Is there an app for talking a topic through 1:1 with a stranger?

Yes. Otter Curiosity is built around exactly that: you post a question or a poll, and a reply to it isn't a public comment but the start of a private 1:1 conversation. Random chat apps are 1:1 as well, but they match you with no topic in common.

Will the other person know who I am?

It depends on the place. Reddit lets you use a username, but replies are public. Threads and X are usually tied to your account. On Otter Curiosity, people see your nickname and what you write, never your photo.

Is Otter Curiosity a dating app?

No. It's for talking about ideas, with no dating or matchmaking.

Where can you talk a topic through with one person?

A disclosure first: I made Otter Curiosity, so I'm biased. I've tried to be fair about what every option here is good and bad at, Otter Curiosity's own limits included.

First: what kind of conversation do you want?

"I want to talk about this" can mean two quite different things.

You want lots of reactions. You put a question out and see what people say and which view comes out on top.
You want to go deep with one person. You want to say your whole thought, and to really understand why someone else sees it differently.

The first needs an audience. The second is easier without one. So for each place below I ask two questions: who can see your reply, and what does the conversation start from?

At a glance

Place	Who sees your reply	Starts from	Best for
Reddit	Everyone	A community and a post	Hearing many views fast, niche topics
Discord	Everyone in the server or channel	A community	Ongoing chat with a group you've joined
Threads, X	Everyone	Your account and posts	Sharing takes, following people
Random chat apps	Only the other person	A random match	Talking to someone right now, about anything
Otter Curiosity	Only the other person	A question or a poll	Talking one topic through with one person
Book clubs, discussion groups	Whoever is in the room	A book or a theme	Face-to-face, over months

Reddit: every topic, and a crowd for it

Whatever you want to talk about, there's probably a subreddit for it, and the replies come fast. Voting surfaces the answers most people agree with.

The flip side is that your reply sits in front of everyone, and votes decide whether it's seen at all. A careful, unpopular reply tends to sink, and a long back-and-forth between two people gets lost in the thread.

Discord: good once you're inside a community

Discord servers can be warm, lively places, and they're great for an ongoing conversation with people who share an interest. They work best once you've found your server and know the regulars. Walking in to discuss one idea with someone new is harder.

Threads and X: built for sharing, harder for depth

Both are good for putting a view out and seeing how people react. An algorithm decides who sees what, and replies and likes are public. If reach is what you're after, that's a feature. If you want one person to really hear you, it's pressure.

Random chat apps

Their strength is that someone is there right away, and nobody sees your face. But the matching usually has nothing to do with a topic, so many chats start with "hi" and "where are you from?" and end a few lines later. Good for when you just want someone to talk to; less good for when you have a specific thought you want to work through.

Otter Curiosity: a 1:1 conversation that starts from a topic

This is the one I built, so here's plainly how it works:

You post a question or a poll, and say why you're curious.
Someone reads it and replies. That reply isn't a public comment: it's the start of a 1:1 conversation.
The two of you talk it through in a chatroom, with nobody watching.

People see your nickname and what you write, not your photo. There are no follower counts and no trending list. Messages are translated between English and Traditional Chinese automatically. Report and block are always one tap away, and posts, polls and first replies go through a content review before they appear.

Where it falls short, honestly:

The community is small, and most otters are in Taiwan, so in English a post can take a while to get its first reply.
It's an iPhone and Android app only; there's no web version.
It isn't a dating app.
It needs back-and-forth. If you want to vent without hearing the other side, it probably won't feel right.

If you'd like to know why it's built this way, I wrote about why I made Otter Curiosity.

And don't forget offline

Book clubs, philosophy cafés, a long dinner with one friend: all still excellent. Face to face you get tone and expression, which text never fully carries. The cost is fitting around times and places, and you're less likely to meet someone who thinks very differently from you.

In short

There's no best place, only the right one for the conversation you want right now. If you want an audience, go where the audience is. If you want one person to hear you out, choose somewhere replies are private and conversations start from a topic.
