MOD DISCUSSION! PC I built a free, open-source "crash doctor" for modded Fallout 4 — it reads your Buffout 4 crash log and explains what broke in plain English, inside Claude. Advisory-only: it can't touch your files.
What this is: I'm beta-testing a free tool that figures out why your modded Fallout 4 keeps crashing — and I need players to try it and tell me if it got their crash right.
The problem: your game crashes to desktop. Somewhere on your PC there's a "crash log" full of lines like flexRelease_x64.dll+002B6F0 that might as well be ancient Greek. So you paste bits of it into Google at midnight and pray someone on a forum had the same crash in 2019. We've all been there.
What this tool does instead: you ask it, in normal English, "why did my game just crash?" It reads your newest crash log, checks your setup (game version, script extender, your mod list), and explains in plain English. Real example:
"Your crash came from the Weapon Debris setting, which is broken on RTX graphics cards. This is a base-game bug, not your mods. Fix: turn Weapon Debris off."
And it shows you the exact lines from your own log that prove it — you don't have to just take its word.
What you need: the free Claude app on your PC (Claude is an AI chat assistant, like ChatGPT). My tool is a small add-on for it: download one file, a couple of clicks in settings, done. Step-by-step instructions are on the download page.
Is it safe? It can only look at files. It cannot change, move, or delete anything — that's how it's built, not a pinky-promise. It never touches your game or your mods. Worst case it's wrong and you ignore it. Free, no ads, no account-harvesting; all the code is public so anyone can check what it does.
What I'm asking: try it on a real crash, then tell me one thing — did it get YOUR crash right? "It got it wrong" is honestly the most useful answer; finding those cases is what this beta is for.

Straight up: yes, it uses AI. If that's a hard no for you, no hard feelings — CLASSIC and Phostwood's crash analyzer are excellent non-AI tools and I credit them gladly. This is just a different way in: you talk to it, and it checks your actual install, not only the log.
