A Speechify alternative that answers questions about your documents

Speechify is excellent at one thing: turning text into a clear, natural voice you can listen to on the go. But listening is one-way. If you've ever wanted to stop the audio and ask "wait, what does this part actually mean?" — that's the gap. jErVIs is a Speechify alternative that answers questions: you talk to it out loud, it explains your document, and it can quiz you on the content instead of just narrating it.

Reading aloud vs. actually talking about it

Text-to-speech and a voice conversation are two different jobs. Speechify does the first one very well — it takes a document or article and reads it to you in a smooth voice, at whatever speed you like. That's genuinely useful for getting through a long reading list while you walk, drive or do the dishes.

jErVIs is built for the second job. You upload a PDF or paste your notes, and instead of only hearing it read back, you can interrupt and ask things: 'Summarise chapter three,' 'What's the difference between these two terms,' 'Give me the key dates.' It answers out loud, in a natural voice, so the whole thing stays hands-free. It's less like an audiobook and more like having someone who's read the document sitting next to you.

Why 'answers questions' matters for revision

Passive listening is comfortable, but it's a weak way to actually remember something. The research-backed move is active recall — being asked a question and having to produce the answer from memory. That's the part a pure reader can't do for you.

jErVIs can flip your document into a quiz. Ask it to test you on your study notes and it fires questions at you, waits for your spoken answer, and tells you how you did — all out loud, so you can revise while cooking or on a commute. You're not just hearing the material go past; you're being made to retrieve it, which is where the learning sticks.

Where each one fits

Pick the tool that matches what you're trying to do. If your goal is to consume a large volume of text as audio and you love fine-grained speed and voice controls, Speechify is a strong, mature choice and worth using for that.

If your goal is to interact with a specific document — understand it, get it explained in plainer words, or be quizzed on it before an exam or meeting — that's the honest point of difference for jErVIs. It's voice-first and two-way: it reads YOUR file, then talks with you about it rather than only reading it at you.

• Choose Speechify when you mainly want polished, fast text-to-speech playback of lots of content.
• Choose jErVIs when you want to ask questions, get explanations, and be quizzed on a document hands-free.
• Both are voice-based — the difference is one-way narration vs. a back-and-forth conversation.

How jErVIs works

It runs right in your browser as a PWA — no app-store download. You sign in with Google, add it to your home screen, and talk to a glowing orb using hands-free 'Hey Jervis' mode. Speech recognition happens in the browser, with a Whisper speech-to-text fallback on the server for browsers that don't support it, so voice works across devices.

You can also make it yours: restyle the orb's colour and mood, and tune five personality sliders (analytical, playful, dry humour, brooding, warmth) so its explanations land the way you like. The free tier gives you 8 messages a day; Pro is $2.99/month or $29.99/year for more daily messages and bonus credits. A quick honesty note — the answers are helpful but not infallible, so treat it as a smart study partner, not a guarantee of grades.
