LowLighter Guide

The default mode. Sends your selection to the AI and returns a direct answer. Best for questions, problems, and general analysis.

Condenses long selections into concise summaries. Perfect for articles, documentation, emails, and dense content.

Translates the selected text into your chosen target language. You can change the target language from within the app. Supports 35+ languages including Chinese, Japanese, Korean, Arabic, Hindi, and all major European languages.

Breaks down complex content into a clear, step-by-step explanation. Great for code, math, diagrams, and technical material.

Rewrites the selected text in a cleaner, more polished way. Useful for improving drafts, emails, essays, or any written content.

Applies your saved instruction to the selected content. Use it to define a specific task, format, tone, or point of view instead of choosing a fixed mode.

Automatically analyzes your selection and routes to the best engine. If the content is pure text, it uses Fast (free). If it contains images, charts, or complex layouts, it uses Vision. This is the recommended setting for most users.

Uses OCR to extract text from your selection, then sends it to a text-based AI model. Faster and does not count toward your Vision limit. Works best with clean, readable text.

Sends a screenshot of your selection directly to a vision-capable AI model. Understands images, handwriting, diagrams, charts, code with syntax highlighting, and complex layouts. Each use counts toward your monthly Vision limit.

The ultimate invisibility suite. When Phantom Mode is active, the entire app shifts to a purple theme to remind you it's on. Includes:

• Content Protection hides LowLighter from screen recordings and screenshots so only you can see it.
• Dock / Taskbar Hiding removes LowLighter from the Dock (macOS) or Taskbar (Windows) so it runs completely from the system tray.
• Minimal Overlay provides faster, less detectable overlay animations with reduced visual footprint.

Every user gets a free 15-minute Phantom invisibility trial. Full Phantom Mode is a Pro exclusive feature.

Delivers the AI response directly into your active text field as natural typing instead of a paste. This means:

• Nothing touches your clipboard
• Appears as if you typed it yourself
• Works with any text field, input box, or document editor

Your hotkeys stay completely private. Other apps on your system cannot detect when you activate LowLighter, so your workflow remains yours alone.

A separate browser for Agent

Website tasks open in an Agent browser window using Chrome or Edge. It has its own LowLighter profile, so Agent does not work inside your personal browser tabs. No extension is required. Its virtual cursor stays inside that browser and does not move your system pointer.

The browser keeps Agent tabs and user-completed sign-ins between turns. If a site asks for a password, passkey, verification code, CAPTCHA, or consent, Agent pauses in the same tab. Finish the private step yourself, return to LowLighter, and ask Agent to continue. Some providers may still refuse an automated browser.

Choose how actions are approved

Ask before running

Review an action before Agent reads or changes files, runs a command, or inspects the screen.

Full access

Let Agent continue without asking each time. Operating system permission prompts and administrator approval still require you.

Stay in your current app

Summon Agent and type without switching away from the app you are using. Agent may bring its browser or another app forward when the task needs it, but writing your request in the Agent overlay does not take over your current app.

Conversations, instructions, and attachments

Start a new conversation, return to an earlier one, or delete a conversation from the history menu. Saved Instructions tell Agent how you prefer it to work and remain available when its windows close. You can attach images or files with the attachment button or drag them onto the input. Up to two attachments can be prepared with one request.

Phantom for Agent

Pro users can turn on Phantom for Agent, making the Agent overlay invisible to screenshots, recordings, and screen shares while it remains fully visible and interactive for you.

Agent credits

Pro includes 500 Agent credits each month. Included credits are used first. You can add 250 credits for $5, 500 for $10, or 750 for $15 in Agent settings. Purchased credits carry over until used.

Scheduled tasks

On macOS, Agent can save recurring or one-time tasks, run them now, pause them, and remove them. Ask before running still applies. Scheduled tasks are not available in the current Windows build yet.

Ask Assist without starting a session

Type a question in the top field and press the arrow, or use your Assist shortcut. This is ordinary screen-aware help. Meeting AI can also answer basic questions about the Meetings overlay, explain what a control does, and describe what Meetings can do. It does not use a live transcript until you start a session.

Start live listening

Press the waveform button labeled Start Audio Session. Meetings begins listening to the microphone and system audio and builds a live transcript. Starting the session does not open the transcript automatically. The listening status appears in the bottom-left footer, and Transcript or View Transcript opens it.

Use Assist during the call

Press Assist for help based on the newest transcript, your selected Meeting Mode, and your screen when Use screen context is enabled. The answer appears in the Meetings conversation. If no live session is active, Meetings uses General help instead.

Pause or finish

Use the two-bar button next to Done to pause. It changes to a resume control while paused. Done ends the session and saves the completed transcript to History.

Choose a mode and context

Open the four-square button for General, Interview, System Design, Coding Interview, Behavioral Interview, or Custom. The selected mode guides live Assist only. Meeting Controls lets you enable screen context, turn Invisibility on, select the transcription language before starting, and edit global shortcuts.

History and follow-up

History contains finished transcription sessions, not ordinary Assist questions. Search, open, resume, or delete a saved session. New Chat clears the current ordinary Assist conversation without ending a live listening session.

Ask about a completed transcript

Open a completed session and use Ask me anything about this transcript to request notes, feedback, key points, or follow-up answers. LowLighter keeps the chat with that transcript and separates it from live sessions and ordinary Assist chats. Deleting the transcript also deletes its chat.

Reference files

Non-General modes can use editable guidance and up to two PDF, DOCX, TXT, or MD reference files. Files are indexed once and relevant excerpts are used for Assist.

Go to Settings → Offline AI and download the model. Once downloaded, enable Offline Mode. LowLighter will switch to Fast Engine automatically and route all inference locally. Your Vision quota is not consumed while offline mode is active.

The modes included with your plan are available offline. Basic and Pro include all five core modes: Answer, Explain, Summarize, Rewrite, and Translate. Pro also includes Custom Prompt, which applies your saved instruction to text extracted locally from the selection. Only the Fast Engine is available since OCR runs locally.

Auto Engine and Vision Engine require a cloud connection. If you need to process images, diagrams, handwriting, or math notation, turn offline mode off and use Auto or Vision.
