🌸What is Haiku?

Haiku is a traditional form of Japanese poetry that captures a moment in time with just 17 syllables. It's like taking a photograph with wordsβ€”brief, beautiful, and meaningful.

5-7-5 Structure

Three lines with 5, 7, and 5 syllables. This rhythm creates natural flow.

Season Word (Kigo)

A word that references nature or time of year, grounding the poem.

Present Moment

Captures a single moment with vivid sensory details and imagery.

Classic Haiku Example:

Cherry blossoms fall

Soft petals dance in spring breeze

Fleeting beauty fades

This haiku follows 5-7-5 structure, uses "cherry blossoms" as a spring season word, and captures the ephemeral beauty of nature.

Tips for Writing Great Haikus

1. Show, Don't Tell

❌ Telling (Vague):

Love is so special
People care about each other
Feelings are important

βœ“ Showing (Vivid):

Two hands intertwined
Sunset paints the sky orange
Hearts beat as one now

2. Use Concrete Images

Replace abstract concepts with specific, sensory details that readers can see, hear, smell, taste, or touch.

  • β€’ Instead of "sad" β†’ "tears fall on autumn leaves"
  • β€’ Instead of "hot" β†’ "sweat drips down my face"
  • β€’ Instead of "beautiful" β†’ "moonlight on still water"

3. Adjust Syllable Count

If too short, add descriptive words:

"Sun shines" (2) β†’ "Bright sun shines today" (5)

If too long, simplify:

"Beautiful flowers blooming" (8) β†’ "Beautiful blooms sway" (5)

4. Capture a Single Moment

Haiku freezes time. Focus on one specific moment, not a story or sequence of events.

❌ Multiple moments:

I wake up early
Then I go outside to walk
Finally I sleep

βœ“ Single moment:

Dawn breaks silently
Mist rises from the cool lake
World still fast asleep

Frequently Asked Questions

Is the syllable counter accurate?

The syllable counter is approximately 80-90% accurate for English words. English syllable counting can be tricky due to pronunciation variations. If you notice an incorrect count, trust your own judgment and adjust accordingly.

Do I need to include a season word?

Traditional Japanese haiku always include a kigo (season word), but modern English haiku is more flexible. We recommend including one for authenticity and depth, but it's not strictly required. The tool encourages season words but doesn't enforce them.

Can I use this offline?

Yes! Quick Mode works completely offline since it uses local template generation. AI Mode and Coaching Mode require an internet connection to access Claude's AI capabilities.

Is this tool free to use?

100% free, forever. No hidden costs, no ads, no sign-up required. We believe poetry education should be accessible to everyone.

Can I save my haikus?

Currently, haikus are not saved automatically. Use the copy button to save your haiku to your clipboard, then paste it into a document, note app, or share it directly.

What's the difference between AI Mode and Quick Mode?

Quick Mode uses pre-written templates and generates instantly. It's great for learning structure but may feel formulaic. AI Mode uses Claude 3.5 Haiku to create unique, natural-sounding poetry tailored to your theme. It takes 2-5 seconds but produces much higher quality results.

Can I write haiku in other languages?

Currently, the tool is optimized for English haiku only. The syllable counter is specifically designed for English pronunciation patterns.
