Practice environments for everyday office tools

alttab is a free set of browser exercises for everyday office work — inbox triage, phishing awareness, CRM data hygiene, spreadsheet accuracy and typing speed — each in a faithful recreation of a tool you already use. No account, nothing to install.

Choose an environment

• Excel Practise spreadsheet accuracy: spotting the one value that breaks a column, auditing formulas for the wrong range, and catching duplicate records before they ship.
• Figma Practise a designer's eye: aligning an element to the pixel, judging small differences between colours, and rebuilding a layer stack in the order a design needs.
• Notion Practise keeping a workspace tidy: filing notes where they still make sense a month later, spotting duplicates, and a daily word to sharpen vocabulary.
• Outlook Practise working an inbox: triaging messages under time pressure, filing mail by type, telling a genuine message from a phishing attempt, and routing tickets to the right queue.
• Microsoft Teams Practise the rhythm of team chat: typing at speed on real message text, reading a scrambled thread back into order, and picking the reaction a message calls for.
• Slack Practise staying on top of a busy channel: fast, accurate typing on the text of a working day, ordering a jumbled conversation, and matching the right response to each message.
• Salesforce Practise CRM data hygiene: moving opportunities to the correct pipeline stage, scoring inbound leads, spotting duplicate records, and routing tickets to the team that owns them.
