Vellum

Vellum is a personal AI assistant built around persistent memory — it remembers how you work and your preferences across conversations, rather than starting fresh every session, and can take real actions on your behalf: browsing the web, managing files, running code, and handling calendar or app integrations. It maintains its own independent identity (its own email, GitHub account, and Slack presence) and is available on the web, macOS, iOS, command line, email, Telegram, and Slack. Who it's for: people who want an assistant that actually acts on tasks rather than just answering questions — drafting and sending things, managing files, or handling calendar logistics — and that improves over time by learning repeatable workflows. Strengths: the runtime is MIT-licensed and can run in Vellum's own encrypted cloud or on your own computer, giving real control over where data lives — a meaningful option for anyone wary of a fully cloud-only assistant with broad account access. Weaknesses and limitations: giving an AI assistant real accounts and the ability to take actions (send email, run code, manage files) is a materially bigger trust decision than a chat-only tool — worth understanding exactly what access you're granting before connecting real accounts. Specific pricing isn't shown on the main site; check Vellum's own pricing page for current rates. Real-world scenario: someone wants recurring tasks — triaging email, prepping a weekly summary, running a repeatable file-management routine — handled automatically instead of manually every time.
