Medusa: Synapse

Medusa: Synapse turns the sentences YOU actually use into native-level English — and makes them stick.

Most language apps teach someone else's sentences. Medusa starts with yours: type a sentence in Turkish or French, and the AI rewrites it as two native-level English variants — one natural, one polished — then explains what makes it native: the collocations, phrasal verbs and connectors real professionals use.

HOW IT WORKS

1. Capture — type the sentence you wish you could say in English.
2. Upgrade — AI returns two native-level variants, broken into natural word chunks.
3. Play — rebuild each sentence from shuffled chunks in a drag-and-drop puzzle.
4. Retain — a spaced-repetition engine schedules smart reviews so it sticks for good.
