Hindsight
Keep the last few minutes, so you don't have to.
Someone walks up and says something you'll want to check later, but it's over before you'd think to record. Hindsight was already listening: it keeps the last few minutes in memory and forgets anything older. When it matters, you save it.

Go back to when it started
Choose… opens a timeline of everything Hindsight holds, up to three hours. Quiet stretches show where a conversation began: drag the start and the end there, listen to check, and save exactly that.

From the menu bar
Save the last minute, 5 minutes or 15 minutes, or open the timeline, without opening a window. A shortcut you choose saves from any application.

Pick your colors
Rhodonite, Itrium's own, or one of three Catppuccin flavors, each in light and dark. Every palette meets level AA contrast, which we check before any of them ships.

The details
In memory only
Nothing is written to disk until you save a clip. Until then, the last few minutes exist only in memory.
Encrypted while it waits
The buffer is encrypted with a key that exists only while Hindsight runs, so even if your system swaps memory to disk, it writes scrambled bytes.
Never leaves your computer
Hindsight makes no network requests. Clips are ordinary audio files in a folder you choose.
Up to three hours
Keep 15 minutes or up to three hours. Three hours takes about 22 MB of memory and a little over one percent of a processor core.
A fallback microphone
Record from your phone or a headset; if it disconnects or goes quiet, Hindsight switches to a fallback and back again by itself.
Your clips, playable anywhere
Play clips inside Hindsight, or export them as WAV for any other application. Delete them for good when you no longer need them.
Starts when you log in
Hindsight can start quietly in the menu bar when you log in. It's off until you turn it on, since starting means recording.
Recording people
In many places, recording a conversation needs the consent of everyone in it. Hindsight shows that it's recording, and your system shows its microphone indicator, but whether recording is allowed where you are is up to you. Let the people around you know.
Download
Your computer will ask you to confirm, once
Signing certificates cost money every year, and Hindsight is free, so it isn't signed by a verified developer yet. It's built from its public source code, on GitHub's machines, but your system can't know that, so it asks the first time. It will also ask whether Hindsight may use the microphone.
