Cloud AI services go down. When yours does, anyone who built their workday around a single chat window just sits there hitting refresh. The fix takes about ten minutes and you only have to do it once.
Pick a backup from a different vendor
If Claude is your primary assistant, make ChatGPT or Gemini your alternate. If you live in ChatGPT, flip it. The key is a different company. A backup that shares infrastructure with your main tool goes down at the same time your main tool does, which is exactly when you need it.
Load your context before you need it
The backup is useless if it knows nothing about you. Paste your context file into the alternate’s custom instructions or a saved project today: who you are, how you work, the standing facts about your current projects. When the primary goes dark, switching takes a minute instead of a morning spent re-explaining yourself to a stranger while a deadline ticks.

Bookmark the status pages
Three URLs worth saving now:
- status.openai.com for ChatGPT and the OpenAI API
- status.claude.com for Anthropic and Claude
- Google Workspace Status Dashboard for Gemini
These pages tell you in seconds whether the problem is your Wi-Fi or their servers. When it’s them, stop retrying and switch.
Do one real task in your backup this week
The part most people skip is the fire drill. Run one actual task in the alternate while nothing is on fire. You’ll find the gaps in your context file, the prompt habits that don’t carry over, and the one thing the backup does better than your primary. Better to discover that on a quiet Tuesday than during a client delivery.
The bonus use case: cross-model review
A spare assistant pays off on good days too. A study across seven model families found that stronger models favor their own answers more when those answers are wrong. In an October test of 900 review sessions with planted errors, a same-model review combined with a cross-model review caught 57% of mistakes. Two passes by the same model caught only 43%. Before anything important goes out, paste it into the spare and ask what the first assistant missed.
