    Best quote from Chemical Attraction: The Science of Social Scent & Chemosignals

    “

    While we like to think of ourselves as creatures of logic, we are deeply influenced by social chemosignals—invisible chemical messages that act as a secret language between our bodies. This 'gut feeling' you have about someone might actually be a 'nose feeling' instead.

    Frequently Asked Questions

    Social chemosignals are invisible chemical messages that act as a secret language between human bodies. Processed below the level of conscious awareness, these signals function as a high-speed, subconscious communication system refined over millions of years of evolution. They allow our bodies to exchange a wealth of information instantly, influencing our heart rates and creating an inexplicable pull toward others even before a single word is spoken.

    Chemical attraction is often what we describe as a 'spark' or 'chemistry' when meeting someone new. According to modern neuroscience, these chemical signatures provide critical data regarding genetic compatibility and a person's current emotional state. While we often believe we are guided by logic or visual preference, our social lives are deeply influenced by these foundational signals that help determine instant liking or intense curiosity.

    Although humans have historically been dismissed as 'microsmatic'—meaning we have a poor sense of smell compared to dogs—modern neuroscience reveals a different story. Humans are actually incredibly sensitive to the specific chemical signatures of our own species. Our noses do significant heavy lifting in our social interactions, processing complex chemosignals that serve as a primary, though often ignored, tool for navigating social environments and human connections.

    Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!

    @ladyInfinity

    I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.

    @jayallen

    The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.

    @Raguipa

    What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.

    @colonyofcreatorsNGO

    I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.

    @BeFreed user

    It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.

    @austinakon

    I love this app. Used it for several days and I cannot stop listening. Such a great way to start.

    @jcrules328

    I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.

    @DanielCZ

    I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.

    @BeFreed user

    I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.

    @Brad

    I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!

    @BeFreed user

    The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.

    @jayallen

    BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.

    @BeFreed user

    At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!

    @matteo77

    BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
