Pricing side by side
ContentIn has two self-serve plans and a custom one:
- Growth: $39 a month, or $31 a month billed yearly.
- Pro: $59 a month, or $48 a month billed yearly.
- Agency: custom pricing.
It offers a 7-day trial.
Coflux Pro is $59 a month. There's no yearly discount right now, so ContentIn Pro is cheaper if you pay for a year up front. Coflux Free costs nothing and has no time limit, which makes it easier to test properly before you commit.
How to decide between two similar tools
Give both the same idea. Pick a real topic, like a customer story from last month, and ask each tool for a post. Keep the one whose draft needs fewer edits to sound like you.
You want visuals made for you. If AI carousels and images matter now, ContentIn has them. Coflux graphics are coming soon.
You want to borrow structure from posts that worked. Coflux's inspiration library lets you pick a high-performing post and write your own version, in your voice.
What ContentIn does well
ContentIn has a few extras around the post: AI carousels, automatic first comments, lead analytics that show whether the people engaging match your ideal customer, a Telegram bot, and an agency plan with approvals. It also has a lot of public reviews.
What Coflux does well
Drafts get checked before you see them. Coflux works in steps. It plans the angle and the hook, writes the post, then reviews it. If the hook is weak, it rewrites it. You get fewer drafts that start with a bland line.
Inspiration you can actually use. Browse high-performing LinkedIn posts, see why each one works, and click "Write mine like this." You get the structure, about your topic, in your voice. A copy check blocks drafts that reuse too much of the original.
Set up in minutes. If you've used ChatGPT or Claude for a while, they already know a lot about you. Paste that in and Coflux fills your Identity profile.
Try everything for free. No trial clock. The free plan has every feature with daily limits.
Choose ContentIn if...
You want AI-made carousels and images today, you care about lead analytics that score who engages, or you write for clients and need an agency plan. Its $39 Growth plan is also a cheaper way in.
Switching
