AI email tool comparison - Word.now vs Fyxer, Superhuman, SaneBox and more
Six side-by-side comparisons covering features, pricing, inbox access requirements, and which tool wins for different use cases. Find the right fit before you sign up for anything.
Most AI email tools promise the same thing: less time in your inbox. The differences that actually matter are narrower. Does the tool write replies that sound like you, or does it produce generic text you have to rewrite anyway? Does it require ongoing access to your inbox - Reading every message, storing thread history - Or can it work from what you paste in? And what does the free tier actually give you, versus what gets paywalled immediately?
This table compares Word.now, Fyxer, Superhuman, SaneBox, Gemini for Gmail, and Microsoft Copilot across four dimensions: feature presence, free tier quality, inbox access requirements, and price. Word.now's free reply tool requires no inbox connection and no account - That distinction is noted where it affects the comparison. For the broader market map, see the Word.now alternatives guide.
