딸각딸각!클릭만하면앱이뚝딱!코딩한줄없이완성하는나만의앱!Dify는복잡한LLM애플리케이션개발과정을시각적인워크플로로변환해누구나AI서비스를구축할수있도록돕는오픈소스플랫폼입니다.직관적인UI를통해코딩없이앱을만들수있어,누구나실제서비스를구현할수있는환경을제공합니다.이책은Dify의기초적인사용법부터시작해RAG(검색증강생성)를도입한고급챗봇,그리고SNS게시물,상품설명,기사요약등다양한글쓰기를자동생성하는텍스트생성기를만들어봅니다.더나아가,챗봇보다한단계더발전한AI에이전트를만들어보고복잡한대화제어및멀티모달기반의업무자동화워크플로까지구현해봅니다.특히구글스프레드시트,GoogleSearchAPI,DALL·E등외부툴과연동해‘영수증관리’나‘회의록작성’같은프로젝트를직접구축해볼수있도록구성했습니다.비개발자도막힘없이따라할수있도록풍부한도해와단계별그림을수록하여이론보다는실전중심의학습을돕습니다.이책과함께라면막연하게만느껴졌던생성형AI서비스생성부터배포까지의모든과정을자연스럽게익힐수있습니다.이제기술의한계를넘어,여러분의상상력을완벽하게작동하는AI앱으로바꾸는즐거움을경험해보세요.저자의말“프로그래밍같은건나한테는무리야.”예전부터이렇게생각해온분이많지않을까요?이책을쓴저역시한때는같은생각을품고있었습니다.학창시절‘앞으로는IT시대’라고느껴프로그래밍을배우려고학원에도다녔지만,영락없이내길이아니라는사실만절감한채좌절을맛본쓰라린경험이있습니다.그대로사회인이되어은행원으로커리어를시작했고,이후컨설팅분야와일반기업의신규사업론칭업무에종사하면서프로그래밍이나개발분야와는점점멀어졌습니다.독립후사업을펼쳐나가는과정에서도개발과는늘거리가있었습니다.코드를작성하고오류를수정하며무언가를작동시켜가는과정자체가인문계출신이자비즈니스분야에서일해온저와어딘가맞지않는듯느껴졌습니다.직접프로그램을만들수없으니기존도구를잘활용하고전문가에게시스템구축을의뢰하는수밖에없다며단념하고있었습니다.하지만2020년대중반에접어들면서AI의진화는우리일상과업무환경을크게바꾸기시작했습니다.지금빠르게확산되고있는생성형AI도구,그중에서도챗GPT로대표되는LLM(대규모언어모델)의등장은우리가‘개발’에지녀온고정관념을뿌리부터흔들고있습니다.지금까지는개발을코드작성능력이나전문지식을갖춘사람만다룰수있는영역으로여겼습니다.생성형AI가등장하면서이제는자연어,즉‘언어’로소통하는능력만있으면그영역에다가갈수있게되었습니다.저는이AI도구의발전에큰충격을받았습니다.2023년아이가태어나아버지로서새로운삶이시작되면서시간과노력을효율적으로배분해야할필요성을한층더크게느꼈습니다.육아,회사일,개인사업등바쁜일상에서생산성을높일수있는도구와시스템이필요했는데,바로그때AI를활용한여러가지업무효율화방법을접한것입니다.지난날프로그래밍에좌절했던제가다시‘무언가를만드는일’에도전할용기를얻은것도바로AI기술덕분입니다.AI는‘무엇을하고싶은지’말하기만하면그것을실현할수있도록도와줍니다.이런큰변화덕분에저처럼개발과멀어졌던사람도완전히새로운방식으로앱개발에도전할수있습니다.이흐름은결코일시적인유행이아니며,앞으로더욱확산되리라고확신합니다.AI등장이전에는앱개발에높은기술장벽과투자비용이따랐고,개인이추진하기어려운막대한노력과사전준비가필요했습니다.하지만AI시대에는이런상식이크게변화될것입니다.노코드/로우코드도구와대화형AI가결합되면서개발자가아니더라도저비용으로빠르게자기손으로아이디어를구체화할수있게되었습니다.
