Tine

Product Introduction

1. Definition: Tine is an AI-powered system-level assistant for macOS, implemented as a "second cursor" integrated into the MacBook's notch area (Dynamic Island). It functions as an operating system agent or AI copilot that operates directly within the user's workflow across all applications, unlike traditional chatbot interfaces.
2. Core Value Proposition: Tine eliminates context switching and manual repetitive work by observing the user's screen context—including the active application, text selection, and recent actions—and executing multi-step tasks across apps autonomously upon voice or keyboard command. Its core promise is to be an always-available, on-screen agent that performs busywork while the user remains in control.

Main Features

1. Screen-Aware Context Engine: Tine continuously monitors the active application window, current user selection, and interaction history (e.g., recent clicks and keystrokes). This "always watching" capability allows it to understand the immediate workflow without requiring users to copy-paste context or re-explain tasks, forming the basis for its assistance and automation functions.
2. Inline Ghost Text Drafting: An AI writing assistant that operates "where you type." As the user composes an email, document, or message, Tine suggests completions, drafts, or rewrites as ghost text directly within the text field of any application. It adapts to the user's specific tone and phrasing, and accepts suggestions with a single keystroke (Tab), enabling seamless, in-context editing.
3. System-Level Cursor Automation & Multi-Step Task Execution: When given a goal, Tine can "take over" and control the mouse cursor itself to navigate through complex, multi-step workflows across different applications, tabs, and screens. It logs every action it performs, and the user can instantly regain control by touching the mouse or using a dedicated hotkey (⌘⇧␣).
4. Notch-Resident Dynamic Island Interface: Tine lives in the MacBook's notch, displaying a live activity log of ongoing tasks. It provides a "perch" for one-tap task initiation and status monitoring, eliminating the need to manage separate windows or applications, thereby streamlining workflow visualization.
5. Teach-by-Demonstration Skill Recording: Users can perform a task once manually, and Tine records the sequence of clicks and keystrokes, transforming it into a named, repeatable skill. This recorded automation can be invoked later to perform the same task hands-free, adapting to dynamic screen content.

Problems Solved

1. Pain Point: Eliminates the productivity loss caused by constant context switching between applications and the need for repetitive manual data entry or navigation. Tine addresses "busywork" such as form filling, routine email replies, expense reporting, and multi-app data transfer that consume significant time without adding strategic value.
2. Target Audience: Designed for knowledge workers, developers, managers, and any power user on the Mac platform who spends significant time performing administrative tasks, communication, and information management across multiple applications simultaneously. Ideal for roles like marketers managing social posts, developers coordinating across Slack and Jira, or executives handling schedules and correspondence.
3. Use Cases:
   • Everyday Task Automation: Instructing Tine to "reply to Sarah and book a room" results in it drafting an email in your voice within Gmail, searching for available rooms, and navigating the booking interface.
   • Inline Writing Assistance: Composing a client proposal in Google Docs, with Tine suggesting entire paragraphs that match your style and context as you type.
   • Expense Reporting: After selecting receipt images, commanding Tine to "file expenses" triggers it to upload documents, match them to categories, and proceed through the submission workflow.
   • Skill Replay: After manually teaching Tine to export data from a database, generate a pivot table in Excel, and upload it to a cloud drive, you can later simply say "run weekly report," and it will execute the entire sequence.

Unique Advantages

1. Differentiation: Tine fundamentally differs from traditional chatbots and assistants by operating at the system level, not within a sandboxed application window. It acts across your real applications, using the same interfaces a human would, rather than relying solely on APIs. This gives it unparalleled access to perform complex, cross-application tasks.
2. Key Innovation: The key innovations are its persistent screen context awareness, its on-device execution by default for privacy and speed, and its unique interaction model that combines three modes—watching, suggesting (ghost text), and autonomous action—within a unified, notch-resident interface. This creates a true "second cursor" that collaborates rather than just responds.

Frequently Asked Questions (FAQ)

1. Is Tine an AI chatbot like ChatGPT? No, Tine is a system-level AI agent and cursor automation tool, not a conversational chatbot. It doesn't exist in a separate chat window; it lives in your Mac's notch, observes your screen context directly, and interacts with your real applications (like Gmail, Slack, Chrome, Finder) by controlling the cursor and typing, just as you would.
2. How does Tine handle privacy and data security? Tine is designed with a privacy-first architecture. It runs on-device by default, meaning processing happens locally on your Mac. It only accesses the specific screen content you allow, requires your explicit approval for each takeover task, and nothing leaves your machine without your consent. A dedicated hotkey (⌘⇧␣) serves as an instant kill switch.
3. What exactly does "second cursor" mean? It means Tine is an AI that operates alongside your primary cursor. It can suggest text inline where you type (ghost text), and when activated for a task, it can drive the cursor itself, clicking, scrolling, and typing across multiple apps to complete a goal, all while displaying its progress in the Dynamic Island. You can pause it instantly by touching the mouse.
4. What kind of tasks can Tine automate? Tine excels at end-to-end multi-step tasks that involve switching between several apps or performing repetitive clicks and entries. Examples include: compiling research from the web into a document, filling out complex forms with information from an email, posting content across multiple social platforms, or following a standard operating procedure that you've recorded as a skill.
5. How is the "Teach by Demonstration" feature different from other automation tools? Traditional automation tools often rely on scripting or fixed macro recording. Tine's system allows it to learn tasks by watching you perform them once in your native applications. It then converts that sequence into a named, replayable skill that can adapt slightly to variations on the screen, offering a more intuitive and flexible way to create custom automations without coding.
