Fix it with Stella

Whatever broke, tell Stella.

Stella is a desktop AI agent that can actually use your computer — apps, browser, files. Pick your problem below, or just download it and describe what's wrong in your own words.

Free. No credit card, no trial. Go is $5/mo, Pro is $15/mo.

ComfyUI broke again. Stella fixes it.

ComfyUI won't start, custom nodes failing to import, torch/CUDA mismatch, xformers errors — Stella reads the actual error and repairs your setup without a reinstall.

Those “virus” pop-ups? Not a virus. Gone.

Fake 'your PC is infected' pop-ups are browser notifications, not a virus. Stella opens your browser settings, revokes every rogue site's permission, and blocks new ones.

C: drive full? Don't guess what to delete.

Disk full and can't install updates? Stella scans what's taking up space, explains what's safe to delete and why, and cleans up only what you approve. No cleaner-app roulette.

Thirty spreadsheets, one clean sheet.

Merge a folder of Excel and CSV files into one clean spreadsheet — columns aligned, rows deduped — without learning Power Query. Tell Stella what the final sheet should look like.

Bank statement PDFs, typed for you.

Stop retyping bank statements. Drop the PDFs on Stella — every transaction extracted, categorized, and filed into a clean spreadsheet. Statements never leave your computer.

Stop copy-pasting web pages into Excel.

Describe the pages and the columns you want. Stella opens them in your browser, walks every page of results, and hands you a clean, deduped spreadsheet with real numbers.

Sims patch broke your mods. Again.

Sims 4 not loading after a patch? Stella checks which mods actually broke, cross-references the community lists, pulls updates, and gets your game loading — without nuking your Mods folder.

Modpack crashes on launch? The log knows why.

Instant crash is almost always the wrong Java, RAM allocation, or one bad mod. Stella reads the crash report, installs the right Java, sets the RAM, and pulls the conflicting mod.

OBS showing a black screen? Your scenes are fine.

OBS display capture black after an update? Stella reads the OBS log, switches the capture method or GPU flag, re-grants permissions, and confirms capture works — scenes intact.

Half your plugins vanished? They're still there.

FL Studio, Ableton, or Reaper lost your plugins? It's almost always a search-path or scan problem. Stella fixes the VST paths, quarantines the crasher, and rebuilds your plugin database.

Game update killed your mods. Rebuild in minutes.

BG3, Cyberpunk, Stardew — every patch breaks mods. Stella updates your mod manager, pulls current mod versions from Nexus, clears orphaned files, rebuilds the load order, and relaunches.

OneDrive hijacked your Desktop? Get your files back.

Desktop files disappeared into OneDrive? Stella untangles the folder redirection, restores real local copies, and turns off the backup switch that caused it — without losing anything.

4,000 files in Downloads? Sorted. Plan first.

Stella reads what's in the swamp, shows you a plan — where every file will go — then sorts thousands of files into clean folders in one undoable pass. Nothing deleted without approval.

Plex grabbing the wrong poster? It's the filenames.

Wrong posters and missing episodes are almost always naming. Stella renames your whole library to Plex/Jellyfin's exact convention, tags IMDb IDs, and triggers a rescan.

Car won't read the USB? It's the stick, not the radio.

Car stereo says no supported files? Stella reformats the drive the way head units expect, converts the files your radio rejects, fixes tags, and folders albums so they play in order.

“externally-managed-environment”? Just run the script.

pip refusing to install, conda vs pip conflicts, 'No module named' after installing — Stella sets up the right virtual environment, installs what your script needs, and runs it.

“VCRUNTIME140.dll is missing”? Skip the sketchy sites.

Game won't launch with a missing DLL error? Stella reads the exact error, installs the right Microsoft Visual C++ and DirectX runtimes, repairs system files, and relaunches your game.

“Path too long.” Deleted anyway.

Windows won't delete, move, or rename it because the path is too long or the file is locked. Stella uses the IT-pro tricks — long-path mode, robocopy, ownership — safely, for you.

Wrecked your git repo? Your work is still in there.

Wrong branch, hard reset, detached HEAD, merge conflict soup — git almost never loses work. Stella reads your repo's real state, finds the safe recovery path, and runs it for you.

Music library a mess? Every tag. Every cover.

Stella fingerprints every track, pulls correct titles, albums, and artwork from MusicBrainz, and files everything into clean Artist/Album folders — thousands of songs in one pass.

Start menu dead after an update? No reset required.

Start button dead, can't type in search? Stella restarts the right services, re-registers the Start/Search packages, repairs system files, and confirms it works — no factory reset.

Every attachment, out of the inbox at once.

Gmail only saves attachments one email at a time. Stella works in your own logged-in inbox, downloads every matching PDF, receipt, and photo, and files them by sender and month.

“This file can't be played”? It will be.

'This file cannot be played'? Stella reads what's in the file, converts exactly the codec your TV or phone rejects, and hands back an MP4 that just plays — one file or a whole folder.

Containers won't come up? Logs read. Stack green.

Permission-denied volumes, port already allocated, restart loops — Stella reads your compose file and container logs, fixes the ownership, port, or YAML, and brings the stack up.

Creative Cloud stuck on white? No reinstall marathon.

Creative Cloud won't open, white screen, sign-in loop, Photoshop in trial mode? Stella does Adobe's own documented fix for you — cache clear, Cleaner Tool, clean reinstall.

Photoshop says the scratch disk is full? Make room without guessing.

Stella finds what filled Photoshop's scratch disk, clears safe temporary files, selects usable storage, and relaunches Photoshop to verify the error is gone.

Windows can't hear your microphone? Find the setting that broke.

Stella checks Windows microphone permissions, the selected input, levels, services, and drivers, then records a test to verify your mic works in the app you use.

Steam says “Launching” — then nothing? Read the failure. Start the game.

Stella reads the game and Windows logs, verifies files, repairs runtimes and launch settings, disables the conflicting overlay, and relaunches to confirm it starts.
