Heivol Assistant

Q: What is Heivol Assistant?

A private personal AI agent that runs on its own dedicated virtual machine, built on Heivol's own home-built agent runtime (Customos). Unlike a generic chatbot, it comes wired into the heivol products you already use — your Heivol inbox, an auto-provisioned knowledge base in contextbox, your calendar, and your billing — with no per-tool setup. It can run shell commands and drive a real browser inside its own VM, and it is extensible with custom skills.

A private personal AI that’s genuinely yours. Your own isolated VM, your own API key, your own memory — never shared with other tenants, never mined for ads, never used to train anyone’s model. And it doesn’t start from scratch: it comes wired into the heivol products you already use — your inbox, your knowledge base, your calendar, your billing. One form, ~30 seconds, and you’re live on your own TLS subdomain. Built on Heivol Customos.

Start your test drive All products

One brain, one memory. Reach it from your Heivol inbox, the web, your desktop, or your phone — your own isolated VM on the other end.

How it works

Dedicated VM per tenant

Every customer gets a fully isolated virtual machine. No noisy neighbours, no shared memory, no cross-tenant data leaks. Your agent runs alone.

Wired into your heivol world

It isn’t a blank chatbot. At signup it’s auto-connected to your Heivol inbox, a private knowledge base in contextbox, your calendar, and your billing — no per-tool credentials, no wiring.

BYO or managed key, on your terms

Bring your own Anthropic API key and pay Anthropic directly (nothing to Heivol), or pick managed pay-as-you-go with hard per-tenant spend caps so you never get a surprise bill. Two lanes, no upsells.

Private subdomain over TLS

Each tenant gets a unique slug.assistant.heivol.com URL secured with TLS. No shared endpoints, no API gateway in between.

~30-second provisioning

Submit the signup form and watch a live progress stream as your VM is created, configured, and made reachable. The whole flow is automated end to end.

Zero-knowledge key handling

In BYO mode your API key is verified by making a single test call, then stored encrypted at rest. We never log, inspect, or proxy your key material.

Built on Heivol Customos

Customos is Heivol’s own home-built agent runtime — a single, focused agent loop with VM shell and browser access, a curated set of default skills, and first-class heivol integrations, rather than a generic assistant bolted onto your account.

What can your assistant do for you?

Heivol Assistant is a general-purpose personal AI agent that already knows about your heivol stuff. Here is a concrete, non-exhaustive taste of what people actually use it for.

Chat from your Heivol inbox

Your assistant sits pinned at the top of your Heivol inbox as its own conversation. Message it, drop files at it, or forward another message with “ask the assistant about this.” It can also reach back out to you unprompted.

Its own knowledge base

Every assistant gets a private contextbox knowledge base and can read your other KBs you allow. It remembers what you tell it, files things away, and can search across everything you’ve given it.

Reads and defends your calendar

Because it’s wired into your heivol calendar, it can move meetings, carve out deep-work blocks, chase RSVPs, and stop the back-to-back creep — without you granting yet another app calendar access.

Scheduled briefings & reminders

Native cron on the VM: “Every weekday at 07:30, pull my calendar, the weather, and the overnight GitHub notifications, then message me a one-paragraph brief.” Set it once, enjoy it forever.

Webhook & email-driven automations

Stripe charge came in? Sentry fired an alert? A new email landed via Gmail Pub/Sub? Expose a webhook or watch your inbox and the agent decides what to do — respond, escalate, log it, or ping you.

Browser & research errands

Tell it to price-check a flight, fetch a PDF and summarise it, watch a GitHub repo for releases, or cross-reference three articles into a one-page brief. It drives a real browser inside its VM.

Runs commands in its own VM

The assistant has a real shell in its isolated VM. It can run scripts, wrangle files, and carry out multi-step jobs — all sandboxed to your machine, never touching another tenant.

Coding help, growing over time

Read/Write/Edit/Grep tooling and a tested refactor loop over projects in its VM are rolling out beyond the beta, turning it into a credible “fix the bug” assistant for your own code — no separate dev box to rent.

Custom skills you can write yourself

The skills platform is extensible. Drop a folder of Markdown and scripts into your workspace and the agent picks it up. Teach it your weird niche: a tax regime, an API, a family recipe book.

A day in your life, with an assistant that lives on its own VM

Heivol Assistant is not a chatbot in a webpage. It is your assistant, running all the time, reachable from your inbox, the web, and your desktop, remembering what you told it last Tuesday. A few concrete examples of what regular people ask it to do:

Manage your calendar

“Move the dentist to next Tuesday afternoon, find an hour of deep work before my 10am, and stop booking back-to-back meetings on Fridays.” It reads, writes, and defends your heivol calendar — no extra app to grant access to.

Do the grocery shopping

On Monday you messaged “we’re out of olive oil and the kids finished the oat milk.” Saturday morning it has already built the shopping list, added the usual staples, and handed it off to your supermarket of choice — or sent it back to you to tweak before checkout.

Keep an eye on your stocks

“Ping me if NVDA drops more than 5 percent in a day, if my portfolio beta creeps above 1.3, or if any of my holdings issues earnings guidance.” Price feeds, news feeds, and your rules, running in the background.

Throw your own birthday party

“Invite these twelve people to my place on the 24th at 19:00, message them, track RSVPs, and nudge anyone who hasn’t replied by Friday.” It even remembers who’s gluten-free and who’s bringing the cake.

Book your next trip

“I want to be in Lisbon the weekend of the 18th, direct flight, budget under 4,000 kr, aisle seat. Hotel near Alfama, walkable breakfast places nearby.” It researches, shortlists options, and holds your hand through the final click — you approve the payment, always.

Never forget the important stuff

Your partner’s birthday, your parents’ anniversary, the dog’s vaccination, that one friend whose name you always forget. It remembers quietly in its own knowledge base, surfaces reminders with enough lead time, and can suggest a thoughtful gift based on what they actually talked about last time.

Plan the week’s meals

“Five dinners, one vegetarian, one fish, nothing with coriander, use up the chicken in the freezer.” Recipes, a shopping list, and a note pinned in your assistant thread so the family can actually read what’s for dinner tonight.

Triage your inbox

It reads the boring stuff so you don’t have to: summarises the newsletter, confirms the receipt, drafts the polite no, and flags the one email that actually needs your brain — straight into your Heivol inbox.

Track every package

Forward the confirmation email (or just let it watch your Gmail) and it handles the rest: courier websites, delay alerts, a heads-up when something’s out for delivery, and a nudge to file a claim if a parcel goes missing.

Watch your subscriptions and bills

“Tell me before anything over 200 kr auto-renews, and remind me to cancel the streaming trial on the 12th.” No more surprise charges, no more forgotten free trials turning into annual plans.

Keep you honest about habits

Morning check-in message, evening journaling prompt, a gentle nudge if you haven’t moved all day, a weekly summary you can actually look at. Your habits, your data, your VM — nobody else’s business.

Be your language tutor

Ten minutes of Danish practice over your morning coffee, corrected on the fly, with a flashcard deck that updates itself based on what you actually got wrong. Pick any language — it’s just a skill.

Meet Heivol Desktop

In preview

The VM assistant is always-on and isolated — perfect for a personal agent that lives in the cloud. But sometimes you want the agent right here, on the machine with your actual work on it. That’s Heivol Desktop: the same Heivol Assistant, running as a local engine on your own computer.

Your real machine in scope

Real repos, real files, your own git credentials — and no network hop on file operations. It’s the one thing the VM product deliberately can’t do, because there the isolation boundary is the whole point.

Same account, same wallet

Sign in with the same Heivol Identity and it draws on the same prepaid wallet and spend caps as your VM assistant. One bill, one identity, two places the agent can run.

The same skills, natively

It runs the very same agent and skills as the VM assistant — a heivol-themed chat surface over the same runtime, with durable local conversations you can list, reopen, rename, and delete.

Private by design

The engine binds to loopback only and is gated behind a per-launch token, so no other app or web page on your machine can drive it. Your local conversations stay on your disk, not in a shared store.

Not always-on — on purpose

Close the laptop and nothing runs. Scheduled jobs, background work, and push notifications stay with the always-on VM assistant. Desktop is for hands-on work at your keyboard, not for a 24/7 agent.

macOS first

Heivol Desktop is in preview on macOS today, with Windows and Linux to follow. It ships to Heivol Assistant subscribers as part of the beta — same account, no separate signup.

See it in action

Three real conversations, on three of the surfaces you can reach it on, with the same agent and the same memory. No screenshots from another product — these are rendered live so they work in dark mode, scale to your screen, and stay sharp on any display.

Pricing

The assistant is free to run — no platform fee, no VM fee. You pay only for the tokens you use, on a lane you pick. Heivol never marks up your compute silently and never bills you for tokens you didn't ask for.

Every plan includes

Free Your dedicated virtual machine, your subdomain, 24/7 reachability, and the Heivol Desktop app — at no charge. You only ever pay for token usage.

You bring your Anthropic API key
Tokens billed by Anthropic directly — Heivol adds nothing on top
Best if you already have Anthropic credits or an enterprise deal
Hard per-tenant circuit-breaker limits still apply to protect your key

Heivol manages the provider keys; you just use the assistant
Prepaid wallet — top up from 100 DKK, see every debit in real time
Set your own monthly spend cap — when you hit it, the assistant pauses until you raise it
Token pass-through at the provider's rate plus a small transparent margin to cover billing infrastructure

One wallet covers every surface — the VM assistant and the desktop app draw from the same balance. The billing ledger keeps every debit visible to you, down to the individual token request. You're only ever billed for the tokens you actually used.

Frequently asked questions

What is Heivol Assistant?

A private personal AI agent that runs on its own virtual machine, built on Heivol’s own home-built agent runtime (Customos). Unlike a generic chatbot, it comes wired into the heivol products you already use — your Heivol inbox, a private knowledge base in contextbox, your calendar, and your billing — with no per-tool setup. It can run shell commands and drive a real browser inside its own VM, and it’s extensible with custom skills.

How do I reach my assistant?

Four ways, one agent and one memory behind them all: as a pinned assistant conversation at the top of your Heivol inbox, from a direct chat page at assistant.heivol.com, from your phone, and from the Heivol Desktop app that runs the same agent as a local engine on your own machine.

What is Heivol Desktop?

A desktop app that runs the same Heivol Assistant agent as a local engine on your own computer instead of on a VM. Because it runs on your machine, it has your actual files, repositories, and git credentials in scope — with no network hop on file operations. It signs in with the same heivol account and draws on the same prepaid wallet as your VM assistant. It’s not always-on: close the laptop and nothing runs, so scheduled jobs, background work, and push notifications stay with the VM assistant. In preview on macOS, with Windows and Linux to follow.

Do I need to bring my own Anthropic API key?

No. Two lanes only: bring your own Anthropic key and pay Anthropic directly (nothing to Heivol), or pick managed pay-as-you-go where Heivol bills usage back with a hard per-tenant spend cap so there are no surprise bills.

Is my data shared with other tenants?

No. Every tenant gets a fully isolated virtual machine with its own memory, file system, and subdomain, plus its own private knowledge base in contextbox. There is no shared agent process, no shared cache, and no cross-tenant data path.

Can it run scheduled tasks and respond to events?

Yes — on the VM assistant. It has native cron, webhook, and Gmail Pub/Sub triggers, so it can check your calendar every morning, post a status update on a schedule, react when a specific email arrives, or respond to any HTTP callback. Because the VM is always on, this runs whether or not you’re at a screen. The desktop app isn’t always-on, so scheduled and background work stays VM-side.
