Idlen vs ChatGPT Ads
ChatGPT Ads puts a sponsored card under ChatGPT answers for Free and Go users. Idlen puts a native ad in the IDE, the browser, and the chat apps you ship. Same moment of intent, different room.
Conversational ads in ChatGPTDetailed Comparison
| Metric | ChatGPT Ads | Idlen |
|---|---|---|
| Where the ad shows | Under a ChatGPT answer, labeled sponsored | In VS Code, Cursor, Chrome, and publisher chat apps |
| Who can see it | Free and Go. Not Plus, Pro, Business, Enterprise, or Edu. Not under 18. | Developers using the extension or a chat app that shipped the SDK |
| Targeting | Conversation context plus "context hints". Not keywords. Optional personalization from other ChatGPT chats. | The stack in the repo (React, Python, AWS) plus the context the publisher sends |
| Buying | Reach (CPM) or Clicks (CPC). Second-price auction. OpenAI suggests starting CPC at $3 to $5. | You set a budget. First test is €200 in credit. No card. |
| Welcome offer | Spend $500, get $500 in ad credit (current offer on ads.openai.com) | €200 credit after the welcome-offer form. No spend first. |
| What advertisers get from the chat | Aggregated views and clicks. Not the conversation. | The same. Prompts stay on the machine. We do not read them. |
| Does the ad change the answer | No. OpenAI keeps the ad off the model reply. | No. The ad sits next to the wait, not inside generated code. |
| Measurement | Ads Manager reports, pixel, Conversions API, UTMs | Ads Manager plus the Idlen pixel, with campaign and ad on the click |
| Best if you sell | Almost anything people compare inside ChatGPT | A tool, API, or service developers actually install |
Why Idlen over ChatGPT Ads?
ChatGPT Ads Strengths
ChatGPT Ads Limitations
Who Should Use What?
Use ChatGPT Ads if
Consumer brands, retailers, and anyone selling into a ChatGPT comparison (laptops, insurance, meal kits) where Free and Go users are enough
Use Idlen if
Developer tools, APIs, cloud, and hiring. You want the person who still has the repo open, not the person asking ChatGPT which laptop to buy.
ChatGPT Ads is a real buy if your customer lives in ChatGPT on Free or Go. Idlen is the buy if your customer lives in the editor. Same idea (intent, then a card). Different building. Plenty of teams will run both. Do not pretend one replaces the other for every product.
ChatGPT Ads vs Idlen
ChatGPT Ads is OpenAI selling a card under the answer. You buy it at ads.openai.com. The pitch is simple: people use ChatGPT to compare options, so you show up there.
That part is real. The limits are also real.
What you are buying on ChatGPT
The unit is a sponsored block under the reply. Name, favicon, title, copy, image, link. It is labeled. It is not mixed into the model's text. OpenAI is public about that.
You do not buy keywords. You write context hints on the ad group and hope the live chat is close enough. If the user left personalization on, older chats can help the system pick you. You still do not get the transcript.
Buying is Reach (CPM) or Clicks (CPC). Auction is second price, weighted for relevance. The help center tells you to start CPC around $3 to $5. Reporting is impressions, clicks, spend, CTR, average CPC or CPM, and conversions if you set up the pixel or the Conversions API. Product feeds exist if you have a catalog.
The audience filter is the one people skip. Ads run on Free and Go. They do not run on Plus, Pro, Business, Enterprise, or Edu. They do not run for under-18 accounts. A lot of people who pay for ChatGPT, including developers doing paid work, never see the ad.
OpenAI currently puts a $500-for-$500 credit on the Ads site. That is an offer, not a law of physics. Check the page before you plan a year around it.
What you are buying on Idlen
Idlen sells the same kind of wait in a different room. The model thinks in Cursor or VS Code. A native card shows. Or a publisher drops @idlen/chat-sdk in a chat they shipped, and the card sits under that reply.
Targeting is the stack in the repo, not a guessed prompt. You can ask for React without hoping someone typed "React" into ChatGPT Free.
The first test is €200. You fill the welcome-offer form, then create an Ads Manager account with the same email. No card. You do not have to spend €200 to get €200.
We do not read prompts. The extension keeps them on the machine. Chat matching uses only what the publisher chose to send.
Pick the room, not the slogan
If you sell mattresses, insurance, or a laptop, ChatGPT Ads is the closer product. The user is already asking the consumer question.
If you sell a CLI, an API, a cloud, or a job to a person who still has package.json open, buy Idlen. That person may be on ChatGPT Plus. Your ChatGPT ad never loads.
You can run both. Just do not buy ChatGPT Ads and call it "developer marketing" because a few Free users asked how to learn Python.
