TestFlight beta · iOS 18+

Learn Spanish by texting the people who matter.

Your life in Spanish is already a text thread. BiloChat lives there — with a coach that catches the thing you were about to send.

Nobody ever stalled out because they didn't know the word for apple. They stalled because they froze mid-text to their partner's mom.

So BiloChat starts there: real threads, real people, real stakes — and a coach reading over your shoulder before you hit send.

THE BEFORE-SEND COACH

Fix it before they read it.

Type what you can, in whatever mix comes out. The coach reads the draft, corrects the grammar and tone, and hands the words back to you as something to keep.

HOW IT WORKS

A loop, not a treadmill.

Four steps that feed each other. Nothing to grind, no owl to disappoint — the thread is the homework.

01 Chat

Write to a real person — partner, suegra, primo. Or warm up against the AI partner first.

02 Save

Tap any word in your draft. It lands in the Word Bank with the sentence you used it in.

03 Practice

Nineteen drill formats built from your own words — flashcards, listening, conjugation, cloze, sentence assembly, speed match.

04 Send

Use it again for real. Real usage earns XP; 80 XP and the word is yours.

FINITE BY DESIGN

Small sets that close. Ten words and one tense at a time. You finish a set, it closes for good, and the next one opens — so there's always an end in sight, not an endless ladder.

IMESSAGE EXTENSION

It lives in the thread you already use.

You don't have to move the relationship into a language app. Open BiloChat from the app row in Messages, compose with the coach, send it as you.

No app-switching. The coach comes to the conversation instead of the other way around.

They see the effort. Your messages arrive in their language, in the thread they already read.

Translation stays on device. Ordinary translation runs through Apple's on-device engine — it never leaves your iPhone. How we handle your data.
