A little flask app to write and validate haikus. It's definitely not perfect and makes some mistakes. It uses the syllables python library to estimate how many syllables are in each word.

You can check the override list at https://haikuvalidator.com/overrides and if you have any suggestions feel free to let me know any words that are broken.

This is my first time making a web app. Hoping that someone finds it fun / useful.

close comes up as 2 syllables in the app, should be 1.

Nice and simple, very nice app.

"Sometimes" and "sense" are both wrong. I don't think this library is very good
"wrote" came up as 2 syllables :(
"space" is counted as 2 syllables, should be 1

Seems like a general problem with words ending in 'e'

This is a haiku

I need one to test this app

Love the internet!

A little pedantic, but: this will tell you if a poem is shaped like the common English conception of a haiku, but it won't tell you if this is a haiku, because a haiku is more than just counting syllables.

Aside from the fact that "syllables" is not exactly the unit being counted in haiku, there are also considerations of theme, tone, and a sort of "open-ended-ness" – among other considerations.

This article served as my introduction to the actual complexities of haiku: https://forgottenpoets.substack.com/p/haiku-thursdays-one-pl...

Super fun idea! That syllables package might not be robust enough for this purpose. Even in its documentation's super simple code samples, it estimates the word estimate wrong haha. I think that's somewhat meant to be an admission by the author that it is an estimate.

>>> import syllables

>>> syllables.estimate('estimate')

Doesn't matter in the context of making a fun web app though, cool idea!

Authentic haiku

need a season word (kigo).

It's true; look it up.

It does not matter

As long as you have some fun

“Trace” is overestimated and “noel” is underestimated.

Very cool! I like the interface. For anyone interested in this and similar ideas, haiku/senryū detection is a feature of this old project of mine: https://versepad.com
I don't know what a

haiku is. can anyone

please explain it?

Cool idea. Note that sometimes syllables depend on context. So syllable count I think needs to be a range.

Blessed vs “bless-ed” for example

Camera can be said cam-ra or cam-er-a for example.

Type your haiku.

Hope that it validates

and smile when it does.

Edit: Little tools like this are nice. It's simple, it works, and it's just one of those little toys that people can use to have simple fun.

Completely fails on famous haiku:

柿くへば

鐘が鳴るなり

法隆寺

It thinks the word "service" is three syllables and "chocolate" is four.
Potato chip bag

Crunchy, like its fried contents

I ate the chip bag

It doesn’t work for actual Japanese haiku.
I truly do not understand how Ænglish poetry works, do you appreciate written form or vocalizations?

But Validator works on sane languages too:
