Formal Letter Drafting Assistant for Banking Requests

Added Nov 2025 3 design docs

Formal correspondence still runs much of banking: customers must write to request statements, dispute charges, close accounts, or update details, and many people struggle to produce the formal register these letters require. An assistant that drafts a correct, complete letter from a few details saves customers time and reduces back-and-forth for banks. The intern builds the assistant in python. A user selects a scenario, such as disputing a charge, and provides the relevant details, and a langgraph workflow structures the drafting process: the scenario is interpreted, required elements like account references, dates, and the specific request are assembled, and a formal letter is composed. Generative AI through openai models writes the letter in an appropriate professional tone, while an agentic-ai layer coordinates the steps and checks that every required element made it into the draft. The output is a ready-to-send letter the user can review and personalize. The project is a well-bounded introduction to AI content automation: the intern learns template-free document generation, completeness checking, and workflow management, and ships a tool with obvious everyday usefulness.

Plain-Language Explanation Generator for Bank Transactions

Bank statements are full of cryptic merchant codes, abbreviations, and reference numbers that leave many customers unsure what they actually paid for. Support teams field a steady stream of questions that could be answered automatically if raw transaction lines were translated into clear, human-friendly sentences. In this project the intern builds exactly that translator. Users supply anonymized banking transactions, and a python program parses each entry, cleans the fields, and passes them through a generation pipeline that uses openai models to produce a short, plain-language explanation of what the transaction likely represents. The workflow is structured with langgraph, which defines the steps from ingestion to explanation, while an agentic-ai coordination layer decides how each record moves through parsing, generation, and output formatting. The finished tool reads a list of transactions and returns an annotated version anyone can understand. Along the way the intern practices careful data handling, prompt design for financial text, and workflow automation, and finishes with a working example of generative AI applied to a genuinely common retail banking pain point.

LLM-Powered News Digest for the Banking Sector

Professionals in banking are expected to stay on top of rate decisions, policy shifts, mergers, and market developments, but few have time to read dozens of articles a day. A concise daily digest that condenses the headlines into a few readable paragraphs is far more practical, and producing one automatically is an ideal introduction to applied language models. The intern builds a summarization pipeline in python that accepts pasted or uploaded banking news headlines and short articles, groups related items, and generates an easy-to-understand digest using openai models. The summarization workflow is organized with langgraph, giving the process explicit stages for collection, grouping, generation, and formatting, while an agentic-ai layer coordinates how items flow between those stages and retries or refines weak summaries. The output is a clean text digest that highlights what happened and why it matters to the sector. By the end, the intern understands news aggregation, prompt design for faithful summarization, and multi-step workflow orchestration, and can demonstrate a practical generative AI tool aimed at a real communication need in financial services.

Agent-Driven Alert Drafting for Banking Compliance Updates

When regulators publish new rules or amend existing ones, compliance teams at banks must quickly understand what changed, decide who is affected, and circulate clear internal alerts. Doing this by hand for every circular and amendment is slow and error-prone, which makes it a strong candidate for AI-assisted automation. The intern builds a pipeline in python where users paste or upload recent regulatory updates and compliance changes. A workflow defined in langgraph moves each document through stages for parsing, relevance assessment, summarization, and alert drafting, while an agentic-ai layer coordinates the stages and decides when a summary needs another pass. Generative AI through openai models turns dense regulatory language into short, actionable alert messages and longer explanatory summaries, and the system assembles everything into text-based alert reports ready for distribution to affected teams. The project teaches regulatory monitoring practices, faithful AI summarization of high-stakes text, and multi-step workflow automation. The intern finishes able to show a working compliance tool and to explain the safeguards needed when generative AI drafts security-sensitive communications.
