This page explains how to use Ariolu products on the web and on your devices. Ariolu LLC builds apps and browser tools for planning, practice, creativity, and short games. Use the guides below if you are installing an app for the first time, converting a file in AriStudio, or looking for account and policy information.
1. Getting started
Ariolu is a small software studio. The website is the hub for three kinds of products:
- Downloadable apps — Axolotl, Text Simplifier, Reaction Lab, and Line Ninja from the Downloads page. Text Simplifier is on Google Play and the App Store. The others also list Fire OS and desktop where available.
- Browser tools — AriStudio for image and media work, and AriArt for drawing, both run in your browser with no install.
- Games — AriPlay hosts reaction tests and arcade games in the browser, plus a separate RPG maker at rpg.ariolu.com.
If you only want to try something quickly, open AriPlay or AriStudio. Nothing is uploaded to Ariolu servers for those browser tools; conversion and drawing happen on your device. If you want daily planning, notes, goals, and health tracking, install Axolotl from the store that matches your device.
Find the right product
- Need a planner and assistant on your phone or PC? Use Axolotl.
- Want to measure reaction time or train aim? Use Reaction Lab on mobile or the reaction games on AriPlay.
- Need to rewrite, check, or create text from a paste? Use Text Simplifier.
- Want a short arcade session? Play Line Ninja or open AriPlay.
- Need to crop, convert, or retouch a file? Use AriStudio.
- Want a blank canvas with layers? Use AriArt.
2. How to use Axolotl
Axolotl is Ariolu’s main utility app. It is built for notes, goals, exercise tracking, reminders, and day planning. The same product is listed on Google Play, the Amazon Appstore, the Apple App Store, and as a desktop download.
Install
- Open ariolu.com/downloads.
- Find the Axolotl section.
- Choose Android, Fire OS, iOS, or Desktop.
- Complete the store install, or save the desktop file and run it on Windows. The desktop build is labeled Ultimate Edition and includes Ariolu features that ship with that installer.
First launch
After install, open Axolotl. Create or sign in to an account only if the screen asks you to. You can then add notes, set goals, and fill in the health or exercise areas you actually use. You do not have to complete every section on day one. Axolotl will not ask to send notifications until you set a reminder on the calendar.
Everyday use
- Use notes for short lists and longer writing you want on every device you install.
- Use goals for targets you can check off over a week or month, not only for the current day.
- Use the calendar to block time and set reminders. When you set a reminder, that is when Axolotl may ask for notification permission so it can alert you.
- Use exercise and health fields if you want a simple log. Axolotl is not a medical device and does not replace a clinician.
If a feature looks empty, open Settings in the app and confirm you are on the latest version from the same store you installed from.
3. How to use Reaction Lab
Reaction Lab is a senses and reaction tester. Use it to see how fast you tap, how quickly you respond to a visual or audio cue, and whether practice changes your scores over time.
Install
- Go to Downloads and open the Reaction Lab section.
- Install from Google Play, Amazon Appstore, or the App Store, or use the desktop download if you prefer a windowed app.
Run a test
- Open the app and pick a test type (for example a simple tap test or a wait-for-the-signal test).
- Read the on-screen instruction once. Most tests punish early taps, so wait for the cue.
- Complete the round without looking away from the screen.
- Save or note the score if you are tracking improvement. Repeat on another day rather than grinding the same minute, which mostly measures fatigue.
Browser alternatives live on AriPlay: CPS Test, Reaction Check, Aim Trainer, Shape Shift, Sound Reflex, The Grid, and Pattern Memory. Those do not require an install.
4. How to use Text Simplifier
Text Simplifier (listed on iOS as Text Simplified) rewrites and creates text from anything you paste or type. No account is required and there is no purchase. The app is free and supported by ads.
Install
- Open Downloads and find Text Simplifier.
- Install from Google Play or the App Store.
Rewrite or create text
- Paste or write your text.
- Tell the app what you want done with it.
- Tap Start.
- Copy the result, or send a follow-up to refine it.
Tools
- Simplify Text
- Identify Text
- True or False
- Resume Maker
- Message Maker
- Email Creator
- Page Writer
- Idea Maker
- Script Creator
- Coding
- Rate My Text
- Ask About Text
- Recipe Maker
- Custom, for any other need
Uses and ads
You start with a set of uses. You can watch a rewarded ad to earn more. No money is required to use the app.
What is sent
Only the text you typed is sent to a third-party source so the rewrite can run. Nothing else is sent. No personal data is collected.
5. How to use Line Ninja
Line Ninja is a short arcade game. You hold the screen to grow a line. The tip of that line has to land on the next platform. If it misses, you fall and the run ends.
Install and play
- Open Downloads and find Line Ninja.
- Install from the store for your device.
- Start a run from the main screen.
- Hold the screen to grow the line toward the next platform, then release so the tip can land. If the tip misses the platform, you fall.
- Keep landing on the next platform to continue the run. Try again after a fall and aim for a longer streak than last time.
Lightweight and uses little to no power or storage. Treat it as a warm-up or a break, or open AriPlay for a larger catalog of browser games.
6. How to use AriPlay
AriPlay is the games section of the website. Open ariolu.com/games and pick a title. Games run in the browser. A keyboard or mouse works best for most arcade titles; reaction tests work well with a mouse or trackpad.
Reaction and training games
- CPS Test — click as many times as you can in the time limit.
- Reaction Check — wait for the signal, then click. Early clicks fail the trial.
- Aim Trainer — hit targets as they appear.
- Shape Shift — find the shape that does not match the rest.
- Sound Reflex — react when you hear the beep. Use speakers or headphones and keep volume at a comfortable level.
- The Grid — tap the lit tile as soon as it appears.
- Pattern Memory — repeat a sequence that grows each round.
Arcade games
- Snake, Minesweeper, 2048, Wordle, Memory Match, Tic-Tac-Toe, Blackjack, Flappy Bird, Fruit Merge, BlockFall, and Connect Four — classic rules. Select the game, read the short prompt on the first screen, then play. Use the close or back control on the game view to return to the catalog.
Scores stay on the device unless a specific game says otherwise. Clearing site data will remove local scores.
7. How to use AriStudio
AriStudio is a browser studio at ariolu.com/studio. Files are processed in the browser. They are not uploaded to Ariolu for conversion. Close the tab if you need to discard an in-progress edit; download a copy first if you want to keep the result.
Edit Images
- Open the Edit Images tab.
- Upload a PNG, JPEG, or other common image.
- Adjust brightness, contrast, saturation, sharpness, or gamma with the sliders.
- Use draw or erase if you need to mark or remove pixels. Set brush size and color before you start.
- Undo or redo if a stroke goes wrong, then download the result.
Convert Files
- Open Convert Files and drop an image, audio, or video file.
- Pick an output format from the list for that file type. Images can go to PNG, JPEG, WebP, or BMP. Audio includes MP3, WAV, OGG, AAC, FLAC, and M4A. Video includes MP4, WebM, MOV, AVI, and MKV where the browser can encode them.
- Wait for conversion to finish, then download. Large video files take longer and depend on your computer, not a remote queue.
Crop & Resize
- Upload an image and choose resize or crop.
- For resize, set width and height. Keep aspect ratio on unless you want a stretched image.
- For crop, drag the box and handles, confirm, then download in PNG or another listed format.
Mirror & Rotate
Open the Mirror & Rotate tab, upload an image, flip or rotate it, and download. Use this when a photo is sideways or you need a mirrored reference for drawing.
8. How to use AriArt
AriArt is a drawing app at ariolu.com/art. It includes a canvas, brushes, fill, eraser, layers, reference images, and export.
Start a canvas
- Open AriArt on a desktop or laptop if you can. A mouse or tablet works better than a phone for detail work.
- Create a new canvas or open a saved artwork if the open dialog lists one.
- Pick pencil, fill, or eraser from the toolbar. Adjust size and color before drawing.
- Use layers to separate line work from color. Hide or show a layer instead of erasing everything.
- Import a reference if you want an image beside the canvas. Import a file onto the canvas if you are tracing or painting over a photo.
- Export when you are done. Save a copy you control; browser storage can be cleared.
Undo and redo follow the listed keyboard shortcuts in the app. If a shortcut conflicts with the browser, use the on-screen controls instead.
9. How to use the RPG creator
The RPG tool lives at rpg.ariolu.com and is also linked from AriPlay. It is a local party RPG you can customize: worlds, stats, combat, catalogs, and related panels.
- Open the RPG site and create or sign in if the page requires an account.
- Start a new RPG or open one you already made.
- Fill in bases, creatures, items, and rules you actually plan to use at the table. Empty sections can stay empty.
- Use play mode when the group is ready. Keep a backup of anything you care about; do not treat the editor as the only copy of a campaign.
10. Frequently asked questions
Do I need an account to use the website?
No. Downloads, AriPlay, AriStudio, AriArt, and Text Simplifier can be used without creating a web account. Some apps and the RPG site may ask you to sign in for sync or saved projects.
What does Text Simplifier send?
Only the text you typed. That text goes to a third-party source so the rewrite can run. Nothing else is sent. No personal data is collected.
Are my files uploaded when I convert or draw?
AriStudio conversions and AriArt drawing run in the browser. Files are not sent to Ariolu for those tools. If you use a cloud backup on your own device, that is separate from Ariolu.
Where do I delete an account?
Open Settings in the app or site you used and look for Delete Account. There is also a short guide at account-deletion.html. To ask for help with deletion, email ariolu@ariolu.com.
Why does a download say Ultimate Edition?
The desktop installer is marked Ultimate Edition because it bundles Ariolu desktop features in one file. Mobile store listings are the platform-specific apps (Axolotl, Text Simplifier, Reaction Lab, Line Ninja).
A page looks empty or stuck on a security check
Turn on JavaScript and cookies, then reload. The site uses a security service that can show a short check before the page loads. If it never finishes, try another browser or disable extensions that block scripts, then write to support if it still fails.
Is Ariolu a medical or school product?
No. Planning, health logs, and reaction tests are general-purpose tools. They are not medical advice, diagnosis, or accredited coursework.
