TRACE

Conversations leave traces.

A lightweight, local-first meeting companion for capturing conversations, transcribing them, and turning them into useful notes.

Everything runs on your machine. No API keys, no subscription, no per-meeting cost, and no audio leaving the computer.

Status

EARLY DEVELOPMENT — M0 (scaffold) complete. M1 (audio capture) is next.

Stack

Tauri 2 · Rust · React 19 · TypeScript · Tailwind v4 · Parakeet · Ollama · Markdown

How it works

mic + system audio ─► local transcription ─► your notes ─► local LLM ─► Markdown

Microphone and system audio are captured as two independent streams, so every transcript line already knows whether you said it or they did — speaker attribution without a diarisation model.

Markdown files are the canonical source of truth. SQLite is only ever a rebuildable index.

Setup

Prerequisites

Node.js	22+
pnpm	10+
Rust	stable, via rustup
MSVC C++ build tools	"Desktop development with C++" workload, incl. Windows SDK
WebView2	preinstalled on Windows 10/11

Rust and the MSVC toolchain are required for anything that touches src-tauri/. The frontend alone runs without them.

winget install Rustlang.Rustup
winget install Microsoft.VisualStudio.2022.BuildTools `
  --override "--quiet --add Microsoft.VisualStudio.Workload.VCTools --includeRecommended"

No winget? Install rustup and the Build Tools for Visual Studio manually, selecting the Desktop development with C++ workload.

Run

pnpm install
pnpm tauri dev     # full desktop app (needs Rust)
pnpm dev           # frontend only, in a browser

Verify

pnpm verify        # lint + typecheck + tests
cd src-tauri && cargo clippy --all-targets -- -D warnings && cargo test

Update your installed copy

TRACE is installed from an installer you build yourself. To update it, open PowerShell in the trace folder:

cd C:\Users\nfbco\Documents\GITHUB\TRACE\trace
pnpm update-app -Check   # what would an update bring? Changes nothing
pnpm update-app          # update

-Check fetches from GitHub and shows the version you have installed, the version on main, and the commits in between, then stops. Use it to decide whether an update is worth a few minutes.

pnpm update-app shows the same, then asks "Build now?" before doing anything slow. It pulls main, installs dependencies and builds; TRACE stays usable during the build. It then asks again before closing TRACE — closing it mid-meeting ends the recording — and opens the new installer. Add -Yes to skip both questions.

It stops with a clear message, and nothing installed, if there are uncommitted changes, the pull fails, or the build fails.

Last, it tidies the build folder, which Cargo otherwise lets grow without limit: installers from earlier builds are deleted, and so are the debug builds (src-tauri\target\debug) once they pass 20 GB. The release build is kept, so the next update only recompiles what changed.

pnpm open-installers opens the folder the installers are built into (src-tauri\target\release\bundle\nsis) and names the newest.

Optional: update from any folder

To type Update-Trace (and Update-Trace -Check) anywhere instead of changing folder first, add this to your PowerShell profile (notepad $PROFILE; create the file if it does not exist):

function Update-Trace {
    powershell.exe -NoProfile -ExecutionPolicy Bypass `
        -File "C:\Users\nfbco\Documents\GITHUB\TRACE\trace\scripts\update.ps1" @args
}

Then run . $PROFILE, or open a new terminal. If PowerShell refuses to load the profile ("running scripts is disabled on this system"), allow local scripts once with Set-ExecutionPolicy -Scope CurrentUser RemoteSigned.

Versions

Each release gets its own version, so installers and the running app can be told apart. The version appears in the app's status bar and on its About page, and names the installer (TRACE_0.2.0_x64-setup.exe).

pnpm bump            # 0.2.0 -> 0.2.1, for fixes
pnpm bump minor      # 0.2.0 -> 0.3.0, for features
pnpm bump 1.0.0      # an exact version

It updates package.json, src-tauri/tauri.conf.json, src-tauri/Cargo.toml, src-tauri/Cargo.lock and the banner above, and a test fails if any of them drift apart. Commit the bump with the change it ships.

In-app updates, like Handy's "Update available", are a later option: see the updater entry in docs/10-BACKLOG.md.
