QuidClaw

Zero-barrier personal CFO.

Local-first. Privacy by design. Your data never leaves your machine.

QuidClaw turns any AI coding tool into a personal finance manager. It combines a CLI for Beancount accounting operations with Agent Skills (agentskills.io standard), so the AI knows exactly how to record transactions, import bank statements, detect anomalies, and generate reports. You talk to your AI in natural language — in any language — and it handles the bookkeeping. Works with Claude Code, Gemini CLI, OpenAI Codex, Cursor, or anything else that supports agent skills.

"I had lunch for $15, paid with my debit card"

The AI records a $15 lunch expense from your bank account. No forms, no menus, no learning curve.

Why QuidClaw

• Privacy first — Everything runs locally. No cloud, no telemetry, no third-party access. Your financial data is plain text files on your machine.
• You own your data — Beancount plain text format. Version control with git. No vendor lock-in. Export, migrate, or audit anytime.
• Zero barrier — Talk to your AI the way you talk to a friend. Say "I paid rent today, $2400" or "spent €30 on groceries" and it just works.
• Works with any AI — Not locked to one tool. Claude Code today, Gemini CLI tomorrow. Skills are installed to each platform's native directory.
• Real accounting engine — Powered by Beancount V3 with double-entry bookkeeping, multi-currency support, and a query language (BQL).

The AI reads the generated entry file (e.g. CLAUDE.md), discovers the installed skills, and uses the quidclaw CLI for accounting operations (transactions, balances, queries, reports). File operations — notes, document organization, inbox management — are handled directly by the AI using its native tools. Five Agent Skills teach the AI how to handle complex multi-step tasks like onboarding, bill import, daily routines, and financial review.

Features

• Natural language input — Speak any language. The AI translates your words into structured transactions.
• Multi-currency — USD, EUR, GBP, JPY, or any currency. Mixed-currency accounts supported.
• Bill import — Drop bank statements or receipts into inbox/. The AI parses, deduplicates, and records them.
• Duplicate detection — Catches double-charges, repeated subscriptions, and already-imported transactions.
• Document organization — AI files documents from your inbox into a clean documents/YYYY/MM/ archive.
• Financial knowledge base — Living notes for profiles, payment calendars, asset tracking, and decision logs.
• Anomaly detection — Flags duplicate charges, subscription price changes, spending outliers, and unknown merchants.
• Monthly reports — Income vs. expenses, category breakdowns, month-over-month comparisons, top expenses.
• BQL queries — Full Beancount Query Language access for custom analysis.
• Reconciliation — Balance assertions to verify your data matches your bank.
• Email integration — Forward bills to a dedicated email address. QuidClaw syncs and processes them automatically.
• Audit trail — Every transaction traces back to its source document. Processing logs record what was extracted and confirmed.
• Extensible data sources — Pull data from email (AgentMail), with architecture ready for future sources (bank APIs, broker integrations).
• Git backup — Automatic version control with multi-remote backup. Every change is committed and pushed to GitHub, Gitee, or any Git host. Supports Git LFS for binary files.

Quick Start

OpenClaw (recommended)

pip install quidclaw
quidclaw init --platform openclaw

This creates a dedicated financial agent. Connect it to Telegram, WhatsApp, or any supported chat app. The agent handles onboarding, daily routines, and monthly reports automatically.

Claude Code

pip install quidclaw
mkdir ~/my-finances && cd ~/my-finances
quidclaw init --platform claude-code
claude

Other AI Tools

pip install quidclaw
mkdir ~/my-finances && cd ~/my-finances
quidclaw init   # interactive platform selection

Usage Example

You:   How much did I spend this month?
AI:    Let me check... [runs quidclaw monthly-summary 2026 03]

       Total expenses for March: $4,285.50

       Rent         $2,400.00  (56.0%)
       Dining       $540.00    (12.6%)
       Groceries    $380.00    (8.9%)
       Transport    $275.50    (6.4%)
       Other        $690.00    (16.1%)

       That's $320 more than last month (+8.1%), mainly from dining.

You:   Lunch was $15, paid with my debit card
AI:    Done. [runs quidclaw add-txn ...]
       Recorded: 2026-03-20 Lunch $15.00 (Assets:Bank:Checking → Expenses:Food:Dining)

You:   Put my bank statement in the inbox, help me import it
AI:    [loads the quidclaw-import skill]
       [scans inbox/, parses the CSV, deduplicates, records 47 transactions]
       Found 52 transactions in the statement. 5 were already recorded.
       Imported 47 new transactions totaling $3,892.10.
