Sintra vs Viktor

Sintra

• Solo founders and small businesses covering many roles
• Routine marketing work such as social posts, emails and SEO copy
• Owners who want ready-made helpers rather than building agents

Viktor

• Teams that already work in Slack or Microsoft Teams
• Recurring reports pulled from ads, billing and CRM tools
• Small companies that want internal tools built without engineers

Sintra

• The website advertises no free plan or free trial; all paid plans carry a 14-day money-back guarantee.
• Prices here are the crossed-out list prices. When checked, the site sold the plans at 50% to 70% less and its FAQ gave $48.50 a month as the starting price.
• Each plan includes 250 credits a month for advanced AI actions; more must be bought as top-ups.
• The lower monthly rates on the 3-month and 12-month plans are charged as one payment for the whole term.

Viktor

• Viktor is used through Slack or Microsoft Teams; its site lists no standalone desktop or mobile app.
• The free allowance is a one-time $100 in credits rather than a recurring free plan.
• Everything runs on workspace credits, including scheduled automations, so frequent jobs raise the monthly cost.
• Per-user spend caps, invoicing and custom billing terms are reserved for Enterprise.

Sintra

Twelve role-based helpers

Every plan includes all 12 helpers, each with a set role, among them Soshie for social media, Cassie for customer support, Seomi for SEO, Milli for sales and Vizzy as a virtual assistant.

Brain AI

A shared knowledge base of brand details, files and website content that every helper draws on, so output stays consistent with the business.

Integrations that take action

One-click connections let helpers send and reply to Gmail or Outlook mail, create Google Calendar events, publish to Facebook, Instagram and LinkedIn, and update Notion pages.

One-click use cases

Preset tasks run with a few clicks, such as competitor research, finding SEO keywords, generating email campaigns and removing image backgrounds.

Profiles and shared workspaces

Unlimited business profiles can be created, each with its own context, and a workspace can be shared with teammates.

Work in 100+ languages

Helpers work in more than 100 languages, for example writing social posts in Italian or answering emails in German.

Viktor

Lives in Slack and Microsoft Teams

Installed from the Slack App Directory or Microsoft Teams and addressed in threads and mentions like a colleague, so everyone on the team can work with it.

Connections to 3,200+ tools

27 native integrations with full read and write access, including Stripe, GitHub, Linear and Notion, plus more than 3,200 tools through managed connectors.

Finished deliverables

Queries connected tools, analyzes the data and hands back outputs such as PDFs, spreadsheets, reports and dashboards rather than instructions.

Scheduled tasks

Recurring work, such as a weekly revenue dashboard or a morning metrics summary, runs on a schedule. Scheduled automations use credits each time they run.

Web apps and code

Builds and deploys internal tools as web apps with a database, auth and hosting, and can clone a repository, write a fix on a branch and open a pull request.

Approvals and activity log

Sensitive actions wait for a person's approval before they run, and Viktor posts back what changed, with its activity logged.
