Lowtide vs Cora: a calmer Gmail, or one list across your tools?
Updated
Short answer: If what slips is spread across Gmail, Slack and meetings, Lowtide is the better choice: one list in your Mac’s menu bar of the replies you owe, the answers you’re waiting on and the promises you made, each with a draft, while your inbox stays as it is. Cora is the better fit if your inbox is mostly noise and you want it cleared, with a Brief twice a day.

What’s the difference between Lowtide and Cora?
Cora changes your inbox: it decides what’s important, keeps that in Gmail with a draft reply ready, and archives the rest into a Brief you read in the morning and afternoon. Lowtide leaves your inbox exactly as it is and keeps a separate list, in your Mac’s menu bar, of what you owe people, from Gmail and also from Slack and your meetings.
Which is better for following up?
Cora’s site doesn’t describe tracking emails you sent that nobody answered. Lowtide lists those under what you’re waiting on, with a follow-up drafted, and does the same for questions you asked in Slack.
How much do they cost?
Cora’s Professional plan is $20 a month billed annually for two accounts, and Unlimited is $39 a month billed annually, with a 7-day trial. Lowtide is free while it’s in early access.
Can you use both?
Yes, and they fit together: Cora clears the noise out of your inbox, and Lowtide, which reads what’s in your inbox, lists what you owe from what’s left, alongside Slack and your meetings. You’d get two drafts for some emails, so pick which one writes them.
