Three Lines: How to Write a Precise Prompt for a Haiku Generator
The Three Lines generator creates three original three-line haiku based on your description. To get a meaningful result, it is important to fill in the input fields correctly. In this article, we will look at how to compose a precise prompt: what to write in the "Your text or idea" field, how to set the tone and style, how to specify length or duration, and how to check the finished text and understand the tool's limitations.
Open tool: Haiku generator ↗What exactly the tool does
Three Lines is a web form with text fields. You enter an idea or ready text, choose the output language, optionally refine the style, and press the generate button. The tool returns one result in a separate panel: three haiku, each consisting of three lines. The result can be copied or downloaded as a plain text TXT file.
It is important to understand: the tool does not automatically check strict syllable count. If you write in a language where syllable counting is ambiguous (for example, in Russian or English), the model can only approximately follow the 5-7-5 pattern. In Japanese, the syllable structure is more predictable, but variations are still possible. Therefore, in your prompt you should separately indicate how strictly you want the syllables to be observed.
The tool works only with text. It does not generate images, audio, or video. Only text fields are available, and the result is plain text. There are no sliders, style presets, or levels of changes in the interface.
Bad prompt: "Write a haiku." Good prompt: "Write three haiku in Russian about rain on an empty railway platform. Tone — calm, contemplative. Strictly follow the 5-7-5 pattern if possible; if not, explain why. Length of each line — no more than 12 words."
The "Your text or idea" field: context and purpose
This is the main field. Here you set the topic, context, and purpose. The more specific the description, the more accurate the result. Instead of an abstract "about nature," it is better to write "about the first snow in a city park where children are building a snowman." Indicate what exactly should be the focus: an object, an action, a feeling.
If you already have a draft or a set of words, insert them into this field. The tool can use your text as a basis. For example, you can enter "rain, platform, empty, train whistle" and ask to turn this into three haiku. This way you retain control over the imagery.
Do not forget about the limit: the first field accepts up to 8000 characters, the details field — up to 1000 characters. This is enough for a detailed description. If the text is longer, shorten it or break it into parts.
Example input: "Topic: autumn evening in a village. Purpose: to convey a feeling of light sadness and calm. Required images: fog, haystack, distant dog barking. Language — Russian. Style — classical, without rhyme."
The "Tone, style or format" field: how to set the character of the text
In this field, you can refine the emotional coloring, literary movement, or special requirements for form. For example: "ironic," "melancholic," "solemn," "in the spirit of Zen," "without pronouns," "only nouns and verbs." This helps the model choose appropriate vocabulary.
If you want a strict syllable count, write about it directly: "Follow 5-7-5 syllables in each line. If in Russian this is impossible due to different syllabification, indicate this in a note." The model will try to comply, but does not guarantee a perfect result. In Japanese, syllables are counted by morae, and the tool may not distinguish long sounds, so check manually.
The format can also be limited: "each haiku must end with a punctuation mark," "no capital letters," "lowercase letters." But remember: the tool does not support complex formatting, only plain text.
Example: "Tone — calm, contemplative. Style — minimalist. Format: three haiku, each on a separate line, with an empty line between haiku. No rhyme. Syllables: try to follow 5-7-5, but if not possible, write about it after the text."
The "Length or duration" field: what it means
The name of the field can be confusing because haiku is a short poem. In fact, this field sets the volume or quantity. You can specify how many haiku to generate (by default three), or limit the length of each line. For example: "Three haiku, each no more than 10 words."
If you leave the field empty, the tool will generate three haiku as stated in the description. But it is better to explicitly write "three haiku" or "exactly three" to avoid misunderstanding. You can also specify "each line — no more than 7 syllables" if you do not require a strict pattern.
Do not write "make it longer" or "make it shorter" without specifics. The model may interpret this as a request to change the number of lines, which would violate the haiku format. It is better to use measurable instructions: number of haiku, maximum number of words or syllables.
Example: "Generate exactly three haiku. Each haiku has three lines. Maximum line length — 12 words. If possible, follow 5-7-5 syllables."
Bad and good prompts: comparison
A bad prompt is often too general: "Write a haiku about nature." The model may produce banal lines unrelated to your purpose. Moreover, without specifying language and style, the result may be in another language or in an inappropriate tone.
A good prompt contains context, purpose, format, and constraints. For example: "Write three haiku in Russian about rain on an empty railway platform. Purpose — to convey loneliness and waiting. Tone — melancholic, without pathos. Format: three haiku, each of three lines. Constraints: no rhyme, no pronouns "I," "you." Syllables: try to follow 5-7-5 if possible; if not — explain why."
The difference is obvious: in the second case, the model receives clear instructions and can better complete the task. However, even a good prompt does not guarantee a perfect result — the model can make mistakes, and that is normal.
Bad: "Haiku about autumn." Good: "Three haiku in Russian about late autumn in the forest. Tone — quiet, slightly sad. Images: wet leaves, fog, empty path. Format: three haiku, each three lines. No rhyme. Syllables: 5-7-5 if possible, otherwise explain."
How to check the result
After generation, read the text carefully. Check whether it matches your prompt: topic, tone, number of haiku, number of lines. If you asked to follow syllables, count them manually. In Russian, syllable counting depends on pronunciation, so discrepancies are possible. In Japanese, keep in mind that the tool may not distinguish long vowels and the final "n" in a syllable.
Pay attention to originality. The tool creates new texts, but may accidentally repeat known lines. If uniqueness is important to you, check the text in a search engine. Also make sure there is no nonsense or grammar violations in the text.
If the result does not satisfy you, change the prompt: add more details, refine the style, limit the vocabulary. You can generate several variants and choose the best one. Remember that the model may contain errors, and the queue and availability may vary.
Check: "In the first haiku, three lines. Syllables: 5-7-5? First line: "Rain knocks on the roof" — 6 syllables, not 5. So the strict pattern is not followed. In the note, the model wrote that in Russian variations are possible. This is acceptable if you did not require absolute strictness."
Tool limitations
Three Lines is a text generator. It does not create images, audio, or video. Vectors are available only in SVG and PNG formats, speech — via eSpeak in WAV, subtitles — SRT. But these functions belong to other tools, not to the haiku generator. Do not expect it to export to DOCX or PDF, batch processing, automatic saving, or integrations.
The tool has no settings for comparing versions, highlighting changes, or special modes. There is no registration, premium plan, email delivery, or document upload. All you can do with the result is copy it or download it as TXT.
The model can make mistakes, and the queue and availability vary. Do not use the tool to create legal, financial, or medical documents. If you write on health, finance, or law topics, remember that this is educational content, not personal advice.
Example limitation: "The tool will not check syllables automatically. If you need a strict pattern, check manually. Also, it will not save generation history — copy the result immediately."
The Three Lines generator is a simple tool for creating haiku based on your description. To get a useful result, fill in the fields specifically: indicate the topic, purpose, tone, format, and constraints. Remember that strict syllable counting may be uncertain, especially in Russian. Check the text manually and do not expect features that do not exist. Use the tool as an assistant for creativity, not as a source of guaranteed masterpieces.
