Gemini versus other AI-powered productivity solutions (ClickUp as an example)
In the professional sphere, tools have emerged that complement or expand upon what Gemini offers in Gmail. One frequently mentioned example is ClickUp with its own assistant. ClickUp Brain, which is more deeply integrated into project management.
While Gemini focuses primarily on Read emails, write replies, and create text in Google appsClickUp offers an environment where you can Send and receive emails, turn them into tasks, associate them with projects, automate sending, and centralize communication with the rest of your work on a single platform.
ClickUp integrates with Gmail, Outlook, IMAP, and Microsoft 365, and allows Generate email drafts with quick commandsAdjust tone and creativity, and send them without leaving the workspace. Furthermore, by being able to automate emails based on task or form statuses, it becomes a more comprehensive solution for anyone who needs something more than an “email writer”.
In parallel, ClickUp Chat seeks to reduce email overload by moving many internal conversations to real-time chats linked to projectsthus minimizing the number of emails you actually need to answer.
Gemini as the engine for intelligent chat apps in Google Chat
Beyond Messages and Gmail, Google also uses Gemini as the brain of Google Chat applications that answer questions based on conversationsAn advanced example is a chat app that acts as a knowledge assistant for new employees.
This app integrates with Vertex AI (Google Cloud's AI platform) using Gemini models and relies on Google Workspace Events, Pub/Sub, Firestore, Eventarc and Cloud Functions to listen in real time to everything said in a chat room. From there, it stores the messages, detects when someone asks a question, and respond based on previous answers from the same space.
How Does It Work?
The general flow works like this: when someone adds the app to the space, the app requests authorization, It downloads the message history using the Chat API and saves it in Firestore.Create a subscription with the Google Workspace Events API to receive new messages via Pub/Sub and Eventarc, and publish an introductory message.
When a user types a message in the space, the app receives the event, It saves it in Firestore and sends it to Vertex AI with GeminiThe instruction passed to Gemini tells it to check if the message is a question; if it is, it should respond based on its saved history. If it finds a viable answer, the app Publish the response in the chat space using the Chat APIIf not, you can even mention the space administrators so that a human can respond.
This app keeps listening for subscription lifecycle events (to renew it when it's about to expire) and, when it's removed from storage, Delete the subscription and clear the data from that space in Firestore.Thus, the system learns continuously from conversations and becomes a kind of dynamic FAQ trained by the company itself.
Summary architecture of the solution with Gemini
To bring this chat app that uses Gemini to life, the following are combined: various services:
- Vertex AI API with Gemini: It handles the generative AI part, understanding the questions and generating answers.
- Google Chat API: allows you to receive messages, list the history of a space, post replies and configure the app (name, avatar, etc.).
- Google Workspace Events API: It is used to subscribe to changes (new, edited, deleted messages) in Chat spaces and receive notifications.
- Firestore: stores information about spaces, messages and users, acting as a knowledge base accessible to AI.
- Pub/Sub and EventarcThey manage asynchronous events from Workspace Events to the Cloud Functions that process the messages.
- Cloud Functions (app and eventsApp)They process both direct Chat interactions and Pub/Sub events, without the need to manage servers.
- Cloud Build and Cloud RunThey are responsible for compiling and running the code in containers, in a fully managed environment.
This example demonstrates that Gemini is not only useful for compose messages in Messages or Gmailbut also as a core of tailored solutions that answer questions, learn from conversations, and integrate with complex infrastructures.
The integration of Gemini into Messages, Gmail, and Google Chat shows how Google's AI is moving from a curiosity to becoming a a constant assistant for writing, summarizing, responding, and managing informationAs long as you are clear about its limits, review what it generates, and control your data, it can become a truly powerful tool for saving time, reducing email and message overload, and maintaining smoother conversations without losing your own style.
