Tooltips AI

Tooltips AI is a browser plugin that explains highlighted words in text and answers follow-up questions in over 100 languages. Instead of copying text into another tab and pasting it into a chatbot, you select a word or passage and get an explanation in place, right where you are reading. It also supports PDF documents, so the same workflow works while reading reports and papers. The product is free to use and does not require registration, which lowers the barrier to trying it.

- Highlight a word and read an explanation in place.

- Ask follow-up questions about the passage.

- Read content in over 100 languages.

- Use the same workflow inside PDF documents.

- Stay on the page instead of switching tabs.

- Readers working through multilingual content.

- Researchers reading foreign-language papers.

- Language learners building vocabulary in context.

Explanations depend on context, and a short highlight can return a generic answer that misses the meaning in that specific sentence. The plugin needs browser permissions, and free availability can change. For formal writing, translation, or citation work, verify definitions against a proper dictionary rather than relying on a tooltip. Features and interface details may change between versions, so review the latest notes on the page before you start. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work. Save a backup of the original file before large batch jobs, and keep an exported copy of key results in case the page or service becomes temporarily unavailable.
