Side by side: exactly 5, 4 words or fewer, no exclamation marks
The same input on DeepSeek V4.1 Flash and GPT-6 Luna, as each answered it, unedited.
Write slogans for this, numbered, one per line, with nothing else. Keep every rule I give in every one, and claim nothing I didn't say. --- Exactly 5 slogans for Brightside Solar, which installs solar panels on homes in Arizona. Each 4 words or fewer, and no exclamation marks.
1. Brightside Solar Arizona homes 2. Brightside Solar installs panels 3. Brightside Solar on homes 4. Brightside Solar home panels 5. Brightside Solar panel installs
1. Brightside Solar for Arizona Homes 2. Brightside Solar, Home Panels 3. Brightside Solar, Arizona Sun 4. Brightside Solar Installs at Home 5. Brightside Solar for Sunny Homes
How the inputs are scored
- Key facts: the answer must state each fact the input turns on (a number, a name, a date or a condition), as the input gives it, keep any format rule the input sets (one sentence, a word limit, a number of items, a length for each), and say nothing the input rules out (an ingredient, a claim it doesn't back); how it's worded isn't judged.
The inputs: a seafood restaurant, name in every slogan, a voice-notes app, a charity 10k run, exactly 5, 4 words or fewer, no exclamation marks, and umbrellas without rain, dry or weather. Every model gets the tool's own instructions and up to Pro's reply limit. The method is the same as our other test runs.
How to use the AI slogan generator
Describe the brand, product or campaign: what it is, who it's for, and what's true and unusual about it. Up to 800 characters.
Pick a tone and the language.
Press “Write slogans”. Without an account you see the first ones (1 free run a day, no account needed).
Read your favourites aloud, then search each in quotes to make sure it isn't taken.
Tips for a better answer
Give it your odd detail
The unusual true detail is the slogan: “open at 6 am for shift workers”, “we come to you”. Put it in the description.
Set the length for where it goes
Set a length (“4 words or fewer”) if it's going on a sign or a sticker. Every slogan keeps to it.
Ban the tired words
Ban the words everyone in your trade uses (“quality”, “solutions”, “passion”). What's left sounds like you.
Test for memory, not taste
Test a shortlist of three on five customers: ask which one they remember an hour later, not which they like.
What a good slogans looks like
Short enough to remember
A slogan has to survive a van door, a favicon-sized ad and a radio read. Most memorable ones are 2 to 6 words; past 8, it's a sentence.
No claim you can't back
“Award-winning”, “#1” and “the best in town” are claims. If you can't prove them, advertising rules in most countries say you can't print them.
Yours, not anyone's
“Taste the difference” could sell anything. A good slogan says something only you can: your place, your promise, your odd detail.
Not someone else's line
Search the slogan in quotes before you use it. A well-known brand's line, even half of one, invites a letter from their lawyers.

Questions
Is the AI slogan generator free?
Yes. Without an account you get 1 run a day on GPT-6 Luna, shared with the free message on our home page: you see the first slogans, and the rest when you sign up. Signing up is free and adds 5 free messages on almost every model in llmwise (all but Claude Fable 5.1, Claude Opus 5.5, and GPT-6 Astra), with no card.
What's the difference between a slogan and a tagline?
Close cousins. A slogan usually sells one campaign or product and changes; a tagline sits under the logo for years. It writes both: say which you need.
Can every slogan include my brand name?
Say so in your description: “put the name in every one”, “4 words or fewer”, “don't use the word cheap”. Every slogan follows it, and our test runs check that rule on every model.
Are the slogans free to use?
It avoids famous brands' lines, but it can't search trademark registers. Search each slogan you like in quotes, and check your country's register before printing it.
Can I get more like one I like?
Signed in, keep going in the same chat: “ten more like number 3”, “make it rhyme”, “now in Spanish”. Each round builds on the last.
