AI Builds the Rules. PHP Executes at Scale.✎ Edit

Most discussions around Document AI focus on using AI to process every document.

We took a different approach.

At Ainna, AI is used to build the parser, not to run the parser.

When a new bank statement format is introduced, AI analyses the document and generates four reusable components:

✅ Parsing Rules – Identify transaction tables, dates, descriptions, debit, credit, and balances.

✅ Cleaning Rules – Correct OCR issues, merge fragmented rows, remove headers and footers, and normalize the extracted data.

✅ Validation Rules – Verify running balances, detect duplicates, validate transaction integrity, and check data consistency.

✅ Confidence Scoring – Assign a confidence score to every compiled statement based on extraction and validation accuracy.

Once generated, these rules are stored as reusable rule sets.

From that point onward, our PHP execution engine processes future statements using the saved rules-without calling AI again.

The result is:

• ⚡ Faster execution

• 💰 Significantly lower AI costs

• 📊 Consistent outputs

• 🚀 Scalable processing for millions of statements

AI is only invoked when confidence drops below a user-defined threshold.

For example:

• Confidence ≥ 95% → Execute using existing rules.

• Confidence < user threshold → AI analyses the document, refines the rules, or creates a new parser version.

This creates a continuous improvement loop where AI enhances the system only when required, while routine processing remains deterministic, lightweight, and cost-efficient.

AI builds the intelligence. PHP executes it at scale.

For high-volume document processing, this architecture is often more economical, predictable, and easier to maintain than sending every document through an LLM.
