In their own words
Datify
Datify is a web-based AI execution platform for planning and carrying out business work across connected tools. Users describe an objective in plain English, review a proposed plan, and approve it; Datify then reports which actions succeeded, were skipped, or failed. Listed work includes follow-up, scheduling, customer communications, campaigns, and administration. The service is aimed at small and mid-sized businesses seeking AI operations capability without hiring an operations team. Self-serve execution uses credits: one per action, with charges for successful actions only. The Free plan is £0 and includes unlimited manual use with no contact caps; Starter is £49/mo for one operative and one job. Growth costs £197/mo, Scale £497/mo, and Managed starts at £5k/mo. New workspaces begin in Prepare mode, actions are bounded by caps, and high-impact actions need confirmation. Datify records actions in an append-only audit log and says reversible actions can be rolled back. Users can export or delete a workspace, and export customers, jobs, quotes, invoices, and message history in a standard format on any plan.
Vellum
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.
