AI systems can only work with information you feed them, and VA documents are interconnected—medical records inform disability ratings, which affect benefit eligibility. Uploading multiple documents at once lets the AI see the full picture of your case rather than isolated fragments, catching connections and inconsistencies that might otherwise slip through.
Think of a context window like a blackboard. Some AI tools have a small blackboard—they can only keep a few things written down at once. Other tools have a huge whiteboard—they can track a lot of information simultaneously. This matters for VA work because you often need to reference multiple documents at the same time.
A context window is the amount of text an AI tool can "see" and work with in one conversation. If you have a 100-page VA file and a tool has a small context window, the AI might not be able to read the whole thing or connect information across different documents.
Let's say you're building an appeal and you need the AI to reference three things: (1) Your original VA decision letter, (2) Your medical records from your civilian doctor, (3) A research paper on service-connected conditions like yours. A tool with a large context window can see all three and help you connect them. A tool with a small window might only see one or two.
You might upload a document and ask the AI a question, but if that document is longer than the context window, the AI pretends to read it while actually missing chunks. This leads to incomplete answers.
For VA work, you want a tool with a big context window. Claude and Gemini are better than older versions. This lets you upload an entire case file and ask the AI to track information across all of it.
If your tool struggles with large files, break them into smaller chunks. Ask the AI to summarize document one, then document two, then tell it to compare them.
Try this: Before uploading your VA documents, check which AI tool you're using and its context window size. If it's over 100,000 tokens, you're good. If it's smaller, break your documents into two uploads instead of one. The AI will work better with manageable chunks.
