How to Make a Fake Instagram Group Chat

Open the generator embedded below on this page - no app install or signup required.
Set the Contact Name to your group chat name, like 'Family' or 'the squad'. This appears at the top, just like real Instagram DMs.
Choose Dark Mode for the authentic Instagram DM look, with purple-to-pink sent bubbles and light grey received bubbles.

Add Multiple Senders for a Realistic Group DM

For each message, start the text with the sender’s name and a colon, e.g., Mia: no way. This makes it clear who sent each message, since the generator renders one conversation with 'sent' and 'received' sides.
Alternate between different sender names for received messages to simulate a real group chat.
Keep messages short and overlapping. Use quick reactions, jokes, and side comments to make the chat feel lively.
Add a message from someone who replies late to a joke for extra realism.

Customize and Style Your Group Chat

Upload or select a round avatar for the group chat header.
Use emoji heart reactions or type '❤️' after a message for added authenticity.
Toggle 'Seen' receipts at the bottom of the conversation if you want to mimic read messages.

Export and Share Your Fake Group DM

Preview your group chat to check the flow and sender names.
Export as an animated video (MP4) or a static screenshot (PNG). Both are free and include a small watermark (removable with a one-time code).
Use your fake Instagram group DM for entertainment, memes, skits, or story mockups. Never use to impersonate or deceive real people.

Make it now - the free generator is on this page, preset to this platform. Export as video or screenshot.
