Summon Worlds is the world builder and story planner for fantasy writers who want their fictional universe as organized as the story they're creating. No ads, ever.

Is your fantasy world scattered across a dozen apps? Notes here. Characters there.

Your world building deserves better.

= YOUR PERSONAL FANTASY KNOWLEDGE BASE =
Your second brain notes. Build privately or publish when you're ready, let the community explore, follow, & get inspired. A worldbuilding knowledge base where every entry connects:

- Characters linked to their locations, factions, and items
- Locations tied to the characters who inhabit them and the lore that shapes them
- Weapons, armor, and spells connected to the characters who wield them
- Your entire world building in one place, not ten different notes apps
- The more you build, the more powerful it becomes. Reference anything instantly. Nothing gets lost.

= EVERYTHING YOUR WORLD CONTAINS =
- Characters: heroes, NPCs, villains, monsters. Set race, class, gender, and alignment, as well as legendary details.
- Locations: cities, dungeons, forests, landmarks. Render scenes in 3D Panorama.
- Weapons, Armor and Items: swords, shields, treasures, consumables, magical gear.
- Spells: magical abilities with descriptions and art.
- Collections: group related entries to keep your worldbuilding organized.

= YOUR OWN CREATIVE AI =
When you need to move faster, AI steps in:

- Full Character Development in Less Than 1 Min: add names, backstory, stats, skills, notes & more
- Generate AI art in any style: Epic Fantasy, Anime, Photorealistic, Steampunk, or your own Custom Image Prompt
- Use Style Chips to fine-tune your AI image generation, or enhance for higher quality
- Use writing prompts and AI suggestions to push through creative blocks
- Let AI fill the gaps so you can focus on the story, not the setup

= A STORY PLANNER BUILT FOR BOOK WRITING =
Every tool you need from first idea to finished draft:

- Story planner with notes, plot points, and scene structure tied to your world
- Character creator, fully customizable for fantasy writers: DnD stats, history...
- World builder for locations, regions, and maps connected to your lore
- Story ideas capture: log notes, writing prompts, and scenes as they come
- Book writing support: build your narrative while your world takes shape

= YOUR CHARACTERS SPEAK BACK =
Every character can be chatted with directly. Not a generic chatbot. This is an AI that knows your character's backstory, stats, lore, and the world they live in, with adjustable memories.

- Regular Chat: light and fast. Quick roleplay, testing a character's voice, exploring story ideas.
- Bound Chat: full context. Your character knows their World, Location, equipment, and the characters around them. Enable World Knowledge to pull in your entire worldbuilding knowledge base.
- Generate AI images from dialogue. Voice response and mature mode available.

= BUILD WORLDS WITH OTHERS =
Convert any World into a Shared World and invite co-authors to build together in real time. Multiple contributors, one connected worldbuilding knowledge base: characters, locations, lore, all in the same universe.

= WHO BUILDS WITH SUMMON WORLDS =
- Fantasy novelists who need their world building as organized as they imagine it, lore, characters, and locations linked across a series.
-Story planners and book writing enthusiasts who've outgrown Campfire, Obsidian, Notion, or other note-taking platforms.
- Game and Dungeon masters who need a DnD Character Creator for their campaigns.
- Worldbuilders who want a personal fantasy knowledge base they can reference while writing.
- Writers who want story AI that knows their world, not a chatbot starting from scratch.

Ratings and reviews

Trying to summarize what's happened into lines fitting under 500 characters can be really hard. Wouldn't mind if y'all added an AI assistant feature there that can help you analyze the game so far and help summarize what the AI has learned about the world so far, in a format that works to be read by the LLM. Like, some impressions should last, but can be summarized over time "he put a sword to her throat" could be summarized as "threatened me when we met" to "first impression threatening".

It's a good start. The point system (hit points, armor, etc) seem arbitrary since they haven't factored into any of my encounters in the app. I can't figure out what to do with the items and the locations. They don't seem to do anything in the narrative. But, the synergy of the image, character and description generations is pretty impressive.

It's overall a pretty good app, but it's pretty annoying how the AI has to always be the hero and overrides almost every decision I make. It also gives me really long paragraphs and repeats the same sentences, while on the other hand, I can hardly write anything. They basically make their character undefeatable. I just want to have fun with my characters while the AI sticks to what that character is supposed to do, feel, act like, and say.
