Every clue placed
with purpose.
Suspects, alibis, red herrings, layered timelines. OpenAtelier tracks the architecture of your mystery so every reveal lands exactly as planned.
TABLEAU
Track clues, alibis, and red herrings on one board.
Every scene on a card, every reveal in its place. See the case the way the reader will need to reconstruct it, and catch the contradictions before the editor does.
- Scenes as cards with status and word counts
- Bookmarks for the moments a clue is planted
- Drag and rearrange before the prose locks in

GRIMOIRE
The network of suspects, alibis, and red herrings.
Keep every character, motive, and false lead as a referenced entry. The case file the writer can flip through without losing the chapter.
- Categories for suspects, motives, and evidence
- Cross-references between people, places, and times
- A reference that stays at hand while you draft
Grimoire

LA PLUME
A second reader for the seam in the plot.
Ask whether the clue lands, whether the misdirection holds, whether the reveal is earned. A critical reading that pushes at the joints.
- A reader for misdirection and earned reveals
- Pen marks where a sharp editor would set them
- A prompt written for craft, not output
