Get started in one minute
Pay for a plan, get your private access key and open the app.
- Choose a plan on the home page and pay with bKash, Nagad, a card or bank transfer.
- Your access key (it starts with ALLAI-) appears on screen and arrives by email.
- Open the app, paste the key and tap Continue. That's your login on this device.
- Tap your name at the bottom of the menu for Settings, credits and help.
Keep your key private. Anyone with the key can use your credits.
Open the appHow credits work
Every message uses credits from your prepaid balance.
- A message on a budget (1x) model uses 1 credit; stronger models use 2, 4 or 8.
- Web Search and each attached file add 1 credit to that message.
- Your plan's monthly credits are used first, then any credit pack you bought.
- See every credit used, refunded and added in Settings, Credits usage.
If a model fails before answering, the credits are given back automatically.
See my creditsAuto Mode
Not sure which model to pick? Let Auto decide.
- Leave the model button on Auto.
- Simple questions go to a fast, low-cost model; hard ones to a stronger model.
- The answer shows which model replied, so you can pick it yourself next time.
Auto never chooses the most expensive models, so it saves credits.
Compare answers
Ask several models the same question and get one consensus answer.
- Tap + in the chat box and choose Compare, or the Compare chip.
- Pick 2 to 5 models. Set favourites in Settings, AI Preferences.
- Read each answer side by side, then the merged consensus at the top.
Compare is great for exam answers, health and money questions where a second opinion helps.
Deep Research
Get a full report with sources for a big question.
- Open Deep Research and type your question in detail.
- Choose Standard or Deep. The AI splits the question and searches the web for each part.
- Copy the report, download it, print it as PDF, or find it later in your Library.
Add your country, budget or level to the question for a more useful report.
Projects
Keep chats, files and instructions for one goal together.
- Open Projects and tap Create a project.
- Add instructions once, for example "I am an HSC science student, keep answers short".
- Upload notes or PDFs. Every chat inside the project uses them as context.
Turn on account memory in a project so it also knows the facts you saved in Settings, Memory.
Experts and Legends
Chat with a specialist or learn from history's great minds.
- Open Experts and pick a subject expert such as BCS, IELTS or Freelancing.
- Legends are AI simulations of famous people, based on their known life and works. They are not the real people.
- Create your own expert with custom instructions under My Experts.
An expert stays on for that chat. Remove it with the × on the expert pill above the chat box.

- Image Studio: describe the picture or start from a template, then download it.

Everything you create is saved in your Library on this device.
