带学习能力的 agent 阅读聊天器An agent reading-chat with a learning loop
我的第五个项目。功能与定位是一个 agent 阅读聊天器，但又结合了学习能力。
三个核心能力
1. 子 thread 聊天
它是一个 AI chat 软件，但支持子 thread 能力——允许你在聊天中开启新的分支，保留清晰的 context，轻松深入任何你好奇的领域。
2. highlight → flashcard
它是 agent 辅助的 flashcard 软件。当你阅读了好奇的内容，将想要学习与记忆的内容进行 highlight，agent 会为你的 highlight 生成 flashcards。
3. 语境生词卡片
因为我想阅读英文内容、直接学习原文，所以引入了 Aletheia 中做过的生词卡片能力：它能结合 context 查询生词的语境义，并且允许收藏生成单词卡片复习。
Aletheia 是实验室；Trace 把那条 highlight → 结构化 → 卡片流水线，打磨成专注阅读场景的独立产品。
Trace 把前面几个项目的脉络收拢在一起：创客计划的复习交互、Aletheia 的语境查词、以及 agent 驱动的阅读与学习流程。
My fifth project. An agent you read and chat with, but with a learning loop built in.
Three core abilities
1. Sub-thread chat
It is an AI chat app that can open a new branch mid-conversation, keep context clean, and let you go deeper wherever curiosity pulls.
2. Highlight → flashcard
It is also an agent-assisted flashcard app. Highlight what you want to learn; the agent turns those highlights into cards.
3. In-context vocabulary cards
I want to read English in the original, so Trace inherits Aletheia’s vocabulary cards: look up a word in context, save it, and review it later.
Aletheia is the lab; Trace takes that highlight → structure → card pipeline and shapes it for reading.
Trace also gathers the earlier line of work: Maker Plan’s review gestures, Aletheia’s in-context lookup, and an agent-driven loop of reading and learning.
