Channels
iOS app with Home Screen widgets, native Mac app, web app, voice, email, Slack, Telegram, Microsoft Teams, and Discord, now an official channel with a setup wizard. Sent messages can be edited in place in Slack and Telegram. Every surface shares the same memory and identity.
Direct messages in Slack, dedicated gumball@gumloop.ai email address, and web dashboard.
Execution
Build me a habit tracker gets you a working, interactive app in the conversation. Read this page uses the browser extension to read your open tabs and act on the page you are looking at. Call the dentist and reschedule places an actual phone call with its own voice.
Executes API calls, web scraping, and Python scripts across distributed cloud workers.
Hosting
Run on-device as a native Mac app, on Vellum's managed cloud, or self-host on your own VPS.
Runs on Gumloop cloud workers with scheduled background triggers; no local hosting.
Integrations
Native agent skills plus 1-click integrations with 50+ services through managed OAuth, including native Calendly and Eventbrite. Your assistant acts in real services without you touching tokens or API keys.
Extensive pre-built connectors for Gmail, Outlook, Slack, Salesforce, HubSpot, Linear, and MCP servers.
Memory
Vellum builds a structured memory of your projects, people, and preferences automatically, across every surface. It sharpens with every conversation and correction, and there is nothing to configure: no files to curate, no engine to pick, no embedding provider to wire up.
Tracks personalized tone and design rules, situational highlights, and past run feedback in cloud storage.
Modularity
Builds its own skills, learns your tone, and adapts based on what you reward and correct. Install new skills from a growing library, or just ask and it figures out a way.
Extensible visual node canvas, reusable SKILL.md imports, and multi-agent delegation.
Open Source
Open source under MIT license. Full codebase available on GitHub.
Proprietary cloud platform with closed-source engine, web builder, and orchestration harness.
Pricing
Free Base plan with free credits to start. Paid plans from $30/mo (Mighty), $100 (Super), and $200 (Ultra) with pay-as-you-go credits, configurable compute and storage, and your assistant's own email and subdomain on higher tiers.
14-day free trial, Pro plan from $37 per month on a credit slider, and custom Enterprise contracts.
Privacy
Run locally on Mac, in Vellum Cloud, or self-host. Vellum never has access to your data on any deployment path.
Processes data across Gumloop cloud infrastructure, with dedicated VPC options on Enterprise contracts.
Schedules
Built-in scheduling for daily briefings, weekly reports, and hourly checks that just run on a cadence.
Automated morning briefings, pre-meeting triggers, and custom interval schedules.
Security
Credentials live in an isolated vault and never enter the model layer, so prompt injection can't exfiltrate your keys. Every sensitive action asks permission with a risk badge before it runs, and guardian approvals land in one inbox.
Admin-governed connector controls, role-based skill permissions, and credit rate limits.
Setup
No terminal, no API keys, no daemon. Voice-first onboarding is the default: your first experience is speaking, not configuring. Free, no credit card, up in minutes.
Auto-created on account signup; connects to workplace apps via standard browser OAuth.
Storage
Vellum Cloud: 3 GB RAM and 4 GB storage by default. Mac app runs on standard Mac hardware.
Stores generated artifacts, interactive apps, and company brain documents in Gumloop cloud.
Trust
Every sensitive action asks first with a risk badge, guardian approvals land in one inbox, and you can export or delete your data at any time. The trust model is written down in the docs.
Interactive Needs Work feedback in Slack and step-by-step plan reviews before agent execution.
