Opsis compared.

Opsis vs Superhuman Go

Superhuman Go is the AI assistant from Superhuman, the company formerly called Grammarly. It launched in October 2025 as a browser extension and now runs on Mac, Windows and mobile. It reads what's on your screen, offers inline suggestions, and runs agents for jobs like scheduling and proofreading. App connectors such as Gmail, Calendar, Outlook and Slack start on the paid Pro plan, with tools like Jira, Linear and Asana on Business. The free plan has limited chat and limited inline suggestions.

The biggest difference is memory. Go works from what's on screen now and the apps you've connected. It doesn't keep a history of your own work. Opsis does: every session in the apps you share gets a plain name and a short summary, so weeks later the brief, the thread and the decision are still there.

The second difference is the job. Go is an assistant you hand tasks to. Opsis is built to assist: it waits for the moment when what you're writing contradicts something you read, agreed or promised, then shows one quiet cue with the source and when it was written. There are no notifications, badges or streaks, and nothing goes into your work until you click.

Choose Opsis if

• You want an assistant that remembers your own work across weeks, not only what's on screen now.
• You want help that finds you at the right moment, instead of tasks you have to delegate.
• You want to see the exact source behind a suggestion before you use it.

Choose Superhuman Go if

• You want agents that carry out multi-step tasks, and you're happy to pay for connectors.
• You want the same assistant on your phone.
• Your team already uses Superhuman or Grammarly.

Opsis vs Rewind

Rewind was a Mac app that recorded your screen and audio so you could search anything you had seen or heard. Its maker, Limitless, was acquired by Meta in December 2025, and the Rewind app stopped capturing on 19 December 2025. If you relied on it, you need a replacement.

Opsis is a different kind of tool. Instead of a replay of your screen, it keeps a named account of your work sessions, in the apps you choose to share. Then it uses that account while you work: a small cue when something you're writing doesn't match what you read or agreed, and a draft of the next step you can insert with one click. And it runs on Windows as well as Mac.

Choose Opsis if

• You want help in the moment, not only search after the fact.
• You work on Windows, or on both Mac and Windows.
• You'd rather Opsis follow a few chosen apps than record everything.

Opsis vs Microsoft Recall

Recall is a Windows feature on Copilot+ PCs. It saves regular snapshots of your screen, keeps them on your device and lets you search them in plain language. It's a strong option if you have a Copilot+ PC and want your history to stay entirely on that machine.

Opsis works on any recent Mac or 64-bit Windows PC, not only Copilot+ hardware. It focuses on the work rather than the pixels: sessions with plain names and summaries, sources you can open, and help that arrives inside the app you're already using. When assistance is on, content from the apps you share is processed securely in the cloud: encrypted in transit and at rest, with strict controls over your data, so you choose what's shared and can pause or delete it any time. If everything must stay on-device, Recall is the closer fit.

Choose Opsis if

• You use a Mac, or a Windows PC that isn't a Copilot+ PC.
• You want suggestions and drafts, not only a searchable timeline.
• You want every answer to show exactly where it came from.

Opsis vs ChatGPT, Copilot and Claude

Chat assistants are excellent at answering questions and writing drafts. But they start from what you tell them. You paste the brief, explain the project and remind them what was decided, and they only know about the apps you've connected or the chats you've had.

Opsis was there when the work happened, so it already knows the brief, the thread and the decision. You can still ask it anything, over any app, with a keyboard shortcut: tap Option and Command on Mac, or Ctrl and the Windows key on Windows. Many people use both: a chat assistant for open-ended thinking, and Opsis for the work already in motion.

Choose Opsis if

• You spend time re-explaining context to an AI.
• You want help to show up in the app you're in, without switching to a chat window.
• You need to check where an answer came from before you use it.

Opsis vs time trackers

Time trackers such as RescueTime log which apps and sites you used and for how long. They're good at answering “where did my week go?”. They don't know what the work was about, and they can't help you finish it.

Opsis names each session by what you were actually doing, like “Checking MECH 310 tensile results”, and keeps the reasoning behind it searchable. There are no timers, streaks or productivity scores. The point is to pick up the thread, not to keep score.

When Opsis isn't the right fit

• You need every byte to stay on your device. Opsis processes shared content in the cloud, encrypted in transit and at rest, with strict user data controls.
• You want a full video or audio recording of your day. Opsis doesn't make one.
• You work on Linux, iPad or a phone. Opsis is for Mac and Windows today.
