Privacy

Schriftly

Your text goes directly to your chosen AI provider. Schriftly never sees, stores, or processes your content. No browser extension reading everything you type.

Grammarly

All text is processed on Grammarly's cloud servers. Their browser extension has access to everything you type in your browser. Broad data collection policies.

Pricing

Schriftly

$39 one-time payment for lifetime access with BYOK, or $9/month for the hosted plan. No annual commitment. Most BYOK users spend less than $1/month on API costs.

Grammarly

Free tier with basic grammar and 100 AI prompts/month. Pro costs $12-30/month ($144-360/year). Business plans start at $15+/user/month.

AI flexibility

Schriftly

Choose from 200+ models via OpenAI and OpenRouter — GPT-4, Claude, Llama, Mistral, and more. Switch models anytime for different tasks.

Grammarly

Locked to Grammarly's proprietary AI. No model choice, no transparency about which model is used, no ability to switch.

What it can do

Schriftly

Fix grammar, translate between languages, summarize long texts, rewrite for tone, explain code, or run any custom prompt you create. Unlimited use cases.

Grammarly

Primarily grammar and style corrections. AI writing assistant has monthly prompt limits. No translation. Limited summarization.

Workflow

Schriftly

Select text in any app, press a keyboard shortcut, get instant AI transformation. No pop-ups, no sidebar, no distractions. Review changes with diff view.

Grammarly

Inline suggestions and pop-ups appear while you type. Can be intrusive during focused work. Sidebar takes up screen space.

Bottom line: Grammarly is a grammar checker. Schriftly is a universal AI text assistant that also fixes grammar — plus translates, summarizes, rewrites, and runs any prompt you create. If privacy, pricing, or AI flexibility matter to you, Schriftly is the better choice.
