Sack AI assistant
Solving key challenges in asynchronous team communication
Teams distributed across time zones wake up to hundreds of unread Slack messages. Opening messages to see what's important means losing track of what's new. But ignoring them risks missing urgent items. The workaround is scanning message previews and trying to remember which ones looked important, which breaks down after about 20 messages.
About this tool

This assistant connects to Slack workspaces and accesses unread messages through the Slack API without changing their read status. Users interact through text or voice to ask about message content. The system uses GPT-5 for text processing and GPT-Audio for voice interactions. You can ask "What did I miss overnight?" and get a summary of unread messages.
Built with Slack workspace integration, text and voice query interface, and GPT-5 and GPT-Audio processing. This ensures unread message triage with channel-specific filtering, admin controls, and MongoDB storage.
Team members check what's urgent before opening Slack. They see summaries of overnight messages and can identify which threads need immediate attention. The assistant preserves unread status, so nothing gets lost in the mental shuffle.
Prompts used to build this app
I want to create an app that will allow me to chat with all of my unread messages on Slack. So I want this app to connect to my Slack account, get all of the unread messages for me, show me all the unread messages, show me the number of unread messages. I want to have a refresh button right there on the homepage so that I can refresh it. And I want to be able to view all of the unread messages individually by channels. So just have a list of channels or maybe a dropdown, view all messages. Then inside it, there should be grouped by channels. And if I click on each one, I should see it expand to actually all of the messages that are unread in that channel. And most importantly, I want to have on the bottom of the screen an input field to start chatting with AI with my messages. So I want you to use either GPT-5 or GPT-Audio LLM model. Actually, you can use GPT-Audio. And in it, I want you to send all of the unread messages and whatever audio that I sent. So I want to be able to click, record my voice, and I want to have some nice animation. All that's happening. And when I click send, that's when it sends the message to GPT-Audio. And I want a textual response about everything that LLM said. So use OpenAI's API. And also, when I start recording, I want to be able to cancel the recording so nothing happens.
Please change the bottom footer for recording and sending a text message on the homepage. It's too high. I want this to be a very slick, on the bottom of the page, input field, and on the side there should be a record button. And I also want to remove the footer built with love with using Pythagoras.
Ok, chatting works now but whenever I send a message, previous messages get deleted. Also, audio sending still doesn't work. It gives me this message response:It seems like your question is incomplete or cut off. If you could provide more details or clarify what you would like to know, I'd be happy to assist you!
