The 39 questions
Each asked once on ChatGPT, Gemini, Google AI Mode, Perplexity and Claude on 19 Oct 2026, under the buyer scenario it comes from. Google AI Overviews were asked the search keywords listed with them above instead.
Thousands of unread Gmail, cleared fast and for free
- Problem firstI have over 11,000 unread emails in Gmail and I'm embarrassed to even look at the number. How do I get rid of all of them without accidentally losing something important from a customer?
- How toWhat's the fastest way to clear 8,000 unread emails in Gmail? I know the search trick with is:unread and older_than, but select all only grabs 50 at a time and I'd rather have the newsletters sorted out from real people than nuke everything.
- Best toolIs there a free tool that cleans up a Gmail inbox for me? I want something that archives old promotions and notifications instead of deleting them, and I need to be able to undo it if it gets something wrong.
- Asks for AICan an AI agent go through my Gmail, figure out which of my 6,000 unread emails are junk and which are people actually waiting on me, and clear the junk? I run a SaaS company and don't have time to triage by hand.
- Names an AI clientI connected ChatGPT to my Gmail and asked it to clean up my inbox, but all it did was summarize the last few emails. Is there any way to actually bulk archive thousands of old unread emails with AI?
Safe bulk unsubscribe and archive, picking a cleaner I can trust
- Best toolWhat's the best email cleaner app that's actually safe to give access to my Gmail? I want to unsubscribe from hundreds of newsletters and clear out old promotions, but I don't want something that sells my data.
- ComparisonClean Email vs SaneBox vs Leave Me Alone for cleaning up a really messy Gmail. I have around 14,000 emails from newsletters and promos and I want to bulk unsubscribe and archive the old stuff. What are the real tradeoffs on price and privacy?
- Problem firstI keep unsubscribing from emails and a week later they come back from a slightly different sender. There are thousands of promotional emails piling up. What do normal people do about this?
- How toHow do I archive all the promotions in Gmail at once, and is it safe? Will I lose something I need, and can I get it back if I archive the wrong thing?
- ComparisonI used Unroll.me years ago and then found out they sold user data. What's a trustworthy alternative now for unsubscribing and sorting newsletters in bulk? Ideally one that doesn't delete anything.
AI that drafts replies in my own voice, never sends on its own
- Names an AI clientI paste emails into ChatGPT to draft replies but it never sounds like me and the copy-paste loop kills any time I save. Is there a way to have an AI read my inbox and write the replies in my own style?
- Asks for AIIs there an AI that can write my email replies in my own tone, but doesn't send anything until I approve it? I'm a consultant and I answer the same kinds of emails all day.
- How toHow would I set up Claude or any LLM to learn my writing style from my sent folder and pre-draft replies in Gmail threads? I'd want them saved as drafts, never auto-sent, ideally running in the background.
- ComparisonGmail's Help me write and smart reply feel too generic. Are there better AI tools that actually learn how I write and handle replies across my whole inbox? Happy to pay around $50 a month.
- Best toolbest AI email reply tool for someone who gets 100 emails a day and hates typing. needs to work with gmail
Stop dropping follow-ups, both ways
- Problem firstI keep dropping the ball on emails. Someone asks me something, I mean to reply later, and then it's buried three days down. And when I'm waiting on someone else I forget to chase them. How do people not let this happen?
- Best toolWhat tool will remind me or automatically nudge people who haven't replied to my emails in Gmail? Boomerang-style but smarter, I'd like it to draft the follow-up for me too.
- How toHow do I set up automatic follow-up reminders in Gmail for emails that didn't get a response? I send maybe 20 important emails a week and half of them never get answered.
- Asks for AICan I get an AI to watch my inbox and tell me every morning who is still waiting on a reply from me, oldest first, and who went quiet after I emailed them? I run a small agency and lost two deals last month to slow follow-ups.
- No AIwhat's a good system for following up on emails that got no response? i'm a freelance consultant and i send a lot of proposals
Replace the VA or executive assistant for email, and run it from my phone
- No AII'm paying a virtual assistant about $800 a month and a big chunk of that is just sorting my inbox and drafting replies. Is there a cheaper way to get the same email help? I'd still want to approve anything that gets sent.
- Asks for AICan an AI assistant realistically replace an executive assistant for email? I get 200 emails a day, travel constantly, and I want something that flags the urgent ones and drafts replies I can approve from my phone.
- Best toolWhat's the best AI executive assistant for managing email that I can talk to over iMessage or text? I'm on my phone all day and I hate opening Gmail.
- Problem firstI'm about to hire an executive assistant mostly because I can't keep up with email. But I'm not sure I want to give someone full access to my inbox or pay a salary for it. What are my other options?
- Names an AI clientHow could I build something that texts me over iMessage when something important lands in my Gmail and lets me reply 'send' to approve a drafted reply? Is there something that already does this, or do I need to wire it up with n8n and an LLM?
Shopping for an AI email assistant: Fyxer, Superhuman, Shortwave and the rest
- ComparisonFyxer vs Superhuman for a founder who gets 150 emails a day. Which one actually saves time, and is there anything better than both? I use Gmail.
- ComparisonLooking for a Fyxer AI alternative. I tried it and it mostly just labels my emails and writes okay drafts, but I want something that also chases people who haven't replied. Any recommendations?
- Best toolwhat is the best AI email assistant in 2026 for Gmail or Outlook? looking for one that drafts replies and sorts my inbox, under $50 a month
- ComparisonGemini in Gmail vs a dedicated AI email assistant like Fyxer or Shortwave. Is Google's built-in AI good enough, or do I need a separate product? I mostly care about drafting replies, summarizing long threads and not letting things slip.
Outlook and Microsoft 365 users: clean up the mailbox, then get an AI assistant
- Problem firstMy Outlook has about 30,000 emails and I can't find anything. I just want to clear out the junk and old stuff without deleting anything I might need for work. Where do I even start?
- How toHow do I mass clean up my Outlook inbox? I want to archive everything older than six months, unsubscribe from the newsletters I never read, and set it up so it stays tidy.
- Best toolBest AI email assistant for Outlook? I'm on Microsoft 365 and Copilot costs extra. I want something that sorts my inbox and drafts replies.
- ComparisonIs Copilot in Outlook worth paying extra for, or are there better AI tools for email triage and replies? My company uses Microsoft 365 Business.
- Asks for AIIs there an AI that can organize my Outlook inbox and tell me which emails I actually need to reply to? I'm not technical.
Inbox zero for founders, and staying there without a daily triage session
- Problem firstEvery time I get my inbox to zero it's back to 2,000 unread within a month. I'm a founder with a small team and email is eating two hours of my day. How do I actually keep it under control long term?
- How toHow do founders manage email without spending half the day in it? I'm looking for an actual setup: what gets auto-sorted, what I reply to, what I ignore, and where AI fits in.
- Asks for AII want an AI agent to run my email triage: sort everything, only surface what needs me, draft replies for review and give me a summary a couple of times a day. What's the best way to set that up on Gmail? Willing to pay for something that just works.
- Names an AI clientHas anyone got Claude or ChatGPT actually running their inbox day to day, not just one-off summaries? I want triage, drafts and follow-ups happening in the background while I work. What setup works?
- Best toolWhat do the most productive CEOs use to get to inbox zero and stay there? Superhuman? Something with AI? I'd rather automate it than build habits.
How these numbers are counted
- Share
- Share of an engine's answers in this category that recommend the brand; range is the 95% Wilson interval.
- Left out
- Questions that named one of our products, and a few that named one of our data suppliers; AI assistants and platforms (Gmail, Slack, LinkedIn and similar) are not counted as recommendations.
- Google AI Overviews
