Independent tool overview
AI Story Plus Step II (formerly OpenStorytelling Plus) at a glance
OpenStorytelling Plus is an established custom GPT that now appears publicly as AI Story Plus Step II under the same GPT identifier. Created by Bryan Harris, it acts as an interactive mentor for story and screenplay ideation, outlining, character development, scenes, dialogue, subtext and theme. It is useful for guided practice and alternative drafts, but writers should preserve authorship, verify any factual or format guidance and avoid uploading confidential scripts without reviewing ChatGPT data controls.

Overview
What AI Story Plus Step II (formerly OpenStorytelling Plus) is
OpenStorytelling Plus launched as a screenplay-writing guide built from curated storytelling material and real screenplay examples.
The same public GPT identifier is now listed as AI Story Plus Step II, expanding its description to stories, novels, film, television, short-form and digital narratives.
Its guided subjects include ideation, outlining, plot structure, character development, scenes, subtext, dialogue and theme exploration.
The original learning framework emphasized a four-act, 24-block screenplay structure, with six blocks per act and roughly five-minute blocks for a feature-length script.
Knowledge files give the GPT specialized reference material, while the current listing also advertises web browsing, image generation, file upload and data-analysis capabilities.
Writers can ask for a syllabus, develop a premise into an outline, workshop a scene or request critique against a specific dramatic goal.
Generated images can support mood, character and scene exploration, but they are concept references rather than production-ready rights clearances or storyboards.
The tool runs inside ChatGPT and does not have a separate OpenStorytelling subscription; access, models and limits follow the user's ChatGPT plan and workspace rules.
OpenAI currently lets signed-in Free users use existing public GPTs, subject to plan and tool limits; a higher-tier plan provides more capacity but does not guarantee a particular creative result.
Custom GPTs start each conversation without ChatGPT saved memory, custom instructions or previous chats, so important story decisions should be restated or kept in the writer's own project bible.
The GPT should be treated as a brainstorming and teaching aid, not as the credited author, a copyright clearance service or a substitute for professional script feedback.
Availability, identity and ChatGPT access rules were checked on August 31, 2026.

Describe the format, audience, genre, length and creative question rather than asking for an entire finished work.
Step 2
Protect private material
Remove confidential deal details and review ChatGPT data controls before uploading an unpublished script.

Develop the premise
Clarify protagonist, objective, opposition, stakes, setting and transformation.

Assessment
AI Story Plus Step II (formerly OpenStorytelling Plus) strengths and limitations
Where it stands out
- Provides a focused screenwriting conversation instead of a generic blank chat.
- The 24-block framework gives beginners a concrete way to reason about feature pacing.
- Supports ideation, outlining, characters, scenes and revision in one thread.
- Specific diagnostic prompts can surface alternate explanations for a weak scene.
- Multiple generated options can help a writer escape a local creative block.
- Knowledge files provide more specialized context than an unconfigured assistant.
- File upload allows feedback on the writer's own material within account limits.
- Image generation can make settings and tonal ideas easier to discuss.
- The interactive format lets beginners ask basic craft questions without embarrassment.
- It can turn general craft concepts into exercises for classes or writing groups.
- Free ChatGPT users can access existing public GPTs under current rules.
- The rebranded GPT expands beyond screenplays to other narrative formats.
What to consider
- The public identity has changed from OpenStorytelling Plus to AI Story Plus Step II, which can make older descriptions look outdated.
- The tool is a custom GPT inside ChatGPT, not a dedicated screenplay editor with industry-standard pagination and revision controls.
- A single 24-block framework will not fit every film, episode, novel or interactive story.
- Generated plots and dialogue can be generic, repetitive or tonally inconsistent.
- The model can invent screenwriting rules, citations, facts or claims about example scripts.
- It does not remember prior conversations or saved ChatGPT memory, so continuity must be supplied again.
- Long scripts may exceed practical context or upload limits and receive uneven attention across sections.
- Consumer-plan conversations may be used for model improvement depending on the user's data-control settings.
- Uploading unpublished or commissioned scripts can conflict with confidentiality, employer or client obligations.
- GPT builders cannot view individual chats, but enabled third-party apps or actions may receive relevant input; check the live GPT details before sharing data.
- Image output does not establish trademark, likeness or copyright clearance.
- Requests to imitate a specific writer can create derivative, ethical and professional concerns.
- AI assistance may violate a course, contest, fellowship, guild or employer disclosure policy.
- Automated feedback cannot reproduce a table read, audience reaction or experienced script editor's judgment.
- Free-tier GPT and advanced-tool access can pause when plan limits are reached.
- The creator can update instructions or knowledge, and OpenAI can change the underlying model without preserving identical behavior.

AI Story Plus Step II (formerly OpenStorytelling Plus) FAQs
What happened to OpenStorytelling Plus?
The same custom GPT identifier is now publicly listed as AI Story Plus Step II by Bryan Harris. The original screenwriting focus remains part of its broader story-development description.
What does it help writers do?
It supports story ideas, outlines, characters, plot structure, scenes, dialogue, subtext, themes, feedback and visual concepts.
What is the 24-block structure?
It is a four-act feature-screenplay framework with six roughly five-minute story blocks in each act. Treat it as one planning option, not a universal rule.
Is OpenStorytelling Plus free?
There is no separate tool price. Signed-in ChatGPT Free users can use existing public GPTs under current plan limits; paid ChatGPT tiers offer higher limits.
Do I need ChatGPT Plus?
No under current access rules. Free users can use public GPTs, but GPT, file, image and analysis limits are lower and may pause until reset.
Can it read my screenplay?
It can work with supported uploads within the account's limits. Remove sensitive information and verify your confidentiality and data-control requirements first.
Does it remember my story?
Not across separate conversations. Custom GPTs do not use saved memory, custom instructions or previous chats, so keep an external story bible.
Can it format a production-ready screenplay?
It can suggest screenplay text and structure, but a dedicated screenwriting application is better for exact formatting, revisions, locking and production workflows.
Can I submit AI-assisted work?
That depends on the relevant school, contest, guild, employer, client and distributor rules. Review them and disclose assistance when required.
Does it own my story?
This review does not determine ownership. Keep authorship records and consult the applicable ChatGPT terms, contracts and local law for the intended use.
Are its screenplay examples safe to copy?
No blanket assumption is safe. Learn from structure and technique, verify the source license and avoid reproducing protected expression.
Who should use it?
It is best for writers and students who want an interactive craft guide and are prepared to make, verify and own the final creative decisions.
Bottom line
Our AI Story Plus Step II (formerly OpenStorytelling Plus) verdict
OpenStorytelling Plus—now AI Story Plus Step II—is most valuable as an always-available story workshop: it can teach a concrete structure, ask productive questions and generate alternatives quickly. It is not a substitute for dedicated script software, human notes or authorship discipline. Use it to challenge and expand your thinking, then rewrite, verify and document the final work yourself.
