Riffwise

First you install the extension from the Chrome Web Store and sign in from Riffwise Settings. There you can set your preferred voice, reply length (short, medium or detailed), language and emoji use, and add your own writing instructions or a personal style note.

Second you open the conversation you want to answer and right-click inside a supported reply box. The menu offers Write a reply or Create quote text. Riffwise can also be started from its toolbar button or a keyboard shortcut, and it only runs after you choose one of these actions.

Third Riffwise reads the conversation. On X it tells the post you are replying to apart from the original post, and can include attached images when a caption alone is not enough. In Gmail it identifies the email being answered and uses recent thread context. The detected source text is shown, along with whether an image is included, before generation.

Finally you review the draft, edit any words, and insert it. In Gmail the reply is inserted before your saved signature. You decide whether to post or send it.

• •Reply Drafts - Answers the post, chat message or email you are viewing, using the relevant conversation so the reply fits what was said.
• •Quote Text - Writes a short take of your own to go with a quote post, which you then edit.
• •Voice and Rules - Saved settings for tone, length, language and emoji, plus your own writing instructions, apply to every draft.
• •Rewrites - Selected text can be improved for clarity, grammar, tone or length from the same right-click menu.
• •Site-Aware Context - Dedicated context detection for X posts and chats, LinkedIn, Threads, Bluesky and Gmail, including image context on X.
• •Nothing Sends Itself - Drafts are inserted through each site's own editor, and Riffwise never clicks Post or Send.

Riffwise suits people who reply often on X, Threads and Bluesky and want a starting point that sounds like them rather than a generic AI answer. Creators and professionals building an audience can use the quote feature to add their own commentary to posts they share, and the voice settings keep a consistent style across replies.

It also fits people who handle a lot of email in Gmail in the browser and want a first draft that already reflects the thread they are answering, inserted above their signature. Because the extension reads the conversation itself, users who are not comfortable writing prompts can still get context-aware drafts.

It is not for mobile-only users, since it needs desktop Chrome, and it is not an autopilot: every draft is reviewed and posted by hand. The free plan covers 40 successful generations a month, which suits occasional use, while Pro raises that to 500 for daily replying.
