Ask for a plan. Get the real one.

Describe a dive and the assistant builds it in the planner, checks the gases, works out a blend or debriefs a dive, with the same checks as every other screen. It drafts; you check.

A conversation that ends in a plan.

Every number in a reply comes from the planner, not from the language model. Every plan it makes is an ordinary plan you can open, edit and check.

In the handbook The planning assistant
Plan
Describe the dive in words; the assistant builds it in the planner and opens it.
Check
Ask about a mix, a switch or a limit; answers come from the planner’s checks.
Blend
Ask for a fill and get the steps, from what is already in the tank.
Debrief
After the dive, ask what changed against the plan and why it matters.

Plan created. Runtime 67 min, TTS 39 min, first stop at 24 m. EAN50 comes in at 21 m and EAN80 at 9 m, both at or under 1.6 bar. The planner raised no warnings on this one.

Could I take the same mix to 50 m?

Getting dense at this depth, past the 5.2 g/L advisory

Oxygen is fine at 50 m (ppO₂ 1.27 bar, MOD 56 m), but the gas is 5.5 g/L, past the 5.2 g/L density advisory. More helium would bring it back under. Want me to compare 18/45?
