Hồi Sau

Hồi Sau runs original AI characters as a daily office-comedy comic for young Vietnamese workers. Meta's Muse models write, draw and check each episode; it is posted to Facebook, Instagram and Threads; the comments are screened, scored and grouped, and the best idea becomes the next episode, with its author written in as a coworker. The problem. Young office workers in Vietnam share relatable workplace jokes every day, and a recurring character is the format that builds a following. But a character that posts daily is a full-time job by hand, and since July 2025 YouTube and Meta demonetize mass-produced, unoriginal AI content. Creators are stuck between burning out and being flagged as AI slop. What we built. Hồi Sau is a small comic studio on Meta's models, running one loop a day: 1. Writers' room. Muse Spark writes premise, beats, panel script and storyboard as strict JSON, against a series bible and story memory, and against the bibles of the characters in the episode. 2. Drawing. Muse Image draws each panel with no text, using each character's locked model sheet as a reference and chaining every panel from the last, so the characters stay on-model. 3. Review. Muse Spark vision checks each panel against the model sheets. A failed panel is fixed as an edit turn that changes only what is wrong. 4. Lettering. Vietnamese dialogue is fitted into the bubbles as an SVG layer with a real font, because image models mangle Vietnamese diacritics. 5. Publishing. Each episode goes to Facebook, Instagram and Threads through Meta's official APIs, with a journal that prevents double posting. 6. Listening. A rule screen drops spam and abuse; Muse Spark Open scores the rest for idea, fit and fun; ideas wanted by many different people win. The commenter is credited and drawn into the next episode as a coworker. 7. Coaching. The coach compares strong and weak episodes and writes lessons that go back into the writer brief. The same cast also makes short videos: Muse Spark plans the shots, Muse Image draws them, SAM 3.1 pastes back only the mouth and eyes, and MusicGen scores the clip. Results. In its first week, on brand-new Pages with no ads, the studio made 28 episodes and posted 22 short clips to Facebook, Instagram and Threads: 2,098 views so far, with 14:00 the best posting hour. No comments have come in yet, so every direction this week was set by us; the comment loop is built and shown in the demo on sample comments with the real model.
