Personal AI assistant with persistent memory that acts across email, calendar, files and chat apps
Vellum now sells a personal assistant that keeps long-term memory, runs tasks in the background and takes actions - web browsing, file work, code execution, calendar and messaging - from the web, a Mac app, iOS, CLI, Slack and Telegram. The runtime is MIT-licensed for self-hosting, or you rent a hosted machine with bundled usage credits from $30/month after a free start. Note the identity shift: this domain previously marketed an enterprise LLM development platform, and docs.vellum.ai still documents that product, so verify which Vellum you are evaluating.
Free tier covers initial tasks; Mighty $30/month (1 vCPU / 2 GiB machine, 10 GB storage, $25 usage credits), Super $100/month, Ultra $200/month, plus custom plans. Credits are pay-as-you-go beyond the bundles; self-hosting the open-source runtime avoids platform fees.
Use tool ↗An ambitious personal agent that pairs deep memory with real tool access, and the MIT-licensed runtime is a rare escape hatch in this category. The company is visibly mid-pivot - its docs subdomain still describes the earlier enterprise LLM platform - so expect product churn and check that plan credits cover your actual usage.
Watch out: Older Vellum URLs circulating in directories (including /sp/showcase) now return 404; the domain's flagship is the personal assistant while docs.vellum.ai still documents the legacy LLM development platform.
