Free LinkedIn Post Generators — Top 7 Tools Compared

What to expect from free LinkedIn post generators

Free tools almost always limit you in one of three ways: usage caps (a set number of generations per month), feature caps (no brand voice training, no scheduling), or quality caps (generic output that needs heavy editing). Knowing which cap matters most for your use case helps you pick the right tool.

1. Roosbot (7-day free trial)

Roosbot's free trial gives you full access to all paid features for 7 days — including LinkedIn-specific generation with brand voice training, multi-platform support, and approval workflows. It's not a permanent free plan, but the trial is the most complete LinkedIn content experience of any tool on this list.

Free limit: 7-day trial
Brand voice: Yes
Best for: Agencies and teams who want to test a real workflow

2. Buffer AI (free plan)

Buffer's free plan includes basic AI caption generation. For LinkedIn specifically, you enter a prompt and get a post draft. No brand voice, no memory across sessions. The free plan limits you to three social channels and doesn't include advanced AI features.

Free limit: 3 channels, basic AI
Brand voice: No
Best for: Solo users posting occasionally

3. Copy.ai (free plan)

Copy.ai has a free tier with a limited number of AI generations per month. It has a LinkedIn post template that produces decent drafts from a short topic prompt. Output is generic without a brand context, but it's a quick way to get a starting point.

Free limit: 2,000 words/month
Brand voice: Paid only
Best for: Writers who want a starting point

4. Taplio (free features)

Taplio is built specifically for LinkedIn creators. It has AI post generation, post scheduling, and performance analytics — but most features are behind a paid plan. The free tier is heavily restricted. Worth trying if you're serious about LinkedIn growth.

Free limit: Very restricted
Brand voice: Paid only
Best for: LinkedIn-focused personal brand builders

5. Notion AI (free credits)

Notion AI gives you a small number of free AI generations when you first sign up. You can use it to write LinkedIn posts inside a Notion doc. It's not a dedicated LinkedIn tool, but the writing quality is good. No scheduling or publishing.

Free limit: Limited credits then $10/month
Brand voice: Partial (via prompting)
Best for: Notion users who already live in that environment

6. ChatGPT (free plan)

ChatGPT's free plan uses GPT-4o mini. You can ask it to write LinkedIn posts and it does a reasonable job. No memory across conversations by default on the free plan, no scheduling, no publishing. It's a blank writing assistant, not a LinkedIn tool.

Free limit: Usage caps apply during peak hours
Brand voice: Manual prompting only
Best for: Anyone who wants free AI writing without a dedicated tool

7. Writesonic (free trial)

Writesonic has a free trial with limited word credits. It includes a LinkedIn post template. The output is average — it needs significant editing to feel authentic. The trial is short enough that you'll quickly hit the limit.

Free limit: 10,000 words/month on free plan
Brand voice: Paid only
Best for: One-time testing

What free actually gets you

If you need a few LinkedIn posts occasionally and don't mind editing heavily, most free tools will work. If you want consistent, on-brand output at volume — especially for clients — a free plan won't cut it. Use the free trials to properly evaluate the paid tools before committing.
