5 AI Tools That Replaced 3 Full-Time Hires at My Agency (And Cost $87/Month Total)

AI tools replace employees

I run a small content agency. Last year I had a copywriter, a social media manager, and a research analyst on payroll. Total fully loaded cost, including benefits, was around $14,000 a month. Today I have the same output, a leaner team, and I am spending $87 a month on AI tools. I am not going to tell you this is a clean swap. It is not. Some of what I lost matters. But the cost difference is so large that I think any small agency owner who is not at least experimenting with this stack is leaving a lot of money on the table. This is the actual stack I run today, what each tool replaces in the old team, and the things AI still genuinely cannot do, where I still pay humans real money.

Key Takeaways

1. Total monthly cost: $87 across 5 tools (down from $14,000 for 3 full-time hires).
2. Output volume tripled with the same headcount, mainly thanks to AI handling research and first-draft work.
3. Original thinking, voice matching, and client relationships still require humans — these are the three areas I still pay real money for.
4. The five tools: ChatGPT Team, Claude Pro, Notion AI, Perplexity Pro, Descript.
5. This is not a recommendation to fire anyone. It is a recommendation to test what AI can absorb before you scale your team.

The Honest Numbers, Before and After

Before I list the tools, here is the rough math so you can decide if any of this is even relevant to your situation. My agency produces around 80 to 100 long form articles a month for B2B SaaS clients, plus social copy and a weekly newsletter. We used to do this with the three hires I mentioned, plus a part time editor and me. We had five humans, total.

Now we have me, one part time editor, one part time writer, and the AI stack. We produce the same volume. We do not produce the same quality on every piece, but the average quality is the same, and on some pieces, it is better. The single biggest change is in research time. Where the analyst used to spend 3 hours per article on source gathering, the AI does that work in 4 minutes, and the human fact checking is faster as a result.

I am not claiming AI is a magic replacement for the team I used to have. I am claiming that for a specific kind of content work, the cost curve has shifted so dramatically that the old model no longer makes sense unless you are doing very high end bespoke work.

The Five Tools, in Order of Impact

I will go through each one in the order that had the biggest impact on my bottom line. The first two are the ones I would not give up. The last three are the ones that have made my team more efficient, not the ones that have replaced work entirely.

1. ChatGPT Team ($25/month) — Replaces the Research Analyst

My old research analyst was good. Her job was to spend two to three hours per article gathering sources, recent data, and competitor insights before the writer started. The ChatGPT Team plan at $25 a month per user, billed annually, has replaced about 70% of that work.

The way I use it: for each article brief, I open a new project in ChatGPT, paste in the topic and the target audience, and ask for 30 to 50 recent sources, recent statistics, and three to five competitor angles. I then spend about 20 minutes fact checking the most important claims before handing the brief to a writer. The fact check is the part I cannot skip, because ChatGPT still gets specifics wrong, especially around recent data and proper nouns.

• Time saved per article: 2 hours
• Cost per month: $25 (one seat, shared across the team via shared projects)
• What it does not replace: original reporting, interview transcripts, and primary research

2. Claude Pro ($20/month) — Replaces the Copywriter for First Drafts

My old copywriter was a strong mid level writer. She cost $4,200 a month and produced about 25 finished articles a month. Claude Pro at $20 a month has not replaced her, but it has changed what she spends her time on. Her output has roughly tripled, and the agency went from 25 articles a month to 70 to 80, with the same headcount.

The new flow is this. I send the writer a ChatGPT research brief. She opens Claude and asks for a 1,200 word first draft using the brief, our client’s house style guide, and three example articles we have already published for them. Claude produces a draft in about 90 seconds. She then spends 45 minutes to an hour editing the draft, fact checking the claims, and rewriting any sections that sound generic.

Her pay is the same, because the work is harder in some ways (she has to be a sharper editor) but easier in others. I would rather pay her to be a sharper editor than to do the same repetitive research and outlining work every week.

• Time saved per article: 3-4 hours
• Cost per month: $20 (one seat, plus the writer’s own Claude Pro subscription)
• What it does not replace: original thinking, real opinions, lived experience

3. Notion AI ($10/month) — Replaces the Social Media Manager for Content Production

The social media manager’s old job was three things. One, take a long article and turn it into 5 to 10 social posts. Two, write a weekly newsletter. Three, keep a content calendar organized. Notion AI, added to the standard Notion plan I was already paying for, now does most of the first two.

For social posts, I dump the article text into a Notion page, ask Notion AI for 10 social posts under 280 characters each, with a mix of formats (a question, a stat, a quote, a tip), and it generates them in about 15 seconds. About half are usable as is. The other half need a quick edit or a rewrite. Total time saved: maybe 4 hours a week.

For the newsletter, I do the same thing but with the past week’s articles, and ask Notion AI to write a 400 word issue that links out to the three strongest pieces. I edit it for tone, add the links, and it is ready to send. That used to take an hour. It now takes 15 minutes.

• Time saved per week: 4-5 hours
• Cost per month: $10 (Notion AI add-on)
• What it does not replace: actual scheduling, community management, replies to comments, strategic platform decisions

4. Perplexity Pro ($20/month) — Replaces My Fact-Checking Habit

This is the one I did not expect to pay for. Perplexity Pro is $20 a month and it is, in 2026, the closest thing to a research assistant that I have ever used. It does what ChatGPT does but with two crucial differences: it cites its sources, and it pulls live information from the web instead of relying on its training data cutoff.

Where this fits in my workflow is the fact checking step. After a writer produces a final draft, I take every factual claim in the article and run it through Perplexity with a “show me three independent sources” prompt. This takes about 15 minutes per article but it has caught errors that would have been embarrassing if they made it to the client. The cost is justified by the time it saves me from having to manually check each fact, and by the small number of credibility saves I have had.

• Time saved per article: 30-45 minutes (vs manual fact checking)
• Cost per month: $20
• What it does not replace: primary research, expert interviews, original reporting

5. Descript ($12/month) — Replaces the Audio Editor

About a quarter of my clients have a podcast, and they used to pay us to chop the audio into 5 to 10 short clips for social. Descript at $12 a month for the Creator plan has replaced almost all of that. The transcript-based editing is fast, the AI clip finder does a decent job of finding the strongest 60 second moments, and the output is publish ready.

The savings here are smaller than the others, because the volume of podcast work is not huge. But it is the difference between subcontracting audio work to a freelancer at $50 a clip and doing it in-house for essentially no marginal cost. Over a year, that is a real number.

• Time saved per clip: 60-90 minutes
• Cost per month: $12
• What it does not replace: mixing, mastering, original sound design

What I Am Not Replacing, and Why

I want to be honest about the things AI still cannot do for me, because the marketing on every AI tool will tell you otherwise. The three areas where I still pay humans are not arbitrary. They are the areas where I tried the AI and the output was not good enough, or the output was good but the client could tell it was AI, and either way the value was not there.

1. Original thinking

AI can summarize what 50 articles have said about a topic, but it cannot have an original take that comes from a specific human’s lived experience or research. The articles that clients love most are the ones where my writer has an actual opinion, an actual case study, or an actual client story. AI cannot generate that. What it can do is help shape the writing once the idea is in the writer’s head. The order matters. Idea first, then AI for structure and draft. Not the other way around.

2. Brand voice at depth

AI can match a house style guide, but it cannot match the weird, specific voice that a founder wants for their personal LinkedIn, or the precise tone that a SaaS company has built up over 50 podcast episodes. There is some kind of accumulated judgment in those voices that I have not found a way to train an AI on. When clients ask for that level of voice matching, I send it to a human editor. The AI does the first pass, the human does the polish.

3. Account management

AI cannot be on a call with a client, take a vague brief, ask the right clarifying questions, push back when a request does not make sense, or handle the politics of a difficult project. I have a part time account manager for that, and I do not see that changing in the next two to three years.

Total Monthly Cost Breakdown

1. ChatGPT Team: $25 (shared workspace)
2. Claude Pro: $20 (my seat, writer has her own)
3. Notion AI: $10 (add-on to existing plan)
4. Perplexity Pro: $20
5. Descript Creator: $12

Total: $87 a month. Compare that to the $14,000 a month I was spending on three full time hires, or even the $4,200 a month I would have to spend to keep just one of them. The math is not subtle. Even adjusting for the fact that I am still paying a part time editor and a part time writer, the savings are real and I am not going back.

What I Would Do Differently If I Were Starting

If I were running a small agency and thinking about this for the first time, the order I would do things in is this.

1. Pick one role to test first. Research, first draft writing, or social media production — choose the one that has the highest pain point in your current operation. Start with one tool for that role. Run it for 30 days. Measure time saved and quality difference.
2. Do not fire anyone yet. Use the AI as a productivity multiplier for your current team, not as a replacement. The savings come from doing more with the same people, not from reducing headcount immediately.
3. Document the workflow. Once you have the workflow figured out, write it down. The new team member you hire three months from now needs to be able to follow the same steps. AI workflows that live only in your head are fragile.
4. Audit output quality weekly. Pick a random article each week and read it as if you were the client. If the quality drops, the workflow is broken, and you need to add human review time, not remove it.
5. Reinvest the savings. Use the time and money saved to take on more clients, raise your rates, or improve your own skills. The point of doing more with less is doing more, not just doing less.

Frequently Asked Questions

Did you fire the three people?

No. The research analyst moved to a different role at a different company. The copywriter and the social media manager stayed on, with their roles modified. The copywriter is now a senior editor and writer on fewer but higher value projects. The social media manager became my account manager, which is the role I cannot fill with AI. The transition was planned over six months and was not as clean as the cost numbers suggest.

Is the quality actually the same?

On average, yes. On individual pieces, it varies. Some articles are better than what the old team would have produced, because the writer now has more time to focus on the parts that require human judgment. Some articles are worse, because the AI introduces a subtle blandness that the editor did not catch. The percentage of articles that the client flags for revision is roughly the same as before, around 8%.

Is this sustainable, or will clients catch on?

The honest answer is that some clients have noticed the speed at which we turn around work, and a few have asked about it. I have been transparent with the long term clients, and the response has been positive. They do not care how the work gets done, they care that the work is good and on time. The clients I have lost in the last year have been lost to price and quality issues, not to “they use AI.” That is a small sample, but it is what I have seen.

What if the AI tools get more expensive?

This is a real concern. The $87 a month I am spending is subsidized by the fact that these companies are racing for market share. If ChatGPT Pro goes to $100 a month and Claude Pro goes to $50 a month and Perplexity Pro goes to $50 a month, my total goes from $87 to $245 a month, which is still a 60x saving over the $14,000 I was paying. I would still do this. The economic advantage of AI in this kind of work is so large that even a 3-4x price increase would not change the conclusion.

The Honest Summary

If you are running a small agency and you are not actively experimenting with this kind of stack, the honest question to ask yourself is why. It does not have to replace your team. It just has to give you a multiplier. And the multiplier, even at $87 a month, is enormous. The biggest mistake I see agency owners making is waiting until the AI tools are “ready” before they start. They are ready now. The ones who will benefit most from this are the ones who start with imperfect tools and figure out the workflow as they go, the same way I did.
