What Viktor does well
Credit where it's due. Viktor is a strong product, and for some teams it's the right pick:
If your priority is the widest possible integration list or native Teams support, Viktor deserves a look. Yasmine is Slack-first and runs on the Claude model family — deliberately.
Where Yasmine is different
Yasmine makes a different set of bets — ones that matter most to teams handling real data and real systems.
| Yasmine | Viktor | |
|---|---|---|
| Runs on your own Claude subscription | Yes — no token resale | Bundled credits / its own billing |
| Per-workspace hard isolation | Dedicated environment per customer | Managed, multi-tenant |
| Approval gates on every write | Yes, in-channel | Varies |
| Per-channel coworker with own memory | Yes | Org-wide employee |
| Open source / self-hostable | Yes | No |
| Data used to train models | Never | Per their terms |
| Integrations | 500+ | 3,200+ |
| Platforms | Slack | Slack + Teams |
Your own Claude subscription vs. bundled credits
This is the biggest practical difference. Yasmine runs on the Claude subscription you already pay for. Your conversations go to your own Anthropic account — not pooled through a vendor, not marked up as resold tokens. If your team already pays for Claude, there's nothing extra to buy on the AI side, and your costs stay predictable instead of scaling with opaque per-task credits.
Isolation and data
Every Yasmine workspace gets its own dedicated, isolated environment — separate compute, storage, and memory. Nothing is shared between customers. That's what makes it safe to give a coworker access to your inbox, your CRM, or your codebase — and it's why Yasmine can run code on the Dev plan without putting anyone else's data nearby.
Your data goes to your account. Never pooled. Never used to train a model. And because Yasmine is open source, you can read exactly how it works — or self-host it entirely.
A coworker per channel, not one org-wide employee
Viktor positions itself as a single AI employee for the whole organization. Yasmine takes the opposite shape: every channel becomes its own coworker, with separate memory and context. A #finance Yasmine and a #marketing Yasmine never mix things up. For teams that want focused, accountable helpers rather than one all-seeing agent, that separation is a feature, not a limitation.
When to pick which
Try Yasmine as your Viktor alternative
The best way to compare is to give both a real task. Yasmine installs in about two minutes: add her to Slack, connect your Claude subscription, and hand her the first thing on your list.
