Claude ships long-context document sets for research and messaging work
Anthropic raised the working context for uploaded document sets and added persistent project files that stay attached across conversations.
Why it matters for you
Your positioning inputs live in fifteen places — win-loss notes, analyst briefs, pricing pages, call transcripts — and until now you could not look at them together.
- The larger working context takes the whole set at once, not a summary of a summary
- Persistent project files keep the messaging doc attached, so you stop re-pasting it into every conversation
- That changes the question you can ask from “summarise this” to “what do buyers never repeat back to us”
Try this
Upload your last ten win-loss summaries plus your current messaging doc and ask which claim buyers never repeat back to you. Cut or rewrite that claim.
Paste this into your AI tool
Here are my last ten win-loss summaries: [paste them]. Here is our current messaging doc: [paste it]. List every claim the messaging doc makes, and for each one show whether buyers repeated it back, ignored it, or contradicted it — quote the line you are drawing on. Flag the claims with no evidence either way rather than guessing why.
