Frequently Asked Questions
Is BufferMind free?
There is a free plan with every feature included — 7 hours of recording and about 20 AI uses a month — no credit card to start. Pro raises that to 35 hours of recording and about 100 AI uses a month ($9.99/month or $19.99 per 3-month term); Max removes the cap on both recording and AI ($19.99/month or $44.99 per term). A question counts as 1 AI use; review notes or a course analysis count as 3. Cancel anytime from inside the app.
What languages does it support?
BufferMind transcribes 60+ languages, detected automatically — including when a speaker switches languages mid-lecture — and translates into the language you choose. The full list is in the app's language picker.
Does it work offline?
No. Speech recognition, translation and the AI features (powered by Claude) all run in the cloud, so an active internet connection is required.
How accurate is the translation?
Accuracy depends on audio quality, accent, and subject matter. Technical vocabulary is handled by built-in domain dictionaries, and a clear microphone signal makes the biggest difference — see "Audio quality issues" below.
Can I record on my iPhone and continue on my Mac?
Yes. Sign in to the same account on iPhone, iPad, Mac, Windows, or the web — all your recordings automatically sync across devices.
Where are my recordings stored?
Audio is stored in Cloudflare R2; transcripts, translations, and notes are stored in Supabase. Everything is encrypted in transit and at rest, and only your account can access it. The Privacy Policy lists where data is processed and how long it is kept.
Can I export my transcripts and notes?
Yes. From a recording's detail page you can export the bilingual transcript and notes as a PDF through the system print dialog.
Account Management
How do I delete my account?
Open the BufferMind app → Account → Delete Account. Your recordings, transcripts, and profile are deleted right away; a small number of records are kept for a limited period as described in the Privacy Policy (for example, App Store purchase records).
If you can't access the app, email support@buffermind.com from your registered email address and we'll process the deletion within 7 business days.
I forgot my password
On the sign-in screen, tap "Forgot password?" and follow the email link. If you signed in with Google, Apple, or LINE, use the same social provider to sign in again.
Can I change my account email?
Currently not supported in-app. Email support@buffermind.com with your current and new email address to request a change.
Troubleshooting
Recording won't start
- Check the microphone permission for BufferMind: iPhone / iPad — Settings → Privacy & Security → Microphone · Mac — System Settings → Privacy & Security → Microphone (and Screen Recording, for system audio) · Windows — Settings → Privacy → Microphone · Browser — allow the microphone when prompted, or in the site's permissions
- Ensure you have an active internet connection
- Restart the app if the issue persists
Translation is delayed or missing
- Check your internet connection (a stable connection is required for live transcription)
- Technical terminology may take slightly longer to translate than simple phrases
- If delays persist, please contact us with the approximate time of the session
Audio quality issues
- Position your device closer to the speaker when possible
- Reduce background noise (close windows, use a quiet room)
- For lectures, external microphones connected via USB-C or Bluetooth can improve quality
