Hashtag Generator

The generator segments the source with the browser’s locale-aware word tools where available. This matters for languages such as Chinese, Japanese and Thai, where spaces do not reliably mark every word boundary. It preserves Unicode letters instead of transliterating every result to ASCII.

Candidates come only from:

• topic words found in the source;
• adjacent topic-word pairs;
• repetition and original order within that source.

Common filler words for the active language and purely numeric tokens are skipped. When candidates have equal frequency, an adjacent pair is placed before a single term, then the original text order breaks the tie. The result is deterministic: the same text, language and limit produce the same draft.

No hidden trend database

This tool does not connect to a social network, advertising service or keyword database. It therefore cannot measure:

• current popularity or search volume;
• whether a tag is available, restricted or moderated;
• likely reach, engagement or ranking;
• whether a suggestion suits a particular audience or platform.

Those limitations are deliberate. A text-based candidate such as #CityWalk may describe a caption accurately, but only the publisher can decide whether it is useful and appropriate.

Check the destination before posting

Rules differ between services and can change. For example, YouTube’s current hashtag help says hashtags contain no spaces, warns against unrelated tags and ignores all hashtags on content that contains more than 60. That is YouTube guidance, not a universal rule for every network.

The word segmentation follows the same general problem described by Unicode Standard Annex #29: word boundaries vary by writing system and language, and dictionary-based tailoring can be needed. Browser results can therefore differ slightly across devices or browser versions. Always read the final tags before using them.

Private processing boundary

On the ordinary page, the source and output stay in browser memory. In the three-step funnel, the source and chosen limit are stored only in the current tab’s session storage for up to 30 minutes. At most three active drafts are retained. The URL contains an opaque random job identifier, never the caption or keywords, and nothing is sent through Livewire.
