How aac to srt works
Upload your AAC
Drop in the AAC file – we decode and prepare the audio automatically.
Get timestamped text
AI transcribes the speech into cues with precise start and end times in minutes.
Export as SRT
Download a ready-to-use .srt (or VTT) subtitle file – edit any line first if you like.
AAC is the audio you get out of M4A files, Apple recordings, and most video exports – but to caption something you need an SRT, with each line timed to the second. Pepys does that in one pass: upload the AAC and download a clean .srt you can drop straight into a video editor or player.
Every cue is timestamped automatically, so you skip the tedium of typing lines and aligning timecodes by hand. Your first 60 minutes are free, you pay only for what you transcribe, credits never expire, and we never train on your audio.
Clean paragraphs. No more um's and ah's.
The left is what Pepys hands back – logical paragraphs with the filler stripped out, punctuated and readable. The right is the raw, one-line-per-segment dump most transcribers leave you with.
um so yeah everyone keeps telling you to like lead with your best line right but uh honestly if you give away the whole answer in the first second you know there's basically no reason for anyone to keep watching so the hook isn't kind of the smartest thing you say it's like a loop you open that they need to close and um that's the part that actually keeps people around
