How to use AiMixUp

Short, step by step guides for the things people actually ask about — building assistants, Smart Spaces, sharing chats, exporting to PDF, managing credits — followed by every frequently asked question.

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. Open 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. Choose how you want to sign up. Use email and password, or continue with Google. Both land on the same account.
  3. Confirm your email. Open the confirmation email and click the verification link. You're signed in and ready to chat.
  4. Pick 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. Open the chat list. From the home screen, tap the "+" button to open the chat composer. Or pick "New chat" from the side menu.
  2. Choose a model. Use the model selector at the top to pick OpenAI GPT, Claude (Anthropic), Gemini (Google), or Grok (xAI). You can switch models in the middle of a conversation.
  3. Type 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. Rename the chat. Tap the chat title to rename it so you can find it later in the list.

Pick the right AI model

AiMixUp gives you OpenAI GPT, Claude, Gemini, and Grok in one place. Choose by the job, and switch any time inside a chat.

  1. Open the model selector. At the top of any chat, tap the current model name to see the full list. Each model shows a short note about what it's good at.
  2. Match the model to the task. Claude is great for long form writing and careful reasoning, GPT is a strong all rounder, Gemini is cost effective for bulk work, and Grok is a strong value alternative.
  3. Switch mid conversation. You can change the model in the middle of a chat. The new model keeps the conversation so far as context, so you can start cheap and escalate only when you need to.
  4. Pick an image model for pictures. Image capable models appear in the same selector. Choose one to switch the composer into image mode.

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

Smart Spaces

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

Create a Smart Space

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

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

Add reference files to a space

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

  1. Open the space. Side menu, then "Spaces", then tap the space name.
  2. Open space settings. Tap the gear icon. You'll see a "Knowledge" or "Files" tab.
  3. Upload 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 space.
  4. Ask questions. Open any chat in the space and ask: "What does the contract say about cancellation?" The AI answers from the space's files.

Connect data sources to a space

Beyond one off file uploads, add data sources to a space so their content is scanned, indexed, and searchable for every chat inside it.

  1. Open the space, then its settings. Side menu, then "Spaces", tap the space, then the gear icon.
  2. Open the Data sources tab. Add a data source and upload or import the material you want the space to know about. Imported files are virus scanned before they're indexed.
  3. Let it index. We extract the text and make it searchable for the whole space. Larger sources take a little longer.
  4. Ask across everything. Any chat in the space can now answer from the combined files and data sources, with citations back to the source.

Generate a Wiki for a space

Every Smart Space can write its own Wiki: a living overview of the project built from its chats, files, and data sources.

  1. Open the folder Wiki. Inside a space, open the "Wiki" tab. The first time, tap "Generate" to build it.
  2. Read the overview. The Wiki summarises what the project is about and links out to the chats, files, and Kanban items it drew from.
  3. Refresh when things change. Tap "Refresh" after you add new chats or files. Generation runs in the background, so you can keep working while it rebuilds.

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. Open or create a chat. You can attach files to any chat, whether it lives in a space or not.
  2. Tap the paperclip or attach button. Pick a file from your device. We support PDF, DOCX, XLSX, TXT, MD, CSV, and most image formats.
  3. Wait for parsing. We convert the file to text inside our own infrastructure (no third party processor). It usually takes a few seconds.
  4. Ask 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 Space as a single PDF you can share or archive.

  1. Open the chat or space you want to export. From the side menu, navigate to the chat or open the Smart Space.
  2. Open the export menu. Tap the "…" menu in the top right of the chat, then "Export". For a whole space, open space settings, then "Export".
  3. Choose PDF. Select "PDF". Pick what to include: attachments, AI replies only, or the full transcript.
  4. Download 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. Open the chat. Side menu, then tap the chat you want to share.
  2. Open the share dialog. Tap the "…" menu, then "Share".
  3. Enable public link. Toggle "Anyone with the link can view" on. We generate a unique URL like https://aimixup.com/shared/<id>.
  4. Copy 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. Revoke 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. Open or start a chat. Image generation lives in the same chat as text. There's no separate screen.
  2. Switch 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. Describe 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. Send 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. Open a chat. Any chat works.
  2. Toggle the web search button. In the composer, tap the globe icon to turn on web search for your next message.
  3. Ask a question. Phrase it like a search: "What did Anthropic announce this week?" The AI fetches results, reads them, and answers with sources cited.

Edit images in the Image Studio

Image Studio is a dedicated canvas for creating and refining images, instead of doing it inline in a chat.

  1. Open Image Studio. From the side menu, open "Studio". You get a canvas with a prompt box and image tools.
  2. Generate a starting image. Describe what you want and generate. Be specific about subject, style, mood, and format.
  3. Refine with image to image. Use the generated picture as the base and ask for edits — change the background, restyle, or adjust details. The Studio keeps your previous versions.
  4. Download or reuse. Download the final image, or send it into a chat. Each generation or edit costs a small number of credits, shown before you run it.

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. Open Settings, then Billing. Tap your avatar, then "Settings", then "Billing".
  2. See your balance. Your current credit balance is at the top, with a chart of recent usage.
  3. Pick 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.

Upgrade, downgrade, or cancel your plan

Change plans or cancel any time from Billing. Paid plans refill your credits automatically each period; cancelling stops the next renewal.

  1. Open Settings, then Billing. Tap your avatar, then "Settings", then "Billing".
  2. Change your plan. Pick a higher or lower tier. Upgrades take effect immediately and are prorated; downgrades apply at the next billing period.
  3. Cancel if you need to. Choose "Manage subscription", then "Cancel". You keep access until the end of the current period, then the plan stops renewing.
  4. Resubscribe later. You can re-enable a plan any time from the same screen. Your chats and spaces stay in place while you're on the free plan.

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. Open the login screen. Go to https://aimixup.com or open the app and tap "Sign in".
  2. Tap "Forgot password?". Enter your account email.
  3. Open the reset email. Click the secure link inside. It opens a screen where you set a new password.
  4. Sign 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.

Delete your account and all data

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

  1. Email support. Send a request from your account email to support@aimixup.com with the subject "Delete my account".
  2. Confirm. We'll reply with a confirmation step so we know it's really you.
  3. Done. We permanently remove your account, chats, smart spaces, files, and billing history. This can't be undone.

Mobile app

Install the Android app and run small models on your phone.

Install AiMixUp for Android

Get the Android app from Google Play. Same account, same chats, same credits.

  1. Open Google Play. Search for "AiMixUp", or open https://aimixup.com and tap "Get the app".
  2. Install and open. Tap "Install". Open the app when it's done.
  3. Sign in. Use the same email and password (or Google) you use on the web. Your chats sync automatically.

Teams and collaboration

Share a workspace with teammates, chat in groups, and manage contacts.

Create a workspace and invite your team

A Workspace lets several people work under one shared plan and credit pool. You invite members by email and pay per seat.

  1. Open Settings, then Workspace. Tap your avatar, then "Settings", then "Workspace". Create a workspace if you don't have one yet.
  2. Invite a member. Tap "Invite member" and enter their email. They get an invitation link. Pending invites appear in the list so you can resend or cancel them.
  3. They accept and join. Once they click the link and sign in, they join your workspace and inherit its plan automatically.
  4. Manage seats and billing. Open the Billing section of the workspace to add or remove seats. Team plans are billed per seat and everyone draws from the shared credit balance. Seat changes are prorated.
  5. Remove someone. From the members list, open a member's menu and choose "Remove". They lose access to the shared workspace immediately.

Start a group chat

Create a room with several people and one or more AI assistants, or a human only chat with no assistant at all.

  1. Open the new chat wizard. Tap "+", then choose "Group chat".
  2. Add people. Pick the teammates or contacts you want in the room.
  3. Add assistants (optional). Add one or more AI assistants so they reply to the whole group. Skip this step for a human only chat.
  4. Start talking. Everyone in the room sees the conversation. Mention or prompt an assistant and it answers the group.

Add or remove a contact

Contacts are people you've connected with so you can start direct messages and add them to group chats.

  1. Open a profile or direct message. Find the person from a shared chat or by opening a direct message with them.
  2. Add contact. Tap "Add contact" to connect. They now appear in your contacts list for quick access.
  3. Remove contact. Open the contact's menu and choose "Remove contact". Your existing message history stays, but no new messages are exchanged. It does not delete their account.

Voice and video calls

Call teammates in real time, share your screen, and transcribe or record.

Start a voice or video call

Calls run in real time in the browser and the mobile app. You can switch the camera on or off and share your screen.

  1. Open a chat. Open a direct message or a group chat with the people you want to call.
  2. Start the call. Tap the call button and choose voice or video. The other participants get an incoming call ring.
  3. Share your screen (video calls). During a video call, tap "Share screen" to present. Tap it again to stop.
  4. Leave. Tap the red hang up button to leave. The call ends for everyone once the last person leaves.

Transcribe or record a call

Turn on live transcription and recording during a call. Both use AI and cost a small number of credits while active.

  1. Open the call controls. While in a call, open the controls bar at the bottom.
  2. Turn on transcription. Tap "Transcribe" to get a live speech to text transcript of the conversation as it happens.
  3. Turn on recording. Tap "Record" to capture the call. A recording indicator shows while it's running.
  4. Find it afterwards. When the call ends, the transcript and recording are saved privately to the chat so you can review or share them.

Desktop app

Install the Windows desktop app and run small models locally.

Install AiMixUp for Windows

Download the Windows desktop app and sign in with the same account. It can also run small AI models locally on your machine.

  1. Download the installer. Go to https://aimixup.com and download the Windows desktop app, or use the download link in the footer.
  2. Run the installer. Open the downloaded file and follow the prompts. If an update can't replace a file, fully close AiMixUp first and run the installer again.
  3. Sign in. Use the same email and password (or Google) you use on the web. Your chats and credits sync automatically.
  4. Run a model locally (optional). The desktop app can run small open models on your own machine for basic chat without a cloud call. Frontier models still run in the cloud.
