An AI agent beside any Mac app. Sider Omni sidebar sees what's on your screen and acts on it directly, right where you're working. Watch the result, ask for the next change. Nothing to copy, nothing to upload. Built on GPT-6 Astra, and it can run on your existing ChatGPT or Codex credits.
We built Sider Omni so your agent can join the work you're already doing, with the context to understand it and the ability to act on it.
With a table open in Numbers, ask: “Create a bar chart of sales by region from this table.” 📊
Sider Omni reads the table already on screen and builds the chart in Numbers. As you inspect it, keep refining: “Now show return rates by region in a separate chart.” 🔁
You can see the source data and each change in the same workspace, then ask for the next step without exporting data or starting over.
You can also choose from supported models, including GPT-6 Astra, and pick a companion icon that follows you across your apps. ✨
We'd love to hear what you'd use Sider Omni for. 💬
Not having to export the data before asking for the chart is such a minor but actual save of time.
As a person who is juggling Pages, Numbers and the Web in a single day, I have been wasting my time by switching from one window to another to ask the AI something. The agent which will be right beside me, which will read what is there in the document and then perform the edit is what I have been dreaming of.
As an avid user of client emails via Mail, my one bad practice is to retype the response three times. It will save me a few minutes if Sider Omni could read the entire email and type right from there. Does it support attachment as well or just visible text?
I wonder how it works in applications that have custom UIs, for example, Figma or Logic Pro. Does it depend on the accessibility labels in macOS or does it use mostly screen shots?
The Numbers chart example made sense to me. I spend half my time shifting information between applications so having a chart improved through asking what comes next seems very appealing.
Congratulations on the launch! Having the bot by the side of the application rather than in another separate chat window is the right approach in my opinion.
I liked the fact that the agent is positioned right next to the app, rather than appearing as a separate window. This small difference can make using AI during daily tasks feel much more natural and seamless.
The sidebar approach is simple, but I can see it becoming surprisingly useful once it becomes part of your daily workflow.
I like that the assistant stays close to the context instead of forcing you to jump into a completely separate app.
I really like the idea of keeping relevant information within the app instead of copying everything into an AI chat. This can make repetitive tasks feel much more fluid.
Congrats on the launch , It operates offline or in low band -width conditions?
Love that it acts right on your screen without any copy paste, keeping you in flow instead of pulling you into yet another chat window.
@rick_fan This could make computer-use agents way more practical for everyday work.
Congrats, #3 is well earned. One question from someone who ships an MCP server: can the sidebar talk to outside MCP servers, or only its own built-in tools? Use case is simple, I'm in Keynote or PowerPoint, I ask the sidebar for a deck, and it hands the brief to my tool and drops the file back in the app I'm already in. If MCP is on the roadmap I'd happily be a test case.
@rick_fan This looks really interesting! The idea of having an AI agent work directly inside different apps is pretty cool. I’ve been exploring different AI workflows lately, so this definitely caught my attention. Congrats on the launch! 🙌
Really nice. Is it safe to use :) Also, do i need a local LLM to run this?
Does it automatically choose between ChatGPT and Codex depending on the task?
