Songwriter's
Toolkit
The whole songwriting tab-jungle, collapsed into one offline app. Find the rhyme in your language. Write the line. Drop a marker on the chorus. Hit record while the beat plays. Stack takes. Iterate. No accounts. No subscriptions. Nothing leaves your phone.
What's inside
Two tools that finally talk to each other.
Rhyme Engine
A real linguistic engine, not a spell-check shortcut.
Phonetic-aware matching, vowel / consonant / full modes, syllable control, strict-to-loose equivalence classes. Sub-millisecond search across hundreds of thousands of words, fully on-device.
Songwriter's Notepad
A lyric editor that knows where you are in the song.
Your lyrics, mapped to your song's timeline. Drop markers for verse, chorus, bridge. Record scratch vocals over the beat. Stack takes. Iterate.
Rhyme Engine
Built for the way songwriters actually rhyme.
Turkish first. Eight languages by launch.
Turkish is the reference language; Spanish, Italian, Finnish, Indonesian, Swahili, Esperanto and Portuguese ship in the same release. English and French follow in the first update via pronunciation dictionaries.
Sound, not spelling
For phonetic-spelling languages, vowel-pattern matching just works. For English and French, the engine reads from a real pronunciation dictionary (CMUdict-class) — fire pulls higher, desire, liar.
Vowel · consonant · full
Three match modes per query — perfect rhymes, assonance, consonance — switchable in one tap.
Drag-to-select tail
Two handles on the input word: rhyme on the last syllable, the last two, the whole word, anything in between.
Syllable slider · strict ↔ loose
Range −4 to +4 syllables off the baseline. A toggle for strict vs. loose, with per-language equivalence classes (Turkish i ↔ ı, o ↔ ö, u ↔ ü, etc.).
Sub-millisecond, fully offline
Reverse-suffix binary search across pre-indexed dictionaries. No spinner, no network, no leaked lyrics.
Songwriter's Notepad
A lyric editor that knows where you are in the song.
Rich text lyrics
Bold, italic, color, per-word font size. Format the way the line should read.
Beat player, built in
Load a local audio file or paste a YouTube URL. Play, pause, seek — synced to your lyrics.
Timeline + draggable markers
The page maps to your track's duration. Drop labeled, color-coded markers for verse, chorus, bridge.
Voice recording, multi-track
Hit record. The song plays while the mic captures your take. Stack takes — they all play back in sync, like a mini DAW.
Rhyme highlighting
Toggle on — every rhyme in your lyrics lights up by group, up to ten colors, updating as you type.
Instant rhyme replacement
Select a word, tap rhyme — pick from the dictionary and the line updates instantly.
Plus auto-save every 10 seconds, multiple sessions you switch between in a tap, and a scale slider for zooming into the verse you're working on.
Why Toolkit
One app instead of four browser tabs.
Songwriters today juggle a rhyme website, a notes app, a music player, and a voice recorder. Toolkit puts all of that in one place — so you can stay in the song.
