VERDICT

Should I use Vellum (Personal AI Assistant)?

An assistant that knows you deeply, evolves alongside you, and belongs to no one else. Powered by memory that remembers the way you do. - vellum.ai

Depends. Worth trying if you're a Mac user who wants an open-source, memory-first personal AI and tolerates early-stage risk. Skip it if you need a proven product with clear pricing — evidence is muddied by several unrelated products also named Vellum.

Confidence

Medium. Based on 14 public sources. Heavy name collision: vellum.pub (book formatter), Ashlar-Vellum CAD (source of all CVEs found), vellum.ie (payments) and Vellum Insurance are unrelated products. Only vellum.ai-family sources were treated as evidence for this product; the personal assistant itself has thin independent review coverage.

Gotchas - check before you buy

high

Most 'Vellum' reviews online are for the unrelated $249 book-formatting app — do not trust them here

medium

Pricing ambiguity: 'open source' marketing versus paid tiers referenced in docs; confirm costs before committing data

medium

Strategy shifted twice in 2025 — enterprise platform, then personal assistant. Roadmap risk

medium

Memory features ingest personal context; read the data-privacy docs before syncing your life

  • Handles deeply personal memory data; retention practices need scrutiny

Open-source, memory-first personal AI from a funded but pivoting startup. Worth a test; ignore the book-formatter Vellum reviews.
