SigmaNote: AI-Powered, Editable, Searchable Notes from Files/Links

Introducing SigmaNote: Your AI-Native Note-Taking Engine

SigmaNote isn’t just another note app — it’s an intelligent layer between you and your information. Whether it’s a dense research paper, a client pitch deck, a YouTube tutorial, or a long-form article, SigmaNote instantly transforms raw digital content into rich, human-editable, AI-orchestrated notes. Built for thinkers, learners, and doers, it merges capture, comprehension, and recall into one seamless flow — turning passive consumption into active knowledge building.

How SigmaNote Works — In Three Effortless Steps

First, import: drag a PDF, paste a URL, forward an email, or drop a video link (including YouTube). Second, convert: with one tap, SigmaNote extracts key ideas, structures them in clean, semantic Markdown, and preserves source fidelity — so you can toggle between AI summary and original context anytime. Third, engage: search across all your notes in seconds, ask natural-language questions (“Compare these two proposals”), generate action items, or chat across documents to uncover hidden connections.

FAQ from SigmaNote

What is SigmaNote?

SigmaNote is a next-generation knowledge assistant that turns static files and links into dynamic, editable, and AI-interactive notes. It bridges the gap between information ingestion and intelligent application — helping you retain more, think deeper, and act faster — all within a single, secure, Markdown-native environment.

How to use SigmaNote?

Start by importing any supported source — whether it’s a webpage, PDF, presentation, or video. SigmaNote processes it intelligently, generating structured Markdown you can refine, annotate, or expand. Then use the built-in chat to interrogate your notes, synthesize insights across sources, or convert ideas into drafts and tasks — all while retaining full traceability to the original material.

Is SigmaNote free to use?

Yes — the free Starter plan includes 20 monthly imports, 15 AI interactions, and 1 GB of encrypted storage. No credit card required. Upgrade anytime for unlimited conversions, priority AI, advanced search filters, and team collaboration features.

What file types and links can I import?

PDF, DOCX, PPTX, XLSX, EPUB, plain text, web URLs (full-page extraction), YouTube videos (auto-transcribed), Gmail messages, Dropbox files, and iOS Share Sheet integrations. We’re actively expanding support for Notion, Slack, and Figma — with roadmap updates shared monthly on Discord.

How secure is my data and chat history?

Your data is yours — end-to-end encrypted at rest and in transit (TLS 1.3 + AES-256). SigmaNote never trains its models on your content, sells your data, or shares it with third parties. You own full deletion rights: remove individual notes, original sources, or entire chat histories — permanently and instantly.

Can I upgrade, downgrade, or cancel anytime?

Absolutely. All subscriptions are managed directly through the App Store or Google Play. Changes apply at the start of your next billing cycle — and you retain full access to all features and credits until then.

How do I cancel my subscription?

Go to your device’s Settings → [Apple ID / Google Account] → Subscriptions → SigmaNote → Cancel Subscription. Your access remains active through the end of your current period — no prorated refunds, but no surprises either.

How do I get help if I run into issues?

Our fastest support channel is Discord, where engineers and power users respond in real time. For sensitive or account-specific requests, email [email protected]. We aim to reply within 4 business hours.
