让气味成为世界的另一种语言
Scent isthe next medium.
Sight and sound became data.
Smell never did.
A photo can be taken, saved, sent and shown on any screen. A song can be recorded and played on any speaker. A smell still disappears the moment you leave the room. TRACE is building the missing chain.
Long-term vision. Today TRACE has a working AI Diffuser prototype and AI NOSE experiments — every capability on this site carries its development status.

如果思念有气味,你会寄给谁?
If longing had a scent, who would you send it to?
Capture. Create.Store. Play.
Four products, designed as one loop. A smell is recorded or described, turned into a blend, saved as a record, and reproduced on a compatible device — then the person who smells it tells the system how close it came.
Concept renderSix ingredients.One saved blend.
The AI Diffuser holds six aroma ingredient bottles and mixes them in different proportions, so one device can play many scents — and play a saved version again the same way. Replace one bottle or a whole set.
The diffuser holds six aroma ingredients and mixes them in different proportions. Move a channel to change the blend.
Illustrative Example palette for this demo. TRACE’s production ingredient set is still being defined.

Say how itshould feel.
Most people cannot name fragrance notes, but they know what they want: “a summer beach, a little less sweet”. TRACE’s AI turns those words into a draft blend, and every round of feedback becomes the next version.
Concept simulation A keyword sketch of the interaction, running in your browser. It is not TRACE’s AI model and does not produce real formulas.
A smell,written down.
A separate sampling machine. A sample goes into a closed chamber; a gas-sensor array records its response pattern together with time, temperature, humidity and blank and reference readings.
- 01
Sensor fingerprint
The response pattern of the sensor array — the raw material for recognising a scent again.
- 02
Sampling conditions
Everything needed to compare one reading with the next, on another day or another device.
- 03
Human description
The words of the person who smelled it, stored with the reading.
Today: firmware compiled for a five-essential-oil test set and software tested on synthetic data. Recognition of physical samples is the next milestone.
Every version,kept.
A scent record holds where a scent came from, every version that was smelled, the ingredients a device needs to play it, and who is allowed to. Send it as a Scent Card. Formulas stay private; recipients get playback rights.

Digital scent has been promised before. We would rather show our working: what exists, what is being built, and what still has to be proven.
