How many “watch later” YouTube videos do you have saved? What about that folder of podcast episodes you swore you’d listen to, or the chaotic mess of notes from last week’s all-hands meeting? If you’re anything like me, you’ve got a digital content graveyard, and it’s getting crowded. We save things with the best intentions, but finding the time to actually process it all? That's a different story.
It’s a modern problem. We're drowning in information but starved for actual knowledge. So when a tool like Sintesy pops up on my radar, claiming to “transform voice into structured knowledge,” my inner productivity nerd gets… excited. A little tingly, even. An AI that transcribes, summarizes, and organizes all that audio and video content for me? Sign me up.
But as we know in the world of SEO and digital marketing, a slick landing page doesn't always equal a great product. So, I decided to take it for a spin. No marketing fluff, just my real-world experience. Is this the “second brain” we’ve all been waiting for, or just another shiny object?
So, What Is Sintesy, Anyway?
At its core, Sintesy is an AI-powered app designed to listen for you. Think of it less like a cold, calculating robot and more like a hyper-efficient personal assistant. You can throw an audio file, a video recording, or even a YouTube link at it, and it gets to work. First, it transcribes the whole thing. Then, its AI brain sifts through that mountain of text to pull out the important stuff, creating neat, digestible summaries. The goal is to take you from “da bagunça até o insight” as they say on their site—from mess to insight. I love that.
It's built for anyone who has to absorb information from spoken sources. Students recording lectures, professionals in back-to-back Zoom calls, content creators researching topics… the list goes on. Instead of scrubbing through a one-hour video to find that one golden nugget of information, Sintesy aims to just hand it to you.

The Features That Actually Matter
A tool can have a million features, but usually, only a few really move the needle. Here’s what stood out to me during my test drive.
The Magic of Transcription (and Its Limits)
The automatic transcription is, frankly, the foundation of everything here. I uploaded a recording of a recent client call (with permission, of course) and it churned out a full transcript in minutes. The accuracy was pretty darn good. It managed to pick up on most of the industry jargon we were throwing around.
But—and this is a big but—no AI transcription is perfect. I tried another recording, this one from a brainstorming session in a noisy coffee shop. The results were… more creative. Sintesy’s noise filtering definitely helped, but it struggled with the background chatter and cross-talk. It’s a good reminder that the old rule still applies: garbage in, garbage out. For the best results, you need clear audio. It’s not magic, its technology.
From Transcript to Insight: The AI Summaries
This is where things get really interesting. Getting a wall of text from a transcript is one thing; getting a useful summary is another. And Sintesy does a surprisingly good job. It doesn't just pull out random sentences. It seems to grasp the main topics, organize them into sections, and even identifies key terms and dates. For my client call, it correctly identified the main action items and follow-up questions. That alone is a huge timesaver.
The Pro plans mention “advanced summaries,” which I take to mean a more contextual and structured output. For anyone dealing with dense, technical content, this is probably the main reason to upgrade.
Taming the YouTube Rabbit Hole
Okay, this feature is a game-changer for me. As an SEO, I watch a ton of content from folks like Ahrefs or Matt Diggity—webinars, conference talks, case studies. Being able to just drop a YouTube link into Sintesy and get a full transcript and a summary feels like cheating. In a good way. It lets me absorb the key points of a 45-minute presentation in about five minutes. I can quickly decide if the full video is worth my time, or just pull the stats I need and move on. Productivity unlocked.
Let's Talk Money: Sintesy Pricing Explained
Alright, the all-important question: what’s this going to cost? Sintesy's pricing is pretty straightforward, and it's listed in Brazilian Real (R$), so keep that in mind when you're doing the conversion.
They have three main tiers:
- Plano Free: This is your entry point. It's free forever, which is great, but it's more of a taster. You get limited transcriptions and you miss out on the best features like YouTube summaries, PDF/DOCX exporting, and advanced summaries. It's enough to see if you like the feel of the tool, but you'll hit a wall pretty quickly if you use it seriously.
- Pro Mensal (Monthly): For R$39,90 per month, you get everything. Unlimited transcriptions, YouTube summaries, premium sharing, and all the bells and whistles. This is the plan for you if your workload fluctuates or you're not ready to commit for a full year.
- Pro Anual (Annual): This is the best value, hands down. It's R$29,90 per month (billed annually at R$358,80). You get all the same unlimited features as the monthly plan, but you end up saving a cool R$120 over the year. If you know you're going to be using this regularly for meetings and research, this is the smart move.
Both Pro plans come with a 7-day free trial, so you can test the full experience before your card gets charged. I always appreciate a company that lets you properly kick the tires.
The Good, The Bad, and The... AI-ish
No review is complete without a little reality check. So here’s my breakdown of what I genuinely liked, and where I think there's room for improvement.
What I Genuinely Liked
The time-saving aspect is undeniable. It's not just about getting a transcript; it’s about the mental energy you save. Not having to furiously type notes during a meeting allows you to be more present and engaged. I also love how it organizes information. My brain is a chaotic place, and having a tool that automatically creates structured notes from a rambling conversation is just fantastic.
Where It Could Be Better
As mentioned, the transcription accuracy is heavily dependent on your audio quality. That's not really Sintesy's fault, but it's a limitation to be aware of. The free plan also feels a bit restrictive. I get why they do it, but not having YouTube summaries on the free plan means you can't test one of its most powerful features. I also found myself wishing for more integrations beyond just the main video conferencing platforms, but maybe that's on their roadmap.
Who Is Sintesy Actually For?
I can see a few people getting massive value out of this.
The Overwhelmed Student: Recording lectures and getting instant, summarized notes? This would have been an absolute dream back in college. A total academic weapon.
The Busy Professional: If your calendar looks like a game of Tetris with back-to-back meetings, this is for you. It's a way to keep a perfect record without losing your mind.
The Content Creator & SEO: For research, this is just gold. Sifting through interviews, webinars, and competitor videos becomes incredibly efficient. It's a tool for turning raw information into actionable content ideas.
My Final Take: Is Sintesy My New Second Brain?
After spending some quality time with Sintesy, I'm genuinely impressed. It’s not perfect, but it’s very, very good at what it does. It effectively tackles the problem of information overload and helps close the gap between passively consuming content and actively learning from it. It brings you back from that content graveyard I mentioned earlier.
It won't do the thinking for you. But it does an amazing job of clearing away the administrative clutter—the note-taking, the transcribing, the organizing—so you have more time and brain space to think. And in our line of work, that’s just about the most valuable thing there is.
