I am going to save you the months of testing we went through. We have tried probably 40-50 AI tools over the past two years. Most of them got used for a week, maybe two, and then abandoned. Either they did not actually save time, the output quality was not good enough to use without spending more time fixing it than just doing it manually, or they solved a problem we did not really have.
These eight survived. They are in our daily workflow. We pay for most of them. And I am going to be honest about what each one is bad at, because every "best AI tools" list on the internet reads like sponsored content and I find that useless.
1. ChatGPT (OpenAI) — The Workhorse
What we use it for: First drafts of blog posts, brainstorming content angles, rewriting ad copy variations, summarizing long documents, and sometimes just rubber-ducking strategy ideas. It is our most-used AI tool by a wide margin.
Real workflow: When we write a blog post for a client, we start by feeding ChatGPT the topic, the target audience, and three to four key points we want to cover. It gives us a rough draft in about 30 seconds. We then spend 45-60 minutes rewriting, adding our voice, inserting real examples, and cutting the AI-isms. The whole process takes about 90 minutes instead of three to four hours from scratch.
Where it sucks: It is terrible at being specific. Ask it for advice on Instagram strategy and you get generic advice that applies to everyone and no one. It cannot replace actual experience with real accounts and real data. It also has a bad habit of being confidently wrong about numbers and statistics, so always fact-check anything data-related. And the writing style, if you do not heavily edit it, sounds like every other piece of AI-generated content on the internet. You know the tone. You can smell it.
Cost: Free tier is decent. Plus plan at around 20 euros per month is worth it if you use it daily.
2. Canva Magic Studio — Design Without a Designer
What we use it for: Social media graphics, quick presentations for clients, resizing content across platforms, background removal, and occasionally generating images from text prompts for mood boards.
Real workflow: For a restaurant client's weekly Instagram posts, we create one carousel template in Canva, then duplicate and swap content for each week. Magic Resize lets us instantly convert an Instagram post into a Facebook cover, a LinkedIn graphic, and a Story format. What used to take our designer 30 minutes per platform now takes about two minutes.
Where it sucks: The AI image generation is mediocre. It is fine for abstract backgrounds or texture fills, but do not try to generate anything with people, text, or specific objects. You will get weird hands and misspelled words. Also, the "Magic Write" text generation inside Canva is much worse than ChatGPT. Use a dedicated writing tool and bring the text into Canva, not the other way around.
Cost: Pro plan at about 12 euros per month. Already using Canva? The AI features are baked into Pro.
3. Descript — Video Editing for People Who Hate Video Editing
What we use it for: Editing podcast episodes, cutting long videos into short clips for social media, transcribing client interviews, and creating audiograms.
Real workflow: A client records a 45-minute webinar. We drop it into Descript. It transcribes the whole thing in about two minutes. Then we literally highlight the best three to four minutes in the transcript, hit export, and we have short-form clips ready for Reels. We can remove filler words ("um," "uh," "you know") in one click. The text-based editing approach is genuinely brilliant. If you can edit a Word document, you can edit video in Descript.
Where it sucks: The auto-clip feature that is supposed to find the best moments? It is hit or miss. Maybe one out of four suggestions is actually good. You still need a human to identify what is actually interesting content versus what just sounds like a complete sentence. Also, the free plan is quite limited and the jump to paid feels steep if you are only editing occasionally.
Cost: Free plan for basics. Paid starts at around 20 euros per month.
4. Metricool — Social Media Scheduling That Actually Helps
What we use it for: Scheduling posts across all platforms, analyzing which content types perform best, tracking competitor accounts, and managing multiple client accounts from one dashboard.
Real workflow: Monday mornings we batch-schedule the entire week for every client. Metricool shows us optimal posting times based on each account's actual audience activity (not generic "best times to post" from some blog post). We review last week's analytics, note what worked, and adjust the upcoming week's content mix accordingly. The competitor tracking is quietly one of the most useful features: we monitor what competitors post, their engagement rates, and their posting frequency.
Where it sucks: The AI caption suggestions are... fine. Sometimes useful for a starting point, but they read very generic and you would never post them as-is. The analytics could be more granular. And the interface, while functional, is not exactly beautiful. It gets the job done without being a pleasure to use. Also, the free plan only covers one brand, which is useless for an agency.
Cost: Free for one brand. Paid plans start around 12 euros per month. Agency plans with multiple brands are pricier but worth it if you manage several accounts.
5. Opus Clip — Long Video to Short Clips on Autopilot
What we use it for: Turning webinars, long YouTube videos, and live stream recordings into vertical short-form clips for Reels, TikTok, and Shorts.
Real workflow: A client does a 30-minute live Q&A on Instagram. We download it, upload to Opus Clip, and it automatically identifies 10-15 potential clips, adds captions, and formats them vertically. Out of those, maybe 5-6 are actually usable. We tweak the captions, adjust the start and end points slightly, and have a week of short-form content from one live session. The time savings on this one are genuinely massive.
Where it sucks: It struggles with conversations between multiple people. If you have a podcast with two speakers, the clip selection gets confused about who is the main speaker and cuts at awkward moments. It also sometimes picks clips that are technically well-structured (good hook, complete thought) but are boring content that nobody would actually watch. The AI does not understand "interesting," just "structurally complete." You always need a human curator.
Cost: Limited free tier. Paid starts around 15 euros per month.
6. Tidio — AI Chatbot That Handles the Boring Questions
What we use it for: Answering common questions on client websites automatically, qualifying leads, booking appointments, and handling after-hours inquiries.
Real workflow: We set this up for a dental clinic in Barcelona. Trained the bot on their FAQ (about 40 common questions), pricing info, and booking procedures. Now when someone visits the site at 11pm and asks "do you accept my insurance?" or "what does a cleaning cost?", the bot answers immediately. Before Tidio, those people would leave and never come back. After implementation, the clinic saw a 28% increase in online appointment bookings, most of them coming outside business hours.
Where it sucks: It handles simple, factual questions well but completely falls apart on anything nuanced. If a patient describes a complex dental issue and asks for advice, the bot gives generic responses that feel robotic and unhelpful. You absolutely need to set up proper handoff to a human for anything beyond basic FAQs. Also, the setup is more time-consuming than they advertise. "Train your bot in 5 minutes" is marketing fantasy. Proper setup took us about three hours for that dental clinic.
Cost: Free plan available. AI features start around 20 euros per month.
7. Notion AI — Your Second Brain Gets Smarter
What we use it for: Summarizing meeting notes, generating project briefs from bullet points, creating SOPs, and searching across our entire knowledge base with natural language queries.
Real workflow: After every client call, we dump our rough notes into Notion. AI summarizes them into structured meeting notes with action items automatically extracted. We also use it to generate first drafts of project briefs: feed it bullet points about a project scope and it creates a structured brief we can refine. Our entire agency wiki is in Notion and being able to ask "what is our process for onboarding a new social media client?" and get a direct answer from our own documentation is incredibly useful.
Where it sucks: The AI writing quality is noticeably worse than ChatGPT. It is fine for internal documents but I would not use it for anything client-facing without heavy editing. It also sometimes "hallucinates" information when querying your database, pulling from its training data instead of your actual content. So you get an answer that sounds right but includes a step that is not actually in your SOP. Dangerous if you trust it blindly. Always verify against the source document.
Cost: AI add-on is about 8 euros per member per month on top of your Notion plan.
8. Brevo — Email Marketing with Smart Timing
What we use it for: Client email campaigns, automated welcome sequences, send-time optimization, and smart segmentation based on subscriber behavior.
Real workflow: We set up email automation for most of our clients through Brevo. The AI send-time optimization is the standout feature. Instead of guessing when to send, it learns when each individual subscriber is most likely to open. For a client newsletter, this alone improved open rates from 22% to 31%. We also use the behavior-based segmentation to automatically group subscribers who click on specific topics and send them more relevant follow-up content.
Where it sucks: The email template builder is clunky compared to Mailchimp. The drag-and-drop editor fights you on simple layout changes. Also, the AI subject line suggestions are consistently mediocre. They are grammatically fine but completely lack personality or hook. We never use them as-is. And the free plan caps you at 300 emails per day, which sounds generous until you have a list of 500 and want to send a campaign to everyone at once.
Cost: Free plan (300 emails/day). Paid starts around 22 euros per month for higher volume.
What We Learned After Two Years of Testing
The biggest mistake you can make is trying to adopt everything at once. We did this. We signed up for 12 tools in one month and used exactly two of them regularly. The rest were just subscriptions we forgot to cancel.
Here is what actually works: pick the one task that eats the most of your time. Find one AI tool that helps with that specific task. Use it for a month. Learn its quirks. Integrate it into your workflow properly. Then, and only then, add a second tool.
And always, always keep a human in the loop. Every tool on this list produces output that needs human review before it goes anywhere a client or customer will see it. AI tools are assistants, not replacements. The businesses that understand this distinction are the ones getting real value. The ones that treat AI as a magic "do my work" button are producing mediocre, generic content that their audience can smell from a mile away.
