6 Slowly alternatives compared (2026)
People leave Slowly for one of three reasons: the language gap, wanting more than friendship, or replies drying up. Different reasons, different answers. Here are six apps sorted by reason. Lettie is ours — read that part accordingly.

1. If language was the wall → Lettie, HelloTalk, Ablo
The most common complaint about Slowly is translation: copy the letter out to a translator, paste it back, repeat for every letter.
- Lettie puts the translate button inside the letter — 28 languages, original next to the translation, free. The slow, distance-based delivery is the same idea as Slowly.
- HelloTalk is chat, but sentence-level corrections and translation make it the most efficient tool if learning is the goal. No letter rhythm, though.
- Ablo auto-translates every message. Good for casually talking to people in many countries; don't expect depth.
2. If you want more than friendship → Lettie
Slowly deliberately has no dating layer. That's a plus for some and a gap for others. Lettie is built around meeting someone through letters: you choose who you'd like to meet and get a few matching cards a day, but there are no photos and no swiping. It's for people who found "photo first" dating apps uncomfortable.
3. If you want the biggest crowd → InterPals, Penpal World
- InterPals has been the largest pen-pal community since the 2000s. If you need someone in a specific country or city tonight, it's the fastest. The usual downsides: web-first UI, people asking for WhatsApp in the first message, spam accounts.
- Penpal World is simple profile-based matching that's been around forever. Fine if you can live with ads and a dated design.
4. If speaking practice is the point → Tandem
Tandem is strongest at voice and video calls. It's the opposite end from letters, but if "language exchange" was why you used Slowly, this may fit better.
5. If you're leaving because replies died
One note, because this follows you to the next app: replies die mostly because the first letter is all introduction and no question. Whatever app you use, end the first letter with one question that's easy to answer. Lettie's Discover softens this a little — you read what someone wrote before you reply, so there's already something to answer.
Summary
- Translation is the point → Lettie (letters) or HelloTalk (chat)
- You want the door open to meeting someone → Lettie
- Numbers matter most → InterPals
- Speaking practice → Tandem
- You like slow letters and share a language → keep Slowly
