Teach AI your voice and materials
Upload your slides, plans and writing. Get outputs that sound like you — not a generic AI.
Upload your world
When Claude or Gemini only knows what it was trained on, it gives generic answers. When you upload your materials, it learns your curriculum — and everything it produces is grounded in what you actually teach.
- Student names, photos, or identifying details of any kind
- Staff names, email addresses, or contact information
- Parent or guardian names, phone numbers, or home addresses
- Medical information, SEND assessments, or safeguarding notes
- Individual EHC plans or named support plans
- Disciplinary records or pastoral correspondence naming individuals
What to do instead: Replace names with generic labels such as "Student A" or "a Year 10 student" before uploading. Use anonymised examples for marked work.
What to upload, and why each thing matters
Different file types teach the AI different things. The following describes what each contributes to its understanding of your teaching.
How to create a Project in Claude and upload your files
The following steps get your content into a Claude Project so it is available in every conversation you start inside it.
- Open claude.ai (opens in new tab) and sign in to your account.
- In the left sidebar, find Projects and select New project.
- Give it a meaningful name — for example Year 9 Science or GCSE English Teaching.
- Select Add content and upload your files. Start with your most-used slides and two or three lesson plans.
- Add a project instruction — this is covered in full in phase three of this guide.
- Every new chat you start inside this project will automatically have access to all your uploaded files.
Teach your voice
Your teaching voice is the combination of how you explain things, how warm or formal you are, which analogies you reach for, and what you care about. Without it, the AI defaults to a generic tone that sounds like no particular teacher at all.
Upload examples of your own writing
The most powerful thing you can do is show, not just tell. Upload real examples of your writing from different contexts — the AI will read the patterns and learn them.
Ask the AI to identify your voice from your documents
Once you have uploaded some of your writing, paste the following prompt inside your project. The AI will read your documents and describe the patterns it notices, then give you a voice description paragraph you can reuse.
Or build your voice description here
Fill in the four questions below. When you select the generate button, this tool creates a voice description paragraph you can copy straight into your project instructions.
Build your project instruction
A project instruction is a set of standing rules the AI reads before every conversation. Think of it as the briefing you would give a very capable teaching assistant on their first day — covering your subject, your students, your style, and your non-negotiables.
The five parts of a strong teaching instruction
A well-built project instruction covers the following five areas. One to three sentences per area is enough.
- Who you are and what you teach. Subject, year group, exam board if relevant.
- Your students. Age range, typical prior knowledge, any key context about the group.
- Your voice. The paragraph you built or asked the AI to write for you in phase two.
- Your content. Tell the AI to use your uploaded materials as its primary source — not generic knowledge.
- Your rules. Format preferences, things to avoid, how formal outputs should be.
A ready-made template to edit
Copy the template below into your project's instruction box. Replace every section in square brackets with your own details. Delete any parts that do not apply to you.
A content-anchor phrase for individual messages
For any conversation where you want the AI to stay especially close to your materials, add this short phrase at the start of your message. It tells the AI your uploaded documents are the boundary, not just the starting point.
Use it daily
The following example prompts show how to phrase requests so the AI uses your materials and your voice. Each uses a pattern you can adapt for your own subject and context.
Creating new materials from your existing content
Writing a parent communication in your voice
Differentiating your own content
Generating feedback comments from your rubric
Building retrieval questions directly from your slides
Your setup checklist
Work through each item and tick it off as you complete it. By the time you reach the end, your project is fully set up and ready to use every day.
Setup checklist
- Created a project with a clear name for your subject or year group
- Uploaded your slides and lesson plans — at least five documents, with all personal data removed
- Uploaded examples of your writing — anonymised, with all student names, parent names, and contact details removed
- Built your voice description using the builder in phase two, or asked the AI to write one from your documents
- Added your project instruction including the data protection rule
- Checked every uploaded file for personally identifiable information and removed or anonymised it
- Tested with a real task — asked the AI to write something using your materials and checked the result
- Refined at least one output and noted what to add to your project instruction
- Planned what to upload next — next unit, more writing examples, your current assessment rubrics
What to do next
Once you are comfortable with one project, the following ideas help you get more from this setup.
