Regulatory change extraction · Prototype

Start with the change. Keep the source in view.

Merval is an early prototype for extracting changes from Turkey's Official Gazette. Explore a recorded run below. Claude-assisted impact briefs are planned, and our first bank pilot is in preparation.

The problem

Regulation moves daily. Reading it is still manual.

Compliance and legal teams spend hours reading amendments line by line, comparing them with the previous text, and working out who in the bank is affected.

Dense, scattered text

Changes arrive as amendments to amendments, and the real meaning only shows up against the previous version.

Impact is the hard part

Knowing what changed is not enough. Teams need to know which processes, products and policies it touches.

Every answer must be defensible

An assessment is only useful if a reviewer can trace each claim back to the exact article.

How it works

Extraction first. Impact briefs next.

01
Current prototype

Read an amendment

The recorded run uses a public Official Gazette publication as its source.

02
Current prototype

Extract with quotes

Show the replacements found in the amendment, alongside source clauses and unresolved fields.

03
Planned

Support impact review

Develop Claude-assisted impact briefs with compliance professionals through a bank pilot.

Principles

Designed around a reviewer's judgment.

Public sources

This prototype works with publicly published regulation. The recorded run uses no customer or internal bank data.

Source text in view

Read the quoted amendment clauses and open the official publication alongside the extracted changes.

Specialist review

Dates, interpretation and operational impact need a specialist's assessment before use.

Visible limits

Unresolved fields and checks that were not run stay visible in the recorded output.

Who it's for
