Private founder diary
Write private notes about the build, including wins, bugs, doubts, and other behind-the-scenes moments.
BuildBook
BuildBook is a web app for founders and solo builders to keep a private build diary and turn selected moments into public posts. It also supports voice-based drafting and a Ghibli-style image feature for build updates.
Overview
BuildBook is a founder diary for logging the day-to-day reality of building a product in private, then turning those notes into public posts. The home page frames it as a way to share raw, unfiltered behind-the-scenes moments instead of only polished launch updates.
The product centers on a timeline of short entries that can include text, mood, and media, plus a draft flow for shaping those moments into posts for platforms like LinkedIn, X, and Reddit. It also includes a separate Ghibli-style image generation feature tied to build moments.
Core features
Timed timeline entries
Add a mood, a screenshot, or other media to a note, then save it with the date and time on your timeline.
Diary to post conversion
Turn diary moments into public posts that sound honest and specific rather than polished marketing copy.
Voice and style selection
Choose a target voice such as LinkedIn, X, or Reddit, or describe a custom voice before drafting content.
Ghibli-style moment art
Generate Ghibli-style art from a build moment and apply a BuildBook watermark.
