INDEPENDENT DESKTOP SOFTWARE LAB · INDIA

Every app we build starts with a problem nobody else bothered to solve.

ABOUTWho is behind Akhouri Systems?
Akhouri Systems is a desktop software company built on one idea — if existing software frustrates you, build something better. Every product in our lineup started as a personal problem. Every line of code written with one goal: zero compromise. Founded and solely developed by Akhouri Anmol Kumar — Indian Software Developer.
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)
- Open ATLOCK and go to the File Guard panel.
- Add the files or folders you want protected — NTFS-level locking is applied immediately.
- While guarded, files cannot be opened, moved or deleted by anyone on that machine.
- Combine with System Lockdown when leaving your desk: guarded files stay protected even if someone sits at your unlocked session.
- 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)
- Open the Password Vault panel in ATLOCK and set a master password.
- Your vault is AES-encrypted with a key derived from that master password.
- Add credentials as usual — everything is stored locally on your device.
- There is no cloud sync and no account, so nothing can leak from a server that doesn't exist.
- 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)
- Set ANOTE as your default editor for .txt and code files.
- Open multiple files — each gets a proper tab, not a workaround window stack.
- Code files get language-aware syntax highlighting automatically.
- Auto Save runs as you type, so closing the laptop mid-sentence costs you nothing.
- 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)
- Drag your images (or a whole folder) onto the APIC window.
- Choose Convert → WEBP for the best size-to-quality ratio on websites.
- Add the Compress operation to cut file size dramatically without visible loss.
- Run the batch — progress for all files is shown in one pass.
- Verify originals are untouched: APIC editing and conversion are non-destructive unless you choose to overwrite.
Head-to-Head vs Windows Defaults
Why replace the apps that already ship with Windows? Because "ships by default" and "good" are two different things.
| Capability | Windows default app | Akhouri Systems |
|---|---|---|
| Text editing | Notepad — plain text, no highlighting, no per-file privacy | ANOTE — real tabs, syntax highlighting, password-locked files, translator, auto save |
| Calculator | Calculator — fixed look, no customization, no video/image buttons | ACALCU — every button customizable (color/font/image/video ≤59s), scientific suite, lighter on RAM & CPU* |
| Image handling | Photos — slow for batches, limited formats, no system-wide search | APIC — batch convert/compress hundreds of images, PNG/JPG/WEBP/BMP/TIFF/ICO, image search, drag & drop |
| System lock & file protection | None built in beyond basic screen lock | ATLOCK — timed lockdown with no bypass, NTFS File Guard, intruder photos, offline AES vault |
| Data & telemetry | Cloud accounts and telemetry encouraged | All four apps — no telemetry, no accounts, no cloud. Everything stays on your machine |
| Installation | Preinstalled / Store updates | All four apps — single portable .exe, no installer, no admin rights |
*Performance claims based on developer benchmarking against the default Windows Calculator on identical hardware.

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.
