Guide
GemmaLens turns academic papers, technical documents, and subtitles into source-grounded language lessons. The goal is not to replace reading with translation; it is to help you read the next source with less support.
Paper reading
Start with the original source. GemmaLens opens the first prepared lesson quickly, then continues preparing the rest while you read.
Upload or paste
PDF, DOCX, markdown, text, or transcript becomes a source document. PDFs keep the original file when available.
Read beside the source
For PDFs, the original page stays visible while the learning panel explains the current section.
Read while it prepares
The first page appears immediately. By default, GemmaLens prepares every page section in the background to reduce waiting.
Build the paper map
As sections finish, GemmaLens builds an outline of argument flow, concepts, terms, and expressions.
Save what matters
Save concepts, terms, expressions, and hard sentence patterns separately so review can stay targeted.
Local-first preparation
GemmaLens does not wait for a whole-paper pass before becoming useful. It breaks long sources into small jobs, which lets local Gemma models prepare useful lessons without sending your paper to a remote reading service.
ThinkPad / small local model
Runs the same section pipeline with lower memory pressure; background preparation hides per-section delay.
Mac M1 Max
Fast local inference can prepare many sections while the learner reads the visible page.
Mobile / edge demo
The product story still works on constrained devices because work is split into small page-section jobs.
Learning objects
GemmaLens separates different kinds of help so the lesson does not become a wall of generated text.
Key ideas
Ideas needed to follow the paper's argument, such as the method, objective, ablation, or benchmark setup.
Terms
Source-grounded vocabulary and domain terms worth saving only if they are unfamiliar or repeated.
Reusable expressions
Academic moves such as contrast, limitation, method setup, result claims, and conclusion language.
Sentence patterns
Dense structures are simplified and explained so the learner can read similar sentences later.
Translation
Use Translate for short passages. Use Documents or Video for real study, because those workspaces preserve source context, repeated terms, and review history.
Video study
Video mode treats subtitles as timestamped reading material. It is strongest when you have a reliable English subtitle file or stable public transcript.
Local subtitle study
Open a local video and attach English subtitles. The timeline follows playback and supports line-level study.
Live cues
While watching, GemmaLens surfaces lightweight vocabulary and phrases from the current subtitle window.
Scene lessons
Analyze a short scene for concepts, spoken expressions, and source-grounded review items.
Recap watched part
Use deeper recap after watching a larger segment, then save useful terms and expressions for review.
Reading levels
B1
Needs help with main ideas, academic phrases, and dense grammar.
B2
Can read general academic text with support for domain words and long sentences.
C1
Can read research writing but benefits from structure, nuance, and reusable expression notes.
C2
Focuses on precision, rhetoric, field-specific phrasing, and paper-level argument flow.
Domain-heavy
Difficulty comes mainly from specialist concepts rather than grammar.
