Social Media
Social media is the part of book marketing most authors don’t want to do, probably shouldn’t do a lot of, and also can’t entirely avoid. If your book has an audience hook that’s visual, promotable, or meme-able, you’re going to spend some time on social media. If you’re indie and launching a book, you’re going to spend some time on social media. If you’re traditionally-published and your publisher wants you to help launch, you’re going to spend some time on social media. The only authors who can cleanly skip it are the ones with enough established platform elsewhere (established newsletters, existing audiences, publisher-backed PR) that they don’t need the social media pipeline. Everyone else needs at least a plan for what to post and when. The Social Media subtab is Ishvana’s place for that plan.
It’s not a social media scheduling tool. It doesn’t connect to Twitter’s API to post for you. It doesn’t track your follower counts. What it does is help you draft the posts, organize them into a launch schedule, and pull the specific hooks from your book that will actually make the posts work. Drafting social posts in a vacuum is how most authors end up with bland filler content. Drafting them next to your manuscript and your Legendry lets you pull real hooks from your real book.
Five platforms, different shapes
Section titled “Five platforms, different shapes”Each platform has its own constraints and conventions, and the subtab drafts for five of them with enforced character and hashtag limits per platform:
| Platform | Character limit | Hashtag limit |
|---|---|---|
| Twitter / X | 280 | 5 |
| 2,200 | 30 | |
| 63,206 | 10 | |
| TikTok | 4,000 | 10 |
| Bluesky | 300 | 10 |
Twitter / X
Section titled “Twitter / X”280 characters per post. Thread-friendly — long-form ideas get broken into threads where each tweet links to the next. Hashtags are less important than they used to be. Image-in-first-tweet gets more reach than no image. Replies and quote-retweets are the most effective growth mechanism. Book Twitter remains a real community even as X’s overall health has declined.
The subtab drafts single tweets, thread starters, and full multi-tweet threads. For threads, it can pull cliffhangers from your manuscript, worldbuilding reveals from your Legendry, or character-arc beats from your Plot Studio and turn them into thread hooks.
Visual-first. Caption is text, but the image is what sells the post. Captions can be long (up to 2,200 characters) but the first line gets cut off on feed displays so the hook has to fit in that first line. Hashtags are more relevant than on Twitter — you get up to 30 per post. Stories and Reels are separate formats with their own rules.
The subtab drafts captions, not images — Ishvana doesn’t generate images. But it can suggest what kind of image should accompany a given caption (“a shot of your book cover with a specific atmospheric filter,” “a character portrait from your Visual Studio gallery,” “a map of your world from the Map Studio”). The caption and the image suggestion travel together.
The largest character limit on the list, at over 63,000 characters per post. In practice you’d never write that long a post — Facebook engagement drops sharply past 300-500 characters. The large limit exists because Facebook supports long-form content if you want it. For most author marketing, Facebook posts are 2-4 paragraphs with an image or link.
Facebook’s hashtag limit is 10, but hashtags on Facebook have never mattered the way they do on Instagram. Optional at best.
TikTok
Section titled “TikTok”Short-form video. The subtab doesn’t generate video, but it drafts the script and the hook. BookTok is a real discovery channel for romance, fantasy, and YA especially, and the videos that work are almost all formulaic — cover reveals, tropes listings, character aesthetic montages, “POV: you’re the character in this scene” setups.
The subtab knows several of these formulas and can draft a TikTok script for your book in any of them. The scripts are short — 30 seconds to 2 minutes of spoken content — and include a hook, body, and call-to-action. The 4,000-character limit on TikTok posts refers to the caption, not the spoken script.
Bluesky
Section titled “Bluesky”The newest platform on the list and the most promising for book-adjacent communities. 300 characters per post (slightly more than Twitter). No algorithmic feed by default — chronological posts from people you follow, which means engagement depends on being genuinely present rather than optimized for any algorithm.
BookSky (the book community on Bluesky) is small but fast-growing, and tends to welcome authors who participate as readers rather than just promoting their own work. The subtab drafts Bluesky-appropriate posts but the format is similar enough to Twitter/X that most Twitter posts also work on Bluesky with minor tweaks.
What the subtab drafts
Section titled “What the subtab drafts”Regardless of platform, the subtab can draft six types of social content:
- Hook posts. Single posts designed to stop scroll. The hook is pulled from something specific in your book — a twist, a character beat, a piece of worldbuilding, a line of dialog. Not generic “check out my book” content.
- Character aesthetic posts. A character from your Legendry paired with descriptive language that captures their vibe. Most useful for romance, YA, and character-driven fiction.
- Worldbuilding hooks. A piece of your Legendry presented as intrigue. “In the world of [X], there are [Y] kingdoms ruled by [Z] — here’s why that matters.” Works for secondary-world fantasy and sci-fi.
- Excerpt posts. A carefully chosen passage from your manuscript, usually under 200 words, that works as a standalone hook. Finding the right excerpt is the hardest part — the subtab can scan for passages that have strong opening lines, high tension, or clean character voice.
- Trope posts. A list of tropes your book hits. Crucial for romance. Useful for other genres too but less culturally weighty.
- Behind-the-scenes posts. Author commentary on a choice you made in the book — why a character is named something, what inspired a location, what got cut. These posts don’t sell books directly but build the relationship between reader and author over time.
Each type has a drafting template, and generating a draft runs Hawken with the template plus your project context.
Scheduling and rhythm
Section titled “Scheduling and rhythm”A launch campaign typically wants posts at specific cadences. Too infrequent and the campaign loses momentum; too frequent and you spam your followers and they mute you. The subtab has a launch schedule builder that helps you plan the cadence without the math.
You set the launch date, tell the subtab how aggressive you want the campaign to be (light, moderate, heavy), and it generates a schedule of post drafts spaced across the weeks leading up to launch and the weeks after. Each post in the schedule is a specific post type (hook, excerpt, character aesthetic, behind-the-scenes) and the schedule mixes them so you’re not just doing one type repeatedly.
The scheduling isn’t automated — you still post manually, on your own time, when it fits your actual calendar. What the schedule gives you is a plan that you can work from so you’re not every morning asking “what should I post today?”
What the subtab isn’t doing
Section titled “What the subtab isn’t doing”- No auto-posting. Ishvana doesn’t have your social media credentials. It doesn’t push to Twitter, Instagram, or anywhere else. You post manually by copying from the drafts.
- No engagement tracking. The subtab doesn’t know how many likes your tweets got. For analytics, use each platform’s native analytics.
- No follower data. Same reason — no API credentials, no data access.
- No DMs or comments. The subtab only handles outgoing post drafts, not incoming engagement.
- No platform-specific tricks you’re supposed to know. Every social platform has its own little optimization tricks that shift every six months. The subtab knows the general conventions but it isn’t a dedicated social media optimization tool. If you want to obsess over the algorithm, you’d use a specialized tool like Buffer, Later, or Hootsuite for that part.
The subtab is a drafting and planning surface. Engagement, posting, and platform-specific optimization happen elsewhere.
When to use it
Section titled “When to use it”A few honest uses:
Launch weeks. When you’re in the final push before a book release and you need to produce real social content daily, the subtab is the fastest way to draft that content without burning out.
Content batching. When you’ve decided to set aside a Saturday to write a month’s worth of social posts in one sitting, the subtab helps you batch-draft instead of staring at blank text boxes for hours.
Getting unstuck. When you know you should be posting but can’t think of what to post, the subtab can generate a dozen different hooks in five minutes and you can pick the ones that feel right.
Campaign planning. When you want to think strategically about how a launch should unfold across weeks of posts rather than just winging it, the schedule builder gives you structure to push against.
What the subtab isn’t for
Section titled “What the subtab isn’t for”- Authentic daily presence. If you’re building a social following over years, the subtab won’t help with that — that’s about being genuinely present on the platform, not about drafting more posts.
- Personal brand work. The subtab drafts posts about your books, not about you. For personal-brand-style content, you’re on your own.
- Community management. Responding to fans, running contests, moderating discussions — the subtab is purely about outgoing content.
