Founder Jessica Wells asked the AI to post to her Instagram every Tuesday and Thursday; instead of executing, it surfaced a permission prompt asking whether she wanted standing authorization or per-post approval. Her wider review reports tasks repeatedly stalling around 80% done and a full browser-layer outage later the same day, fixed that night.
This only partly worked. Worth knowing before you try it.
Checked 15,000 Instagram followers to find who doesn't follow back
Marco H asked the AI to audit his 15,000 Instagram followers and identify which ones don't follow him back. The agent worked through the full follower list and returned the non-follow-backs.
Scheduled a daily two-host AI-news podcast that saves to the Library and
The reviewer set up a scheduled daily AI-news briefing in an AI app as a two-host podcast saved in the app's Library, with an RSS feed for following in a podcast app. It worked, though the newest episode shown was dated two days earlier, flagging a freshness caveat on daily generation.
Checked last activity of every followed Instagram profile and listed inactive ones
A shipwithmuse automation recipe has the AI find dead follows: the agent checks the last activity date of every profile you follow on Instagram and returns a list of inactive ones to unfollow.
Built a school newsletter and permission slip from scratch for a school
One of eight hands-on tests run on the reviewer's real accounts; the AI scored 42.5/47 overall across the gauntlet.
Delivered unsolicited fantasy-football reports five days a week (Monday recaps, Wednesday waiver-wire reports)
2026, a host described playing fantasy football in two leagues while the AI sends weekly performance reports every Monday night and waiver-wire reports every Wednesday — unsolicited football advice about five days a week. Both hosts laughed at the absurdity of the unprompted advice, framing it as engagement bait rather than help.
This only partly worked. Worth knowing before you try it.
My agent listed every empty course before the semester and caught one open too early
He directs academic tech at a university. Every semester some instructors never set up their courses, so students walk into empty course pages. A day after signing up, he had the AI build a CSV of upcoming courses with no content, or where the instructor has never entered the course. The list also told him one course was already open to students when courses should not be open yet, so he closed it.
He moved his external-brain agent from the AI to the AI, with a capture bot filing every link
A Japanese engineer's September 2026 operations update: he migrated his personal agent Mana, with its memory, skills and routines, from the AI to the AI, keeping the same Markdown-and-Git external brain, a vault of about 470 wiki pages. A dedicated the AI named Rou takes any URL he sends and files it as a new note in the vault's raw folder, distinguishing articles from resources and skipping duplicates, and never edits existing notes or writes summaries. Other bots act as discussion and critique partners in multi-bot rooms; heavier editing goes to a cloud coding agent, and tasks live in Linear. He published Rou as a public the AI template anyone can copy.
Built a Google Sheets wedding-vendor tracker with tabs for Welcome/Mehendi, Sangeet, Wedding, and Reception
Vanshika Singhania (2.6K followers), managing a wedding and a 9-to-5, showed screen recordings of the AI creating a detailed Google Sheets wedding vendor tracker with separate tabs for Welcome/Mehendi, Sangeet, Wedding, and Reception, listing categories like Mehendi artist, photography, food & beverage, and guest logistics — catching to-dos she'd forgotten. Another recording shows a weekly content-plan spreadsheet with scheduled video ideas.
