ChatGPT Spaces Launches, Drawing Notion Comparisons
At DevDay, OpenAI launched ChatGPT Spaces, a space where humans, teammates, and agents collaborate together—on tasks like building slide decks—bringing page generation, organization, and presentation into ChatGPT. Several bloggers tested it right away and shared their takes, with discussion centered on the product's form factor and strategic intent.
Confirmed
- Spaces is now live, positioned as a collaboration/workspace capability, supporting humans, teammates, and agents working together, such as co-creating slides
- Blogger kimmonismus tested it and said the interface feels "very futuristic," but looks like Notion and is a bit information-overloaded—worth trying hands-on
- Blogger cneuralnetwork initially compared it to "Perplexity's report feature but with more stuff crammed in," then revised their view after trying it, saying it's closer to Notion's collaborative workspace form
- LinusEkenstam said it has "Notion killer" potential by folding workspace/notes capabilities into ChatGPT, and speculated this might be an early form of OpenAI building a super app
Not yet confirmed
- While discussing Spaces, LinusEkenstam posted a screenshot mentioning what appears to be "GPT-6.1 Sol"—currently just leaked information with no official confirmation
- LinusEkenstam also raised a question: as OpenAI's product line balloons, can the company keep investing enough in each product, or will everything run on "swarms of agents" in the future? That remains unanswered
Why it matters
- Spaces builds collaboration and document/workspace capabilities directly into ChatGPT, squarely targeting Notion and other productivity tools; kimmonismus sees it as OpenAI's frontal assault on Claude
- If the "super app" speculation holds, OpenAI would expand from a conversational assistant into a comprehensive productivity platform, potentially reshaping the office collaboration landscape
