The Challenge: AI That Forgets
Large Language Models have revolutionized document processing. In tasks involving structured notes extraction for example, they can read a 50-page prospectus and extract dozens of data points such as coupon rates, barrier levels, underliers and maturity date in seconds and with remarkable accuracy. But there’s a fundamental problem:
Every conversation with an LLM starts from zero. The model has no memory of what it learned yesterday.
When your team encounters a new type of structured note feature, such as: “volatility threshold overlay” or “commodity hedging disruption adjustment”, the LLM can recognize it, describe it, even extract its values. But tomorrow, when you process another document with the same feature, the model doesn’t remember. It can’t tell you that this is the 47th time it’s seen this pattern, or that last month you decided to standardize how you capture it.
This is the paradox of modern AI: incredibly intelligent in the moment, but institutionally amnesiac. For financial institutions processing thousands of structured notes, this creates a painful workflow of repetitive decisions, inconsistent data capture, and manual tracking of “which features have we formalized?”
The Solution: AI + Process Automation
At Everysk, we’ve built something different: a framework where AI intelligence and process automation work together, creating a system that genuinely improves with every document it processes.
The key insight is separating what LLMs do brilliantly: understanding natural language, recognizing patterns, extracting structured data, from what they cannot do: maintain state, track frequency, update schemas, and execute auditable workflows. Our Document Extraction Framework handles both.
How It Works: The Three Principles
Before describing the core principles, some definitions: features are the individual data points and provisions we identify and extract from a document. Some are standard and expected. Others are less common or newly encountered. Everysk captures both, so nothing is lost when a document includes something your current schema does not yet cover. Promotions are the controlled workflow that turns a frequently seen, “unrecognized” feature into an official, standardized schema field. When a feature shows up often enough, Everysk surfaces it as a promotion candidate with frequency, examples, and context.
So, to formalize, our framework is built on three core principles that transform ephemeral AI insights into persistent institutional knowledge:
1. Capture Everything
Traditional extraction systems work from a fixed schema: if a field is not defined, the data is lost. Our extraction prompt instructs the LLM to capture both official schema fields and any unrecognized features it discovers. When the model encounters a novel feature, perhaps a “lookback strike setting” or “correlation coupon trigger” it captures the raw text, extracted values, and even suggests a canonical name for grouping similar features across documents.
This means no data is ever discarded. Every document teaches the system something new.
2. Normalize Consistently
Different issuers use different terminology. One prospectus calls it “estimated value,” another “fair value estimate,” a third “issuer estimated value.” Without normalization, your system sees three separate features when there’s really one.
Our FeatureNormalizer maintains a growing dictionary of aliases, mapping variations to canonical names. When the LLM extracts “synthetic dividend deduction,” the system automatically groups it with “decrement index adjustment.” This happens at ingestion time, so frequency analysis is accurate from day one.
3. Promote Deliberately
Here’s where process automation transforms AI capability into institutional knowledge. When a feature appears frequently enough, for example “estimated value range” appears in 85% of your documents, it is time to promote it from an “extension” to an official schema field.
But this isn’t automatic. Our Feature Extractor App presents analysts with promotion candidates, showing frequency counts, confidence scores, sample contexts, and the specific CUSIPs where each feature appears. Humans make the decision; automation executes it.
The Promotion Pipeline: Where AI Meets Workflow
When an analyst clicks “Promote,” three things happen atomically:
- Schema Update: The feature is added to the official schema with its canonical name, description, and data type. Version number increments automatically.
- Prompt Generation: A new extraction prompt is generated, instructing future LLM calls to extract this feature directly to its designated location and no longer as an “unrecognized” extension.
- Historical Backfill: All previously processed documents containing this feature are updated. Data migrates from extensions to the official schema location, with full audit trail.
This is the critical capability that raw LLM interactions cannot provide. The Extension Index, a pre-computed lookup structure, enables O(1) feature location across thousands of documents, making backfill operations that would take hours complete in seconds.
Why This Can’t Be Done in ChatGPT
For the simple reason that conversational AI excels at one-shot tasks: “Extract data from this PDF.” It struggles with recurrent processes that require:
- Persistent State: Tracking which features have been promoted, which documents have been processed, and what the current schema version is.
- Auditable Updates: Recording who promoted what feature, when, and why, and with the ability to roll back if needed.
- Bulk Operations: Updating 10,000 extraction records when a feature is promoted, maintaining referential integrity.
- Schema Evolution: Versioning prompts and schemas so you know exactly which model configuration produced which extraction.
- Workflow Integration: Connecting the AI’s output to downstream systems and risk engines, trading platforms, compliance databases.
An LLM in isolation is a brilliant consultant who shows up every day with no memory of previous meetings. Everysk’s framework gives that consultant a CRM, a project management system, and an institutional knowledge base.
The Virtuous Cycle: Extraction That Improves Over Time
The result is a system that genuinely learns:
Month 1: Your schema covers 60% of structured note features. The remaining 40% are captured as extensions, visible but not yet standardized.
Month 3: Analysts have promoted the 15 most common extension features. Schema coverage rises to 80%. Extraction accuracy improves because the prompt now explicitly requests these fields.
Month 6: Historical documents have been backfilled. Reports that once required manual data entry now populate automatically. The FeatureNormalizer’s alias dictionary has grown to handle 50+ naming variations.
Month 12: Your extraction schema has evolved through 20+ versions, each documented and auditable. New document types that would have required schema redesign are handled gracefully, and novel features land in extensions, get analyzed, and get promoted through the standard workflow.
Building the Future of Financial Document Intelligence
Everysk’s Feature Extraction Framework represents a new paradigm in financial AI beyond using LLMs for point-in-time intelligence, and embedding them within automation workflows that preserve and build upon their insights.
Every document your organization processes makes the system smarter. Every analyst’s decision about feature promotion becomes institutional knowledge. Every schema update improves extraction accuracy for all future documents and retroactively enriches your historical data.
This is what enterprise AI should look like: cutting-edge intelligence with enterprise-grade process automation, creating systems that work today and improve tomorrow.
