Broad platform access and persistent automation, with a relatively high paid entry tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Vellum is a personal AI assistant for automating tasks across files, web services, communication tools, calendars, and other connected systems. It suits individuals who want one assistant across web, Windows, macOS, iOS, Android, a Chrome extension, API access, and self-hosted deployment. Its feature set includes persistent memory, browser automation, scheduled and recurring background tasks, custom skill creation, OAuth-based integrations, and approval prompts for sensitive actions.
Pricing spans four plans. Base is free forever and includes a small machine with 1 vCPU and 2 GiB RAM, 6 GiB persistent storage, and pay-as-you-go credits. Mighty costs $30 per month and adds a small computer with 1 vCPU and 2 GiB RAM, 10 GB storage, and Mighty Usage. Super costs $100 per month with a medium computer, 2.5 vCPU, 5 GiB RAM, 30 GB storage, Super Usage, an assistant email, and a subdomain. Ultra costs $200 per month and provides a large computer with 4 vCPU, 8 GiB RAM, 60 GB storage, Ultra Usage, an assistant email, and a subdomain.
Vellum’s main strength is breadth across platforms and automation styles: users can connect services, interact with websites, schedule background work, author custom skills, and access the system through an HTTP REST API or CLI. Fine-grained permissions and explicit approval prompts provide control over sensitive actions. The integration set includes Google Workspace, GitHub, HubSpot, Linear, Twitter/X, Asana, Notion, Outlook/Microsoft 365, Todoist, Discord, Slack, and Telegram, with Slack and Telegram also documented as messaging adapters. Vellum is a strong fit for personal, cross-platform automation; teams seeking a conventional visual workflow builder or a lower-cost paid tier should consider alternatives.
