Krater AI review

Krater AI is a subscription-based workspace that combines AI models, content tools, research and automation. Its site lists access to 500+ models, including ChatGPT, Claude and Gemini, with an Auto Router option. The workspace also covers creating text, code, images, video, audio, slides, documents and websites.

Krater says its AI agent can plan a goal, research, browse the web and run tools. You can connect apps such as Gmail, Slack, Notion and GitHub; the homepage lists 1,400+ connections. Other features include scheduled tasks, project memory and research across PDFs, URLs, videos, web sources and your own files.

The listed plans start at $20 per month for Pro, with no free plan listed. Annual billing is $200 upfront for Pro, equivalent to $16.67 per month. Ultra is listed at $49 monthly, Max at $119, and Enterprise has custom pricing.

Krater’s main appeal is breadth: one subscription puts model access, creative tools, source research and an agent in the same workspace. That can be useful if your team wants to move between drafting, analyzing published material and producing different formats without maintaining a separate tool for every step. The pricing page lists 500+ models, while the homepage lists 1,400+ app connections.

The plans also spell out several useful capacity differences:

• Pro: 1,500 credits per month, a 150k context window, 25 GB storage and three scheduled tasks for $20 monthly, or $200 billed annually.
• Ultra: 4,000 credits per month, a 400k context window, 100 GB storage, 20 scheduled tasks and the ability to publish two websites. It costs $49 monthly, or $490 billed annually.
• Max: a 1M context window, 250 GB storage, 50 scheduled tasks and publishing for five websites, at $119 monthly or $1,190 billed annually.

Those larger context windows and higher task limits give buyers concrete reasons to move up a tier. Ultra is also described as including API access, which may matter to higher-volume creators.

The key trade-off is that a large tool catalog does not mean unlimited use. Pro includes 1,500 credits a month and three scheduled tasks; Ultra raises those caps to 4,000 credits and 20 tasks. Max lists 50 scheduled tasks, but its monthly credit allowance is not published. That makes it harder to estimate whether the top plan fits a workload before subscribing.

The pricing page lists credit top-ups for Ultra and Max, but does not publish their price. Buyers therefore cannot calculate the cost of going over the included allowance from the published pricing details. Enterprise pricing is also custom, though the plan lists unlimited team seats, SSO and SAML, SCIM provisioning and a dedicated account manager.

There is no free plan listed, and the published pricing details do not state whether a free trial is available. Annual billing lowers the stated monthly equivalent, but requires $200, $490 or $1,190 upfront for Pro, Ultra or Max. We would check credit usage and top-up costs before treating the headline plan price as the full cost.

Krater AI has no free plan. Pro is $20 per month, or $200 upfront annually (about $16.67 per month), and includes 1,500 credits monthly, 500+ models, 25 GB storage and three scheduled tasks. Ultra is $49 monthly or $490 upfront annually (about $40.83 monthly): that is a $29 monthly jump from Pro, for 4,000 credits, 100 GB storage, 20 scheduled tasks and API access. Max costs $119 monthly or $1,190 upfront annually (about $99.17 monthly), another $70 per month above Ultra. It raises storage to 250 GB and scheduled tasks to 50, but its monthly credit amount is not published. Enterprise pricing is custom. The listed annual prices are averages based on upfront billing, not monthly payments. Credit top-ups are listed for Ultra and Max, but their prices are not published, making extra usage hard to budget. A free trial is not specified on the vendor's site.

Treat Krater as a new workspace, not a documented one-click migration. The published information does not specify import tools, data export formats or a way to transfer project memory, prompts, schedules or files from another service. Before moving, check what you can export from your current tools and plan to reconnect services such as Gmail, Slack, Notion or GitHub. Krater lists 1,400+ app connections, but that does not confirm that your existing settings or workflows will carry over. Scheduled tasks and connected-app workflows may need to be recreated; the plan limits are three on Pro, 20 on Ultra and 50 on Max. The published sources include no Reddit posts or comments, so we can't substantiate claims about why users leave or how difficult they find leaving. Ask Krater about data export, project-memory portability and account deletion before you put important work there.
