DeepMask lives at chat.deepmask.io — a unified AI workspace where you can access 25+ leading models, run web searches, visualize data, and organize work into persistent Projects. This quickstart guide takes you from a blank browser tab to your first productive AI conversation, and introduces Projects so you can see how DeepMask scales beyond one-off chats.
1

Create your account

Go to deepmask.io and sign up for an account. You can register as an individual or as part of an enterprise organization.
If your organization already has a DeepMask enterprise account, ask your administrator to invite you directly. You will receive an email with a link to join your team’s workspace.
Once registered, you will be taken to the main chat interface at chat.deepmask.io.
2

Select a model

At the top of the chat interface, open the model selector and choose the AI model you want to use. DeepMask offers 25+ models from providers including OpenAI (GPT-4o, GPT-5.2, GPT-4.1), Anthropic (Claude Opus, Sonnet, Haiku), Google (Gemini 2.0 Flash, Gemini 2.5 Flash), Mistral, DeepSeek, Grok, Kimi K2, Qwen, Gemma, and more.
Not sure which model to pick? See the model guide for a breakdown of each model’s strengths — from long-document reasoning to fast coding assistance. EU-hosted variants of select models (marked with “StackIT” or “DeepMask”) keep your data within European infrastructure.

Start a conversation

Type your first message in the chat input and press Enter. DeepMask sends your prompt to the selected model and streams the response back in real time.You can enhance any conversation with additional capabilities available from the toolbar below the input:
  • Web Search — enable Perplexity-powered search to ground responses in real-time, cited web results
  • Extended thinking — activate deeper reasoning for complex, multi-step problems
  • Response style — switch between Normal, Concise, Explanatory, Learning, or Formal output styles
  • MCP connectors — attach connected tools like Google Drive or Salesforce to give the model access to your data
A typical first conversation might look like this: you upload a spreadsheet, ask the model to analyze trends and generate a chart, then follow up by asking for a summary in a formal tone — all without leaving the chat window.
4

Switch models mid-conversation (optional)

If you want a different perspective or need a model better suited to a follow-up task, change the model at any time during a conversation. DeepMask preserves the conversation context so the new model has full awareness of what was discussed.For example, you might start with Gemini 2.5 Flash for a quick answer, then switch to Claude Opus for a more in-depth analysis of the same topic.
5

Create a Project (optional)

For ongoing work — a research initiative, a product launch campaign, or an engineering sprint — create a Project to give your conversations a persistent home.To create a Project:
  1. Click Projects in the left sidebar.
  2. Select New Project.
  3. Give the project a name and write a set of custom instructions to prime every conversation in that project (for example, “You are analyzing our Q3 operations data. Always respond in a formal tone.”).
  4. Upload relevant files — documents, spreadsheets, briefs — so every conversation in the project has access to them.
  5. Invite teammates to collaborate in the same project workspace.
Projects persist across sessions. Every conversation you start inside a project inherits the project’s instructions, files, and shared context automatically.
