🔒 Privacy-First — No Sign-Up, 100% Client-Side
Your data never leaves your browser. TextAgent runs entirely client-side with no server, no account, and no tracking. Type sensitive content with confidence — even your saved data stays in localStorage on your device.
🤖 AI Writing Assistant — Local & Cloud Models
Built-in AI with 3 local model sizes + cloud providers — choose Qwen 3.5 Small (0.8B), Medium (2B), or Large (4B) for fully private local inference, or use cloud models (Gemini, Groq, OpenRouter). High-end device warning before 4B download.
📄 Templates Gallery — 109+ Templates, 13 Categories
Start any document in seconds. Browse 109+ professionally designed templates across 13 categories: AI, Agents, Coding, Creative, Documentation, Finance, Games, Maths, PPT, Project, Quiz, Tables, and Technical. AI-powered templates include {{AI:}} tags for one-click document generation and the Games category features 6 instant pre-built games.
💻 Code Execution — Run Python, JS & SQL In-Browser
Turn Markdown into an interactive notebook. Execute code in 6 languages directly in the preview pane — Python (Pyodide), JavaScript, SQL (SQLite), Bash (just-bash), HTML, and Math (Nerdamer). All sandboxed, all client-side.
🎬 Presentation Mode — Markdown to Slides
Present from your Markdown. Add --- separators to create slides, then click Present. Navigate with arrow keys, view speaker notes, switch layouts, and use the overview grid. Choose from 20+ PPT templates with image backgrounds.
📊 Table Spreadsheet Tools — Sort, Stats & Charts
Interactive tables with spreadsheet-level power. Hover over any rendered table to reveal a toolbar with Sort, Filter, Search, Stats (Σ), Chart, Add Row/Col, CSV/MD export, and inline cell editing. Generate bar charts directly from your data.
🎨 Writing Modes & Themes — Zen, Dark & 6 Themes
Your perfect writing environment. Switch between 6 preview themes (GitHub, GitLab, Notion, Dracula, Solarized, Evergreen), toggle dark mode, and enter Zen mode for distraction-free fullscreen writing. Focus mode dims surrounding paragraphs.
📂 Import & Export — 8 Formats In, PDF/HTML Out
Import anything, export everything. Drag and drop files in 8 formats (MD, DOCX, XLSX, CSV, HTML, JSON, XML, PDF) — all converted to Markdown client-side. Export as Markdown, HTML, or smart PDF with intelligent page breaks.
🔐 Encrypted Sharing — Zero-Knowledge Security
Share securely with AES-256-GCM encryption. Choose Quick Share (key in URL fragment, never sent to server) or Secure Share with a custom passphrase. Recipients need the passphrase to decrypt — the server never sees your content or keys.
🛠 Formatting Toolbar — Bold, Lists, Tables & More
Full formatting power at your fingertips. Bold, italic, strikethrough, headings, links, images, code blocks, ordered and unordered lists, tables, and undo/redo — all accessible from the toolbar without memorizing Markdown syntax.
🤖 AI Model Selector — Choose Your Engine
Pick the right model for the job. Switch between 3 local Qwen sizes (0.8B / 2B / 4B) and cloud providers (Gemini, Groq, OpenRouter) directly from the AI panel. Per-card model selection lets you use different models for different blocks.
🔗 Sync Scrolling — Editor & Preview in Lockstep
Keep your place effortlessly. Two-way synchronized scrolling links the editor and preview pane so you always see the rendered output for the line you're editing. Toggle on/off with the link icon.
📑 Table of Contents — Auto-Generated Navigation
Navigate long documents instantly. A clickable sidebar TOC is auto-generated from your headings. Jump to any section with a single click, and the TOC highlights your current position as you scroll.
🎤 Voice Dictation — Speak Your Markdown
Hands-free writing with Markdown awareness. Triple-engine ASR combines Web Speech API, Voxtral Mini 3B (WebGPU, primary, 13 languages) or Whisper Large V3 Turbo (WASM fallback) with consensus scoring. Download consent popup shows model size and privacy info before first use. 50+ voice commands with natural phrases — say "heading one" or "title" for H1, "bold text end bold" for text, "add table" for a markdown table, "undo" to take it back. Auto-punctuation adds capitalization and periods, with LLM refinement when a model is loaded.
🏷️ AI Document Tags — Generate Entire Sections
One-click document generation. Use {{AI:}} for text (with @think: Yes for deep reasoning) and {{Image:}} for AI-generated images. Each tag becomes a card with generate, review, accept/reject, and regenerate controls — all operating independently.
🔀 Template Variables — Dynamic Reusable Documents
Templates that adapt to you. Define $(varName) placeholders in any document, click ⚡ Vars to auto-detect them, fill in the generated table, and apply. Built-in globals like $(date) and $(time) work automatically. 12 templates include variable support.
🔗 Agent Flow — Multi-Step AI Pipeline
Chain AI steps together. Write {{Agent: Step 1: ... Step 2: ...}} in markdown — a pipeline card renders with numbered steps and connecting arrows. Each step's output feeds into the next. Choose a model and search provider per card. Run, review, and accept/reject the combined output.
🐧 Compile & Run — 25+ Languages via Judge0 CE
Compile and execute code inline. Write {{Linux:}} tags with Language: and Script: fields to compile and run C++, Rust, Go, Java, Python, TypeScript, Kotlin, Scala, and 25+ more languages. Output (stdout, stderr, compile errors) appears inline with execution time and memory stats.
📂 Workspace Sidebar — Multi-File Management
Manage multiple files in one workspace. Toggle the sidebar with the File Tree button to see all your files. Create, rename, duplicate, and delete files via right-click context menu. Each file has independent localStorage persistence. Active file highlighting and smooth switching.
🧠 Context Memory — Workspace Intelligence
Give AI access to your workspace. Use {{Memory:}} tags to index workspace files and external folders with SQLite FTS5 full-text search. Add Use: workspace to any AI/Think/Agent tag to auto-retrieve relevant context. Memory Selector dropdown on each card lets you toggle sources. Amber-accented Memory cards show attached files with Folder/Files/Rebuild controls.
❓ Help Mode — Interactive Learning
Learn every feature instantly. Click the ❓ Help button to activate learning mode — all buttons get teal ring highlights. Click any button for a popover with feature name, description, keyboard shortcut, and ▶ Watch Demo button. Demo videos play in a 50% screen panel with fullscreen expand. 16 dedicated demo videos mapped to every toolbar button.
✉️ Email to Self — Share to Inbox
Send documents directly to your inbox. After generating a share link, enter your email in the "Email to Self" section — the document is sent with the share link and .md file attached. Powered by Google Apps Script (free, 100 emails/day). Email is persisted in localStorage for convenience.
💾 Disk-Backed Workspace — Save to Folder
Work directly with files on disk. Click "Open Folder" to connect a local folder via File System Access API. Files are read/written directly to disk with debounced autosave. Refresh from disk for external changes, disconnect to revert to localStorage, and auto-reconnect on reload. Unified action modal for rename, duplicate, and delete with confirmation.
🔌 API Calls & Linux Tags — REST + Compile
Call APIs and compile code from Markdown. Use {{API:}} tags for REST API calls (GET/POST/PUT/DELETE) with response stored in variables. Use {{Linux:}} tags with Language: and Script: fields to compile 25+ languages. Toolbar sections provide quick-insert buttons for API (GET/POST) and Linux (🐧 Linux, 🔷 C++) with overflow dropdowns for more languages.
🏷️ DocGen Preview Editing — Editable Prompts & Steps
Edit prompts and steps directly in preview cards. Use @prompt: for editable AI instructions (bare text stays as a static description label), edit @step: inputs inline in Agent Flow cards, and attach images with 📎 for multimodal vision analysis. All edits sync back to the editor in real-time.
