How does it differ from a volitional form without っと?

My best guess is that it's a monologue marker, like な is.

question
verbs volitional-form
What does volitional form + っと mean?
I might be wrong, but it sounds to me like a shortened version of と思います,
something like "I think I will...".

Yes it's a sentence-ending particle which is usually used in monologues. [One
article](http://ci.nii.ac.jp/naid/110008799626) says the main function of this
っと is to casually convince/confirm something to the speaker themselves.
Perhaps it's like saying 'okay' to yourself.

>   * これで良しっと。
>   * 今日も1日お疲れさまでしたっと。 (before going to bed, to oneself)

Occasionally it's used when there's an actual listener. When that happens, it
expresses the speaker's sarcasm or indifference to the matter or the listener.

>   * 俺はもう知らないっと。 I don't care any more.
>   * 「彼女ができたんだ。」「そりゃよかったねっと。」 (indifferently)
