is the open-source Python server that powers Orb, a personal AI assistant built around two ideas most tools skip: the assistant should…

Pros	All screen analysis runs locally via Qwen-3-VL:2b, so screenshots and work data never reach an external server — which means client confidentiality obligations do not conflict with using the tool. Context-aware categorization lets you define your own project names and activity types upfront, so the AI logs time against your actual work structure rather than generic app categories you have to remap later. Auto-launch and auto-pause tied to system sleep means tracking starts from the first minute and stops the moment you step away, so idle time does not inflate your reported hours. Plain-language queries against the work journal let you ask 'how much time did I spend on Acme this week' without building a report — which matters on a Friday when a client asks and you need an answer in two minutes. CSV export of daily logs is included without restriction, so billing reconstruction and end-of-month invoicing do not require a manual audit of your own memory.	—
Cons	The license covers installation on one machine only. If you work across a laptop and a desktop on the same day, one machine goes untracked — there is no sync or secondary-device option, and the only workaround is running separate instances under separate purchases. Windows support does not exist in the shipping version — only a waitlist. A team where even one member is on Windows cannot standardize on Didon, and those users have to maintain a separate tracking workflow entirely. The natural language query interface operates against the locally stored log files, but there is no described API or external integration path. Teams that need time data flowing into a project management tool, accounting system, or calendar will be copying CSV exports by hand until integrations ship — a task the vendor lists as upcoming but not yet available. The local LLM is fixed at Qwen-3-VL:2b. There is no described option to swap in a different model if analysis accuracy on your specific workflow proves inconsistent. Teams that try the tool and find categorization errors on niche technical work have no tuning lever beyond adjusting the context configuration.	—

Is Didon better than Orb?

It depends on your workflow. Use the side-by-side attributes (pricing, open source, API, self-hosted, platforms) to decide. AIDiveForge does not rank a universal winner — we publish verified facts so you can choose.

Didon vs Orb: which should I pick?

Pick Didon if its pricing model, openness, or platform fit matches your constraints; pick Orb otherwise. Check free-trial availability on each listing if you want to test before committing.
