EM
Elena Marrow
Protagonist — noir detective in a city that never dries
Voice profile
Sharp-witted, uses sarcasm as armor
Speaks in short clipped sentences
Never says "sorry" unless she means it as a threat
Uses concrete sensory details, not abstract feelings
Calls everyone by their last name; first names are earned
"Rain makes people honest. You can't lie when you're wet."
!
Voice break detected
She stood in the doorway for what felt like forever. Her heart was beating so fast and she felt really nervous about what she might find inside. "I'm sorry," she whispered to no one in particular, "I'm sorry I couldn't get here sooner." She walked slowly across the room, her emotions overwhelming her senses.
Ghost Reader analysis
Voice break detected: 3 abstract-emotion violations, sentence-length spike (18 words vs. Elena avg 7), missing sensory-concrete anchor.
✓
Suggested revision
Three seconds in the doorway. Four. The rain from her coat bled onto the floorboards. "Late," she said to the empty room. Not sorry — she didn't do sorry for timing. She crossed in five steps, cataloguing: overturned lamp, ash tray still warm, a single heel print near the window.
02
Before/after continuity audit
Firstory scans your manuscript for contradictory character traits across chapters. Below is a sample audit showing three breaks Firstory caught — each one a reader-experience problem a human beta reader might miss.
| Character | Contradiction | Chapters | Verdict |
|---|---|---|---|
| Elena Marrow Apologizes when upset | See Ch.3: "I'm sorry," she whispered Violates Ch.2 canon: "She didn't do sorry" | Fix suggested | Break — Firstory caught it |
| Elena Marrow Uses long flowing sentences when emotional | See Ch.3: 18-word sentence about her heartbeat Violates Ch.1-2 avg 7 words/sentence | Fix suggested | Break — Firstory caught it |
| Detective Chen References the "Riverside case" | Ch.1: "Like Riverside all over again" Ch.5: "Reminds me of the Harbor case" — wrong name | Fix suggested | Break — Firstory caught it |
03
Revision diff visualization

After (Firstory revision)
Three seconds in the doorway. Four. The rain from her coat bled onto the floorboards. "Late," she said to the empty room. Not sorry — she didn't do sorry for timing. She crossed in five steps, cataloguing: overturned lamp, ash tray still warm, a single heel print near the window.

What Firstory remembered
Canon memory tracks every fact about your story world — character details, timeline events, location descriptions — and flags conflicts the moment they appear. Locked facts are verified across multiple chapters; corrected facts were fixed after Firstory caught a drift.
| Canon fact | Appears in | State |
|---|---|---|
| Elena carries a .38 revolver — never a semi-auto | Ch.1, Ch.3, Ch.7 | Canon locked |
| The city has been raining for 47 days straight | Ch.1, Ch.2, Ch.5 | Canon locked |
| Chen's daughter is named Mei — she's 8, not 12 | Ch.2, Ch.6 | Canon locked |
| The Harbor case happened in winter, not summer | Ch.1, Ch.4 | Corrected |
| Elena lives above an all-night diner, not an apartment complex | Ch.1, Ch.3 | Canon locked |
| The antagonist was first seen in Ch.2, not Ch.4 | Ch.2, Ch.7 | Corrected |

Why did I build this:
As an avid reader of both traditional stories and fan fiction, I often found myself at a creative crossroads—frustrated when narratives veered away from my vision or when I exhausted the engaging content available online.
The problem was not a lack of AI help. It was that generic tools kept dropping context. Characters slipped out of voice, revision experiments buried good scenes, and each session started with too much re-explaining.
Firstory is my attempt to build the story-native workspace I wanted for long-form fiction and fanfic: character context that stays loaded, revision recovery that preserves what worked, and AI that supports the writing process without taking over the story.
The launch is intentionally narrow. I want early feedback from writers who care deeply about character consistency, scene continuity, and keeping their own voice intact while using AI.
Use Cases
AO3-focused
Keep Character Voice Stable Across Multi-Chapter Fanfic
Track character voice, relationship dynamics, and recurring canon details without re-explaining the same story context every session.
Revision recovery
Compare Draft Paths Without Losing the Scene That Worked
Review alternate revisions side by side so continuity fixes, style experiments, and AI suggestions do not erase your strongest draft choices.
Story-world context
Write Long-Form Fiction With the World State Still Loaded
Carry characters, locations, themes, and scene context forward so each drafting session starts from the right story state instead of a blank chat box.
Trusted by writers
Built with writers, validated by writers.
We are in early validation with AO3 and indie authors. Be one of the first to shape the platform.
Trust, not theater
Built in the open. Verified through real writing.
Firstory is still in early validation, so this page avoids padded social proof. We would rather show a narrower promise now and add stronger evidence as early writers and published stories generate it.
Early launch, not fake certainty
We only want proof we can defend.
Firstory is still in early validation. We are replacing placeholder hype with verified quotes, before-and-after artifacts, and approved case studies as they arrive.
Built from real writing workflows
The current product focus is narrow on purpose.
Character consistency, revision recovery, story-world context, and AO3-friendly workflows shape the product and the launch demo. We are not pretending to be a generic AI writing tool.
Proof comes from usage
The next trust layer comes from writers using it in public.
We are collecting proof from early writers, Story Doctor pilots, and published AO3 story output so the next iteration of this page can show evidence instead of filler.

Simple, honest pricing
Pricing built around real AI usage
Each plan combines a base subscription with an included monthly AI budget. If you use more, metered overage is billed in the same unit.
Each plan includes AI credits that cover model usage. Credits are denominated in USD-equivalent usage — roughly what the underlying AI models cost to run. The included credit amount exceeds the subscription price because we optimize model selection, prompt caching, and token efficiency to give you more value than raw API calls would provide.

Frequently asked questions
- What are AI credits?
- AI credits cover the underlying model costs — roughly what the AI models cost to run. The included credit amount exceeds your subscription price because we optimize model selection, prompt caching, and token efficiency to give you more value than raw API calls.
- What happens when I run out of credits?
- We alert you at 80% usage. At 100%, AI features pause automatically so you never get a surprise bill. You can enable overage in your billing settings if you want uninterrupted access — otherwise, your credits reset on your next billing date.
- Can I change plans?
- Yes. Upgrade or downgrade anytime from your billing settings. When you upgrade, the new credit amount takes effect immediately with prorated billing. When you downgrade, the change applies at the end of your current billing cycle.
- Do unused credits roll over?
- No, credits reset each billing cycle. This keeps pricing predictable and lets us maintain the credit-to-price ratio that gives you more value than what the models cost to run.

FAQs
Who is Firstory for?
Firstory is currently best suited to story-first writers, especially AO3 and fanfic writers working on multi-chapter fiction who care about character voice, continuity, and keeping story context stable across sessions.
How does Firstory work?
You define the core story context first, then draft with AI support that can reference your characters, story world, and revision history. Instead of starting from a blank chat every time, you keep writing with the relevant story state already in place.
What types of stories can I create with Firstory?
The strongest fit right now is long-form fiction where continuity matters: fanfic, serial fiction, and other story projects with recurring characters, locations, and relationship dynamics. Broader writing workflows may come later, but that is not the current launch focus.
Do I need writing experience to use Firstory?
No professional writing background is required. The product is designed to help writers who have ideas and strong taste but want more support with continuity, story context, and revision recovery.
Can I export my stories from Firstory?
Yes. Firstory supports exporting your work to standard formats so you can keep editing, publish elsewhere, or back up your drafts outside the product.
How long does it take to complete a story with Firstory?
That depends on your workflow and project length. Firstory is better framed as a tool for reducing continuity friction and revision loss than as a promise to finish a story in a fixed amount of time.
How does your platform compare to alternatives like NovelCrafter, Sudowrite, and NovelAI?
Those tools offer AI writing help, but Firstory is being shaped around story-native workflow problems: persistent story context, character consistency, revision recovery, and writer-led control. The goal is not to be a generic AI writing workspace with fiction bolted on.
What is the current launch stage?
Firstory is in early validation with open signup through /start. The product, proof bank, and onboarding flow continue to tighten around a narrower story-first use case.
Will the AI take over my creative process?
No. Firstory is designed around writer control. The AI can help with context recall, drafting support, and revision assistance, but your story decisions, voice, and judgment stay with you.
Will my stories and writing be used to train AI models?
No. Firstory does not use your stories or writing data to train AI models. Your content stays yours, and any model providers used for generation are used to serve your request, not to build training datasets from your work.
