| Compare | Kilo | Vellum (Personal AI Assistant) |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Cost-conscious developers wanting BYOK | Mac users wanting a personal AI |
| Who it's not for | Non-developers . this is purely a coding agent | Enterprises needing a proven LLM platform . this team moved on |
| Privacy | Rough record: two 2026 CVEs, a 2025 supply-chain attack, and an August 2026 breach exposing user names and emails.10 | No known public vulnerabilities found in the sources reviewed. |
| Support quality | No support evidence in sources reviewed | Slack Connect plus in-app chat documented |
| Public sentiment | Reddit and review roundups praise its flexibility and price versus Cursor, but complain it's heavy, slow, and pricing is confusing. | Sentiment evidence mostly covers the company's earlier AI platform . 4.8/5 on Capterra (8 reviews) and positive G2 remarks . while the new personal assistant has few independent reviews yet. |
| Biggest gotcha | Starter Pass costs $19/mo for up to ~$26.60 usage credit; heavier use costs extra² | Most 'Vellum' reviews online are for the unrelated $249 book-formatting app . do not trust them here |
