Strict JSON validation

Every pack is validated against a defined schema. No malformed output. No guessing if the structure is right.

◈

Beginner-first design

Simple dropdowns: genre, tone, role. The rest is handled for you. No technical knowledge needed.

↭

Smart assumptions

Enable "fill in the gaps" and RenForge handles vague ideas. Disable for full control over every detail.

★

Branching dialogue

Each pack includes a dialogue tree with 3-7 nodes and branching paths. Actual game structure, not just lines.

✎

Plain language input

"A sarcastic pirate captain in a comedy visual novel." That's enough. We build the rest.

⚙

Ren'Py native

Output is structured specifically for Ren'Py. Not generic, not engine-agnostic. Ren'Py first.

Sample output

Here's what a generated character pack looks like. This is the actual JSON you'll receive.

{ "schema_version": "1.0", "input_summary": { "genre": "fantasy", "tone": "mysterious", "character_role": "mentor", "assumptions": [ "Character is an ancient forest guardian", "Speaks in riddles and metaphors" ] }, "character": { "name": "Sable", "archetype": "Reluctant Guide", "traits": ["cryptic", "patient", "haunted"], "backstory": "Once a scholar who wandered too deep into the Thornwood. The forest claimed her, but in return gave her sight beyond mortal years. She guides those who wander in, though she cannot leave herself.", "dialogue_style": "Speaks in layered metaphors. Rarely gives direct answers. Her tone shifts between warmth and eerie detachment." }, "dialogue_tree": { "start_node_id": "node_1", "nodes": [ { "id": "node_1", "speaker": "Sable", "text": "The forest remembers what you've forgotten.

Yes. The Thornwood is hungriest in autumn. I will help you -- but you must promise me something first.", "choices": [] }, { "id": "node_5", "speaker": "Sable", "text": "Follow the lanterns. They'll lead you deeper. Whether that's where you want to go... well. That's not my question to answer.", "choices": [] } ] } }
