Runs offline · your music stays on your machine
SessionIQ makes the whole operation make sense. Drop in audio, MIDI and session notes and it analyzes them, organizes them into albums and songs, and answers questions about your work with citations to the exact files it used — not another confident AI guess.
The problem
Every project, every bounce, every version in one organized place — with search across the whole catalog and files that move on disk when you rename a project.
Tempo, key, loudness and length for every track, a readiness checklist per song, and a plain answer to the question that eats the end of every session.
Mark a track as your reference and every mix is measured against it — signed differences in loudness, tone and length, so "it sounds quieter" becomes a number.
Session notes, a decision log, and preferences that persist. Record what you chose and it comes back later, quoted, with the file it came from.
Your library, measured
Tempo, key with major or minor, peak and RMS level, integrated loudness to the broadcast standard, spectral brightness, beat positions, and for MIDI the notes, pitch range and instruments. All of it computed locally, on your machine.
| File | Project | BPM | Key | Loudness | Length | Status |
|---|---|---|---|---|---|---|
| midnight_drive.wav | Neon Horizon / Midnight Drive | 117 | E | −18.3 | 8.0s | In Progress |
| afterglow.wav | Neon Horizon / Afterglow | 117 | E | −18.4 | 8.0s | Idea |
| afterglow_master.wav | Neon Horizon / Afterglow | 117 | E | −18.4 | 8.0s | Ready |
| lofi_sketch.wav | Lo-Fi Study | 76 | C | −18.9 | 7.0s | Idea |
| cue_draft.wav | Client Cue 03 | 99 | A | −19.9 | 6.0s | Needs Work |

Mix vs reference
Mark any track as your reference and every mix in the project is measured against it — signed differences you can act on, rather than a feeling you argue about at 2am.

Ask it anything
Ask across one song or the entire catalog. Follow-ups work — “what about its key?” — and every answer arrives with the files it came from, so you can check it.
Counts, comparisons and superlatives are computed from the real metadata rather than guessed at, which is why "which track is the loudest" gets an exact answer instead of a list of likely candidates.
How it is measuredWhich track is the loudest?
Client Cue 03/reference.wav — integrated loudness −15.5 LUFS, the highest in the library. The quietest is afterglow_reference.wav at −25.0.
Which tracks are the fastest?
Four tracks tie at 117.5 BPM: midnight_drive.wav, afterglow.wav, afterglow_master.wav and afterglow_reference.wav. The slowest is lofi_sketch.wav at 76 BPM.
Answers shown are the computed result over the generated demo library. Every number is checked against the cited files before an answer is shown; one that fails is withheld.
Screens
Insights
Projects ranked by how close they are to finished, with the stalled ones surfaced instead of buried. Search finds files by what they sound like rather than what they are called, and the similarity engine shows you why two tracks were paired — tempo, brightness, loudness, length and key, broken out separately.
Studio
A fingerprint built from your own catalog rather than typed in — the tempo you actually work at, the keys you keep returning to, how loud your mixes land. Your preferences come back on the next session, and the timeline is a history of what entered the studio and when.
Under the hood
Questions run through five stages, and the results below come from a labeled evaluation in the repository rather than from a demo someone picked to look good. The harness is checked in, so the numbers can be reproduced — including the ones that are not flattering.
Audio, MIDI, notes, artwork
Tempo, key, loudness, brightness
Lexical, metadata, optional vectors
Grounded, tool calls for exact counts
Citations and numbers checked
The running system, not a diagram — each stage reports whether it is active.
Stated plainly: these come from one synthetic corpus of seventeen generated files and thirty hand-written questions. That is enough to compare retrieval configurations and far too small to be a benchmark. The evaluation does not score the wording of generated answers, and it does not measure hallucination. Both limits, and every case retrieval gets wrong, are written down in the methodology.
Methodology and limitsGetting it
SessionIQ is software you install rather than a service you sign up for. No account, no upload limit, no telemetry, and nothing sent anywhere. Unreleased music stays unreleased.
One command starts it, with a demo library already built in so you can look around before pointing it at your own files. Semantic search and voice transcription are optional local add-ons, and the assistant works with no model configured at all.
$ docker run --rm -p 8080:8000 sessioniq
Your library http://localhost:8080
Demo songs 17 files, 5 projects
Sends anywhere nothingWhat you need
Docker, if you want the one-command route. Prefer running it from source? Python 3.11+ and Node 22.18+ — the README walks through it, including optional local Ollama, ChromaDB and Whisper.
