I built an open source meeting recorder that runs on your laptop and drops any note it can't cite

说明与用途

SayBack 是一个本地桌面应用，记录会议、转录音频、总结内容，并将每条笔记链接到其源时间戳，保护隐私并避免云依赖。

问题

Meeting tools often record audio but discard visual context and require cloud accounts, making it hard to recall why decisions were made.

结果

SayBack provides a fully local meeting recorder that produces source‑linked notes, preserving privacy and enabling easy navigation back to the original content.

工作流

• Select microphone, window or screen, and system audio sources
• Record meeting
• Transcribe audio with timestamps using whisper.cpp
• Summarize transcript into key points, decisions, action items and questions using a 4B model and screenshots
• Generate note items with source IDs
• Validate source IDs against existing transcript blocks
• Drop items with no valid sources
• Organize meetings into folders and enable full‑text search
• Click a note to jump to the corresponding video timestamp

证据

After a meeting, I usually remember the decision. I rarely remember why we made it.

SayBack: an open source desktop app that records the conversation and what was shared, then writes notes where every point links back to the exact moment it came from.

来源

In local mode, nothing leaves the computer. SayBack even refuses Ollama models that are really cloud models behind a local alias, before any data is sent.

One invented citation removes one item, not the whole summary. If nothing survives, the analysis fails with an error instead of showing you unsupported notes.
