The Viktor alternative

An AI teammate, not an AI hire

Demi lives on your Mac, learns how you work, and gets things done for you, with your approval. Viktor is an autonomous AI hire you assign tasks to and oversee.

  • Context from across your work
  • Prepared before you ask
  • You approve the next step

One follow-up. Two very different asks.

You have just come off a 40-minute call. Here is what each one needs before it starts.

What you assign Viktor

A TASK, WRITTEN OUT

Write a follow-up to [their name and company] covering [what was discussed].

I promised [the thing, by the date]. Our pricing is [look it up]. Tone: professional but friendly.

Then check what it sent.

Briefed, then supervised It runs on its own once you let go.

What Demi already started

BEFORE YOU ASKED

Nothing to assign. It was already on it.

Demi has the account and the contact, what you committed to on the call, the pricing from the deal record, and how you write to this account.

Drafted, and waiting on your yes Nothing sends until you approve it.

Steps you stop taking

Every one of these is work you do before an assigned task can even begin.

4 of 5

steps in briefing and checking an AI hire that Demi removes entirely.

  1. 1Notice the follow-up is owed
  2. 2Write the brief, with the context pasted in
  3. 3Wait for it to run
  4. 4Check what it did on its own
  5. 5Read it and approveStill yours

Counted from the process above, not from a benchmark.

Already in motion

It's already on it

Demi surfaces the next step before you ask: the reply you owe, the follow-up you promised, the thread that went quiet. Viktor waits to be assigned.

You stay in control

Demi drafts the email, books the meeting, updates the CRM, then waits. Nothing happens until you approve it. Viktor executes on its own, so oversight is your job.

Demi vs Viktor
questions

  • For most teams, a better one. Viktor is an autonomous AI hire you assign tasks to and then supervise. Demi is an AI teammate that lives on your Mac, learns how you work, surfaces the next step before you ask, and acts only once you approve. If you want work finished rather than delegated, Demi is the stronger fit.

  • There is nothing to migrate. Download Demi for Mac, connect your tools in a couple of clicks, and it starts learning from the work you already have. Most people are approving their first drafts the same day, and you can keep Viktor running while you try it.

  • Three things. It lives on your Mac across every app and screen rather than only in Slack and Teams. It learns your voice, your priorities and how you handle each account, where Viktor is generic on day one and on day ninety. And it is shared with the team in Slack and personal on every Mac, rather than one shared hire everybody calls.

  • Yes, because there is nothing to manage. Viktor is an autonomous employee you oversee: you brief it, it runs, and you check what it did. Demi is a download. No AI hire, no infrastructure, and no supervision model to agree on before anyone can start.

  • No, by design. Demi prepares the work and stops. Nothing sends, commits, or changes a system of record until you approve it, so a consequential action is always yours to make. Viktor executes on its own, which is why oversight becomes your job.

  • Yes. Demi builds routines by watching the repetitive work you actually do, rather than waiting for you to configure them. Viktor builds autonomously in an engineering style, which is powerful and a different thing: one takes work off your plate, the other needs a brief.

  • Yes, and this is where the gap is widest. Demi drafts replies in your voice from the thread and the call behind it, updates the deal record from what was said, and flags the thread that went quiet. Viktor produces task-driven output against a brief you wrote.

  • Demi connects across Gmail, Calendar, CRM, Slack and 100+ tools. Viktor advertises 3,200+, which is genuinely more. The question worth asking is whether breadth or context matters for your work: Demi reads across the tools you actually use and carries what it learns between them.

  • Demi has a free plan with up to $50 in credits and no card required, and individual plans from $25 a month with credits included. Viktor is usage-based from $50/mo.

  • Yes. Some teams keep an autonomous tool for engineering-style automation and give every person Demi as their AI teammate on their Mac. They solve different problems.

  • Yes. Demi is SOC 2 Type II compliant, assessed at CASA Tier II, and is a Google-verified app. It uses AI vendors on zero-retention terms, so your data is never used to train models, and you can have it deleted within 24 hours by emailing privacy@demi.ai.

  • Yes. Gmail, Outlook, Google Calendar, Slack, HubSpot, Salesforce, Attio, Close, Gong, Granola, Notion, Linear, Google Drive, Zoom and 100+ more. Demi carries context between them, so what it learns in one shows up in the next without you moving it.

  • Demi has a free plan rather than a trial. Download it for Mac with no card required, and new accounts get up to $50 in credits. Paid individual plans start at $25 a month with credits included, and you can add more any time.

Where Viktor slows you down

  • It isn't where you work

    Viktor runs in Slack and Teams. It isn't there in the apps and screens where the rest of your day actually happens.

  • It waits to be told

    You tag it and explain the task every time. Nothing is teed up before you think to ask for it.

  • Shared, with nothing personal

    The whole team calls the same generic AI hire. No version of it is yours, holding your context and your voice.
