vezir 0.8.13

Internal scribe service that wraps meetscribe for team-scale meeting capture, transcription, summarization, and speaker labeling

Self-hosted team intelligence. Record a meeting on any device; Vezir gives you back a diarized transcript, an AI summary, and a PDF — processed on your own GPU server and synced into a private team archive you control. Sign in with Nostr or Google.

Vezir wraps millet (the transcription/diarization/summarization pipeline) and turns it into a multi-user, multi-team service: a scribe records on their laptop or phone, the audio uploads to a central GPU box, and the team gets back labeled transcripts and summaries — with speakers resolved to GitHub handles.

Status

Alpha (0.8.3). Built for small teams that want meeting audio to stay inside their own infrastructure: one GPU server (Linux/CUDA or Apple Silicon) reachable over ordinary HTTPS. Full history in CHANGELOG.md.

What's new in 0.7–0.8:

• Identity sign-in (0.8.x). Members sign in with Nostr (a remote signer like Amber via NIP-46, or the NIP-55 Android intent flow) or with Google (@workspace-domain accounts via the OAuth device grant). The server mints a short-lived session JWT (~24h); no key or password touches the client. vzr_ bearer tokens are retained for machine/CI use.
• Public-access front (0.8.x). A small VPS terminates nothing — it WireGuard-forwards TLS to the server, which keeps the cert. Clients reach the server over plain outbound HTTPS, so it works from CGNAT / IPv6-only links (e.g. Starlink) with no per-client VPN.
• Multi-team by membership (0.7.0). A token/identity is a person, not a team; team scope is supplied per-request via X-Team-Id and validated against a memberships table. One identity covers every team you're in; the TUI/Android auto-discover them. Team keys are stable UUIDs with mutable slugs (vezir team rename).
• Hardening (0.8.2). NIP-98 replay protection, header-injection-resistant login-URL pinning (VEZIR_PUBLIC_URL), exact Google-domain matching.
• Resumable uploads (tus.io subset), vezir relabel, vezir pull, per-team voiceprints + sync, vezir doctor.

The JSON-only API (no web dashboard since 0.7.0) is consumed by the TUI, the Android app, and the CLI. Speaker labeling happens in the TUI/Android or via a one-time /login?code=… page link printed after upload.

Linux and macOS (Apple Silicon) laptop clients and an Android client are supported.

Requires millet-pipeline >= 0.12.5 (pinned via the [server] extra).

Sign-in & access

Members authenticate with their own identity; an admin authorizes it once.

# Admin, on the server — authorize an identity (one of):
vezir npub add   --npub npub1…             --github <handle> --label "<who>"
vezir google add --email [e-mail] --github <handle> --label "<who>"
# …and grant team scope (one handle covers every team they join):
vezir team add-member --team <slug> --role scribe --github <handle>

# Member, on their laptop:
export VEZIR_URL=https://your-vezir-host
vezir login --team <slug>                  # Nostr (remote signer / Amber)
vezir login --method google --team <slug>  # Google (@workspace-domain)

vezir login stores a ~24h session; the client uses it as Authorization: Bearer on every request. Re-run to refresh.

Production note: set VEZIR_PUBLIC_URL=https://your-host on the server so NIP-98 login-URL verification is pinned to a fixed base (not reconstructed from request headers).

Millet runs as an unmodified subprocess via a per-job HOME shim that exposes per-team voiceprints + sync config. Vezir owns the job queue, per-team voiceprint DBs, team roster/memberships, and auth.

Clients

Client	Best for	Install
vezir tui	Day-to-day desktop use — record, browse sessions, read transcripts/summaries, label speakers, all in one terminal UI. ctrl+e Teams tab, ctrl+t cycles teams.	pip install 'vezir[tui]'
vezir scribe	Headless / ssh / scripted recording. Pause-resume with p.	pip install vezir
vezir upload <file>	An existing WAV/OGG (phone, OBS, etc.); resumable.	pip install vezir
vezir pull	Download artifacts for meetings others recorded (team sharing without git).	pip install vezir
vezir-android	Recording from a phone; signs in with Nostr (Amber) or Google.	Sideload the release APK

All desktop clients resolve credentials from a vezir login session (stored per-team in ~/.config/vezir/teams.json), or from VEZIR_URL+VEZIR_TOKEN for machine/CI. The TUI/Android auto-discover every team you belong to from /api/me.

Summarization presets

The client sends a preset id as the summary_preset form field; the worker passes it to millet transcribe --summary-preset <id>.

Preset	Backend	Model	Use case
high-quality	claudemax	Sonnet	Default on desktop; highest quality (Claude Max on the server).
confidential	tinfoil	DeepSeek (TEE)	Hardware-attested enclave — prompts not visible to the provider. Default on Android; PDF gets a CONFIDENTIAL watermark.
alternative	openrouter	Kimi	Cheapest cloud option.

When a preset is explicitly chosen the server does not silently fall back to another backend on failure — a silent tinfoil→cloud fallback would defeat the Confidential preset. Set via vezir scribe --preset … or the TUI/Android dropdown.

Privacy toggles (per upload)

Toggle	Default	When set	Sticky?
auto_label	ON	OFF skips voiceprint matching; routes to manual labeling.	Yes
sync	ON	OFF keeps the session on the server (local-only), not pushed to the team git repo. Retroactively syncable.	Yes
personal	OFF	ON marks it private to you and forces sync off for this recording.	No (per-recording)

CLI: --auto-label/--no-auto-label, --sync/--no-sync, --personal on scribe and upload. Server-side kill switches: VEZIR_SKIP_SYNC=1 (global sync off), VEZIR_DELETE_AUDIO=1 (drop audio after artifacts).

Install profiles

Role	Install	Footprint
Scribe client (CLI)	pip install --user vezir	~30 MB
Scribe client + TUI (recommended desktop)	pip install --user 'vezir[tui]'	~35 MB
Server (FastAPI + worker + pipeline)	pip install --user 'vezir[server]'	~3 GB (Linux/CUDA: whisperx+torch+pyannote); +mlx-whisper on Apple Silicon

The base install uses millet-record (capture only); [server] adds millet-pipeline for transcription/diarization/summarization (plus mlx-whisper on Apple Silicon via a PEP 508 marker for the MLX ASR backend).

Quick start — server

git clone https://github.com/pretyflaco/vezir.git && cd vezir
pip install --user -e '.[server]'

mkdir -p ~/vezir-data
vezir voiceprints seed --from ~/.config/meet/speaker_profiles.json   # optional

vezir team create --id myteam --name "My Team"
vezir team set-sync --id myteam --remote https://github.com/yourorg/meetings.git  # optional

# Authorize yourself + grant scope (identity sign-in):
vezir npub add --npub npub1… --github you --admin --label "laptop"
vezir team add-member --team myteam --role admin --github you

export VEZIR_PUBLIC_URL=https://your-vezir-host   # recommended in prod
vezir serve                                       # binds 127.0.0.1:8000; front with Caddy

TLS via Caddy

cd infra/caddy && ./install-caddy.sh
# edit the Caddyfile for your hostnames, then:
sudo systemctl enable --now caddy

For a public-access deployment (clients on any network, incl. CGNAT), see infra/vps/ — a VPS WireGuard-forwards :443 to the server, which terminates TLS (the VPS sees only ciphertext).

Quick start — scribe client

pip install --user 'vezir[tui]'
export VEZIR_URL=https://your-vezir-host

vezir login --team myteam                 # Nostr / Amber
# or: vezir login --method google --team myteam

vezir tui                                 # record + browse + label
vezir scribe --title "team sync"          # CLI record (p = pause; Ctrl+C = stop)
vezir upload ./recording.ogg --title "…"  # existing file (resumable)
vezir pull                                # artifacts for meetings others recorded
vezir doctor                              # diagnose creds / connectivity / certs

After upload, artifacts (summary, transcript, PDF) auto-download into ~/vezir-meetings/<team>/meeting-…/. Standalone uploads accept .wav/.ogg.

macOS (Apple Silicon) scribe

pip install vezir pulls millet-record, whose macOS wheel ships a Swift sidecar that captures mic + system audio via native APIs (no virtual drivers). Grant both Microphone and System Audio Recording to your terminal app; verify with millet check. The server does the heavy lifting.

Environment variables

Variable	Default	Effect
VEZIR_DATA	~/vezir-data	All server runtime state.
VEZIR_HOST / VEZIR_PORT	127.0.0.1 / 8000	Bind for vezir serve (front with Caddy).
VEZIR_PUBLIC_URL	unset	Canonical public base URL; pins NIP-98 login-URL verification (recommended in prod).
VEZIR_URL	http://localhost:8000	Server URL for clients.
VEZIR_TOKEN	—	vzr_ bearer for machine/CI clients (interactive members use vezir login).
VEZIR_GOOGLE_CLIENT_ID / …_SECRET[_FILE] / …_ALLOWED_DOMAIN	unset	Enable Google sign-in (server holds the secret).
SSL_CERT_FILE / VEZIR_CADDY_ROOT_CERT_PATH	unset	Extra internal CA to trust; the client appends it to the public store (0.8.0+), so public + internal hosts both validate.
VEZIR_COOKIE_SECURE	unset	1 adds Secure to the session cookie (HTTPS).
VEZIR_SUMMARY_PRESET	unset	Default preset (high-quality|confidential|alternative).
VEZIR_RECORD_DIR	~/vezir-meetings	Local recordings root.
VEZIR_MILLET_*	auto	Pass-throughs to millet transcribe (device, compute type, ASR backend, MLX model).
VEZIR_SKIP_SYNC / VEZIR_DELETE_AUDIO	unset	Server-side sync kill switch / audio retention.
VEZIR_MAX_UPLOAD_BYTES	2147483648	Max upload (2 GiB → 413).
VEZIR_DISABLE_RATELIMIT	unset	Disable the in-process rate limiter. Test/CI only (logs a loud warning if set).

Performance (rough, 1h audio)

Runtime	Path	Time
NVIDIA CUDA	CUDA float16	~5–20 min
Apple Silicon (MLX)	MLX Whisper + MPS	~10–30 min
Apple Silicon (split)	CPU CTranslate2 + MPS	~20–45 min
CPU only	CPU int8	~1.5–10 h

Runtime dirs are created 0700, sensitive files 0600; the systemd unit sets UMask=0077.
