## 關鍵功能與能力

- **AI email reply and compose:** Generate replies, draft new messages, and produce multiple phrasing options from a Gmail sidebar without breaking your workflow.
- **Multi-model AI chat:** Talk to several well-known AI models in one interface and pick the one that fits each research, writing, or summarization task.
- **Chat with PDFs and web pages:** Upload documents or point the assistant at a page to extract answers, summaries, and key points instead of reading everything yourself.
- **Trainable AI personalities:** Create custom personas for professional, casual, sales, or support writing and train them on your own tone so output matches your voice.
- **Automations and campaigns:** Set up recurring responses, scheduled follow-ups, and AI-assisted campaigns to cut repetitive sending work.

## 主要使用情境

- **Clear a shared inbox faster (Customer support agent):** Use AI summaries and reply drafts to answer common questions consistently and prioritize the messages that need human attention.
- **Keep outreach personal at volume (Sales representative):** Build a sales personality that mirrors your style, then generate tailored follow-ups and monthly touchpoints without retyping the same pitch.
- **Digest long documents quickly (Student or researcher):** Chat with PDFs and web pages to pull out key arguments and summaries, then translate or clean up your own write-up with the grammar tools.
- **Automate routine correspondence (Founder or small-team operator):** Create automated responses and follow-up sequences so repetitive emails run themselves while you stay on strategic work.

## 優勢

- Genuinely usable free tier with 5 AI replies per day
- Clear, low-cost paid plans including a $199 one-time lifetime option
- Supports multiple AI models instead of locking you to one provider
- SOC 2 and GDPR claims plus Google verification and a clean store record
