Instagram, LinkedIn, TikTok: one draft, four tones

The same message doesn’t read the same on LinkedIn and TikTok. On one, people scroll in a blazer between emails. On the other, they’re lying down, sound off, and you have less than a second. Claiming “one post is enough” saves five minutes and costs fifty in empty comments.

Kanaux starts from a single draft, then helps you adapt length, hook, and CTA per connected network. The substance (your offer, proof, point of view) stays. The form changes: rhythm, address, emoji or not, link or not.

What actually changes

It isn’t the hashtag count. It’s the reading contract. LinkedIn promises a useful idea for professional attention. Instagram promises an image and a tone. TikTok promises an immediate emotion. A Facebook Page often promises a neighborhood conversation.

If you can paste the same text everywhere, the text wasn’t written for anyone.

Example. You’re launching a coaching session. LinkedIn: “I’ve watched 40 founders push content to Sunday night. Here’s the slot we’re testing, and why it breaks less.” Instagram: workshop photo, first line “Sunday 6pm, we stop improvising the week.” TikTok: face to camera, “Stop. Your calendar isn’t punishment.” Same offer. Three contracts.

Plumbing, so you stay on substance

Encrypted tokens, publish at the right slot, retries if the API fails: the tool handles plumbing. You don’t need to remember whether Meta wants a 4:5 ratio or LinkedIn truncates the link. When a publish fails, the status says so. You don’t learn three days later in a spreadsheet.

• One source draft, not four Notes documents.
• One reread per network: 30 seconds, not a rewrite.
• Linked accounts, not passwords emailed to yourself.
• A visible queue: what goes Monday, what’s waiting, what failed.

Free or Pro: the real criterion

If you’re still hesitating between Free and Pro, don’t compare pricing pages like catalogs. Look at linked accounts and daily assisted writing actions. Those are the real ceilings. Scheduling is already unlimited. You don’t pay for “permission to publish on Thursday.” You pay when assisted writing and accounts become the bottleneck.

A freelancer with Instagram + LinkedIn often stays on Free the first month. A small agency managing three clients doesn’t. The switch isn’t a status. It’s a counter.

Each network’s rules, and how scheduling works, are in the docs.
