Build the work around your context

Give the task a foundation, choose a useful output and refine it with specific feedback.

Start with the material that matters

Use relevant notes and documents as the basis for writing or analysis. Distinguish source evidence from your instructions, and ask for uncertainty to stay visible when the material does not support a conclusion.

Choose the form that fits the job

An article explains an idea, a decision brief weighs options and a webpage makes a concept usable. Ask for the output you actually need and name the parts that will make it useful to the next reader.

Refine with a specific next request

Ask for a shorter argument, a clearer structure or a different interaction. Explain what should stay as well as what should change so each revision moves the same piece of work forward.

From your starting material to useful work

Set the task and context
Describe what you want to make, who it is for and what a useful result should contain. Include the purpose and constraints in your starting brief.
Continue with your source material
Choose Try in YouMind to open the task with this model and your brief. Add the notes or documents you need there, then ask for a specific deliverable such as an article, decision brief or webpage.
Review and refine the result
Read the argument, check the sources or open the rendered artifact. Give feedback on a specific part, then verify the revised work before sharing it.

What our users say

I bring interview notes to Claude Opus 5.5 and ask for an article built around the strongest tension in the story. The useful part of AI writing for me is having a draft I can question, reshape and make my own.
Noa GalEditorial writer
My research notes were scattered across documents. Asking for a brief organized by agreement, disagreement and open questions gave me a clearer way to read them. I still go back to the original sources when a claim matters.
Priya NairResearch analyst
For webpage prototyping, I give Claude Opus 5.5 the audience, content and one interaction to focus on. A workshop registration page became much easier to discuss once there was a working layout to review.
RaviProduct designer
I wanted motion graphics made with code: a headline appearing as a line traces a circle. Describing the timing and asking for an HTML and CSS animation let me work on the sequence as something I could open and inspect.
Sofia HerreraCreative developer
Claude Opus 5.5 helps me turn a broad planning discussion into a decision brief. I ask for the options, tradeoffs and assumptions to sit beside each other. That structure makes the next team conversation more focused.
Theo NguyenTeam lead
An outline with an argument beats a list of topics. That's what I ask for before building a presentation.
Zara P.Workshop facilitator
A grant proposal has to connect a problem, a plan and a budget. I give Claude Opus 5.5 my working notes and ask where that chain is unclear. The questions it raises are useful before I write the final application.
Amir HaddadCommunity project coordinator
I ask for a lesson plan around one idea students often misunderstand. Starting with that misconception gives the activities a purpose. I check the examples against my teaching materials and adapt them for the class.
Beatriz CostaTeacher
After a planning meeting, I want decisions, owners and unresolved questions in separate groups. Claude Opus 5.5 helps me organize the notes without turning every discussion point into a decision we never made.
Dario SilvaProject manager
For AI code review, I share the function and explain its contract. I ask about empty inputs, failure paths and assumptions before requesting a rewrite. The result gives me questions to test against the code, not a reason to skip testing.
Elise MartinSoftware developer
The same product update needs a different opening for a customer email and an internal note. I use Claude Opus 5.5 to explore that change in emphasis while keeping the facts and the action I need from each reader intact.
Farah MansourProduct communications writer
Would a new teammate know what to do next? That is the question I ask when reviewing a setup guide. A second pass over the missing steps is often more useful to me than a polished introduction.

Questions before you start

Can I start from my own notes or documents

Yes. Bring the relevant material into the task and explain how it should be used. Say which facts or passages matter, what the output is for and what should not be added.

How do I get writing that reflects my point of view

Provide the central argument, audience and tone, along with a sample where useful. Ask for a structure before a long draft if the direction is still taking shape, then refine the parts that sound vague or unlike you.

How should I check a research brief

Ask for source references beside important claims and a clear separation between evidence and interpretation. Open the cited material, check whether it supports the claim and verify any date or figure that affects the decision.

Can I ask for a webpage rather than an explanation

Yes. Specify the purpose, content, layout and interactions you need. Review the rendered page on the screen sizes that matter and test its links and controls. Generated code still needs a practical review.

Does code based motion mean native video generation

No. A code based animation defines elements, movement and timing in code and is rendered with the relevant tools. Use a video generation model when the task calls for generated footage from a prompt or reference image.

How does using this model affect credits

Model usage consumes your account credits. A task that also generates images or video can use additional credits for those tools. The pricing section shows current plans; a free Skill does not make the underlying model usage free.
