## Pi 個人 AI 助手

Pi（意指 "personal intelligence"，個人智慧）是由 Inflection AI 開發的對話式 AI 助手。它並不把自己定位成一次只回答一個問題的高效工具，而是為開放式對話而生：梳理一個艱難的決定、為一次棘手的談話做準備、釐清某個問題，或者在一天結束時找個對象說說話。

在陪伴之外，這款應用還提供不少實用方向。你可以用它探索新話題、練習外語、把想法整理成行動計畫、進行腦力激盪，或取得觀影推薦。語音模式讓你可以直接說出想法並聽到 Pi 的回應，實現免持操作的即時交流。

Pi 在 App Store 免費下載，含 App 內購買項目，年齡分級為 18+。Inflection AI 將其描述為富有情感智慧、以人為本的 AI，使用者評價也普遍稱讚它支持性的語氣以及跨對話記住上下文的能力。

**價格與方案:** 免費下載使用，含 App 內購買選項。細節請以 App Store 頁面為準。

- **自然對話:** 圍繞決定、困惑或靈感暢所欲言，助手經過調校，能給出有支持感、像真人般的回應。
- **即時語音模式:** 直接對著 Pi 說話並聽到回答，做家事或忙別的事情時也能免持交流。
- **跨對話記憶:** Pi 會逐漸了解你的偏好並引用先前的對話，讓建議始終貼合你的情況。
- **多種日常用途:** 抒發心情、準備難題談話、練習語言、腦力激盪、制定行動計畫或取得推薦。
- **由 Inflection AI 打造:** 開發方是一家專注於情感智慧、以人為本 AI 的公益性公司，而非通用聊天機器人。

**優勢:** 免費下載，語氣溫暖自然; 語音模式讓免持交流真正可用; 能跨對話記住上下文，建議具連續性; 由專注情感 AI 且具公益屬性的公司開發

**限制:** 不同會話之間的對話品質與記憶表現仍不夠穩定; 有使用者回饋更新後語音模式等功能曾發生變化

## Reflection

Reflection is an AI-powered journaling app and personal growth coach available on iOS, Android, macOS and the web. It lets you write or speak your entries, responds with an AI coach in the moment, and answers plain-language questions about your own history.

**價格與方案:** Freemium. A free-forever plan covers unlimited private entries, cross-platform access, reminders, prompts, one photo per entry and basic analytics. Premium is about $8 per month (roughly $5.75 per month when billed yearly, around a 30% saving) and adds unlimited AI search and insights, unlimited AI writing support, unlimited cross-device syncing, custom templates and tags, multiple photos, rich-text formatting, advanced privacy settings and PDF exports. A 7-day free trial of Premium is offered.

- **AI Coach inside the entry:** Instant Chat replies on the next line as you write, and one-tap actions like Go Deeper or Get Perspective give you a fresh angle without leaving your journal page.
- **Voice calls and voice journaling:** Talk out loud in a real-time back-and-forth and save the transcript, or simply dictate an entry and let Reflection transcribe it.
- **Ask Your Journal:** Natural-language search across everything you have written, so you can ask about patterns, people or a specific period and get a plain-language answer.
- **100+ guided journeys and templates:** Structured programs on gratitude, anxiety, relationships and productivity, plus journaling templates, daily reminders and nine light/dark color themes.
- **Private by design:** AES-256 encryption at rest, TLS in transit, biometric or passcode lock, optional private share links, and a stated policy of never training AI models on your entries.

**優勢:** AI coach and voice conversation are integrated directly into the journaling screen rather than bolted on; Genuinely useful free tier with unlimited entries and no ads; Strong, clearly stated privacy stance: encryption, biometric lock, no AI training on your data; Available on iOS, Android, macOS and web with sync

**限制:** Premium is required for the most compelling AI features such as unlimited AI search and insights; The AI coach is a wellness companion, not a licensed therapist or medical service; Some of the deeper analytics depend on having weeks or months of entries built up
