This glossary defines the core terminology used throughout ZeroTwo and its documentation. Terms are listed alphabetically.
An in-chat tool that enables autonomous multi-step actions across your connected apps. When Agent Mode is active (via the Agent pill in the prompt bar), ZeroTwo can execute a sequence of actions — like reading a file, creating a document, sending an email, or updating a database entry — without requiring you to manually direct each step.Agent Mode uses your connected app permissions (Connectors) to perform actions. Each action is logged in the Agent Activity sidebar so you can review what was done.Related: Agent Mode documentation
A document editor embedded directly in the ZeroTwo chat interface. When Canvas Mode is active, AI responses can appear in a rich editor panel alongside the chat, rather than as plain text in the chat thread.Canvas Mode supports 7 editor types:
  1. Rich text (prose, formatted documents)
  2. Code (syntax-highlighted, language-specific)
  3. Mermaid (diagrams: flowcharts, sequence diagrams, ER diagrams)
  4. Spreadsheet
  5. HTML preview
  6. Markdown
  7. Math (LaTeX)
Canvases can be edited directly, shared via link, and exported (PDF, DOCX, Markdown).Related: Canvas Mode documentation
An OAuth-based integration that links ZeroTwo to an external app or data source. Connectors allow ZeroTwo to read from, write to, and take actions within connected apps.ZeroTwo supports 45+ connectors, including:
  • Google Drive, Gmail, Google Calendar, Google Contacts
  • Notion, GitHub, Linear, Box, Dropbox, Canva
  • Supabase, and many more
Connectors are authorized via standard OAuth flows (you’re redirected to the app to grant permission). You can manage connectors in Settings → Connectors.Related: Connectors overview
A saved, reusable AI agent configuration built at /agents. Custom agents let you define a specific AI persona, set of instructions, tool access, and connected app permissions that persist across sessions.Custom agents are useful for recurring workflows — e.g., a “Research Agent” that always searches the web and produces structured reports, or a “Code Review Agent” with access to GitHub.Related: Custom Agents documentation
A persistent system prompt applied to all new chats automatically. Custom instructions let you define how ZeroTwo should behave, what context it should always have, or how it should format responses — without needing to repeat yourself in every chat.Set custom instructions in Settings → Personalization → Custom Instructions.Custom instructions differ from project instructions, which apply only within a specific project.Related: Custom Instructions documentation
A multi-step research engine that produces comprehensive, cited research reports on a topic. Unlike a single web search, Deep Research:
  1. Plans a research strategy (identifying sub-questions and angles)
  2. Performs multiple web crawls using Firecrawl
  3. Synthesizes findings across sources
  4. Produces a structured Canvas document with citations
Deep Research reports are longer and more thorough than standard chat responses with web search. They open automatically in Canvas Mode.Free plan: 1 deep research per day. Paid plans: higher or unlimited.Related: Deep Research documentation
Auto-learned facts and preferences that ZeroTwo stores about you, derived from your conversations. Memories allow ZeroTwo to personalize responses over time — for example, remembering your preferred coding language, your name, or your area of expertise.Memories are:
  • Stored per-account (not per-chat or per-project)
  • Viewable and deletable from Settings → Memory
  • Limited to 5 memories on the Free plan; higher on paid plans

The interface for selecting an AI model in the chat prompt bar. The Model Picker is accessible via a dropdown in the bottom-left of the chat input area. It shows all available models organized by provider, with indicators for premium vs. standard status.You can switch models mid-conversation — each message can use a different model if desired.Related: Model Picker documentation
A rate-limited AI model that counts against your monthly premium message quota. Premium models are typically the most capable frontier models from each provider.Premium models include:
  • Claude Opus, Claude Sonnet variants (Anthropic)
  • GPT-5, GPT-4o (OpenAI)
  • Gemini 2.5 Pro, Gemini 3.1 Pro (Google)
  • Grok-4 (xAI)
  • Command A, Command R+ (Cohere)
  • Mistral Large, Magistral (Mistral)
  • Qwen Max (Alibaba)
  • Sonar Pro (Perplexity)
Premium models require a Pro plan or above for access.Related: Premium vs. Standard Models
An organizational container for related chats, files, and instructions. Projects let you keep different workflows separate — for example, one project for a client engagement, one for personal research, and one for coding work.Each project can have:
  • Its own set of uploaded files (accessible in all chats within the project)
  • Project-specific custom instructions
  • A collection of related chat threads
Free plan: 1 project. Paid plans: unlimited projects.Related: Projects documentation
A lightweight, reusable AI tool that can be invoked in any chat using @skill-name. Skills are purpose-built AI tools for specific tasks — similar to functions or plugins — that you can call on demand.Skills can be built and customized at /agents and may include custom logic, specific model configurations, or tool permissions.Related: Skills documentation
A non-rate-limited AI model that has no monthly cap. Standard models are available on all plans (including Free) and do not consume your premium message quota.Standard models include:
  • GPT-5-mini (OpenAI)
  • GPT-4o-mini (OpenAI)
  • Gemini Flash Lite (Google)
  • Mistral Small (Mistral)
  • Grok 4 Fast (xAI)
Standard models are still capable and suitable for the vast majority of tasks. Premium models offer additional capability for highly complex reasoning, longer contexts, or specialized domains.Related: Premium vs. Standard Models
Dedicated creative generation pages at /studio/* for generating media beyond text:
  • /studio/images — text-to-image generation
  • /studio/video — text-to-video generation
  • /studio/audio — text-to-audio/speech generation
Studio pages offer specialized interfaces for creative generation, with model selection, parameters, and a gallery of generated outputs.Related: Studio documentation
A scheduled AI job that runs automatically at a set time, without you being present. Tasks allow you to automate recurring AI workflows — for example, a daily morning briefing, a weekly report generation, or an automated data-processing pipeline.Tasks are configured and managed at /tasks.Related: Tasks documentation
A toggle button in the chat prompt bar for activating specific tools before sending a message. Tool pills appear as small labeled buttons at the bottom of the chat input area.Available tool pills:
  • Search — enables web search with the message
  • Deep Research — triggers a multi-step research report
  • Canvas — outputs the response in the Canvas editor
  • Agent — activates Agent Mode for autonomous multi-step actions
  • Voice — starts a voice chat session
Pills are activated by clicking them (they highlight when active). Multiple pills can be active simultaneously.
Server-side technology that automatically detects when the user has finished speaking during a voice session, so ZeroTwo knows when to start processing and generating a response.VAD eliminates the need to press a “stop talking” button — you simply pause, and ZeroTwo detects the end of your speech after a brief moment of silence (typically 1–2 seconds).If ZeroTwo seems unresponsive after you speak, wait 2–3 seconds for the VAD to register the end of your speech before assuming there’s an issue.Related: Voice Issues
The Business plan’s shared organizational environment with admin panel access. A workspace includes:
  • A shared namespace for all Business plan members
  • Admin panel at /admin/* for managing members, billing, and settings
  • Member roles (Owner, Admin, Member)
  • Shared connectors and org-level settings
Individual plans (Free, Pro, Pro 2x, Plus Ultra) do not have a workspace — they’re single-user accounts.Related: Business Workspace documentation
