Armbrain vs Viktor
Viktor is an AI worker in Slack and Teams that does the jobs you give it. Armbrain collects each client's data, keeps it in that client's own mind, and has your briefing ready each weekday morning. For fractional CMOs running several clients.
Short answer: Viktor is good at doing tasks. It connects to your tools, builds reports and decks, and runs scheduled jobs you approve. But its memory is shared across your whole workspace, and its own agencies page says clients do not get an automatically separate context today. So keeping clients apart, and setting up what runs for each one, stays with you. Armbrain connects to your tools once, then collects each client's meetings, email, calendar, files and CRM on its own, sorts them into that client's mind, and works overnight so your briefing is ready when you start.
Same Monday, two ways
You run six clients. Three have calls today. Here is how the morning goes.
With Viktor in Slack
- 7:40. The ad spend recap you set up and approved last month is waiting in the channel. That part works.
- Ask Viktor about your first client. Its memory is shared across the whole workspace, so you name the client and the account you mean.
- Ask what you promised this client last week. A running promise list is not a stated feature, so you ask Viktor to dig through the thread, then check your own notes.
- You want a weekly check on a second client too. Viktor drafts the job, and it stays paused until you read it and approve it.
- Do it again for the second client. Then the third.
- 8:55. Your first call starts in five minutes.
With Armbrain
- Overnight, Armbrain pulled in last week’s call transcripts, new email threads, calendar changes and updated files, and sorted each one under the right client.
- 6:00. Your morning briefing is waiting in your inbox, Slack or HQ dashboard: today’s meetings, what came in, and what needs you.
- Two promises have gone past due. Your HQ dashboard puts them at the top of the list.
- Ask for today’s prep and all three calls come back in one brief: who is in the room, open promises, recent decisions.
- Ask for Friday’s follow-ups and get drafts in your voice to review.
- 7:40. Coffee. Read. Done.
The briefing time is a default you can change. Briefing sections need the matching tool connected (email, Slack or calendar). Whole-day prep needs Google Calendar connected. Viktor details come from Viktor's own product and agencies pages, linked below.

- Runs the businessEOS rocks, issues, scorecards, sprints, L10 prep, quarterly reviews, a brand book and handoffs for each client.
Side by side
| What matters | Armbrain | Viktor |
|---|---|---|
| Who collects your client data | Armbrain does, after a one-time connection for each tool. Meetings: Granola, Fireflies, Fathom, Zoom, Teams. Email and files: Gmail, Outlook, Google Drive, Dropbox, OneDrive, Notion. Calendar: Google Calendar (through your Google sign-in) and Outlook. CRM and projects: HubSpot, GoHighLevel, Pipedrive, Asana, ClickUp and more. Marketing numbers: Google Analytics, Mailchimp, Klaviyo, ActiveCampaign. No pasting. | Viktor does, once you connect a tool. “Most are one-click OAuth, some use API keys”[6]. It also learns from chat: “Viktor reads conversations in channels he joins, observes workflows, and builds a knowledge base over time.”[1] |
| Keeping it current | Each tool is re-checked on a schedule, for example Gmail about every 7 minutes and Granola about every 15 minutes, so each client’s brain updates itself as new meetings and email land. | Its pages describe pulling numbers as part of a job. For a client report, “Viktor pulls paid performance and revenue from the connected accounts”, and it “keeps persistent context so recurring jobs do not restart from zero.”[4] Refreshing its stored memory on its own between jobs is not a stated feature on the pages we checked. |
| Sorting it by client | Each client gets its own mind. Email is routed to the right client within minutes. Notion pages go to the client you pick once. Anything Armbrain is unsure about waits in a review queue for you. | Asked if each client gets an automatically isolated context, Viktor's agencies page answers “Not today.” It “supports labeled connections and connection-level access restrictions” and says “Talk to the team if strict client separation is required.”[4] |
| Work done while you sleep | Works overnight so your briefing is ready when you start. It flags overdue commitments. Your morning briefing arrives on weekdays at 6:00 your time by default, plus an end-of-day wrap, a Friday scorecard and a Monday sprint kickoff. You do not set up a job for any of it. | A real strength. It “Runs scheduled jobs and long async tasks, and follows up on its own.”[5] Each new job starts paused: “he proposes a scheduled task in Slack and leaves it paused. Nothing runs until someone on your team reads it and approves.”[2] “Scheduled automations run on credits too.”[3] With six clients, you decide, approve and pay for what runs for each one. |
| What it remembers | Decisions, promises, people and history from your meetings, email, files and CRM, kept per client. | “the memory is shared across the team.”[2] “Viktor currently operates at the workspace level. All team members on a plan share the same Viktor instance and context.”[1] What it learns about a job becomes a skill, “a written procedure you can open and correct.”[2] |
| Finished work | Quarterly planning and review decks, and follow-up drafts in your voice when you ask. It does not build dashboards or apps. | A real strength. It “ships finished work like reports, dashboards, apps, and campaigns”[5]. For agencies: “Client reports, campaign audits, and decks.”[4] |
| Meeting prep | Ask for prep and get a brief with open commitments, recent decisions and who is in the room. Or ask for the whole day’s prep once Google Calendar is connected. A brief only uses what is stored. | Not a stated feature on the pages we checked. |
| Promises and follow-up | Commitments from meetings and email are pulled out automatically and stay on a list until they are done. Extraction is automatic but not perfect. Ask for a follow-up and Armbrain drafts it in your voice for your review. | Its home page lists “Meeting Follow-ups” among example jobs[1]. A running list of your promises to each client is not a stated feature on the pages we checked. Client-facing sends can wait for you: “Your account manager controls the final send.”[4] |
| Overdue items and quiet clients | Overdue commitments show up in your meeting prep and on your HQ dashboard. A weekly client health read on Thursdays flags clients who have gone quiet. | Not a stated feature on the pages we checked. |
| Running the work (EOS) | Built-in EOS tools: rocks, issues, scorecards, two-week sprints, L10 meeting prep, and quarterly planning and review decks. | Not a stated feature on the pages we checked. |
| Brand book | A brand book for each client. Armbrain suggests lines from your notes, and you confirm, edit or reject them. | A brand book for each client is not a stated feature on the pages we checked. Viktor says its skills help it “return work that is on brand and ready to use out of the gate”[5]. |
| Handing a client off | Package a client mind for a handoff, or export it. Drafting a handoff does not send it or grant access. | Not a stated feature on the pages we checked. |
| Setup | About 30 minutes. Many tools sign in with your account. Some need a key pasted once. | “Onboard in minutes”[3]. “The first job usually happens the day you add him.”[2] |
| Where it works | Inside Claude (claude.ai, Claude Desktop and Claude Code), plus the HQ dashboard in your browser for review, tasks, drafts and tool setup. Briefings can also go to email or Slack. | “Slack and Microsoft Teams have the full experience, approvals included. The web and desktop apps carry the same Viktor for work that starts outside chat.”[2] |
| Price | Personal mind free. $90 per person/month, or five seats for $400/month. Unlimited minds and businesses. 30 days free, no card to start. You use it inside Claude, which has its own plan. | Priced per workspace in credits, “No per-seat licenses”. Free is $0 with “up to $100 credits for free”.[3] “Paid workspace plans start at $50 per month for 20,000 credits, with no per-seat charge.”[4] The Team plan shown on the pricing page is $100 a month with “40,000 credits monthly”. Enterprise is custom. “A quick Slack question might cost 50-100 credits.”[3] |
What you set up and keep up yourself with Viktor
Viktor is a capable worker. It connects to your tools and runs the jobs you give it. Keeping six clients apart, and deciding what runs for each one, is still yours. From Viktor's own pages:
| The job | With Viktor | With Armbrain |
|---|---|---|
| Keeping clients apart | Each client getting an automatically isolated context: “Not today.” You label connections and set access per connection.[4] | Each client gets its own mind. Email is routed to the right client. Notion pages go to the client you pick once. Unsure items wait for your review. |
| Setting up recurring work | Each new scheduled job “leaves it paused” until someone approves it[2], and “Scheduled automations run on credits too.”[3] | Briefings and overdue flags run on their own. |
| Keeping memory current between jobs | Not a stated feature on the pages we checked. | Re-checked on a schedule, Gmail about every 7 minutes. |
| Tracking promises | Not a stated feature on the pages we checked. | Pulled from meetings and email, kept on a list until done. |
| Spotting quiet clients | Not a stated feature on the pages we checked. | A weekly client health read flags them. |
| EOS rocks, sprints, scorecards, L10 | Not a stated feature on the pages we checked. | Built in. |
Which one fits
- Choose Viktor alone ifyou mostly need tasks done in Slack or Teams, like reports, audits and decks, you work with one company or a few clients you are happy to label and keep apart yourself, and you are glad to set up and approve each scheduled job.
- Add Armbrain ifyou run several clients and want each one kept in its own mind, collected and kept current for you. It has your briefing ready each weekday morning, tracks promises, flags clients who have gone quiet, and brings EOS tools into Claude. Its briefings can land in the same Slack your team already uses.
Common questions
Does Viktor collect my client data automatically?
Yes, from the tools you connect and the chat channels it is invited to, and it pulls fresh numbers when a job runs. Its agencies page says it does not automatically keep each client in a separate context today. Armbrain collects meetings, email, calendar, files and CRM records after a one-time connection and sorts them into each client's own mind.
Can Viktor keep my clients separate?
Not automatically, by Viktor's own agencies page. You can label connections and limit access per connection. Armbrain gives each client its own mind and holds anything it is unsure about for your review.
Can Viktor work while I sleep?
Yes. Viktor runs scheduled jobs that someone on your team approves, and they use credits. Armbrain does its overnight work without you setting up jobs: it flags overdue commitments and has your morning briefing ready when you start.
Is Armbrain a replacement for Viktor?
No. They do different jobs. Viktor does tasks in Slack and Teams, like reports and decks. Armbrain keeps a self-updating memory for each client inside Claude, and can send your briefing to Slack.
How is the pricing different?
Viktor is priced per workspace in credits, with paid plans from $50 a month after free starter credits. Armbrain: Personal mind free. $90 per person/month, or five seats for $400/month. Unlimited minds and businesses. 30 days free, no card to start.
How long does Armbrain take to set up?
About 30 minutes to connect your tools. After that, Armbrain does the collecting.
They do different jobs, so some teams use both: Viktor for tasks in Slack, Armbrain for each client's memory inside Claude. Armbrain setup takes about 30 minutes.
