The User Interface

Trevor AI's user interface consists of 4 main components: the Header Menu, the Task Hub, the Calendar Timeline, and the AI Chat Assistant. On desktop, the first three are visible at once, with the AI Chat accessible via a floating button on all screen sizes. On mobile, you switch between the other panels using a bottom navigation bar.

The Header Menu

The header menu on top of the app UI contains:

1. Trevor's Logo, on the left, as the home button.
2. The currently visible calendar date, in the center, which opens the date picker when tapped.
3. Filters for the calendar view, on the right, such as Daily, 3 Days, Weekly and Monthly. Additional views can be enabled in Calendar Options.
4. The main menu at the far right, illustrated by an icon of a meditating human, containing links to My Progress dashboard, Account Settings, Calendar Options, Pro Plan details, What's New, How-to Guide, Privacy Policy, Terms of Service, Cookie Policy and Logout button.

You can configure defaults like your preferred calendar view and week start day in Settings.

The Task Hub

The Task Hub (previously known as the "inbox") displays your tasks, organised by lists. It's located on the left side of the UI (below the header menu) on larger screens, or can be opened via a button on mobile.

By default, under each list the top 3 tasks are visible. Each list title can be clicked to expand it and show all of its visible tasks, as well as the list's note.

Drag and Drop

Tasks can be dragged from the Task Hub into the calendar to schedule them. Once scheduled, tasks and events on the calendar can be dragged to a different time or day, and resized to change their duration.

Add New Task Panel

The Add New Task Panel is used to create tasks:

• Type a title for a task to create it.
• Assign the task to a list other than the default / starred list, by either clicking the hashtag '#' button or typing '#' in the title field — this opens a list picker where you can select the target list.
• Define a date and/or time using natural language, to create a new scheduled task.

Control Panel

The Control Panel at the top of the Task Hub contains the following options:

• A lists dropdown to expand a selected list, similar to clicking the list's title.
• A search field for tasks.
• 'Show Scheduled' and 'Show Completed' filters, which make scheduled and/or completed tasks visible in the Task Hub, illustrated by icons.
• 'Show Overdue' filter, which only shows scheduled tasks which are overdue and have not been marked as completed.
• A button to go to list management mode for adding and editing lists.

Task Properties

Each task in the Task Hub contains:

Scheduling Options

Tapping the scheduling icon on a task reveals:

• Add to Scheduling Queue — adds the task to Trevor's AI scheduling queue so it appears as a suggestion in the timeline at its predicted time slot. Tasks with a due date are added automatically.
• Set due date — opens a date picker to set or change the task's due date. When a due date is set you can also configure a Not Earlier Than window to control how far in advance the task can be scheduled.
• Repeat dropdown — sets recurrence rules for the task (only available for tasks created in Trevor).
• Quick and Smart scheduling suggestions — a grid of buttons showing optimal times to schedule the task based on your availability and a prediction algorithm. Up to 4 suggestions are generated across a 7-day window, scored and ranked by fit.
• Once expanded, the scheduling suggestions are also visualised in the calendar as Suggestion Events.
• For already-scheduled tasks, the panel instead shows Show in Schedule, Unfinished (returns the task for rescheduling while keeping the calendar event), and Unschedule (removes the calendar event but keeps the task in your Task Hub) options. To remove a scheduled task from the calendar without deleting it, always use Unschedule — the Remove action in the event menu permanently deletes both the task and its event.

Tip: Long-hovering (desktop) over the scheduling icon shows a quick single suggestion on the calendar. Long-pressing the icon instantly schedules the task at the top suggested time.

The Calendar Timeline

The Calendar Timeline is displayed on the right side of the UI (below the header menu), showing both scheduled tasks and calendar events.

• Calendar events and scheduled tasks are synced with your connected calendar — Google Calendar, Microsoft Calendar (Outlook & Office 365), Apple iCloud, or CalDAV. See Integrations for setup details.
• All events can be moved, resized and edited, similar to traditional calendar apps.

Event Menu

Events and scheduled tasks can be clicked on, which displays an Event Menu that includes all the actions for scheduled tasks listed above.

Plan My Day Widget

Located in the top-left corner of the calendar, the Plan My Day widget generates AI-powered scheduling suggestions for multiple unscheduled tasks at once. Clicking the button opens a panel where you can configure:

• Task source — choose which tasks to plan from: the Scheduling Queue, the Task Hub (AI-selected best tasks), overdue tasks, or the currently opened list.
• Scope — how far ahead to plan: today, 3 days, 4 days, or the full week.
• Planning strategy — Adaptive uses machine learning to score time slots based on your historical patterns (preferred times, days, and task durations), while Simple (Sequential) fills available slots in order of priority and due date.

Once generated, suggestions appear as semi-transparent overlay events on the calendar. You can then review them and either accept all in bulk or discard to start over. Overdue tasks get a dedicated mode with options to reschedule, mark as completed, or unschedule.

For more on how suggestions and auto-scheduling work, see the AI Features section.

The AI Chat Assistant

Trevor includes a built-in agentic AI assistant — accessible via the floating chat button in the bottom-right corner of the app. It's not just a help bot: the AI Chat can read your data, take actions, and handle multi-step requests on your behalf.

Anything you can do through the Task Hub or Calendar, you can also do by typing a natural language command in the chat. For example:

• Create and schedule tasks: "Add a 2-hour task called Budget Review to my Work list, scheduled for tomorrow at 10am"
• Manage your calendar: "Move my 3pm meeting to 4pm" or "What does my week look like?"
• Organize lists: "Create a new list called Side Project" or "Make Work my default list"
• Adjust settings: "Set my work hours to 9am-6pm on weekdays"
• Chain complex requests: "Schedule my top 3 overdue tasks for today and tomorrow"

The assistant asks for permission before reading your data or making changes — you always see a preview before anything happens. Pro users get access to the most capable AI models.

For the full list of capabilities, slash commands, and tips, see the AI Chat Assistant guide.

Mobile UI

On mobile devices with smaller screens, the UI adapts to show one panel at a time instead of the full desktop layout. Below the header menu, either the Task Hub or the Calendar is displayed. The Add New Task Panel appears as an overlay.

You switch between these views using the bottom navigation bar:

• Task Hub — your task lists
• Calendar — the calendar timeline
• Add Task — opens the task creation overlay

The AI Chat floating button remains accessible on all screens, making it a quick alternative to navigating between panels.

Keyboard Shortcuts

Trevor AI supports keyboard shortcuts on desktop for faster navigation and task management. See the full Keyboard Shortcuts reference for a complete list.
