Abuse and rights
GrabIt rights or acceptable-use reports should include the media title, claim and relevant links.
Sangam
Every source on one clock. A microphone you can leave on.
- Live app playback can stay on Core Audio's direct path while Sangam aligns the copied mix. Version 1.2.2 measured a 32 ms Sangam path on the tested studio setup; total delay depends on sources, hardware and the receiving app. Cameras may need a measured A/V correction. For self-monitoring use your interface's direct monitor.
Shruti
Per-app volume, EQ and output control for Mac.
Relay
Control your Mac from your iPhone.
- Mac 0.2.2 build 45 is the downloadable testing companion; the Relay iPhone app is required and public iPhone delivery is not available yet. No checkout is open.
- Older Mac copies require one initial download before signed automatic update checks work. Installation is confirmed by the user.
- Physical gestures, clean-user/device recovery, second-Mac acceptance and final privacy review remain open; Watch testing is deferred.
Prism
One player for media, scores and MIDI.
- The Mac build is Apple silicon and macOS 15 or later only; tested on two Macs so far (Mac mini M4 Pro and MacBook Pro).
- Windows and Linux are 64-bit x86 only. There is no Arm build of either yet, and neither installer is signed: Windows shows More info, then Run anyway, the first time.
- On Windows, a file type you have already assigned to another app by hand stays with that app, because Windows protects that choice. Prism says so on the setup screen rather than working around it.
- The Windows and Linux build opens files on your own computer. Online links, Instagram and YouTube playback, and the sampled piano for MIDI are on the Mac build only.
- Private or unavailable Instagram posts show a clear message with an Open original button; DRM-protected media does not play.
- Instagram native playback and YouTube playlists need GrabIt installed.
- Copies without an updater need one initial download. Current builds discover signed compatible updates; installation and relaunch require your choice.
GrabIt
Capture a lesson. Keep the useful moment.
- GrabIt 1.23.1 build 41 targets macOS 13 or later, with durable incremental indexing and user-confirmed signed updates; a found update shows an Update available button in the main window. Studio runtime acceptance is on macOS 15.6.1; each installation requires an explicit choice.
- Paid checkout and paid activation are closed. Paddle's published acceptable-use policy lists streaming downloaders among prohibited categories; product eligibility and the complete purchase, recovery and refund journey are not cleared.
- The matching FFmpeg 9.0.2/x264/LAME source archives, pinned build recipe and provenance accompany this release. This does not provide matching source for older provider-built FFmpeg releases.
- Windows 10/11 and Linux ports are unfinished; there are no installable packages for them. Physical Intel/macOS 13, clean second-Mac and restricted-source acceptance remain open team checks.
Kosh
Know every drive: what's on it, how healthy it is, what it's good for.
- Apple silicon and macOS 14 or later only; tested on one Mac so far.
- Many USB enclosures do not pass the drive's own health data through; Kosh then relies on macOS error counts and its read check, and says so.
- Copies before 1.0.3 were team-only and need one download of the current version to join the public update channel.
Groove Metronome
A metronome that teaches groove, on the Mac.
- Copies older than 1.3.1 have no in-app updater and need one download; after that, signed updates arrive inside the app and install only after the user's choice.
- Runtime verified on Apple silicon; the Intel slice has not been run on a physical Intel Mac.
Chorale
Live vocal harmonies, steered by your voice or the chords you play.
- Shifted voice artifacts remain possible on breaths, very low notes and extreme intervals; the dry path is immediate inside the processor.
- Tested on one studio Mac; the Intel version has not been run on a physical Intel Mac.
- Copies before 1.14.2 used a private team update check; team copies of 1.14.1 receive 1.14.2 through it, older copies need this download once.
Riyaz
From a pencil sketch to a part you can rehearse, on the Mac.
- Copies older than 1.6.0 were internal and have no updater; 1.6.0 is the first public build and updates itself from here on.
- Runtime verified on Apple silicon; the Intel slice has not been run on a physical Intel Mac.
Cue
The browser for people who make things.
- If Google refuses to sign you in, it is almost always old cookies rather than Cue: a sign-in copied from Chrome gets cancelled and leaves remains behind. Signing in to Google in Cue empties that folder's Google cookies first and then opens Google's own form.
- Passkeys are not supported; that needs Apple's browser permission or our own Chromium build.
- The cache limit is per login rather than per site.
- WhatsApp keeps its link in its own storage rather than in cookies, so it cannot be carried from Chrome: each login scans the code once.
- Safari’s saved sign-ins cannot be read at all, because macOS protects that folder from every other app.
- Simple Chrome extensions copy in and work; ones that need Chrome's own toolbar APIs may not.
- Importing Safari bookmarks needs Full Disk Access for Cue in System Settings, because macOS protects the Safari folder. Chrome, Helium, Brave, Edge and Arc import without it.
- Windows and Linux builds come from GitHub Actions and are not code-signed yet.
NSM Flow
Free, open-source dictation with local speech recognition and Indian vocabulary support.
- The Windows installer is not yet signed with a Microsoft certificate, so Windows shows "Windows protected your PC" the first time. Click More info, then Run anyway. The Mac packages are signed and notarized by Apple.
- Automated cross-platform installer builds do not replace a real dictation and paste test on physical Intel Mac, Windows and Linux hardware. Linux distribution/Wayland support and automatic updates are not certified.
- The India vocabulary is curated rather than exhaustive; testers should report missing spellings with the exact dictated phrase and expected output.
