LighTL - AI Translator Built for Novels, Not Sentences

AI translator built for novels, not sentences

LighTL reads your novel sequentially from Chapter 1—remembering characters, context, and narrative threads across every chapter.

Without context, AI gets confused

Here's what happens when the AI doesn't remember who speaks how:

Scene Context

The protagonist returns to the forest. Ai (a girl) ran out to greet him. Nina is explaining why Ai left the safety of the forest.

Why this matters

LighTL remembers that Nina consistently refers to the protagonist as "あんた" (anta). With this context, LighTL correctly identifies the speaker as Nina. The competitor translated without character-specific context and misidentified the speaker.

Try it yourself: Click the expand buttons in the LighTL panel to see the original Japanese, speaker identification, and translator notes. This is the actual UI you'll use in the app—what you see here is exactly what you get.

We trade cost for comprehension

Three approaches to translating novels—understand the trade-offs:

Translation Quality
Cost Per Chapter
Machine Translation
~Free

Machine Translation

Google Translate, DeepL, etc.

General-purpose translation. Fast and cheap, but not designed for long-form fiction.

  • Instant translation
  • Almost free
  • No context across chapters
  • Inconsistent terminology
  • Not optimized for fiction

LLM-powered with glossaries

Better than basic MT, but glossaries are just dictionaries—the AI doesn't understand context or narrative.

  • Consistent term translations
  • Better prose than MT
  • No narrative understanding
  • Glossaries = word mappings only
  • Each chapter in isolation

The trade-off

Free MT works for getting the gist. Glossary-based AI improves consistency. LighTL trades cost for comprehension—the AI actually understands what it's reading, not just pattern-matching words.
