People look past Dim0 for a few documented reasons. It runs in the browser only, with no native apps, so there is no offline or desktop use. The site says it is free only during early access and its pricing page returns a 404, which leaves future cost unknown. Phone use is read-friendly only, and self-hosting needs your own model keys, Postgres and a vector database. The cloud version has no customer-held keys or zero-knowledge encryption, so strict confidentiality means self-hosting.
Notion AI is the closer match if you want notes and AI in one workspace: its Plus plan is $12 per member per month ($10 when billed yearly), and AI is only a limited trial on that tier. There is a free Notion tier too. Gemini Notebook (formerly NotebookLM) takes a different angle, answering questions and building summaries, audio and slides from your own sources; it has a free tier, but a starting price is not stated in our verified data. Neither is an open-source infinite canvas with board-aware agents, which is what Dim0 offers.

Full AI needs Business or Enterprise, and even there a rolling six-hour and monthly usage allowance applies; premium models, Custom Agents and Workers consume separately purchased Notion credits.
Free tier has standard usage limits and 50 sources per notebook; higher limits need a Google AI Plus, Pro or Ultra plan, which Google says are only available in specific regions.
Both listed alternatives have a free tier: Notion AI and Gemini Notebook (formerly NotebookLM). Dim0 itself is described as free during early access, with no pricing page.
Why would someone leave Dim0?
Documented reasons are browser-only access, uncertain pricing after early access, read-friendly-only phone use, and the setup work of self-hosting.
