Viktor

Viktor is an AI coworker built by Zeta AI, Inc. that lives natively inside Slack, Microsoft Teams and Discord, with a browser app at viktor.com for people who want to work outside chat. Viktor has its own persistent cloud computer where it writes and executes code to complete tasks end to end. It delivers finished outputs such as PDFs, dashboards and web apps. You @mention Viktor like any colleague, describe what you need, and it queries your connected tools in a single autonomous run. Viktor also schedules recurring tasks and proactively proposes automations based on patterns it observes in how your team works. The vendor homepage states that Viktor is used by 68,000+ teams, and Zeta AI has raised a $75M Series A led by Accel. Viktor connects to 3,200+ tools with bidirectional read-write access, governed by an MCP-based tool permission architecture. Core confirmed integrations include Stripe, Meta Ads, Notion, GitHub, Salesforce, HubSpot, Google Ads, Linear, Jira, and Confluence. A read-only GitHub mode shipped on May 23, 2026, and a one-click Supabase integration covering database access, edge functions, and project management shipped on June 10, 2026. Viktor publishes its own MCP server, documented since July 31, 2026, which lets any MCP-compatible agent delegate work to Viktor over streamable HTTP using a scoped API key, with setup guides for Claude Code, Cursor and ChatGPT. Viktor also acts as an MCP client and connects out to external MCP servers, including Atlassian Rovo for Jira and Confluence. Viktor Skills packages expert-built toolkits, currently 55 skills across 2 toolkits. Viktor is listed in the official Slack App Directory, so its OAuth scopes, security posture, and store listing were reviewed and approved by Slack before release. Viktor fronts every new workspace $100 in credits with no credit card and no sales call, and those trial credits never expire. Paid usage begins once they are spent. Quick tasks cost 100 to 300 credits, complex multi-tool workflows cost 500 to 1,500, and the heaviest jobs cost 2,000 to 5,000. Billing is workspace-based rather than per seat. The Team plan starts at $50 per month for 20,000 credits and rises through $75 for 30,000, $100 for 40,000, $200 for 80,000, and $300 for 125,000, with the published ladder running to 20,000,000 credits for $50,000. Viktor states that 20,000 credits covers roughly 40 to 200 tasks depending on complexity. Unused plan credits roll over for one month, and exhausting the balance suspends credit-consuming functionality until credits are added, with an optional automatic top-up the customer configures and caps. Every plan includes every integration and capability, and only the credit allowance differs. Registered nonprofits receive 15% off every monthly plan. Enterprise is custom-priced and adds invoicing, a DPA, an SLA, and dedicated onboarding. All amounts are denominated and payable in US dollars. Viktor suits teams that work in Slack, Microsoft Teams or Discord and want an agent that carries tasks through to a finished output, with usage billed from shared workspace credits. Every self-serve plan is billed month to month, and invoicing and custom billing terms come with the custom-priced Enterprise tier. Teams that want to build their own trigger-based automations should look at Zapier (from $19.99/mo billed annually) or Make.com (from $9/mo billed annually). Teams that want a shared AI teammate in Slack with a private assistant for each person in iMessage and Gmail should look at Lindy (from $29.99/mo). Sensitive actions wait for approval by default. Current state Q4 2026: Viktor publishes both an MCP server and MCP client capability, and it is listed in the Slack App Directory. Microsoft Teams, Discord and a browser app are all live, with Discord added on August 1, 2026 and browser chat opened to all users on August 6, 2026. The model picker includes Claude Opus 5.5, Claude Sonnet 5.5, Claude Fable 5.1, Claude Opus 5, Claude Sonnet 5, Claude Fable 5, OpenAI GPT-6.1 Sol, OpenAI GPT-6 Sol and Luna, OpenAI GPT-5.6 Sol, Terra and Luna, Google Gemini, and Moonshot Kimi K3. Since September 23, 2026 the Smart preset runs on Claude Opus 5.5 and the Cheap preset on GPT-6 Luna, and since September 30, 2026 the Balanced and Ultra presets also run on Claude Opus 5.5. Since August 31, 2026, customers can also connect their own OpenRouter key to reach 300+ further models, billed to their own OpenRouter account. Security: SOC 2 Type 1 certified with Type II in progress and the report available under NDA, ISO 27001 in progress, GDPR aligned, and CCPA compliant. Enterprise buyers who require a completed SOC 2 Type II or ISO 27001 certificate should treat both as pending rather than held. Viktor does not train its own or third-party foundation models on customer data and does not permit its AI providers to do so, though it does build narrow internal quality models such as a model-selection router.
