Still awake? The thumbnail test is finished.
Yes, just checking the numbers. Which version won?
The darker one, by a clear margin.
When dark helps
Dark mode earns its place when the picture sits on something dark already: a night scene, a gaming clip, a dark slide theme or a video with a black background. A pale chat bubble block glares there, while a dark one blends in and lets the text carry. On a bright background, stay with light.
Which look this page uses
Dark mode is a setting, not a separate app, and this page applies it to the WhatsApp-style look. The look is on the Free plan, and the plans page lists dark mode among the Standard features, so check there for what your account allows. ChatsRat draws its own interface in a similar general style and uses the app name only to describe the layout, with no affiliation.
Keep text readable
Contrast is the point of dark mode, so test it. Export a PNG, shrink it to the size of a phone thumbnail and see whether you can still read the words. Short messages, at most two lines, hold up best. If you place the chat on top of footage, leave some space around it so it does not merge with the background.
Where it fits
Use it for text-story videos, thumbnails, night-time scenes in fiction, and presentation slides with a dark theme. Pick light for print handouts, bright rooms and projectors in daylight, where a dark image washes out and loses its edges. When you share the image, mark it as a simulated conversation, particularly if the scene could pass for a late-night message between real people.
Tips
- Choose dark only when the surrounding image is dark, so the chat does not stand out as a bright block.
- Check readability at thumbnail size before you finalise any text.
- Keep messages short, because small light text on dark gets tiring fast.
- Export one light and one dark version and compare them on the real background.
Questions
Is dark mode a separate chat style?
No. It is the colour scheme setting in the editor. This page shows it with the WhatsApp-style look, but you can switch most looks between light and dark.
Do I need a paid plan?
The WhatsApp-style look is on the Free plan. The plans page lists dark mode with the Standard plan features, so check what your account includes.
Why use dark mode for thumbnails?
It blends with dark artwork and keeps attention on the words. Test at small size to make sure the text still reads.
Is this connected to WhatsApp?
No. ChatsRat is not affiliated with, endorsed by or sponsored by WhatsApp. It draws its own layout in a similar general style.
Can I switch back to light later?
Yes. Change the colour scheme in the settings step and the preview updates at once. Export a version of each if you are unsure.
Use it for simulated, labelled content. ChatsRat makes mock-ups and fictional conversations for creators, designers and teachers. Do not use it to pass off a made-up conversation as a real one, to impersonate a real person, or as proof of anything. See the Acceptable Use policy.
About the watermark. Exports on the Free plan carry a visible ChatsRat watermark, and every export carries an invisible mark that the verify page can read. Plans list what changes on paid plans.
