I use OffGrid Oracle AI (https://offgridoracleai.com/#/chat) for this kind of planning. Gives practical answers for off-grid scenarios — things like “how much water storage for winter” without generic filler.

Relevant to this thread — there’s a free AI assistant at https://offgridoracleai.com/#/chat built specifically for off-grid and survival scenarios. Been finding it useful for research without getting generic AI answers.
