Evopien / A new presence / 5 November 2026
It moves towards you. It keeps the thread. It has something to show.
The head turns towards a face. A visual watch notices the change you asked for. A spoken counter keeps tally while the interaction continues. A question brings current information from the web into the conversation. Evopien is becoming a much more tangible presence.
Our new English and Spanish videos show the live interaction. Alongside that physical build, governed-memory testing has reached 98 simulated days and 2,200 staged interactions. This chapter brings the achievements together: local voice and vision, a moving head, useful tasks and memory that can change with its owner.

Measured progress / recorded development runs
The numbers behind the new presence.
- Median voice onset
- 1.35 sSpeech end → first generated audio · 11 recorded non-camera onsets.
- With video enabled
- 1.58–1.88 sSpeech end → first answer audio · four EN/ES replay examples.
- Public-web answers
- ≈1.6 sRecorded answer retrievals: 1.575–1.653 seconds.
- Governed-memory timeline
- 98 daysSimulated days · 2,200 staged synthetic interactions.
- Latest memory week
- 129/129Complete answers reviewed, with 129 matching state checks.
- Physical face following
- 10+ min637.5 seconds recorded in the saved head session.
These snapshots come from separately recorded development runs. Voice onset marks generated audio; camera-on figures use generated scene input in a local replay. Web timing measures answer retrieval. Memory follows a simulated chronology; head duration comes from the attended physical session.
01 / Nearly 100 simulated days
A memory milestone with real depth.
98 simulated days. Fourteen weeks on a changing test timeline. 2,200 staged synthetic interactions. Evopien’s governed-memory campaign has moved through saved preferences, corrections, changes of mind, selective forgetting and restarts in English and Spanish.
The achievement is in what happens next. A later answer must follow the current preference, including its conditions and reasons. A one-off exception belongs to that request. A correction changes what is current. A memory the owner has removed stops shaping later retrieval.
The latest weekly block delivered 129 out of 129 reviewed complete answers, alongside all 129 corresponding memory-state checks. In that run, 118 text responses completed within five seconds. The memory campaign and the new physical demo are distinct recorded milestones, advancing the same ambition: a companion that stays useful as life changes.
02 / From design to movement
The head we imagined is now on the desk. And it moves.
Evopien now turns and tilts its physical head to follow a face during our live sessions. The camera, display, printed enclosure and neck form one visible point of interaction. A glance has a direction. A spoken answer has a place.
The saved head session recorded 637.5 seconds—more than ten minutes—of physical following activity, with face reacquisition exercised within the session. This is the moment the build became something you can meet across a desk.


03 / Give the conversation a task
Watch for a change. Count a word. Keep the conversation moving.
Visual watches let you ask Evopien to look out for a requested change and tell you when it appears. Spoken keyword counters keep track of chosen words, report running totals and accept cancellation by voice. Multiple counters bring more than one small task into the same session.
These capabilities change the rhythm of the interaction. You can set something in motion, continue talking and return to the result. The saved physical run delivered five watch notices; a separate bilingual counter replay delivered sixteen spoken count updates across four cases.

04 / Capability on the device
Local voice. Local vision. A quicker route to the outside world.
Listening, speech, visual understanding, governed memory, face tracking and head control run on our own hardware. That local foundation gives the project its character: intelligence close to the person, with a physical presence in the room.
Recent local development measurements recorded a 1.35-second median from speech end to first generated audio across eleven non-camera onsets. A separate video-enabled bilingual replay recorded first answer audio between 1.58 and 1.88 seconds across four examples.
For current information, recorded public-web answer retrievals completed in 1.575–1.653 seconds, with first text appearing in roughly 1.3 seconds. Weather, news and practical research can join the interaction while the local voice, vision and physical control stay on the device.
05 / Since the last journal
Three weeks. A much more complete picture.
The last journal was dated 16 October. Through the rest of that month, live audio and camera work gained visual watches, spoken counters and richer scene interaction. In early November, those capabilities came together with bilingual conversation and quicker web research. On 5 November, we saved the new physical-head demo checkpoint.
Alongside the 98-day memory milestone, the build now has a new sense of scale: more it can do, more you can see, and a real head moving on the workbench. The videos are the invitation. Come and see how far Evopien has travelled.
