Heart rate
Every 1–3 sRemote photoplethysmography (rPPG) tracks the tiny colour changes in your face as blood moves, frame by frame — using light your webcam already collects.

OBS plugin · camera only
Your body is part of the stream.
StreamEmote reads your heart rate, breathing and heart rate variability from the webcam you already own — and puts them on screen in real time. No chest strap, no smartwatch, no second device.

Signals
Three vitals, zero hardware.
Your camera already sees more than you think. Skin brightens and dims with every heartbeat — too faintly for you to notice, plenty for a 30 fps camera.
Breathing rate
About every 10 sEstimated from the same camera picture. No strap, no mic, no calibration breath to hold.

Stress
Coming soonHeart rate variability — the variation in the gap between beats, which shrinks when you're under load — is measured today and shown as RMSSD in milliseconds. A Low, Moderate or High stress state derived from it is coming soon.

Privacy
Your frames are never stored.
A plugin that reads your pulse off your face should have to explain itself. So: while the source is connected, frames travel from OBS over an encrypted connection to our inference service, which analyses them in memory and discards them. We keep the numbers, never the picture.
- No video stored, everFrames are processed in memory and dropped. Nothing is written to disk.
- Only numbers come backHeart rate, breathing, HRV and a signal-quality flag. That's what reaches your overlay, and what your history keeps.
- Encrypted, and only while connectedFrames go over HTTPS (TLS) and only while the StreamEmote source is connected. Disconnect it in OBS and nothing is sent.
- Your data, your callExport everything or delete your health data from Settings. The details are on the privacy page.

Setup
Four steps, one stream to spare.
No calibration routine, no warm-up window, no baseline session before you can go live.
- Step 01
Install the plugin
An installer for Windows 10+ or a package for macOS 12+. It adds a StreamEmote Vitals source to OBS — no manual folder surgery.
- Step 02
Point your webcam
Any camera OBS can already see. StreamEmote reads the same feed your viewers do, so there's no second device to frame.
- Step 03
Sign in and connect
In the source's properties, click Sign in with browser, confirm your free account, then click Connect.
- Step 04
Go live
Vitals appear on the overlay once the signal settles, and your live dashboard follows along.
ReactionsComing soon
When you snap, the stream feels it.
StreamEmote will watch your expression and your pulse together. An emote only fires when both agree — so the rage is real rage, not a well-timed eyebrow.
Mode_CALM
Calm
A cool aura settles in as your breathing slows. Useful when you're actually trying to show your audience what calm looks like.
68 BPM12 BR/MINLOW
Mode_CLUTCH
Clutch
Heart climbing, breath tightening, stress stepping to Moderate. Chat can see the 1v5 landing before you say a word.
126 BPM21 BR/MINMODERATE
Mode_RAGE
Rage
Peak heart rate plus a rage face triggers the tint and the emote burst together. Movement also drops signal quality — and the overlay says so.

Two ways to renderA light overlay layer over your cam, or a full face warp through StreamEmote's virtual camera. Both are coming soon.
On stream
More than a number in the corner.
Once your vitals are a live signal, the rest of your scene can listen to them. These are next on the list.
- Clutch alerts Coming soonCross a heart-rate threshold and fire a screen shake, a sound, or a lower-third banner. The moment announces itself.
- Auto-highlight clips Coming soonEvery heart-rate spike gets timestamped and clipped. Your VOD editor opens to a list instead of six hours of footage.
- Heart-rate donations Coming soonViewers tip to set a challenge — hit 150 bpm, or hold Low stress for five minutes — and watch your vitals answer.
- Merged co-stream vitals Coming soonRun a duo or a squad and put everyone's heart rate in one panel. The spike that matters is usually someone else's.
Honest by default
When the signal is bad, we say so.
Dim lighting, a turned head, a lean out of frame — rPPG degrades, and a plugin that kept printing a confident 72 would be lying to your chat. StreamEmote shows its confidence instead, and drops the number rather than invent one.

After the stream
Every session ends with a stat card.
Peak and average heart rate, average breathing, your calmest minute and the signal quality. Share a link and the card shows up as the preview on X or Discord, while chat is still in the mood to argue about it.
