Six layers that together
run your finances
From the AI foundation to the treasurer. Each layer builds on the last, all wrapped in security that never lets go.
Layer 1 · Foundation
Language models
Leading models (OpenAI GPT-4o for comprehension, vision and reasoning; embeddings for semantic search) form the foundation. We don't train our own models, and we never use your data to train public AI.
Layer 2 · Raw material
Data & integrations
Bank transactions, scanned receipts, expense reports and cloud storage (Dropbox, Google Drive, OneDrive) come together in one isolated environment. Every organization gets its own, isolated data schema.
Layer 3 · Understanding
Context & knowledge
A searchable knowledge base of 501(c)(3) and tax rules, tailored to your organization type and status. Answers aren't generic; they're accurate for your specific situation.
Layer 4 · The core
Agentic harness
This is where the difference lies. Fixed rules and a 5-layer matching engine do the heavy lifting: first exact matches, then fuzzy, then aggregate and pattern. AI only fills in what's left. Predictable, verifiable and explainable, no black box.
Layer 5 · The work
Treasurer's work
Bookkeeping, matching, expense reports, budgets, funds, financial review and 501(c)(3) accountability. You get ready-made tasks the system handles for you, not separate buttons you have to operate yourself.
Layer 6 · At the wheel
Solon & interfaces
Solon guides you step by step with advice backed by the entire stack, on web and mobile. You decide and approve, the system executes.
From bank statement to
accurate books
Four steps the OS handles almost entirely on its own. You stay in control.
-
Connect & collect
Connect your bank, upload or email your receipts, and connect cloud storage like Dropbox, Google Drive or OneDrive. Everything comes together in one isolated environment, with its own isolated data schema per organization.
-
Read & understand
Receipts are read via AI vision: vendor, date, amount and tax. Transactions get context from a knowledge base of 501(c)(3) and tax rules, tailored to your organization type.
-
Matching: rules first, AI last
A 5-layer engine matches bank and receipts through exact, fuzzy, aggregate and pattern matching. Only the last remainder goes to AI. Predictable, verifiable and explainable.
-
Review & approve
Solon makes suggestions with reasoning; you approve. Payments require dual approval, and every action is auditable. Reports are ready for the meeting.
AI you can trust
with your books
Three principles keep the system predictable and you in control.
Rules come before guesswork
Exact rules and patterns come first. Only what's left goes to AI. This keeps most of the work predictable and explainable.
You approve, not the AI
Solon and the engine make suggestions; a human confirms. Payments require dual approval. The AI never acts on its own.
Your data stays yours
US hosting, encrypted storage, and never used to train public AI models. Every action is fully auditable.
What the OS handles for you
Not standalone features, but connected tasks the stack takes on itself.
Receipt scanning
Photos and PDFs are read via AI vision: vendor, date, amounts and tax automatically recognized.
Matching in five layers
Bank and receipts are matched through exact, fuzzy, aggregate and pattern matching. Only the last remainder goes to AI. Result: accurate books with minimal manual corrections.
Automatic matching rules
Solon generates matching rules from your transaction history. New transactions are instantly categorized to ledger account, cost center and fund, consistent and explainable.
501(c)(3) & compliance
An autonomous action service tracks deadlines and obligations and warns you in time. Includes ready-made reporting.
Reports & board insight
From cash book to board reports to financial review, always up to date and ready for the meeting.
Budget tracking
Set budgets per cost center and fund and see what's left in real time. Overruns are visible immediately.

Protection that never lets go
Security and governance wrap every layer of the OS. Your data is never shared with public AI models and never used to train those models. Connections are encrypted, your receipts stay in your own cloud storage, and you keep full control of your data.
Isolated per organization
Every organization gets its own, isolated data schema. Data from different organizations never mixes.
Receipts in your own cloud
Scans and documents are stored in your own Dropbox, Google Drive or OneDrive. Tutelium doesn't store the files itself, you remain the owner.
A human decides, everything auditable
The AI makes suggestions, you approve. Four-eyes approval on payments, roles & permissions, and every action fully traceable.
