How Solvgent writes one idea for seven networks

A post that works on LinkedIn rarely works on X as-is. When Solvgent drafts for a network, it gives the drafting step two things specific to that network: a maximum length and a short writing instruction. Here is what those are today.

Network by network

Network	The network’s text limit	What drafts are told
Instagram	2,200 characters	An engaging caption, line breaks, a hook in the first line
TikTok	4,000 characters	A short, attention-grabbing caption; casual and trend-aware
LinkedIn	3,000 characters	Professional but human, line breaks, a hook in the first line
Facebook	63,206 characters	Conversational, written to get comments, a question where it fits
X	280 characters (standard accounts)	Punchy and concise; under 280 characters is mandatory
YouTube Shorts	Title 100 characters, description 5,000	A search-friendly description with a short summary of the video
Pinterest	500 characters	Descriptive and keyword-rich; what the viewer will learn or gain

What stays the same on every network

Some instructions apply to every draft, wherever it’s going:

• Your voice. Drafts start from the brand’s Brand Brain: voice notes, pillars, knowledge entries and the preferences you have added. Lessons saved from your edits stay in Brand Brain for you to review.
• Only your facts. Drafts are told to use only facts from your brief and your Brand Brain, and not to invent statistics, results, testimonials or comparisons.
• Hashtags only when relevant. Drafts don’t add hashtags for the sake of it.
• No emoji overload. Emojis are used sparingly.

Why the first line matters

On Instagram and LinkedIn, people see only the start of a post before “more”. That’s why drafts for those networks open with a hook. You see the whole draft, including that first line, before you approve it.

You still decide

These instructions shape the draft. They don’t replace you. A person reviews every post, edits what’s off and approves it before anything publishes. See Publishing and Approvals.
