How to use AiMixUp

Short, step by step guides for the things people actually ask about: building assistants, Smart Folders, sharing chats, exporting to PDF, and managing credits.

Getting started

Sign up, find your way around, and run your first AI conversation.

Create an AiMixUp account

Sign up with email or Google in under a minute. You start on the free plan with a small credit balance. No credit card required.

  1. 1Open the sign up screen. Go to https://aimixup.com and click "Get started" in the top right. Or open the AiMixUp Android app and tap "Create account".
  2. 2Choose how you want to sign up. Use email and password, or continue with Google. Both land on the same account.
  3. 3Confirm your email. Open the confirmation email and click the verification link. You're signed in and ready to chat.
  4. 4Pick a plan later. You start on the free plan. You can upgrade or top up credits any time from Settings, then Billing.

Start your first chat

Open the chat list and send a message to any AI model in seconds.

  1. 1Open the chat list. From the home screen, tap the "+" button to open the chat composer. Or pick "New chat" from the side menu.
  2. 2Choose a model. Use the model selector at the top to pick OpenAI GPT, Claude (Anthropic), Gemini (Google), Grok (xAI), or DeepSeek. You can switch models in the middle of a conversation.
  3. 3Type your prompt and send. Type a question or instruction and hit "Send". The reply streams in token by token. You can stop it any time and ask a follow up.
  4. 4Rename the chat. Tap the chat title to rename it so you can find it later in the list.
Assistants (custom agents)

Build reusable assistants with their own instructions, model, and personality.

Create a custom assistant

An assistant is a saved persona with a name, a system prompt, and a default model. Open it in any chat and the persona is applied for you.

  1. 1Open the Assistants section. From the side menu, tap "Assistants", then "Create new".
  2. 2Give it a name and an avatar. Pick a short, clear name like "PDF summariser", "SQL helper", or "Marketing copywriter". Upload an avatar if you want.
  3. 3Write the system prompt. This is the instruction the AI follows every time you chat with this assistant. Be specific. Describe the persona, the tone, the kind of answers you want, and any rules it should obey.
  4. 4Pick a default model. Choose the model that fits the job. Claude is great for long form writing, GPT for general tasks, Gemini for cheap bulk work. You can override the model later in any chat.
  5. 5Save and use it. Save the assistant. From the chat composer, pick this assistant and start chatting. The system prompt is applied automatically.

Find a ready made assistant in the marketplace

Browse community assistants instead of writing your own.

  1. 1Open the Marketplace. Side menu, then "Assistants", then "Marketplace".
  2. 2Search by topic or model. Filter by category (writing, coding, marketing, research, fun) or by model.
  3. 3Try it. Tap an assistant card, then "Use". A new chat opens with that assistant's system prompt already applied.
  4. 4Fork it. Want to tweak the prompt? Tap "Duplicate". You get your own copy you can edit freely.
Smart Folders

Group chats by project so the AI keeps context across all conversations.

Create a Smart Folder

A Smart Folder is project level memory. Every chat inside the folder shares the same long term context.

  1. 1Open the Folders panel. Side menu, then "Folders", then "New folder".
  2. 2Name the folder. Pick a project style name like "Q1 Marketing Plan", "Tax 2025", or "Master thesis".
  3. 3Add a folder level instruction (optional). You can add a description or a system prompt that applies to every chat inside the folder. Useful for project rules, terminology, or reading material.
  4. 4Create chats inside the folder. Open the folder and tap "New chat". Anything you discuss is added to the folder context, so the AI remembers earlier conversations.
  5. 5Move existing chats in. From any chat's "…" menu, choose "Move to folder" and pick the folder.

Add reference files to a folder

Attach PDFs, DOCX, or notes once at the folder level. Every chat in the folder can answer with that context.

  1. 1Open the folder. Side menu, then "Folders", then tap the folder name.
  2. 2Open folder settings. Tap the gear icon. You'll see a "Knowledge" or "Files" tab.
  3. 3Upload files. Drag in PDFs, DOCX, XLSX, or plain text. We parse them inside our own infrastructure (no third party file processor) and store them as searchable context for every chat in this folder.
  4. 4Ask questions. Open any chat in the folder and ask: "What does the contract say about cancellation?" The AI answers from the folder's files.
Files and document analysis

Send PDFs, Word docs, and spreadsheets straight into a chat.

Upload a file into a chat

Attach a PDF, DOCX, or XLSX and ask the AI to summarise, extract data, or answer questions.

  1. 1Open or create a chat. You can attach files to any chat, whether it lives in a folder or not.
  2. 2Tap the paperclip or attach button. Pick a file from your device. We support PDF, DOCX, XLSX, TXT, MD, CSV, and most image formats.
  3. 3Wait for parsing. We convert the file to text inside our own infrastructure (no third party processor). It usually takes a few seconds.
  4. 4Ask the AI. Try "Summarise the main argument." "Extract every contact email." "What's the total revenue in Q3?" The AI uses the parsed text to answer.

Export a chat or project to PDF

Save a chat or a whole Smart Folder as a single PDF you can share or archive.

  1. 1Open the chat or folder you want to export. From the side menu, navigate to the chat or open the Smart Folder.
  2. 2Open the export menu. Tap the "…" menu in the top right of the chat, then "Export". For a whole folder, open folder settings, then "Export".
  3. 3Choose PDF. Select "PDF". Pick what to include: attachments, AI replies only, or the full transcript.
  4. 4Download or share. The PDF is generated on the server. When it's ready, tap "Download" or use "Share link" to send a private link.
Sharing

Share a chat with someone outside your account, read only.

Share a chat with a public link

Generate a read only public link to a chat. The person you send it to doesn't need an AiMixUp account.

  1. 1Open the chat. Side menu, then tap the chat you want to share.
  2. 2Open the share dialog. Tap the "…" menu, then "Share".
  3. 3Enable public link. Toggle "Anyone with the link can view" on. We generate a unique URL like https://aimixup.com/shared/<id>.
  4. 4Copy and send the link. Tap "Copy link" and send it via email, Slack, or wherever. The recipient sees the chat in read only mode.
  5. 5Revoke when done. Open the share dialog again and toggle it off. The link stops working immediately.
Images and creative tools

Generate and edit images, and do quick web research from a chat.

Generate an image

Use DALL·E or GPT-Image inside a chat to create an image from a prompt.

  1. 1Open or start a chat. Image generation lives in the same chat as text. There's no separate screen.
  2. 2Switch to an image model. From the model selector, pick an image capable model like DALL·E or GPT-Image. The composer switches to image mode.
  3. 3Describe the image. Be specific about subject, style, mood, and format. For example: "A flat illustration of a fox reading a book, pastel colours, white background, square."
  4. 4Send and download. The image appears in the chat. Tap to enlarge, download, or share. Each generation costs a small number of credits. The composer shows the price tag.

Ask the AI to search the web

Turn on web search so the AI can pull live facts and links into its answer.

  1. 1Open a chat. Any chat works.
  2. 2Toggle the web search button. In the composer, tap the globe icon to turn on web search for your next message.
  3. 3Ask a question. Phrase it like a search: "What did Anthropic announce this week?" The AI fetches results, reads them, and answers with sources cited.
Billing and credits

Plans, credit balance, top ups, and refunds.

Check your credit balance and top up

Credits are the in app currency. Each AI request costs a small number of credits, depending on the model and the length of the answer.

  1. 1Open Settings, then Billing. Tap your avatar, then "Settings", then "Billing".
  2. 2See your balance. Your current credit balance is at the top, with a chart of recent usage.
  3. 3Pick a plan or top up. If you're on a paid plan you can top up extra credits any time. Free users start with a starter balance and can upgrade from this screen.
Account and security

Password reset, account deletion, and privacy basics.

Reset a forgotten password

You reset, you don't recover. We never store passwords in plain text.

  1. 1Open the login screen. Go to https://aimixup.com or open the app and tap "Sign in".
  2. 2Tap "Forgot password?". Enter your account email.
  3. 3Open the reset email. Click the secure link inside. It opens a screen where you set a new password.
  4. 4Sign in with the new password. You're back in. Old sessions on other devices stay valid until you log them out from Settings, then Sessions.

Email support and we'll permanently delete your account, chats, files, and transactions.

  1. 1Email support. Send a request from your account email to support@aimixup.com with the subject "Delete my account".
