Fonna is back in the workshop.
We found persistent technical issues in the way Fonna listens to a track — problems that were shaping the feedback in ways we can't stand behind. Rather than keep shipping reports we don't trust, we've taken uploads offline until they're fixed.
Fonna exists to give producers something honest. A report that repeats itself, or hears the same weakness in every track regardless of what's actually there, isn't that. So we're rebuilding the parts that need rebuilding.
No tracks are being analysed, and the rest of the site is offline. Your past reports are still stored — email us and we'll send them to you.
What we found
The audio sampling and prompt layers were producing findings that repeated across unrelated tracks. The output looked confident. It wasn't consistently earned.
What we're doing
Rewriting how Fonna samples a track so it hears transitions rather than isolated windows, and rebuilding the analysis prompts from the ground up.
Where that leaves you
All accounts have been refunded where a purchase applied.
Sign-in is offline, so to get a copy of a report you've already received, email us and we'll send it. You can also close your account if you wish.
On being straight about it
We could have left the site up and quietly patched things behind the scenes. Producers upload unfinished work to Fonna and take the notes seriously, and that only works if the notes are worth taking seriously. When they aren't, the right move is to say so and stop.
If you'd like a note when analysis is back on, or you want to tell us what the reports got wrong for your music, get in touch — that feedback is going directly into the rebuild.
The wider picture
Fonna has always been one person's project: an attempt to build something that would help musicians work more creatively — a set of ears that tells you what needs attention without telling you what to write.
The ground has moved since then. The major AI labs have advanced quickly, and general-purpose models now do a reasonable share of what Fonna set out to do, improving on a schedule no one-person project can match.
So the work continues, with a clear eye on whether it should. If the rebuild produces something meaningfully better than handing your track to a general model, Fonna comes back. If this page is still the whole of the site, assume the case hasn't been made.
