Proofly uses Chrome s on-device AI to check spelling, grammar, punctuation and style everything happens locally, no text sent to any server. That s great for privacy, but I want to make sure it s also great for quality and speed.

If you try Proofly (or even just imagine a local-only tool in your stack):

• How do the suggestions compare to your current grammar checker (Grammarly, LanguageTool, etc.)?

• Are they accurate and helpful enough for real-world use (emails to clients, docs for your team, public posts)?

• Is the speed acceptable, slower, or surprisingly fast vs what you re used to?

• In which cases would you still fall back to your existing cloud tool?

Right now, Proofly focuses on core proofreading: catching spelling, grammar, punctuation, capitalization and similar issues directly in your browser, all on-device.
But local AI can go much further, and I d love your help shaping the roadmap:

• What would you want next from a privacy-first writing assistant?

  • Smart rewrites (shorter/longer, clearer, simpler)?

  • Tone shifts (more formal, more friendly, more confident)?

  • Templates/snippets for recurring emails or support replies?

  • Multilingual help (translate + proofread in one go)?

• Which features are nice to have vs must have before I switch from my current tool ?

• Any workflows where having all of this fully local would be a game changer?

Reply with your wish list (and your role: dev, founder, PM, support, legal, etc.).
This thread will be my go-to reference when prioritizing what we build after launch

I m working on Proofly, a privacy-first, on-device writing assistant (think Grammarly-style help, but everything runs locally in your browser using Chrome s built-in AI).

I d love to understand where privacy around writing really matters for you so we can prioritize the right use cases and integrations.

• Do you care most about privacy in emails (Gmail/Outlook), instant messages (Slack/Teams/Discord), helpdesk tools, CRM notes, or docs (Notion/Google Docs/Confluence)?

• Are there specific scenarios where you never want your text to leave your machine (legal, HR, therapy, medical, investor updates, etc.)?

• If you re comfortable sharing, which tools are you using today in those contexts?
