Most "free" LinkedIn comment generators aren't actually free. They offer limited trials, require credit cards upfront, or restrict you to 2-3 comments before demanding payment.

This guide examines five genuinely free LinkedIn comment generator options—tools you can use today without spending a dollar.

## What "Free" Actually Means

**Truly free tools provide:**
- No credit card required to start
- Functional free tier (not just a trial)
- Useful limits (not 1-2 test comments)

**"Free trial" is not the same as "free":**
- LigoAI offers 30 free comments (trial, then paid)
- Engage AI offers limited free tier
- Most tools are freemium, not free

This article focuses on tools you can use indefinitely without payment.

---

## 4. Claude (Anthropic) - ChatGPT Alternative

**Pricing:** Free forever

**How it works:**
Same as ChatGPT but with Claude AI.

**Prompt:**
```
Generate a professional LinkedIn comment (50 words) for this post. Be specific and conversational:

[paste post]
```

**Why consider Claude:**
- Some users prefer Claude's tone
- Completely free
- Unlimited generations
- Different AI personality than ChatGPT

**Limitations:**
- Same manual workflow as ChatGPT
- No integration
- Copy-paste required

**Best for:** Users who want ChatGPT-quality AI with a different "voice."

---

## 5. LinkedIn Native + Manual - The Purist Approach

**Pricing:** $0 (your time only)

**The method:**
1. Read post carefully
2. Think about valuable insight
3. Write comment manually
4. Edit for clarity
5. Post

**Why this matters:**
- 100% authentic
- No AI detection concerns
- Builds real skills
- Zero cost

**When this makes sense:**
- Commenting on high-value posts
- Building key relationships
- Sensitive topics
- Showcasing expertise

**Limitations:**
- Time-consuming (2-3 minutes per comment)
- Not scalable
- Consistency challenges

**Best for:** Purists who prioritize 100% authenticity over efficiency.

---

## Free vs Paid: Is Upgrading Worth It?

**What free tools can't do:**
- Voice learning (AI doesn't remember your style)
- LinkedIn integration (no browser extensions)
- Unlimited quality (ChatGPT free = GPT-3.5, paid = GPT-4)
- Analytics (no performance tracking)

**When free tools work:**
- Low volume (5-10 comments daily)
- Manual workflow acceptable
- Budget is primary concern
- Testing AI commenting

**When paid tools make sense:**
- High volume (15+ comments daily)
- Integrated workflow needed
- Voice consistency matters
- Time is more valuable than money

## Comparison Table

| Tool | Truly Free? | Monthly Limit | AI Quality | Integration | Best For |
|------|-------------|---------------|------------|-------------|----------|
| **ChatGPT** | ✅ Yes | Unlimited | Good | ❌ | Budget users |
| **LigoAI** | 30 comments | One-time | Excellent | ✅ | Testing premium |
| **Copy.ai** | ✅ Yes | 2,000 words | Good | ❌ | Multi-use |
| **Claude** | ✅ Yes | Unlimited | Good | ❌ | ChatGPT alternative |
| **Manual** | ✅ Yes | Unlimited | Perfect | N/A | Purists |

---

## How to Maximize Free Tools

**Strategy 1: ChatGPT for Most, Manual for VIPs**
- Use ChatGPT for 80% of comments
- Go fully manual for top 20% (key relationships)
- Saves time while preserving authenticity where it matters

**Strategy 2: Use LigoAI Trial Strategically**
- Save 30 free comments for important posts
- Use ChatGPT for practice/low-stakes comments
- Upgrade to paid if trial proves value

**Strategy 3: Combine Free Tools**
- ChatGPT for comment drafts
- Copy.ai for post ideas
- Manual editing for all outputs
- $0/month total cost

---

## Free Tool Limitations (Honest Assessment)

**Why free tools have drawbacks:**
- No integration = workflow friction
- No voice learning = generic outputs
- Manual processes = time investment
- Limited support = you're on your own

**The reality:**
Free tools work for light users (5-10 comments daily). Heavy users (15-20+) eventually upgrade because time savings justify cost.

**ROI calculation:**
- Manual commenting: 2.5 min/comment × 15 daily = 37.5 min
- ChatGPT: 1 min/comment × 15 daily = 15 min (saves 22.5 min)
- LigoAI (paid): 0.5 min/comment × 15 daily = 7.5 min (saves 30 min)

If your time is worth $50/hour:
- ChatGPT saves: $18.75/day = $375/month
- LigoAI saves: $25/day = $500/month

Even at $30-40/month, paid tools deliver 10-15x ROI for high-volume users.

---

## Start With Free, Upgrade When Ready

**Recommended path:**

**Week 1-2: ChatGPT (Free)**
- Learn AI commenting
- Test different prompts
- Build commenting habit

**Week 3: LigoAI Trial (30 Free Comments)**
- Experience integrated workflow
- Compare AI quality
- Evaluate voice learning

**Week 4: Decision Point**
- Stick with free if volume is low
- Upgrade if time savings justify cost
- Mix free + paid strategically

Most users discover:
- ChatGPT works for 5-10 comments daily
- Paid tools worth it at 15+ daily
- Hybrid approach (free + paid) is smartest

---

## Final Verdict

**Best free option:** ChatGPT (unlimited, high quality, $0 forever)

**Best "test premium" option:** LigoAI (30 free comments to try GPT-4-class AI)

**Best multi-use free tool:** Copy.ai (2,000 words for all content types)

Start with ChatGPT. If you love AI commenting and your volume increases, test LigoAI's trial. Upgrade only when ROI is clear.

Free tools are powerful. Use them strategically.

## Frequently Asked Questions (FAQ)

### Is there a completely free LinkedIn comment generator?

Yes, ChatGPT (free version) is completely free forever with unlimited comment generation. Other truly free options include Claude (Anthropic's AI) and manual commenting. LigoAI offers 30 free comments as a trial (not indefinitely free), and Copy.ai provides 2,000 free words monthly (~80-100 comments). ChatGPT free is the best unlimited option, though it requires manual copy-paste workflow.

### What's the difference between free and paid LinkedIn comment tools?

Free tools lack voice learning (AI doesn't remember your style), require manual copy-paste workflows, don't integrate with LinkedIn directly, and typically use older AI models (GPT-3.5 vs GPT-4). Paid tools offer LinkedIn browser extension integration, AI that learns your commenting voice over time, better AI quality, analytics, and time-saving automation features. Free works for 5-10 comments daily; paid makes sense at 15+ comments daily.

### How many free comments does LigoAI offer?

LigoAI offers 30 free comments as a trial to test the AI quality and see how well it adapts to your commenting style. After the 30-comment trial, you need a paid plan to continue using the tool. The free trial includes full access to GPT-4-class AI, voice learning features, and works across LinkedIn, Twitter, Reddit, and Facebook.

### Can I use ChatGPT for free to generate LinkedIn comments?

Yes, ChatGPT's free version (GPT-3.5) offers unlimited comment generation. The workflow: copy LinkedIn post text, paste into ChatGPT with a detailed prompt, review the AI-generated comment, customize it for your voice, and manually post on LinkedIn. While the workflow is manual, the AI assistance is completely free forever with no usage limits or credit card required.

### Is Copy.ai good for LinkedIn comments?

Copy.ai's free plan (2,000 words/month) can generate approximately 80-100 LinkedIn comments. It has a dedicated "LinkedIn Comment" template and is decent for testing AI comments. However, the 2,000-word limit runs out quickly if you use Copy.ai for other content types (emails, blog posts, ads). Best for marketers who need AI for multiple purposes, not just LinkedIn comments. No LinkedIn integration means manual copy-paste workflow.

### Do free LinkedIn comment tools work as well as paid ones?

Free tools deliver similar comment quality but require more time and effort. ChatGPT's free version produces good comments but needs manual copy-paste and doesn't learn your voice. Paid tools like LigoAI save 20-30 minutes daily through browser integration and voice learning, delivering similar output quality but with significantly better workflow efficiency. If you comment 15+ times daily, paid tools deliver 10-15x ROI through time savings alone.

### How long does it take to generate comments with free tools?

Manual commenting takes ~2.5 minutes per comment. ChatGPT (free) reduces this to ~1 minute per comment (copy post, paste into ChatGPT, copy response, customize, post on LinkedIn). LigoAI (paid) reduces it to ~30 seconds per comment with one-click generation directly in LinkedIn. For 15 daily comments, that's 37.5 minutes manually, 15 minutes with ChatGPT, or 7.5 minutes with paid tools.

### Are there any risks to using free AI comment generators?

The main risks are posting obvious AI-generated content without customization (makes you look spammy) and spending too much time on manual workflows. LinkedIn doesn't ban you for using AI writing assistance—the risk comes from fully automated posting without human review. Free tools like ChatGPT require manual posting, so ban risk is zero. Always customize AI outputs before posting to maintain authenticity.

### What's the best free option for beginners?

ChatGPT (free version) is the best option for beginners. It's unlimited, user-friendly, produces decent comment quality, and helps you learn what good AI comments look like. Start with ChatGPT for 1-2 weeks, then test LigoAI's 30 free comments to experience premium AI and integrated workflow. This progression helps you decide if paid tools are worth it based on your commenting volume and time value.

### Can I combine multiple free tools to avoid paying?

Yes, combining free tools is an effective strategy. Use ChatGPT for most comments (unlimited), save LigoAI's 30 free trial comments for important high-value posts, use Copy.ai's 2,000 words for other content needs, and go fully manual for VIP relationship building. This hybrid approach costs $0/month while optimizing each tool for what it does best. Most users following this strategy eventually upgrade to paid when volume increases beyond 15-20 comments daily.

The free trial includes full access to GPT-4-class AI, voice learning features, and works across LinkedIn, Twitter, Reddit, and Facebook.</p>
<h3>Can I use ChatGPT for free to generate LinkedIn comments?</h3>

The workflow: copy LinkedIn post text, paste into ChatGPT with a detailed prompt, review the AI-generated comment, customize it for your voice, and manually post on LinkedIn. While the workflow is manual, the AI assistance is completely free forever with no usage limits or credit card required.</p>
<h3>Is <a href="http://Copy.ai">Copy.ai</a> good for LinkedIn comments?</h3>
<p><a href="http://Copy.ai">Copy.ai</a>’s free plan (2,000 words/month) can generate approximately 80-100 LinkedIn comments. It has a dedicated “LinkedIn Comment” template and is decent for testing AI comments. However, the 2,000-word limit runs out quickly if you use <a href="http://Copy.ai">Copy.ai</a> for other content types (emails, blog posts, ads). Best for marketers who need AI for multiple purposes, not just LinkedIn comments. No LinkedIn integration means manual copy-paste workflow.</p>
<h3>Do free LinkedIn comment tools work as well as paid ones?</h3>
<p>Free tools deliver similar comment quality but require more time and effort. ChatGPT’s free version produces good comments but needs manual copy-paste and doesn’t learn your voice.

If you comment 15+ times daily, paid tools deliver 10-15x ROI through time savings alone.</p>
<h3>How long does it take to generate comments with free tools?</h3>
<p>Manual commenting takes ~2.5 minutes per comment. ChatGPT (free) reduces this to ~1 minute per comment (copy post, paste into ChatGPT, copy response, customize, post on LinkedIn). LigoAI (paid) reduces it to ~30 seconds per comment with one-click generation directly in LinkedIn. For 15 daily comments, that’s 37.5 minutes manually, 15 minutes with ChatGPT, or 7.5 minutes with paid tools.</p>
<h3>Are there any risks to using free AI comment generators?</h3>
<p>The main risks are posting obvious AI-generated content without customization (makes you look spammy) and spending too much time on manual workflows. LinkedIn doesn’t ban you for using AI writing assistance—the risk comes from fully automated posting without human review. Free tools like ChatGPT require manual posting, so ban risk is zero. Always customize AI outputs before posting to maintain authenticity.</p>
<h3>What’s the best free option for beginners?</h3>
<p>ChatGPT (free version) is the best option for beginners. It’s unlimited, user-friendly, produces decent comment quality, and helps you learn what good AI comments look like. Start with ChatGPT for 1-2 weeks, then test LigoAI’s 30 free comments to experience premium AI and integrated workflow. This progression helps you decide if paid tools are worth it based on your commenting volume and time value.</p>
<h3>Can I combine multiple free tools to avoid paying?</h3>
<p>Yes, combining free tools is an effective strategy. Use ChatGPT for most comments (unlimited), save LigoAI’s 30 free trial comments for important high-value posts, use <a href="http://Copy.ai">Copy.ai</a>’s 2,000 words for other content needs, and go fully manual for VIP relationship building. This hybrid approach costs $0/month while optimizing each tool for what it does best. Most users following this strategy eventually upgrade to paid when volume increases beyond 15-20 comments daily.</p>
