Your AI Needs Somewhere To Keep Your Books. Solarium is the ledger your AI works in.
Built For AI. Every part of Solarium is a tool your AI can use.
Don't Vibe Code Your Books. A real double-entry ledger. Bank feeds via Plaid, receipts and sales tax already work.
Your Accountant Still Fits In. Excel exports at year-end, and QuickBooks sync if they want it.
Text The Receipt. Toss The Paper. Solarium reads it and matches the charge. Then you or your AI confirms.
