AI agent use cases from Wednesday, October 21, 2026

Find the cheapest holiday flight across several nearby airports, rides included

The poster and his fiancée needed flights from Chicago to Connecticut over Thanksgiving week, with 5 to 7 airports within a two-hour drive of where they were going. They also had to fit departure and return times around dropping off and picking up their dog. He asked Meta Muse to work it out, and he says it compared flight plus Uber cost from each airport, came back with the three best options for time and money, and gave him a link so he only had to click purchase. He says it saved him 30 to 60 minutes.

Watch ticket prices for a big game and buy when they drop

The poster asked Muse to find 4 lower-level seats for a college football game, check prices every day and look through Facebook groups every hour. He says the best price at first was $892 for the four. A week before the game Muse found 4 seats for $500, and he bought them.

He says he saved $392 compared with the first price. We have not verified this.

Book the doctor visit you keep putting off

The poster had put off a skin check for years because finding a doctor felt like too much work. He asked Muse to find a dermatologist. He says it found three in his insurance network, booked one around his calendar and sent in his paperwork, and the whole thing took about 30 minutes of his time.

Get Telegram voice notes turned into text in the chat

The poster made Telesec, a free open-source plugin that connects Hermes Agent to Telegram Business. Voice and video notes are turned into text in the same chat: his own short notes get the transcript as a caption, and the rest get it as a reply. It uses the speech-to-text already set up in Hermes.

Her agent setup got wiped and there was no backup

The poster says something wiped her Hermes Agent setup and she didn't have a proper backup. She has spent about two weeks fixing it on and off. She has backups now, and says the mess showed her how much of her work had moved to the agent.

Turn a job you just walked your agent through into a skill

After a work session with Hermes Agent, the poster asks it to turn what they just did into a skill, so he doesn't have to explain the process again next time. Since a bloated setup hurts results, he also has it check its own setup now and then: prompt size, skills, memory, scheduled jobs and permissions.

Have an agent go through your internet and phone bills and ask for a lower price

The poster sent Grok Bot his internet and wireless bills as PDFs and asked it to lower the total without losing features. It found no better competitor deal, but it found that his provider sold the same internet plan for less than he was paying after two years of price rises, plus a $20 a month phone add-on he didn't use. He signed in to the account himself, then watched Grok Bot use the provider's customer service chat, and he told it to confirm the new monthly total before agreeing to anything. He also had to ask it to slow its replies down. It set a reminder for when the promo price ends.

He says the bill is now $45 a month lower. We have not verified this.

Turn an X list on any topic into a news page that updates every hour

The poster put his "best in AI" X list into Grok Bot and asked it to write him a news page from what those accounts are saying. He says it now reads the list every hour and rebuilds the page, after about 10 minutes of setup. He suggests doing the same with any list, like your football team plus the journalists who cover it, and says the page could also be turned into a script for a podcast.

Scheduled reminders got mixed in with regular chats after a Gemini update

The poster uses Gemini Spark to schedule tasks and send reminders at set times. After a recent update to the Gemini chat screen, the separate Spark tab is gone for him, so chats from scheduled tasks now sit among all his other chats and are harder to keep track of. He has asked Google to bring the separate tab back.

Find the emails that need a reply and get drafts written in your tone

The poster connected Gmail to Claude Cowork and asked it to go through the inbox. They say it read 23 emails, picked out the 7 that needed a reply and wrote a draft for each in their tone, in about 45 seconds. They also set it up to look for emails nobody had answered in 3 or more days, and to run the check every morning.

Match raw video clips to a client shot list and rename them for delivery

A UGC creator gives ChatGPT Work access to a Google Drive folder of raw footage, along with the client brief and their file naming system. They say it reviews the videos, matches each one to the shot list and renames the files. They put it at about 90% accurate and still check every file, but say it has cut their file prep before client delivery a lot.
