About QuillAid
Learn about our mission and the technology behind the editor
Our Mission
QuillAid is built for writers, editors, and content creators who want the speed of AI without sacrificing control. We believe AI should assist your writing process, not replace your voice or hide what it changes.
Every feature is designed around transparency: tracked changes show exactly what AI suggests, inline diffs let you review edits line-by-line, and full undo gives you complete control over your document’s evolution.
Core Features
Inline AI Editing
Select any text, describe what you want in natural language, and see a side-by-side diff of proposed changes. Accept, reject, or modify suggestions before they touch your document. No black-box rewrites.
Autocomplete
Fast, context-aware suggestions appear as you type. Accept with Tab or keep writing, autocomplete adapts to your style and never interrupts your flow.
Agent Chat
A dedicated chat interface for brainstorming, outlining, and longer research requests. Ask questions, request drafts, or iterate on ideas without switching apps.
Multi-Format Export
Export finished documents to PDF, Word (.doc), Markdown (.md), HTML, or plain text directly from the toolbar. Formatting, tables, lists, and images are preserved across all formats.
Tracked Changes
Every AI suggestion is logged with full undo history. See what changed, when, and why. Roll back any edit with a single click.
Built for Professionals
We designed QuillAid for teams and individuals who ship content under deadline pressure, product marketers, technical writers, content strategists, and editorial teams who need AI speed without compromising quality.
Whether you’re drafting product launches, investor updates, technical documentation, or blog posts, QuillAid keeps you in control while accelerating the writing process.
Free Tools
Beyond the core editor, we offer free conversion and generation tools for common content workflows:
- File Conversion: Convert between Markdown, PDF, HTML, Word, and plain text without signup
- Content Generation: Generate AI-assisted starter content for blogs, landing pages, and documentation
These tools are free to use and require no account, perfect for quick tasks and one-off conversions.
Technology
QuillAid is built on modern web technologies for speed and reliability:
- ProseMirror: Professional-grade editing framework with collaborative editing support
- Real-time sync: Changes save automatically and sync across devices
- Worker-backed AI: Autocomplete and processing run in background threads to keep the editor responsive
- Privacy-first: Documents stay in your workspace and are only processed when you use AI features
Our approach to AI
We only ship AI features when they keep editors in control. That means every suggestion must be reviewable, reversible, and clearly attributed. We bias toward small, auditable steps instead of one-click rewrites so your team can maintain voice across every asset.
The Agent, inline editor, and autocomplete models run with scoped context windows. We never train on customer documents, and we expose knobs so you can tune tone, length, and aggressiveness without losing oversight.
Editorial principles
- Transparency: Track every change, keep a full audit trail, and surface diffs before publishing.
- Collaboration: Invite stakeholders into the same document with comment threads, approvals, and shared templates.
- Consistency: Use reusable building blocks, prompts, snippets, and conversion presets to maintain voice across channels.
- Speed with safety: Accelerate drafting while preserving review workflows your legal, compliance, or leadership teams depend on.
Who we build for
Our customers span product marketing, customer education, operations, and revenue teams. They share a common thread: shipping high-impact content under deadline pressure. We interview customers weekly, pair on workflow design, and roll improvements into the editor so everyone benefits.
From early-stage startups crafting their first launch narrative to global enterprises coordinating multi-team announcements, QuillAid adapts to the process you already use. Bring your templates, approval matrix, and brand guardrails, we plug in without disrupting the way you work.
Roadmap highlights
- Collaborative review rooms: Shared spaces for legal, product, and leadership to annotate drafts together.
- Conversion automations: Schedule recurring exports for weekly updates and investor reports.
- Custom model tuning: Bring your own training data to personalize tone across departments.
- Deep integrations: Connect to CMS, CRM, and analytics tools so content performance feeds future drafts.
