Tunang is DiveLogic’s diving assistant: a model built for this subject rather than a general one asked about it, wired into the calculations the planner runs. Ask in ordinary language; when the answer needs a number, Tunang works it out rather than recalling it, so the figure you get is the figure the app would give you.

What a reply carries
A line appears in the thread while a calculation runs (Analysing gas mix, Planning the dive), and becomes a card when the answer comes back.
Let me analyse that mix at depth.
At 45 m it runs 1.16 bar of oxygen, which is comfortably inside a 1.4 bar working limit, and its maximum operating depth is 56.7 m. Narcosis is equivalent to 20.2 m on air, and density is 4.1 g/L — under the 5.2 g/L figure where work of breathing starts to matter. It is a reasonable bottom mix for that depth.
Tunang restates the key numbers in words, so a follow-up has something to refer back to. Given a value it cannot use, the calculation refuses and names it: no card is drawn, and nothing is swapped for a default.
A request for a whole dive needs a name, a depth and bottom time, and one gas with its role. Its card carries an Open in Planner button, which loads the plan and saves it.
How it answers
- It prefers named sources: agency material, manufacturer manuals, DAN, NOAA, the US Navy Diving Manual, peer-reviewed diving-medicine literature. It never invents a source, a standard or a limit, and where the evidence is weak or conflicting it says so.
- It refuses the word “safe”. “You’ll be fine” and “people do it all the time” are forbidden. It says “lower risk” or “more conservative” instead.
- In a chat it sees the conversation, not your dive. An answer that sounds specific to your plan is a general answer using your numbers.
