Logseq is the open-source local-first outliner. It's free, privacy-respecting, and beloved by people who think in bullet points and graphs. Projelli is a closed-source local-first AI workspace built for founder writing. They share a philosophy (your data on your machine) and differ on shape (outliner vs document editor) and audience (general note-takers vs indie founders shipping a product). If Logseq's open-source model is non-negotiable, pick Logseq. If founder-specific AI workflows matter more than open-source, pick Projelli.

Logseq has community AI plugins (logseq-copilot, several Claude/OpenAI integrations) but the experience is "install, configure, hope the plugin keeps working." Projelli ships AI as the primary input with founder-specific templates that produce real documents.
Logseq has user-built templates and a strong daily-notes paradigm. Projelli has 15 templates designed for founder work: pitch deck, customer interview, financial projections, weekly review, MVP scope.
Logseq's outliner-first model is a love-it-or-hate-it design. If you naturally think in nested bullets, Logseq is great. If you write in flowing paragraphs (which most founder docs are), Logseq's outliner gets in the way. Projelli is paragraph-first.
If your founder workflow includes editing a Word doc, working in an Excel spreadsheet, or annotating a PDF, Projelli handles these natively. Logseq is text-only without plugins.
Logseq's "assemble your own stack" approach gives flexibility but requires assembly work. Projelli ships a coherent product where AI, templates, search, audio, whiteboard, document handling all work together without configuration.
Logseq is AGPLv3. You can read the source, fork it, run a private build forever. Projelli is closed source. If open-source is a hard requirement, Logseq is the only choice between these two.
Logseq is $0. Projelli is $49 once. For users with no budget, Logseq removes that barrier.
Logseq has iOS and Android apps. Projelli is desktop only.
If you're already a Workflowy / Roam Research / Tana user, Logseq's outliner feels native. Projelli's document editor will feel constraining.
Hundreds of community plugins extend Logseq into specific domains. Projelli has no plugin system.
Logseq's interactive graph visualization of your knowledge graph is a real feature for users who want it. Projelli has backlinks panel but no graph.

This is the easiest migration of any vs-page in this site, since the underlying file format is essentially the same. The biggest adjustment is the editor paradigm shift from outliner to paragraph editor.
