With climate change bringing more extreme weather, planning for adequate clean water is more important than ever. SimTanka helps you estimate, collect, store, and monitor rainwater for household use. SimTanka downloads past daily rainfall records for your location so you can see seasonal variations and drought cycles. Use this data to set a realistic daily household water budget tailored to your needs. SimTank then suggests optimal rainwater tank sizes to meet your budget based on the historical rainfall. Large tanks can be expensive, but undersized tanks won't provide enough water. This feature takes the guesswork out of planning tank capacity. Worried about droughts and shortages? SimTanka looks ahead 30 days using forecast data to estimate your available rainwater. You’ll know in advance if rationing may be required. After installing your system, the app becomes your water diary. Log each rainfall event and the amount collected in your tank. Note any water quality issues like odor or debris that require treatment. Record maintenance like filter changes and roof washing. Knowing your water supply and demand helps preparation. Store extra in times of plenty, and conserve when lean times arrive. With climate uncertainty, a good rainwater harvesting plan brings resilience and peace of mind. This app provides the information you need to create a reliable, safe home rainwater system.

Silo lets you control what AI knows. Your memory, your services, your context — in one place, working across every AI model. Silo is the only control layer between your data and the models that use it. Privacy is the foundation. Ownership is the product. Portability is the growth engine. ---- ONE MEMORY, EVERY MODEL Most AI tools trap your history inside a single platform. Your ChatGPT conversations can't move to Claude. Your context resets every time you switch tools. Silo fixes that. Your memory lives in your Silo — on your device, encrypted, portable. Switch between ChatGPT, Claude, Gemini, and more without losing context. One subscription, every model. Nothing gets stuck. ---- A NEW KIND OF FILE When we separated memory from AI models, we created something new: the .silo file. A portable, shareable, structured knowledge package that any AI can query. Share a travel plan that adapts to whoever opens it. Build a company knowledge base grounded in your actual thinking. Package what you know and send it to a collaborator. Authored, not interpreted. Interactive, not static. Yours to share. ---- PRIVATE WHEN IT MATTERS Private Assist runs AI entirely on your device. No internet required. Start a conversation locally, or switch to it mid-conversation when something becomes sensitive. Your data never has to leave your device. But when you choose to use cloud models, Silo always asks before sharing anything. ---- INTELLIGENCE ON YOUR SIDE Silo governs every interaction between your data and AI: · PII scrubbing before data reaches any model · Audit trail of what was shared and when · Instant access revocation · You control your encryption keys Every AI that wants your data asks Silo first. You set the policy. ---- CONNECT YOUR WORLD Silo extends beyond memory. Connect services like Google, Dropbox, and Plaid to your Silo. Any AI you authorize can access them — governed, auditable, revocable. One dashboard, one policy layer, full control. ---- GETS BETTER OVER TIME The more you use Silo, the more your context compounds. Memories connect across conversations. Responses become more personal. Your Silo becomes the most complete picture of what matters to you — owned by you, useful everywhere. ---- Control what AI knows. Own yourself.
