Your assistant just produced the thing you needed — a pricing breakdown, a bug reproduction, a plan with the tradeoffs laid out. Now someone else needs to see it. The fastest path is sitting right there: hit share, copy the link, paste it into a message. Sometimes that's exactly the right call. Whether it is this time depends on what you actually want back from the person reading it.
What a share link gets right
Give it its due, because it earns its use often. It's one click on your side, nothing to configure, and no new account for you to manage. The recipient opens a URL and sees the conversation exactly as it happened — no summarizing in between, no risk that a retelling drops the detail that mattered. That makes it the right tool whenever the point is the artifact itself: a striking output worth showing off, a bug reproduction where the exact steps are the message, a record of what a model actually said and in what order. If someone just needs to see it, a link is less work than anything else in this comparison, RelayLink included.
What the link doesn't do
What a share link doesn't do is ask for anything. It arrives with no explicit question attached, so the recipient has to infer from context why you sent it and what, if anything, you want from them. There's no context brief either — the conversation was shaped by everything you already knew going in, and none of that gets reconstructed for someone arriving cold. They either already have the background or they're stuck reconstructing it from your side of a back-and-forth with a model.
The bigger cost is that a link is all-or-nothing. You can't send the conclusion without the four drafts that led to it — every wrong turn and half-formed idea you talked through out loud goes along for the ride, because a share link isn't a place you get to redact. And if the recipient's instinct is to paste that link's content into their own AI to help them respond, that AI inherits your framing along with it — your conclusions, your phrasing, your blind spots — instead of reasoning toward its own view. What was supposed to get you a second opinion quietly hands back your first one instead.
What a briefing sends instead
A RelayLink briefing costs more to produce, honestly — your assistant has to compose it, not just export a link — and that extra effort is the whole difference it buys. Instead of the session, it sends the parts of the session written for a stranger to read: an explicit ask with a response shape and an honest urgency, a context brief written for someone with zero background, assumptions labeled as either stated by you or inferred by your assistant, and a note in your own words carrying a provenance label that says exactly whose it is. The full shape of a briefing is worth reading on its own.
Nothing upstream of what you reviewed goes with it. The recipient's assistant, if they connect one, can read the same briefing through MCP and help them think through a reply privately — a symmetry that doesn't exist with a share link, which only ever has one side's model looking at it.
Same conversation, two different sends
Say the question was whether to renew a vendor contract, and your assistant spent twenty minutes comparing three options before you landed on one. Share the link, and your colleague gets the whole twenty minutes: the two options you talked yourself out of, a tangent about a competitor, and, somewhere inside all of it, your actual position, which they now have to go find. Send a briefing, and they get the ask — sign off by Friday — the three options and why two were dropped, and your note in your own words. One is a recording. The other is a question, addressed to them specifically, that they can actually answer.
Both have a place. A share link is exactly right when the point is proof — nobody needs the twenty minutes replayed if all they're doing is confirming what the model said. But the moment you need something back, the rule holds: share a link to show what happened; send a briefing to get an answer.
If there's a decision riding on someone else's answer right now, connect your assistant and have it draft the briefing instead of copying the link.
