How it works

One assistant. Many models. You still know where your data went.

Most AI tools tie you to a single model. Friday doesn't. He reads what you asked for and sends it to whichever model suits it — then tells you which one answered. This page explains how that choice is made, and exactly which companies are involved.

How a message gets answered

1. 1
   Friday reads the request. A quick question and a long piece of reasoning need different models. He decides which this is before spending anything.
2. 2
   He checks what the request touches. If it involves your email, calendar, notes or saved memories, that changes which providers are allowed to see it — see below.
3. 3
   He picks a model and answers. Simple work goes to a fast, inexpensive model. Hard work goes to a frontier one. The point is to stop spending frontier prices on questions that don't need them.
4. 4
   If a provider is down, he keeps working. Rather than failing, Friday falls through to another model that is approved for whatever the request contains.

What happens to private things

Some of what you give Friday is more sensitive than the rest — your inbox, your calendar, your notes, the documents you upload. When a request involves those, Friday restricts it to providers we've approved for it. Providers we haven't approved are not sent the request, and are not offered the tools that could reach it.

When you give a team of agents a job to work through, that path is stricter still: it only uses approved providers, whether or not the content looks sensitive, and if none are available the job fails and tells you rather than quietly using someone else. We are still extending that same restriction to the remaining background jobs, so we will not yet claim it holds everywhere — our Privacy Policy says the same, and we would rather the two pages agree than sound impressive.

Who sees your data

Every company below receives something when you use Friday — a message, a file, a search term, or just the fact that you loaded a page. They are all here, including the ones whose terms we don't like.

The model rows are generated from the same configuration the router enforces, so who is allowed to receive a prompt cannot drift from what the software actually does. The supporting-service rows are maintained by hand: nothing in the code checks them, so treat them as our written statement rather than something the software proves. Tell us if you find one out of date.

Accounts you connect

The table above is companies we chose. Connecting your own accounts adds more, and you should know what that does before you do it.

If you connect Gmail, Google Calendar or Notion, Friday reads from them on your behalf. That doesn't hand your mail to a company that didn't already have it — Google already holds your Gmail. What it does mean is that anything Friday reads from those accounts can become part of a message to a model, and is then subject to everything above: it is treated as private, so only approved providers can see it.

Friday can also connect to other tools through a standard called MCP. Those appear in a directory in the app, and none of them receive anything until you connect one yourself. When you do, you are choosing to add that company to this list. Disconnecting stops it.

What we don't claim

Vendor terms last read 22 August 2026. The rows above are checked by hand against each provider’s published terms.

Questions

If you want to know which provider handled a particular request, or you'd rather we switched a provider off for your account entirely, email youssef@broomit.net and we'll do it.
