The Slowletter approach
HelloTalk lets you search for language partners. Slowletter routes a letter using profile preferences and recipient availability, without a public directory.
A Slowletter recipient can accept or pass on an introduction. Acceptance opens chat; sending does not guarantee a reply.
HelloTalk offers free language exchange and optional VIP. Slowletter is free to join; sends use earned letter credits and chat does not.
A first letter gives you room to introduce your interests and ask a question. You and the recipient choose how much time to give the exchange.
Letter-first does not mean fully anonymous. Recipients can see sender details before accepting, and can use blocking and reporting tools.
HelloTalk includes translations, corrections and live practice. Slowletter chat supports text and recorded voice messages; it does not offer the same language-learning toolkit.
