WordWand vs Stanza: Which Mac Grammar Checker Is Better in 2026?

WordWand and Stanza are both native Mac apps that fix grammar in any application. That is where the similarity ends. They represent two very different philosophies: Stanza is a privacy-first, offline grammar checker that does one thing well. WordWand is a full AI writing toolkit that does many things — grammar, dictation, translation, text-to-speech, AI generation — in one app.

The right choice depends on whether you need a focused grammar tool or a complete writing assistant.

How They Work

Stanza

Stanza is a native macOS app that checks grammar, spelling, punctuation, and style in any Mac application. It runs entirely offline by default using local AI models (Llama 3.2 3B, Qwen 3 1.7B) on Apple Silicon Macs.

Your text never leaves your machine unless you explicitly enable Stanza Cloud (optional, subscription-only) or connect your own API keys from OpenAI, Anthropic, or Google.

Stanza supports 90+ languages for grammar checking and works in Safari, Chrome, Mail, Slack, Notion, Pages, Notes, and all other Mac apps.

Pricing is aggressive: $2.99/month or $14.99 lifetime. Currently free during early launch.

WordWand

WordWand is a native macOS menu bar app that goes well beyond grammar. Select text in any app, press one keyboard shortcut, and choose from grammar correction, tone adjustment, AI text generation, translation in 40+ languages, task extraction, or custom AI prompts.

WordWand also includes voice dictation — speak into any app — and text-to-speech with podcast mode — listen to any text read aloud, including as a two-person conversation. An iOS app with keyboard extension is coming soon.

WordWand has a free tier (5,000 words/month, all features) and Pro at $10.99/month.

Key Differences

Offline Processing and Privacy

This is Stanza's defining feature. Everything runs on-device by default. Your text is processed by local AI models on your Mac. Nothing is uploaded, tracked, or shared. For users handling sensitive content — legal documents, medical records, confidential business communications — this is a meaningful guarantee.

WordWand processes text via cloud-based AI models. It does not store text on servers and deletes audio immediately after transcription, but your content does leave your Mac during processing.

If absolute privacy with zero cloud involvement is your requirement, Stanza is the clear choice.

Feature Scope

This is where the two apps diverge most dramatically.

Stanza does: grammar, spelling, punctuation, style suggestions.

WordWand does: grammar, spelling, tone adjustment, AI text generation, AI rewriting, translation (40+ languages), voice dictation, text-to-speech, podcast mode, task extraction, custom AI prompts, and Ask AI.

Stanza is a grammar checker. WordWand is a writing assistant. If you only need grammar and style fixes, Stanza is leaner and focused. If your writing workflow involves any combination of dictation, translation, content generation, or listening to text, WordWand covers more ground.

AI Text Generation

WordWand can generate text from scratch — draft emails, write replies, create content, summarize documents — using its AI writer and custom prompts.

Stanza corrects existing text. It does not generate new content, rewrite passages in different styles, or create summaries.

Voice Dictation

WordWand includes built-in voice dictation. Speak into any app, and the transcribed text is ready for immediate grammar correction or tone adjustment.

Stanza does not offer voice dictation.

Translation

WordWand supports inline translation in 40+ languages. Select text, translate, the result replaces the original.

Stanza does not have a dedicated translation feature.

Text-to-Speech

WordWand reads any selected text aloud with natural voices. Podcast mode converts text into a two-person discussion.

Stanza does not offer any audio output.

iOS App

WordWand is building an iOS app with a keyboard extension — coming soon.

Stanza is Mac-only and requires Apple Silicon (M1 or newer) with macOS 14+.

Pricing

Plan	WordWand	Stanza
Free	5,000 words/month, all features	7-day trial (currently free during launch)
Monthly	$10.99/month	$2.99/month
Lifetime	—	$14.99 one-time
Annual cost	$131.88/year	$35.88/year (or $14.99 total for lifetime)

Stanza is the most affordable option in this comparison by a wide margin. The lifetime plan at $14.99 is exceptionally cheap for a native Mac app with local AI processing.

WordWand costs more but includes far more features. The free tier (5,000 words/month, no time limit) lets you evaluate without commitment.

System Requirements

WordWand runs on macOS 13+ and supports both Apple Silicon and Intel Macs.

Stanza requires macOS 14+ and Apple Silicon only (M1/M2/M3/M4). Intel Macs are not supported — the local AI models require the Neural Engine in Apple Silicon chips.

Who Each App Is For

Stanza fits best if you want a focused, privacy-first grammar checker that runs entirely offline. If your main use case is fixing grammar and spelling in everyday writing, and you want the peace of mind that your text never leaves your Mac, Stanza at $14.99 lifetime is an exceptional value.

WordWand fits best if you want a complete writing assistant — grammar is just the starting point, and you also need dictation, translation, AI generation, and text-to-speech. WordWand replaces multiple single-purpose tools with one app.

The two apps are complementary in some ways: Stanza for quick, private grammar fixes on sensitive text; WordWand for everything else.
