Tana is a cloud outliner built around supertags, fields, and structured nodes. It's powerful, polished, and beloved by people who think in graphs. Projelli is a local-first Markdown workspace with founder-specific templates. The same indie founder might love either one; they're different shapes for different brains. The honest split: Tana for "I want to build a knowledge graph and query it." Projelli for "I want my strategic content as files I own."

Tana's data lives in their cloud. Export is available but the working format is theirs. Projelli's data lives on your machine in Markdown. The compounding-archive value over multiple years tilts toward Projelli for founders building a long strategic record.
Tana has templates (it's actually one of its strengths) but they're general-purpose, user-built. Projelli ships 15 templates designed for founder workflows, each running as a guided AI interview that produces a finished doc. Pitch deck, customer interview synthesis, financial projections, weekly review.
Tana's AI is bundled into the subscription. Projelli is BYOK: you bring your own Claude / OpenAI / Gemini key, switch per conversation. Most users pay less in BYOK API tokens than in a Tana Pro subscription.
Tana's outliner-plus-supertags model rewards a specific working style. If you're a pitch-deck-writer more than a knowledge-graph-builder, the data model is overhead. Projelli's flat-Markdown model fits document-shaped work more naturally.
Tana's signature feature is the ability to define a "supertag" (e.g., #person, #project, #meeting) and then query across all instances ("show me all #project where #status = 'active' and #owner = me"). This is a real superpower for users who think in structured data. Projelli has no equivalent; full-text search only.
Tana's UX for outlining, breadcrumbs, indents, transclusion is the most polished in the category. If you're already a Roam/Logseq/Workflowy user, Tana feels like the natural next step.
Tana has native iOS and Android apps. Projelli is desktop-only.
Tana Pro supports multi-user editing. Projelli is single-user.
| Tana Plus | Tana Pro | Projelli + BYOK | |
|---|---|---|---|
| Year 1 | $120 | $168 | $49 + $60-180 BYOK |
| Year 2 | $120 | $168 | $60-180 BYOK |
| Year 3 | $120 | $168 | $60-180 BYOK |
| 3-year total | $360 | $504 | $229-589 |
The biggest adjustment: you lose the structured-query feature. If your Tana workflow depends heavily on supertag queries, Projelli will feel less expressive. If your Tana workflow is mostly outlining + AI assistance, the migration is straightforward and you'll barely notice.
