Luffy
Choose Luffy when the bottleneck is recurring work such as weekly reports, enrichment, and follow-ups rather than finding documents.
The best Glean alternative depends on what you actually need: Luffy if you want an AI coworker in Slack that does the work, not just finds it; Onyx if you want open-source enterprise search you can self-host; Dust if you want to build custom agents; Microsoft 365 Copilot if your company lives in Microsoft tools.
