As answered by people managing TurnShift and GroupSync.
TurnShift's answer
TurnShift's answer
You see and change everything on one calendar. Select days, pick someone, done. Most shift tools send you through forms and settings pages for that. TurnShift then tells people in the Slack or Microsoft Teams channels they already read, and you can run it all from Claude or ChatGPT through its MCP server.
TurnShift's answer
A schedule takes a few minutes to set up, and assigning a month takes seconds. You only pay for people on an active schedule: with 300 people in Slack and 5 on a schedule, you pay for 5. It is one plan with every feature, 3.50 EUR per person per month billed yearly, and a 14 day trial with no card.
TurnShift's answer
Team leads and admins at small and medium companies who share a duty: support, on-call, the front desk, office chores. They are on Slack or Microsoft Teams and want to stop asking "who is on today?" in a channel.
TurnShift's answer
Vincent Voyer built TurnShift in France in 2020, as a simple shift calendar connected to Slack: a team calendar for recurring tasks like PR reviews, who's on support or who's qualifying leads. Algolia, its oldest customer, shares its customer support duty with 50+ engineers on it. In 2026 it got automatic rotations, four languages, free tools and Microsoft Teams.

I was lucky to be part of the beta for my SaaS (https://turnshift.app) and I must say this new feature simplifies things A LOT. Especially as a EU business owner, I previously had to sync every VAT tax rate possible, use a complex... - Source: Hacker News / over 5 years ago
