Which one is for you
Pick Ask Sage if
- Fits if you buy for a government agency or defense contractor
- Works for teams that want to compare several models in one controlled workspace
Look elsewhere if
- Not for you if you want a price, as none is published and cost follows token volume
- Skip it if you are an individual, since it is aimed at defense, federal and commercial enterprise buyers
- Too light on detail: no integrations or free tier are listed on the pages read
Pick Vellum if
- Fits if you want one assistant that keeps your preferences across devices and chat apps
- Works for people who want to read the code or host the open-source runtime themselves
Look elsewhere if
- Skip it if you want free to mean free, as every reply, search and image draws on credits at $1 each
- Not for you if you bank what you don't use: included usage doesn't roll over and bought credits expire after 12 months
- Tight if you're on Windows or Linux, since the Windows app is a dev build and there's no Linux desktop client
- Watch out: the iPhone and Android apps are clients for the cloud assistant and can't run it on the phone
- Pricey if you want a custom subdomain, static IP or priority support, which start at Super for $100 a month
How we grade them
| 1.6GPAAsk SageWeak | 2.6GPAVellumGood | |
|---|---|---|
| Value for money | CNo price is published. The How to Buy page lists card payment, cloud marketplaces and government contract vehicles, and usage is sold as tokens. | CMighty is $30 a month, right on the line where the dearest quarter of agent tools here begins, for a Small machine, 10 GiB of storage and a monthly usage allowance whose size the listing never states. Model usage is extra at $1 a credit. Super is $100 and Ultra $200. |
| Free plan and trial | FNo free plan or trial is listed, so the way in is a sales conversation. | BBase is free forever with no card, and the MIT runtime runs on your own Mac or Linux box for nothing. But free covers the hosting, not the thinking: every reply, search and image draws on credits at $1 each. Self-host with your own model key and one person could live on it. |
| Features | CMany models in one workspace, an agent builder, a workbook, code canvas, model compare and hosting options. The pages read give few limits. | CA knowledge base of facts and preferences it recalls later, skills across Google Workspace, Slack, Notion and GitHub, Allow or Deny prompts on risky actions, computer control and a form-filling Chrome extension. But the docs name two gaps: the Windows app is a dev build, and the phone apps can't run it locally. |
| Ease of use | CNo store rating on record. Accounts, tokens and team distribution have to be set up. | CNo rating on record. The cloud default means nothing to host, but you still connect OAuth integrations, prepay credits and build trust rules before the permission prompts stop interrupting. The docs also call the Windows app a dev build. |
| Platforms and integrations | CWeb platform only on the pages read. No integrations list in the listing, and no apps. | AWeb, Mac, Windows, iPhone, Android, a Chrome extension and a command line, plus Telegram, Slack, email, voice and phone calls, with integrations for Gmail, Calendar, Slack, Notion, Linear and GitHub. No Linux desktop client, and the phone apps are cloud clients. |
| Best for | multi-model AI workspace for government and enterprise | one assistant with memory on every device |

Worth knowing
Ask Sage

- Usage is sold as tokens that teams can distribute among members, so cost depends on volume.

Vellum
- The Base plan is free to host, but model usage, web search and image generation are paid for in prepaid credits at $1 per credit.
- Included monthly usage does not roll over, and pay-as-you-go credits expire twelve months after purchase.
- The docs describe the Windows app as a dev build tied to Vellum's development environment, and no Linux desktop client is shipped.

- Computer and browser control
- The desktop app adds voice input and computer control, and a Chrome extension lets the assistant read open tabs, fill in forms and act on the page in front of you.

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
