- 02Customize
Solo or Duo + your words
- 03Create & review
Check cost → generate → download
1. Prepare photos and one birthday idea
Sign in first, then prepare one clear, authorized portrait per performer. Each pictured adult must have explicitly agreed to uploading and this AI use, including for a surprise.
Then choose one detail worth celebrating: a shared adventure, an affectionate running joke or something the recipient hopes to achieve.
2. Choose your performers and write the message
Choose Solo for one birthday greeting or Duo for a shared wish. Describe the occasion in a topic, or enter your own lyrics with separate A/B parts.
A playful birthday rap for my friend, who always arrives late but never misses karaoke. Mention our Friday nights and wish them a year of new adventures. Keep the teasing affectionate.
Keep Photo A paired with lyrics A and Photo B with lyrics B when preparing the request. Speaker assignment and timing can still vary. See the two-photo rap guide for the full role setup.
3. Check the quote, generate and review
Review the settings, displayed credit cost and permissions before generating. After generation and safety review, check the birthday message and download your MP4.
For field-by-field instructions, use the photo-to-rap video guide.
Make it their birthday message
Use the two short parts as a writing guide, then add a detail only your friend would recognize.
Opens the creator. Add your own authorized photos, enter a topic or lyrics, and review the settings and final credit cost. Nothing is generated automatically.

03 / Give it a personal detail
What should you write in a birthday rap?
A useful birthday message has three ingredients:
Someone you know A detail they recognize A wish that matters
Here is how that can become a short lyric. Choose a joke the recipient would enjoy hearing in front of other people; leave out private information and humiliating stories.
For a friend
Always late. Always brings snacks.
Late to the party, first with the snacks / Happy birthday—your crew’s got your back.
For your partner
The familiar fries thief.
You steal my fries, I save your seat / Happy birthday, my favorite teammate.
For a coworker
The one who keeps everyone calm.
When plans go sideways, you know what to do / Today we pause for a birthday cheers to you.
Writing examples only. These new lines have not been generation-tested.
Choose one idea rather than squeezing several memories into a short clip. Read the lines aloud; if you need to rush, try trimming them. Custom lyrics guide the performance, but exact wording, pronunciation and timing can vary.

04 / Watch before you share
Before you send it
- PeopleRecognizable appearance and appropriate expressions.
- MessageUnderstandable words, acceptable name pronunciation and the intended birthday wish.
- Duo rolesLines delivered by the intended performers.
- ToneA joke the recipient would enjoy others hearing.
- FileYour downloaded MP4 saved somewhere you can find it.
If a result misses the point, identify the specific issue before deciding whether to make another version. A shorter lyric may be a useful next attempt, but it does not guarantee a better result.
05 / The practical questions
Questions before you create
Will a photo copy my friend’s voice?
No. A photo alone does not supply their voice. Without recordings, RapPrism uses AI-generated voices. An optional authorized adult recording can guide vocal timbre, but exact similarity is not guaranteed. The featured example used no voice recordings.
Can two people take turns delivering the message?
You can submit separate A/B lyrics in Duo. Speaker assignment and timing can vary, so review the result before sending it.
How much does it cost? Is a subscription required?
RapPrism sells one-time credit packs. Generation cost depends on duration and resolution; matching Solo and Duo settings use the same rate. Check current pricing and the final quote before submitting.
Can I use someone else’s photo for a surprise?
You need rights to the image and each pictured adult’s explicit permission for uploading and this AI use. Voice recordings also require authorization. See the image and voice permission rules.
What if it fails—or I dislike the finished video?
Failed or timed-out charged tasks return their actual generation credits. A completed video you dislike is not automatically a failed task or a free retry. Service issues and cash refunds follow the refund policy.
