About ATLOCK

🔒System Lockdown

Lock your entire system for a set duration. No bypass. No password override during the lock period.

🛡File Guard

NTFS-level file locking. Protected files cannot be opened, moved or deleted by anyone.

🔑Password Vault

Encrypted local password storage. Your credentials stay offline — no cloud, no leaks.

📸Intruder Log

Automatically captures intruder photos on failed unlock attempts. Know who tried.

⚡Emergency Halve

One-time emergency option to halve your remaining lock time. Use it wisely.

📦Single .exe

No installation. No setup wizard. Drop the .exe and it runs. That's it.

FIELD GUIDE · ATLOCKLock your PC on a timer — full walkthrough
  1. Download the ATLOCK zip from the button above and extract it anywhere — no installer, no admin rights needed.
  2. Launch ATLOCK.exe and set your lock duration on the Lockdown panel.
  3. Confirm your master password. During the lock window there is no bypass and no override — plan accordingly.
  4. Want an escape hatch? Arm the one-time Emergency Halve before you lock, not after.
  5. Add sensitive documents to File Guard so they cannot be opened, moved or deleted while you are away.
  6. Walk away. Any failed unlock attempt is photographed automatically into your Pictures folder.

ATLOCK FAQ

What happens if a System Lockdown is running and I need my PC back early?
Lockdown timers can't be bypassed before they end — that's the whole point of it. Only the one-time Emergency Halve option can cut your remaining time in half.
Where are intruder photos and videos saved?
Straight to your own Pictures/Videos folders on your machine. Nothing is ever uploaded or sent anywhere.
Is my Password Vault actually encrypted?
Yes — the vault is AES-encrypted with a key derived from your master password, and it never leaves your device.
Do I need a webcam for ATLOCK to work?
No. Intruder capture uses a webcam if you have one, but Lockdown, File Guard and the Password Vault all work fine without it.

ANOTE

The Notepad Killer.

Premium Text Editor with real tabs, live syntax highlighting, per-file password locks, in-app translation and auto save. Everything Windows Notepad never grew into.

⬇ Download ANOTE
VERSIONCurrent public release (GitHub)
PLATFORMWindows 10 / 11, 64-bit
INSTALLNone — single portable .exe
OFFLINEYes — except the Translator feature
FILE TYPESPlain text, code, markdown
ANOTE.exe — Syntax highlighting, live.

About ANOTE

📑Multi-Tab

Work on multiple files simultaneously. Proper tabbed interface — not a workaround.

🎨Syntax Highlighting

Code-aware highlighting for multiple languages. Windows Notepad never had this.

🔐Password Lock

Lock individual files with a password. Your private notes stay private.

🌍Translator

Translate selected text in-app. No copy-pasting to browser required.

🖼Meme Canvas

Create memes directly inside your text editor. Because why not.

💾Auto Save

Never lose your work. ANOTE saves automatically so you don't have to think about it.

FIELD GUIDE · ANOTEPrivate, tabbed notes in five minutes
  1. Run ANOTE.exe and open as many files as you like — each one gets a real tab.
  2. Writing code? Syntax highlighting switches on automatically per language.
  3. Select any passage and use Translator to translate it in place (this one feature needs internet).
  4. Lock a file with its own password so only you can reopen it.
  5. Just type — Auto Save writes your work to disk as you go, so a crash never wipes it.
  6. Feeling lazy? Meme Canvas turns your text into a meme without leaving the editor.

ANOTE FAQ

Can ANOTE open large text or code files?
Yes — ANOTE handles plain text and code files comfortably, with live syntax highlighting and multiple tabs open at once.
Does the Translator feature need internet?
Yes, translation calls an online service, so it needs a connection. Every other ANOTE feature works fully offline.
What happens to my work if ANOTE closes unexpectedly?
Auto Save keeps your work saved as you type, so an unexpected close won't wipe out what you've written.
Can I password-protect individual notes?
Yes — lock any file with its own password right inside ANOTE, so only you can reopen it.

Field Guides

Practical, step-by-step walkthroughs for the tasks people actually download these apps for. Written by the developer, updated with every release.

GUIDE 01 · SECURITY · 4 MIN READHow to protect a folder so nobody can touch it (ATLOCK File Guard)
  1. Open ATLOCK and go to the File Guard panel.
  2. Add the files or folders you want protected — NTFS-level locking is applied immediately.
  3. While guarded, files cannot be opened, moved or deleted by anyone on that machine.
  4. Combine with System Lockdown when leaving your desk: guarded files stay protected even if someone sits at your unlocked session.
  5. Remove guard from the same panel whenever you need normal access again.
GUIDE 02 · PRIVACY · 3 MIN READKeep an offline encrypted password vault (ATLOCK Vault)
  1. Open the Password Vault panel in ATLOCK and set a master password.
  2. Your vault is AES-encrypted with a key derived from that master password.
  3. Add credentials as usual — everything is stored locally on your device.
  4. There is no cloud sync and no account, so nothing can leak from a server that doesn't exist.
  5. Remember: forgetting the master password means the vault stays closed. That is the point.
GUIDE 03 · PRODUCTIVITY · 3 MIN READReplace Notepad completely: tabs, highlighting and auto save (ANOTE)
  1. Set ANOTE as your default editor for .txt and code files.
  2. Open multiple files — each gets a proper tab, not a workaround window stack.
  3. Code files get language-aware syntax highlighting automatically.
  4. Auto Save runs as you type, so closing the laptop mid-sentence costs you nothing.
  5. For private journals, lock the individual file with its own password.
GUIDE 04 · MEDIA · 4 MIN READShrink and convert images for web upload without quality loss (APIC)
  1. Drag your images (or a whole folder) onto the APIC window.
  2. Choose Convert → WEBP for the best size-to-quality ratio on websites.
  3. Add the Compress operation to cut file size dramatically without visible loss.
  4. Run the batch — progress for all files is shown in one pass.
  5. Verify originals are untouched: APIC editing and conversion are non-destructive unless you choose to overwrite.

Akhouri Anmol Kumar

Founder & Developer — Akhouri Systems

Akhouri Systems is not just about a software manufacturer built by a kid. It is now about a word called EGO.

I will either make Akhouri Systems the world's biggest software manufacturer and a direct competitor of Microsoft's Windows default apps — or make this company a legend in the software field.

If I fail — which many say is the most likely outcome, especially when I stand alone with no support — I will still make sure Akhouri Systems reaches a level where Microsoft recognizes us and takes inspiration from our apps to build theirs better.

Because if they don't — maybe one Akhouri Systems failed. But another will rise.
