Verkko Halo · for people

The assistant that remembers.

Halo learns what you teach it and keeps it. It wakes up knowing your day, drafts replies that already sound like you, and puts agents to work on the jobs you'd rather not do. Nothing is sent, booked or scheduled without your OK.

Home

Wakes up knowing your day.

Open Halo and your brief is already written: what you're focused on, what's next and who's waiting, and what it learned since yesterday. Meeting prep is ready before you ask, with chat one line below.

  • Focus, Next and Mind: your day in three lines
  • Meeting prep drafted from your email and past calls
  • To-dos pulled from your email and calendar, inbox ranked by who needs you
Near you

When the day is yours, it knows that too.

Built around your calendar, your location and the time of day: what's free, and what's nearby worth doing.

  • Your week at a glance, with one-tap "Plan today"
  • Places nearby, filtered for dinner, a walk or a work spot
  • Ideas that change with the hour
My agents

Say what should get done. Agents do it.

"Organise my trip to Milan next week." Halo puts a crew of agents on it, using your calendar and what it knows about you, and reports back with the outcome, ready for your approval.

  • One-tap jobs: prep my week, clear my inbox, brief my next meeting
  • Every run kept, with its outcome and the tools it used
  • Nothing sent, booked or scheduled without your OK
For You

Your day as it actually is.

What's on and what's worth doing around you, on a list or a map. Plan a whole day in one sentence, like "what can I do in London 18–20 Sept?", and fit events straight into your week.

  • Plan my day, by date, with directions
  • Local news and events, ready to add to your calendar
  • Alternatives if the first pick doesn't suit
Memory
Same question. One of them remembers.

Most assistants start from zero every conversation, or paste old notes back into the prompt. Halo is conditioned on what it has actually learned about you. The gap between the two answers is the product.

Base language model · no memory
"Draft the follow-up to this morning's call."
"Sure! Could you tell me who the call was with, what was discussed and what tone you'd like?"
Halo · conditioned on Voltaic memory
"Draft the follow-up to this morning's call."
"Here's a reply to Priya at Northwind: the 200-seat pricing you promised, the pilot dates you agreed, signed off the way you usually do. Send it?"
01

Read like a human

Add documents, spreadsheets, PDFs, code or a folder. Halo reads each one passage by passage and replays earlier knowledge so it never forgets.

02

Teach a fact

Tell it something new and it's written into the model, not a sticky note. You can watch how much of the new fact it picked up and how much it kept.

03

Projects with their own memory

A shared home for one piece of work. Inside a project, Halo answers only from what the project has been told, never from anyone's private knowledge.

Verkko technology · Voltaic
A model that keeps learning, and doesn't forget.

Halo runs on Voltaic, Verkko's spiking neural network built for continual learning. Ordinary networks overwrite old knowledge when they learn something new. Voltaic was designed from our lab's research so that it doesn't.

Continual learning

Learns while you use it

It learns at inference time, from your conversations and documents, without a retraining cycle.

Metaplasticity

Protects what it knows

Connections that matter become harder to overwrite. Teach a sequence of facts and the earlier ones stay recallable.

Spiking core

355M to 7B parameters

Event-driven neurons fire only when there's something to say, which keeps learning efficient enough to run per person.
