Now you can see what you missed easily! Game Completion %, every Shard/Fragment/Ore, costs, locations, Game Statistics, Hunter's Journal, Achievements, Game Completion essentials. And if you are completely lost, I designed a spoiler-free Hint system based on your individual game progress.
Every single penny counts: Donate any amount. By donating you directly contribute to the purpose of improving the tool for yourself and everyone else.

There is no game completion list in Hollow Knight. There is no easy way to check in-game what specific things you forgot to do or missed for full 112% Game Completion, Hunter's Journal, Achievements and many other hidden things. This Analyzer I created should help checking all of it incredibly easier for you.
Inspirations and thanks: love for Hollow Knight, discussions on the forum, KayDeeTee and bloodorca's Save Editors, programming learning, Elderbug, ManicJamie for HKTranslator, Klocus for cookiealert.
More info with features and visual previews can be found in the official Steam Guide for the Tool.
There are two ways to use this web tool:
-
Simple way: just choose your user*.dat save file and see the magic happen! See save game locations paragraph below on where to find your Hollow Knight save files.
The tool doesn't have the power to modify any of your files, but always do backups just in case. -
Advanced way: for people who wish to share saves on forums in text format through pastebin.com. Step by step tutorial:
-
Use bloodorca's amazing Online Save File Editor to decode your Hollow Knight user*.dat save file into text.
-
Left-click inside the text box in the Editor after decoding the save and press CTRL+A (or Right-click -> Select All). Only the text inside the text box (decoded save file contents) should be selected.
-
Press CTRL+C (or Right-click -> Copy) to copy the whole contents inside the text box.
-
Go to the Tool's webpage and press CTRL+V (or Right-click -> Paste) to paste the copied text inside the text box.
-
Click "Analyze Text". If the copy-pasted data was correct, you will see your Completion %, Play Time, and a whole list of things you have done (✅) or not yet done (❌).
-
If you have Steam Cloud enabled for Hollow Knight, you can download your save directly from here.
You can use this if you want to check your save progress without access to your PC (on mobile/tablet for example) or if you don't want to search manually for the save files.
%USERPROFILE%\AppData\LocalLow\Team Cherry\Hollow Knight\
Pro Tip: Copy and paste this code into the folder path bar of the Windows File Explorer window and press Enter to go there instantly (Windows 10). You can also paste it inside the Run window (Windows key + R).
Example path: C:\Users\your-username\AppData\LocalLow\Team Cherry\Hollow Knight
~/.config/unity3d/Team Cherry/Hollow Knight/
~/Library/Application Support/unity.Team Cherry.Hollow Knight/
user*.dat — main save file. Where * is a number between 1 and 4, and it is the appropriate save slot inside the game.
user*.dat.bak1 — auto-backup save file.
user*_[game-version-numbers].dat — duplicate of the main save file. Serves as a backup after any game update.
My tool uses client-side Javascript, so it runs on anything that has a modern browser. Even without internet access. You can use it locally on your PC, on mobile or on any operating system you desire (Windows, MacOS, Linux) without internet connection — everything is done on your device and your CPU. To do that, you can either download the source code directly from GitHub, go to /docs folder and launch index.html. Only contents inside the /docs folder are required for the program to run. Or go to the tool's webpage and choose Page -> Save As... like you would save a normal program.
On Android running the tool locally requires manually typing the address file:///storage/emulated/0 in your browser and from there pointing to the index.html file in the folder you saved the tool into. Then you can save it in your bookmarks for easy subsequent usage.
All feedback/problems/wrong data are appreciated. Feel free to write them in the Steam Discussion thread for the Tool or under the Steam Guide.
If you like the tool and wish it developed further with more functions and easier usage, consider supporting on PayPal. PayPal supporters with at least $1 are immortalized on the Tool's Web page.

v1.0.3 2021-02-14:
— Prototype Unrescued Grubs and Unbroken Geo Rocks lists now include number of items in the title. Additionally, number of Grubs is now shown correctly – error was due to the fact, that in 1.4.3.2 HK version the 3 Collector's Arena Grubs are treated as one by the game, instead of individually, like in 1.0.0.6. They have now one number (#32) but the rest is numbered normally from #35 until #46.

— Major New Release v1.0! Finally out of Beta/Early Access.
— I want to sincerely thank one single person (from my country - Poland) who donated a total of 70 PLN ($18.21 / €15.04) to my PayPal account since the first release of my tool in August 2020. This is currently the only person who donated anything at all since the tool's release, and I am very grateful for the support, especially in these dark times, which are hard for everyone (myself included). This update and 1.0 release is dedicated mainly to this person, as well as my awesome brother and his family for being hugely supportive. I wish to also give my thanks to all people who supported the tool in other ways: by beta-testing, giving comments, new ideas, saves, Steam Points rewards, Steam Guide likes, favourites, sharing this tool with others or giving emotional support. I hope you all will enjoy this version even more and find it much easier to use 😊
— Much easier to use: Just choose a *.dat or *.bak save file to analyze. And that's it! You don't even have to press "Analyze", because programming magic does that for you.
— Go to your Steam Cloud Storage ☁ for Hollow Knight instantly with a press of a button! It can't get any easier to get your save file than this. Steam Cloud can be also useful if you want to quickly check your in-game progress on mobile outside your PC. Saves in the Steam Cloud are updated after exiting the game.
— Optimized: Now tool is compressed, works faster and is more web- and mobile-friendly than before. At least I hope 😉
— Visual completion percentages in all sections for better readability (red = not started yet (0%), blue = partially completed, green = fully completed)
— Game Status additions:
✅ Charm Notches + visuals
✅ Shade Geo + visuals. Will appear only if the Shade is holding at least 1 Geo. If you have at least 1 Geo alongside the Shade Geo, a total amount (Geo + Shade Geo) will be displayed as well.— Game Statistics additions:
✅ Shade Geo (Amount of Geo the Shade is currently holding)
✅ Journal: Void Idol Attuned
✅ Journal: Void Idol Ascended
✅ Journal: Void Idol Radiant
✅ White Palace Secret Room visited (Unidentified secret room, help us identify this room!)— Hints/Spoilers Checkboxes now don't reset each time a save is analyzed (you don't have to click them again). Your choice is also remembered between different visits, system restarts or page reloads!
— Easy auto-copy Windows HK Save files location to clipboard. Just Left-click the text, then click Choose File/Browse..., and paste into top address bar to go to the HK Windows save file location instantly without searching!
— Improved text area focus, graphics and readability
— Increased brightness of the Steel Soul Health Masks when analyzing a Steel Soul save file
— Error messages when chosen an invalid file, or when the text inside the text area is not a valid HK save file
— Rearranged some entries and added + corrected some spoiler/location descriptions
-
2021-01-19:
