Grammarly vs Knowee

Grammarly

Still the default for catching mistakes inside other people's software, but the free tier has quietly become an AI-prompt meter and the honest price is $30 unless you commit to a full year.

Pros

• +Runs inside the apps people already write in rather than as a separate editor
• +Free tier still covers spelling, grammar and tone detection with no time limit
• +Pro folds in plagiarism and AI-text detection that rivals charge for separately

Cons

• −The $12 headline is the annual rate; paying monthly costs $30
• −Free AI allowance is 100 prompts a month and depletes quickly
• −No public API, so it cannot be embedded in another product
• −Enterprise pricing is not published anywhere on the site

Knowee

Knowee's specific focus on outlines and citation checking, rather than just generating a finished essay outright, is a more defensible pitch for a tool marketed at students worried about academic integrity. The free plan is real, but this is still fundamentally an essay-assistance tool, and how an individual instructor or institution treats its use is outside the product's control.

Pros

• +Distinct focus on outlines and citation verification rather than just full essay generation
• +Available both as a website and a Chrome extension
• +Writing can start for free before any paid plan

Cons

• −Company discloses an operating entity name but no confirmed headquarters country
• −Plan prices are hidden until you sign in, so the cost cannot be compared up front
• −Use of any AI essay tool carries academic integrity risk that depends entirely on institutional policy, not the product
