Once you've [created a brand voice](/docs/brand-voice/create), Marky and the writing tools can follow its instructions. The voice changes how the text sounds, not what it says: facts, names, and details still come from your request. ## In Marky In the message box, click **+** > **Brand Voice** and pick your voice. Marky's + menu with Brand Voice open, listing None, Example Yoga Studio, and Create a brand voice A megaphone button appears next to **+**. Hover over it to see which voice is on, or click it to switch voices. The message box with a request typed, and the megaphone button next to + showing the tooltip Example Yoga Studio Marky writes in your voice. Marky's welcome email for a new student, with the subject See you on the mat soon, a short list of what to bring, and the lines Every level, every body and Come find us, signed The Example Yoga Studio team The voice stays on for everything you send, in this chat and in new ones, until you choose **None** or reload the page. Name your business in the request when it matters: the voice sets the style, and Marky may take names from your [memory](/docs/marky/memory) otherwise. ## In the writing tools More than 130 tools have a **Tone of voice** field, among them Blog Post, LinkedIn Post Generator, and Instagram Post Caption. They can all use your brand voices. The Instagram Post Caption tool with Tone of voice set to the brand voice Example Yoga Studio, and a Manage voices link * Once you have a brand voice, **Tone of voice** is set to your newest one. Choose another voice from the list. * To describe a tone for one result instead, choose **Custom** and type it, such as "witty" or "professional". * **Manage voices** opens your brand voices in a new tab. An Instagram caption written in the brand voice: Early mornings just got a whole lot softer. Our new Sunrise Flow starts Monday at 6:30 am - we'll save you a spot. Tools read the first 2,000 characters of the voice's instructions, so keep the most important rules at the top. Brand voices aren't available in workflows or on the public tool pages; there, type the tone you want. ## Cost A brand voice doesn't cost anything extra. Marky and the tools use words as usual for what they write. See [Plans and credits](/docs/account/plans-and-credits#words). ## Tips * **One voice per audience.** A voice for customers and one for investors work better than one voice that tries to cover both. * **Fix what you notice.** When results keep doing something you don't want, add a rule to the instructions, such as "No emojis" or "Never promise delivery dates". * **Give facts in the request.** Prices, dates, and names belong in what you ask for, not in the voice. Build one from your website or samples. Reuse good prompts with your voice.
