What you get: a Hindi class, in English, in three steps

An example with a 40-minute polity lecture recorded on a phone.

1 · Record or upload

Upload the MP3 from your phone, or press record in the browser. Free files can be up to 100 minutes.

2 · Get it in English

You get the Hindi-English transcript as it was spoken, then tap Translate → English. Both stay in one note, with a summary.

3 · Ask it questions (Pro)

Example question: “What did sir say about Article 21, and in which class?” Or: “Make 20 practice questions.”

Example

Spoken: “Maneka Gandhi case ke baad Supreme Court ne kaha ki procedure fair, just aur reasonable hona chahiye.”

English: “After the Maneka Gandhi case, the Supreme Court said the procedure must be fair, just and reasonable.”

Asked (Pro): “What did sir say about Article 21, and in which class?” → Answer: “Procedure must be fair, just and reasonable (Maneka Gandhi, 1978); privacy is part of Article 21 (Puttaswamy, 2017). Source: Polity — Lecture 3, 14 Oct.”

Why the English reads like a person wrote it

The whole recording first. hearlog writes out everything that was said, then translates the full text — so a sentence keeps the context of the lecture or call around it.
Original and English side by side. Quote the exact words, check a name, or translate the same note into another language later.
A summary with every note. A 40-minute class becomes a page of notes you can revise from. Made by USD Vision AI LLP, powered by Google Gemini.

Translating a lot? What Pro adds

Ask across all your recordings — one question over a whole folder of lectures, calls or interviews, with the source named.
2-hour files in one go (free: 100 minutes) and Unlimited (fair use) transcription (free: 300 minutes a month).
10 files at once — a week of recordings, each turned into its own note.

Pro is ₹2,990/year or ₹299/month ($6.99 or $49 outside India).
