Switch between them
- Consolidate overlapping AI assistant subscriptions (ChatGPT, Claude, Gemini, Perplexity, Grok, Copilot)If you pay for two to four AI assistants, run a one-week, side-by-side test on your real tasks with a provided prompt set and scoring sheet, check which assistant your Google Workspace or Microsoft 365 plan already includes, and cancel the rest at their renewal dates. Some heavy users will rightly keep two; the test tells you which.easy1 hour to set up$0 extrauses
- Drop Grammarly when you already pay for ChatGPT, Claude, Gemini or CopilotIf you already pay for an AI assistant, prompts handle rewrites, tone and careful proofreading, and built-in checkers (Google Docs, Microsoft Editor, Apple Writing Tools) cover everyday spelling and grammar. What you genuinely lose is Grammarly's real-time underlines everywhere you type, plus plagiarism checks, AI detection and team style guides on paid plans.easy30–45 minutes$0 extrauses
- Stop paying for Otter: use the transcription and AI notes already in Meet, Teams or ZoomMany business plans already include meeting transcripts and AI notes: Google Meet transcripts and 'Take notes for me' on eligible Workspace editions, Teams transcription (with AI notes via Teams Premium or Microsoft 365 Copilot), and Zoom's built-in meeting summaries on eligible paid plans. Check what you have, fill gaps with a transcript-to-action-items prompt, and handle recording consent properly.easy30–60 minutes$0 extrauses
