AI writing assistant with autocomplete, research, and a Chrome extension
Context-aware sentence completions appear as you type in Gmail, Google Docs, and other sites through the Chrome extension.
Generate a paragraph from a short prompt or rewrite existing text in a new tone while preserving meaning.
HyperWrite Scholar searches millions of scholarly articles so drafts can include factual, properly cited information.

AI reply generator that reads your dating chats and writes what to text back
Drop in a screenshot of a whole conversation or paste the text; the AI reads both sides of the thread, timestamps, and any profile details in frame.
Each generation returns several distinct replies so you can pick the one that fits, rather than accepting or rejecting a single line.
Switch between casual, flirty, witty, and bold, or match the energy of the person you are texting.
Keep one thread per contact so follow-up suggestions remember previous context and what already worked.
