Which tool is best for grammar checking only?

Grammarly is the clear winner for grammar checking. It catches more errors, explains why they are wrong, and suggests better alternatives. Notion AI and Quillbot have basic grammar features but are not primarily designed for this.

Is Quillbot good for academic writing?

Quillbot is popular among students for paraphrasing research and avoiding plagiarism. However, use it carefully — always review paraphrased text for accuracy. The citation generator is helpful, but double-check formatting.

Do these tools work with Hindi?

Grammarly primarily supports English. Notion AI can understand and generate basic Hindi but works best in English. Quillbot is English-only. For Hindi writing assistance, consider ChatGPT instead.

Is Notion AI worth the extra cost?

If you already use Notion as your primary workspace, the ₹830/mo add-on is worth it. It saves time by generating content, summarising notes, and brainstorming inside your existing workflow.
