Pick the right tool. Sometimes that isn't us.
Cloud assistants are better at frontier reasoning. Local chat apps are better for one person tinkering. Gryndara is for a small team that needs work produced from its own documents without those documents leaving the building.

Choose Gryndara when…
- Several people need the same AI setup on shared documents.
- The output is a file (summary, proposal, report), not a chat answer.
- Client or regulatory obligations mean documents can't go to a third party.
- You want a fixed cost that doesn't rise with usage.
Choose something else when…
- You need frontier reasoning on novel problems → a cloud model.
- You're one person who wants to try many models → Jan or LM Studio.
- You're a developer wiring a model into your own code → Ollama directly.
- Your team already lives entirely in Microsoft 365 and data residency there is acceptable → Copilot.
