How do I stop pasting Slack threads into ChatGPT to write a reply?
The short version: Let the tool that can already see the thread write the reply. Opsis writes your next line wherever you type: Slack, Gmail, Outlook, Teams, Notion, Google Docs and AI chats like Claude and ChatGPT. Press Tab to keep it. It can also draft a whole reply from a few notes, using facts from your own work: what's on your screen, the apps you connect (Gmail, Calendar, Drive, Slack, Notion, GitHub, Linear, Outlook) and your history.
The paste routine is: copy the thread or take a screenshot, open ChatGPT or Claude, explain who is who, ask for a reply, copy it back. It works, but it is slow, and the model still doesn't know what is in your calendar or tickets. Opsis skips the round trip.
How it compares.
Replying to a noisy thread, as of November 2026
| Approach | Steps | Knows the thread | Knows facts from other tools |
|---|---|---|---|
| Opsis | Type a few words or press Tab. Read. Send. | Yes, from the screen. | Yes, if you connected them. |
| Screenshot into ChatGPT or Claude | Screenshot, switch window, prompt, copy, switch back, paste. | Yes, what the screenshot shows. | No, unless you add it. |
| Paste thread text into a chat | Copy, switch, paste, prompt, copy back. | Yes, what you copied. | No, unless you add it. |
| Bot that auto-replies | None, but it posts without you. | Yes. | Depends on setup. |

Your data.
Opsis only follows the apps you share. Private windows and password managers are never recorded. When assistance is on, the text it needs is processed in the cloud with your consent, encrypted in transit and at rest, with zero data retention at our AI providers. Opsis isn't a screen recorder. You can pause, disconnect an app or delete your history whenever you like. Read the privacy policy · How Opsis handles data.
Why it is worth stopping
The paste loop adds steps to every reply. Each one carries a small risk: the screenshot misses a message, or the model writes with confidence about a fact it never had.
Keep the chat for the hard ones
A chat window is still the better place to think through a sensitive reply or a long plan. Opsis is for the replies where you already know the answer and want it written.
