Privacy reality

• Hosted ChatGPT / Claude / Gemini — your prompts go to the provider. Most have a "don't train on me" toggle now (ChatGPT Settings, Anthropic respects opt-out by default for API + Pro). Read the policy.
• Notion AI / Workspace Gemini / Microsoft Copilot — your workspace data is sent to the provider but typically not used for training.
• Apple Intelligence is on-device or via Private Cloud Compute (Apple's enclave) — strongest privacy story among hosted AIs.
• ★ Local Ollama / LM Studio — fully local; nothing leaves your machine; the privacy default if you have a recent Mac or a GPU.

Pricing reality check

• ChatGPT Plus / Claude Pro / Gemini Advanced / Perplexity Pro all hover around $20/mo.
• ChatGPT Pro / Claude Max are $200/mo tiers — for heavy use only.
• Notion AI is +$8/mo on Notion subscription.
• Apple Intelligence is free if you have the hardware.
• Ollama / LM Studio / Open WebUI / Jan / GPT4All / AnythingLLM are free OSS; "cost" is hardware (a 32GB Mac runs decent 8B–14B models).
• Granola ~$25/mo; Read.ai ~$15/mo; Otter.ai has a useful free tier.

Patterns that actually work

• ★ Don't ChatGPT what an editor / template would do. Boilerplate is faster from a snippet (see prod-text-expansion).
• Memory + Custom GPTs for repeated workflows — set up once, reuse.
• AI for first draft, you for final. Edit ruthlessly; AI prose has tells.
• Run summaries through "what would surprise me?" — the surprises are what's worth keeping.
• Local first for anything sensitive — health, financial, HR.
