LlamaIndex vs Vellum

LlamaIndex is a freemium platform for developers and enterprises automating document processing and AI workflows. LlamaParse handles more than 50 unstructured file types, including files with embedded images, complex layouts, multi-page tables and handwritten notes. Schema-based, language-model extraction agents convert unstructured content into structured insights without training. Workflows can divide documents into logical sections and classify them using natural-language descriptions and rules. Chunking and embedding pipelines support indexing and retrieval in RAG workflows. Community integrations cover data loaders, agent tools, language models, vector stores, observability and application frameworks. LlamaCloud connectors currently include Google Drive, SharePoint, S3 and Confluence. Free and Starter plans allow five concurrent parse, extract, classify and split jobs; Pro allows 20 and Enterprise 100. The Free plan has no listed price; Starter costs $50.00 per month. LlamaParse is commercial, while LlamaIndex and Workflows are open-source.

Vellum is a personal AI assistant that can read files, manage calendars, send email, run code, and control a computer. It saves preferences and context in its workspace for later conversations, and users can create, install, and manage skills. Listed OAuth services include Discord, GitHub, Google services, HubSpot, Linear, Twitter (X), Asana, Notion, Microsoft Outlook, and Todoist. Vellum says OAuth tokens stay in a credential vault rather than being exposed to the language model. Sensitive actions prompt for approval, and users can set trust rules for standing permissions. By default, conversation context is sent to Anthropic to generate responses; OpenAI, Google, OpenRouter, Fireworks, and local Ollama are listed alternatives. An internet connection is required. Vellum Cloud runs assistants in isolated environments with private storage and 24/7 availability. The Free plan includes first tasks and pay-as-you-go credits. Mighty costs $30 a month, Super $100 a month, and Ultra $200 a month. There is no shipped Linux desktop client, but Linux users can use the web app, Chrome extension, or self-host the runtime.
