Sentiment‑Driven Transaction Risk Engine Launches as a Code‑Free Streamlit App

SALT LAKE CITY - Jan. 23, 2026 - PRLog -- Sentiment‑Driven Transaction Risk Engine Launches as a Code‑Free Streamlit Application

Salt Lake City, UT – January 23 2026 – Marie Daras LLC today announces the public release of its Sentiment‑Driven Transaction Risk Engine, a Streamlit‑based application that merges real‑time customer sentiment with transactional data to flag high‑value, negative‑sentiment purchases before they result in chargebacks or revenue loss.

Key Features

• Code‑free, open‑source – The entire codebase is released under an MIT license; there are no licensing fees. Users must host the app themselves (or on a paid Streamlit tier if they exceed the free‑tier limits).
• Instant risk alerts – Transactions that cross a configurable monetary threshold and carry negative sentiment are highlighted in real time, allowing fraud teams to intervene immediately.
• Measured financial impact – Internal pilot studies at two midsize retailers demonstrated an average saving of $1,800 per flagged transaction by preventing chargebacks.

Quote from Dawn Daras, Data Scientist, Marie Daras LLC

"Businesses should not have to write custom AI pipelines to protect their bottom line. By releasing the engine as open‑source code, we eliminate licensing barriers; the only cost is the infrastructure you choose to run it on."

How It Works

1. Ingest sales records and any associated customer remarks (chat, reviews, support tickets).
2. Analyze sentiment using a pre‑trained natural‑language model that runs locally within the Streamlit environment.
3. Flag any transaction whose sentiment score falls below a user‑defined threshold and whose value exceeds the set limit.

The solution is intended for organizations that lack dedicated data‑science resources but require immediate protection against costly chargebacks. Because the code is freely available, companies can deploy it on any compatible server—whether on‑premises, a private cloud, or a paid Streamlit tier—without paying for software licenses.

Availability
The Sentiment‑Driven Transaction Risk Engine is available now as an open‑source repository and can be deployed via the "Deploy to Streamlit" button on the project page:
