让气味成为世界的另一种语言

TRACE 万析 · Scent technology

Scent isthe next medium.

We are building the hardware and AI to capture a smell, describe it as data, and play it back in another room.

01 — The missing format

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?

02 — One system

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.

01CaptureAI NOSE

Record a real-world smell as data.

Experimental
02CreateAI Scent Creation

Describe a feeling. Smell a draft. Refine it.

03Store & shareTRACE Scent Cloud

A scent record that can be saved, versioned and shared.

04PlayAI Diffuser

Six aroma ingredients, mixed on demand.

Prototype built
03 — AI DiffuserPrototype built

Six 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.

Try a saved blend

The diffuser holds six aroma ingredients and mixes them in different proportions. Move a channel to change the blend.

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.

05 — The TRACE appPrototype built

The whole system,in your hand.

The companion app is where people meet TRACE every day: describe a scent in Scent Studio, keep every formula and concept, and start, stop or adjust what the diffuser is playing.

  • 01

    Scent Studio

    Describe the scent you imagine, set the tone — regal, warm, fresh — and create a concept.

  • 02

    Your scents

    Every concept and formula you have made, ready to refine or play again.

  • 03

    Control center

    See what is diffusing, how far along it is, and take over at any time.

App prototype, shown running against a virtual device. Interface and names may change before release.

AI NOSE with its sample drawer open — concept renderAI NOSE · concept render, not a manufacturing drawing
06 — AI NOSEExperimental

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.

07 — TRACE Scent CloudPlanned

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.

08 — Why now

People already payfor how things smell.

Context, not TRACE’s addressable market.

US$2.1bn

Global aroma-diffuser market in 2025, forecast to grow 8.6% a year to 2033.

09 — Where we are

Ambitious about the future.Precise about today.

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.
