# Lens Guide

Lens is an AI workspace designed for academic research and structured content work. It brings multi-model chat, academic plugins, file understanding, capability orchestration, and result organization into one continuous workflow. It fits paper reading, literature review, LaTeX writing and polishing, coursework, team knowledge organization, and long-term research memory.

Lens currently exposes academic capabilities through three membership tiers: Plus, Pro, and Max. Plus is suitable for lightweight reading and writing. Pro is better for high-frequency paper reading, PDF deep reading, and LaTeX handling. Max is for heavier research workflows, complex materials, and the full academic capability set.

## What You Can Do with Lens

- Read papers: upload a PDF and quickly extract the problem setting, method, experiments, conclusions, and risks.
- Write and revise: translate, polish, correct, and restructure abstracts, paragraphs, or full LaTeX drafts.
- Chain abilities: connect multiple capabilities in sequence, for example `PDF Deep Reading -> English Polishing` or `Paper Quick Read -> Chinese Polishing -> Mind Map`.
- Build reusable knowledge: turn Word files, Markdown notes, project code, and references into reusable conclusions.
- Prepare deliverables: shape outputs into summaries, reports, presentations, or team-facing materials while checking progress for long-running tasks.

## Plan Snapshot

| Plan | Best for | Academic capabilities | Orchestration |
| --- | --- | --- | --- |
| Plus | Lightweight academic reading and writing | Paper summaries, arXiv summaries, polishing, translation, mind maps, code explanation, BibTeX conversion | Not supported |
| Pro | High-frequency paper reading and manuscript work | Everything in Plus, plus PDF deep reading, PDF / Word batch summaries, LaTeX summary / translation / polishing / correction | Up to 2 steps |
| Max | Heavy research and full study workflows | Everything in Pro, plus the full Lens academic capability set currently available | Up to 3 steps |

For detailed plan boundaries and billing notes, see [Plans and Capability Boundaries](/en/lens/plans).

## Common Workflows

### 1. Quick Paper Reading

1. Start a new conversation and choose a model appropriate for reading.
2. Turn on the `Academic` switch at the bottom.
3. Upload the paper PDF.
4. Choose `Paper Quick Read` or `PDF Deep Reading`.
5. Ask directly, for example: `Summarize the research question, method, experiment setup, and limitations.`

### 2. LaTeX Writing and Polishing

1. Enter `Academic` mode and upload a `.tex` file or the related project archive.
2. Choose the right plugin: `LaTeX Summary`, `Precise LaTeX Translation`, `LaTeX English Polishing`, `LaTeX Chinese Polishing`, or `LaTeX Highlighted Correction`.
3. Add any terminology constraints if you need certain terms preserved.
4. If you are on Pro or Max, chain reading, translation, and polishing into one orchestration instead of copying results between tasks.

### 3. arXiv Lookup and Summaries

1. Turn on `Academic` mode.
2. Choose `Arxiv Summary` or `Arxiv English Summary`.
3. Enter an arXiv identifier such as `1812.10695`.
4. Ask Lens for a summary, key contributions, related-work comparison, or a translated explanation.

## How Lens Is Usually Used

- Standard chat: ask directly in the main input box.
- File-based tasks: upload materials first, then choose a plugin, then add your question.
- Orchestrated tasks: turn on `Academic`, switch to `Orchestration`, and add each capability step in order.
- Output reuse: continue the conversation, copy the result into a paper or report, or turn it into team knowledge.
- Long-running tasks: PDF, Word, LaTeX, long papers, and multi-step orchestration take longer, and the UI shows the current step and progress.

## Who Lens Fits

- Researchers: paper reading, literature review, terminology control, and research handoff.
- Content teams: material understanding, restructuring, expression improvement, and collaboration.
- Students and writers: coursework, reports, translation, polishing, and structure improvement.

The recommended path is to start from [Quick Start](/en/lens/getting-started), then move into [Academic Mode and Plugins](/en/lens/academic-mode) or [Plans and Capability Boundaries](/en/lens/plans) based on the task you actually want to complete.
