Where Grammarly is stronger
Free web editor flagged deliberate errors (Verb problem, Correct pronoun, Rephrase, Use the right word, plus and/sound/visitor/your/feel) without demanding a card
Suggestions in a few seconds after paste; applied weather→whether and saw score move 55→61 with text visibly updated
Hotmail accepted despite Work or school email label; Outlook verify ~1 min; No, thanks exits the 10-day Pro CTA
Where Typeahead still wins
Private by construction, not by a settings toggle
Latency feels like the OS, not like an API
One job, finished
Notes
Grammarly Free web Docs flagged a 56-word messy draft (All 10 / Grammar 9 / Clarity 1, score 55) and applied weather→whether plus a weird its→it swap; score rose to 61 with no card required. Pro CTAs (Try Pro for $0 / 10-day free) stay loud; AI rewrite/detector/plagiarism stay locked. Final rating: 4/5. Full review: https://toolifynav.com/blog/grammarly-review
AI inside the wiki you already use: summaries and drafts next to the source page.

Notes
Notion AI is an amplifier of the workspace you have, including the ugly parts. ChatGPT and Claude remain better for long outside documents. Superhuman remains better for inbox. Typeahead remains better for local caret completion.
Turn it on after teamspaces and guest rules are boringly correct. If you cannot explain who can see a page, you are not ready for a button that summarizes it. Confirm which AI features your plan actually includes — marketing pages and the seat you bought still drift.
Paid, keyboard-first inbox for people who treat email like a sport and will learn the shortcuts.
Paid subscription after onboarding

Overlaps the same job as Typeahead, especially Operators with a high email athletic load.

Notes
Superhuman is for people whose bottleneck is the inbox and who will train. Gmail plus Typeahead is cheaper if the bottleneck is a sentence. HubSpot is the system if the bottleneck is the pipeline.
Block the training hour or do not buy it. Confirm which mailbox providers and shared inboxes you actually use. Do not roll it out as a status symbol to people who live in Slack.
Count the threads you answer in a real day. If the number is small, Superhuman is a luxury. If the number is the job, pay and train. Confirm shared inboxes and the actual mailbox provider before you gift seats.
