The most useful and lowest-risk AI for teachers takes over the writing around teaching: letters and emails to families, replies to parents, notes from staff meetings and translated notices. You say what the message should contain, and the AI turns it into a clear, friendly text you check and send. Two limits apply: AI should not grade students' work, and students' personal data only goes into tools your school or district has approved. Retexta is an Android app for exactly this kind of writing: you talk, it writes the finished text.
| Your task | What you do | Retexta goal | Where to find it |
|---|---|---|---|
| Letter or email to families | Speak the facts: what, when, what to bring | Write a message, type Email, style Warm or Friendly | Start screen |
| Reply to a parent's email | Paste the email, say what you want to answer | Reply to a message | Start screen |
| Notes from a staff or department meeting | Speak your summary right after the meeting | Summarize a meeting | Start screen |
| A long circular from the district | Upload it as a screenshot or PDF | Explain something | Start screen |
| The same notice in another language | Paste the finished letter, pick the language | Translate | More templates |
| Your to-do list after a busy day | Speak everything that is on your mind | Take notes, then Task list | More templates |
Three rules before you start
1. No grading. Deciding how good a student's work is stays with you. Germany's education ministers (the Kultusministerkonferenz) wrote in their 2024 recommendation on AI in schools that grading "is and remains" a task that only teachers can carry out (our translation). Retexta is not built to assess student work, and we do not recommend using it for that.
2. Student data stays out unless your school says yes. Names, grades, health information, learning needs and family details are personal data. In the US, FERPA gives parents "some control over the disclosure of personally identifiable information from the education records". Other countries have their own rules, and your school or district has a policy. Until you know what it allows, use placeholders like [Student] and [Parent] and add the real names yourself after you copy the text out.
3. Do not record children. Recording a lesson or a conversation with students needs your school's approval and the consent the school requires, usually from parents. The safe way: speak your own notes after class. Retexta's privacy policy also says the app is not intended for children, so it is a tool for you, not for your students. UNESCO's 2023 guidance on generative AI in education likewise recommends an age limit for students' independent use of such tools.
Example 1: a field trip letter to families
We wrote these examples ourselves to show the idea. They are not real app output, and your results will look different.
What you might say (Write a message, Email, Warm):
Letter to the families of my fourth grade class. We're going to the science museum on Thursday, October 15. Bus leaves at 8:45, back by 2:30. Kids need a packed lunch and a water bottle, no glass. Permission slip back by Friday, October 9. Cost is covered by the school. If a parent wants to come as a chaperone, email me, we need two more. Keep it friendly and short.
The finished letter:
Subject: Science museum trip on Thursday, October 15
Dear families,
our class is visiting the science museum on Thursday, October 15, and we're looking forward to it.
- The bus leaves at 8:45 am, and we'll be back by 2:30 pm.
- Please pack a lunch and a water bottle (no glass).
- The trip is paid for by the school.
Please return the signed permission slip by Friday, October 9.
We're still looking for two chaperones. If you'd like to join us, just reply to this email.
Thank you, and best wishes,
[Your name]
Everything came from the voice note. The AI added the order, the greeting and the list. Check the dates and times against your planning before you send it.
Example 2: a calm reply to a worried parent
The parent's email (pasted into Reply to a message, names replaced):
Hi, [Student] came home upset again because she didn't finish the math test in time. This is the second time. Is she getting enough help? I'm really worried.
What you tell it (in What do you want to achieve?, typed or spoken with your keyboard microphone):
Reply friendly and calm. Thank her for writing. Say I noticed [Student] works carefully but slowly on tests, and that's something we can work on. Offer a short meeting, Tuesday or Wednesday after school, 3:30. Don't promise extra test time, I have to check that with the team first.
The finished reply:
Dear [Parent],
thank you for writing to me, and I'm sorry [Student] came home upset.
I've noticed that [Student] works very carefully on tests, which sometimes means she runs short on time. That is something we can work on together.
Could we meet briefly to talk about it? I'm available on Tuesday or Wednesday at 3:30 pm after school. Please let me know what suits you.
Best regards,
[Your name]
Notice what the reply leaves out: the note about extra test time. You told the AI not to promise it, so it is not in the text. Always check that nothing slipped in that you did not say.
Example 3: from a staff meeting to a task list
Right after the meeting, open Summarize a meeting and speak your own summary instead of recording colleagues:
Grade four team meeting, September 24. Parent conferences are on November 5 and 6. Everyone sends their time slots to Mr. Adams by October 10. We agreed on one shared reading log for all classes, Ms. Kim prepares it by October 1. Still open: whether we do the winter concert again, we'll decide next time.
Retexta writes a protocol with a summary, decisions, action items with owners and dates, and open questions. If you want to know which format fits a meeting, see types of meeting minutes.
Report card comments: wording, not judgment
Many teachers ask whether AI can write report card comments. Here is where we draw the line: the assessment is yours, and the AI only helps with the wording. If your school allows it, speak what you already decided, without the student's name ("[Student] reads fluently, struggles with longer written answers, very helpful in group work, next goal: plan answers before writing"), and ask for a clear, kind comment. Then add the name and check every sentence against what you really observed. If your school has rules on report wording or on AI, those come first.
Free AI for teachers, worksheets and lesson plans
- Free: Ask your school or district first; some provide approved AI tools. Retexta is free to try: new users get a few free Pro results to view in the app. Copying, sharing, exporting and everything after the free results need Retexta Pro or credits.
- Worksheets and lesson plans: Retexta is not built for worksheets or lesson planning. It turns what you say, paste or upload into letters, replies, notes, summaries and translations. For worksheets, a dedicated tool fits better.
How to write a parent letter in Retexta
- Open Retexta and tap New task.
- Under What do you want to do?, tap Write a message.
- Under What kind of message?, choose Email and a writing style such as Warm or Friendly. Tap Next.
- Tap Record audio and say what the letter should contain.
- Stop the recording. Retexta transcribes what you said on its servers and writes the letter.
- Change the style, language or length on the result screen if needed, read the letter, then copy or share it to your email.
For families who speak another language, open More templates, tap Translate, paste the finished letter and choose from 50+ output languages. Ask a colleague or family member who speaks the language to read important notices before they go out, because AI translations can contain mistakes. More on this: voice to text in another language.
Every goal except Transcript only is part of Retexta Pro. Copying, sharing and exporting results needs Retexta Pro or credits.
Where your text goes
Retexta processes recordings and text in the cloud: according to its privacy policy, requests go through FLAME Apps' Google Cloud infrastructure to AI providers such as OpenAI, and your note history is stored on your phone. Read the Retexta privacy policy and your school's rules before you put anything about students into it.
