Brief
Turn vague instructions into instructions anyone can act on
Brief diagnoses vague instructions with a 5W2H check, flags what's missing (what / by when / done criteria), and rewrites them into instructions anyone would execute the same way. No signup — try instantly at app.briefos.jp/try.
Hey Product Hunt! 👋
I built Brief because I kept sending things like "just handle it nicely" to my team and getting back work that missed what I actually meant — then having to redo the whole exchange.
The problem wasn't laziness on either side. Vague instructions look complete in the moment, but leave out just enough (what counts as done, by when, how much) that two people fill the gaps differently.
Brief runs your instruction through a 5W2H diagnosis, points out exactly what's missing, and rewrites it into something anyone would read the same way — then you copy it straight into whatever chat/email you already use.
Early versions tried to be a full task-management app, but that added friction nobody wanted for a "before you hit send" moment — so I stripped it down to: paste, diagnose, copy. No signup needed, try it here: app.briefos.jp/try
Would love feedback, especially on the tone-conversion feature that softens urgent/blunt phrasing without losing the original intent.
