How Your Data Truly Flows

No black boxes. We split the lifecycle into two isolated pipelines: Rule Learning (Audited AI) and Monthly Batch Processing (100% Offline).

01

User Input Pair

Provide a single representative statement and your preferred format:

  • πŸ“„ Sample_Statement.pdf
  • πŸ“Š Desired_Output.csv
  • πŸ’¬ Optional user prompt instructions
βœ“ Completely local file ingest
Local Privacy Barrier
02

On-Device PII Redaction

Before calling any external model, the on-device regex gate unconditionally sanitizes all sensitive client markers:

Account #: 123456789 β†’ **** 6789
Routing #: [REDACTED]
Client Name: [CLIENT_NAME]
Address: [REDACTED_ADDR]
βœ“ Executed strictly in local RAM
03

100% Auditable AI Prompt

You configure your personal API key (OpenAI / Claude / DeepSeek / local Ollama). Inspect the exact prompt payload before sending:

// Human Audit Panel
POST api.anthropic.com/v1
Payload: Sanitized few-shot pairs + structural extractor prompt
βœ“ Zero data retained by middleman
04

Deterministic Rule Saved

The model outputs a deterministic, human-readable rule file. Saved permanently to your local disk:

Chase_Checking.rule.json
Contains: line-wrap regex, vendor map dictionary, math reconciliation rules
βœ“ Generated once, reused forever
πŸ›‘οΈ ZERO-PII GUARANTEE

Every Single Byte Sent to AI is 100% Auditable.

Unlike closed SaaS that secretly uploads your PDFs to unknown cloud workers, LocalStatement puts an audit gate between your files and the AI model:

βœ“
Pre-Flight Audit Modal:

Clicking "Extract Rule" pauses execution to present the exact sanitized JSON/text payload for human review.

βœ“
Only Few-Shot Examples Sent:

We don't send 50 pages of statements. Only 5~10 token lines are needed to infer the layout and regex.

βœ“
OS Keychain Key Storage:

Your OpenAI/Anthropic/DeepSeek API Key is saved directly in macOS Keychain / Windows Credential Vault.
