Panda's Notebook started as a personal tool to fill a need that I couldn't find anywhere else and became the all-in-one powerhouse that continues to grow and something worth sharing with every songwriter who's ever struggled to find the right word at 2am or is sick of managing a featureless app plus multiple tabs all while trying to write a song.
"I was using a basic text editor while having multiple tabs open every songwriting session — a rhyme search page, a thesaurus, a dictionary, a notes app, a recording app, an audio player and sometimes an AI chat session in what felt like endless tabs and pages that had to be managed or reloaded all the time. It made songwriting feel unenjoyable, it was hard to stay focused, and difficult to find inspiration and creativity to write any song. So I started building Panda's Notebook to see if I could eliminate some of my stress and it slowly became what I call my songwriting sanctuary. A single app allowing me to have all the tools I use plus some in an app that is easy to use."
Panda's Notebook was built out of a genuine frustration with how fragmented the songwriter's digital workspace had become. Every tool that was supposed to help was sitting in a different browser tab or app — none of them talking to each other, none of them understanding what a song actually is.
The goal was simple: build one app that holds everything a lyricist needs, designed around the real structure of a song — not a blank document, not a note-taking app, not a general-purpose word processor or text editor.
After months of writing, testing, scrapping, and rewriting, Panda's Notebook is what that process produced. It's opinionated, it's focused, and it's built by someone who actually uses it to write songs.
There are no tiered or required monthly subscriptions. No usage limits. No data harvesting. You own your songs. If you have a Gemini AI subscription and decide to use your own AI API key for the song assistant it's stored and saved encrypted, secure and locally on your machine. Your license is tied to your account and bound to your device's unique hardware ID.
The AI assistant is deliberately not a black box — it's transparent about what it does, gives you multiple options instead of one answer, and is specifically designed not to flatten your voice into something generic. It has been fine-tuned to be a song writers assistant in every way.
Every design decision in this app starts with the same questions: what does a songwriter actually need right now, in the middle of writing? Is it needed and useful? Will it increase productivity, creativity, and data integrity. Priorities are based on importance and overall usefulness.

A plain-language explanation of what we collect, what we don't, and why. We strive to collect as little information as possible and the little we do collect is kept safe and your remain in control of it. It's not everyday you get to be in control of the big RED bottom. But we happily give that control to you. That way at anytime you become unhappy or just want to clear out. Click the button "big RED button" for the section you want to delete your data from and just like that, it's removed.
Panda's Notebook collects the minimum information necessary to provide the service. Specifically:
Panda's Notebook uses the following third-party services:
To validate your license and prevent a single license from being shared across unlimited machines, Panda's Notebook reads a hardware identifier from your device. This identifier is hashed using SHA-256 encryption before it ever leaves your machine. We store the hash, not the raw hardware ID. This hash cannot be used to identify your device for any purpose other than license validation.
You can delete your account at any time from the User Profile screen. Deleting your account removes all profile information other than your login account and license from our systems. Your license record is retained for license validation, for license recovery, and to prevent fraudulent chargebacks.
Privacy-related questions can be asked via email at privacy@pr0t0typ3dapps.com Response time within 5 business days to privacy-related inquiries.
What you can do with Panda's Notebook, what I ask in return, and what happens if something goes wrong.
When you purchase Panda's Notebook, you will receive a personal, transferable license to install and use the software on any Windows 10 or new machine. Your license key is permanently bound to the email address used to activate the license and to the hardware of your activated device. Your license is transferable between devices. You can deactivate your license within the app and then reactivate it on another system.
You own everything you write in Panda's Notebook. Your lyrics, song meta data, tags, notes, AI assistant Chat history, profile information, song templates and chord annotations. It all belongs to you. We make no claim to any content you create using this software.
By using the AI Song Assistant feature using the provided API free monthly renewing tokens or booster packs for added token allowance for access in the Full version or your own Gemini subscription API key, you are communicating directly with Google's Gemini API designed for song writing. The content of those conversations is governed by Google's Terms of Service, not ours. We do offer you a way to delete your AI chat history within the app. This does not remove any information that Google may retain.
Your one-time purchase includes full access to all features the app provides. Access to the updates distributed through the built in auto-update or manual update system for the first 12 months from purchase date or for the lifetime of the current version of the app at time of purchase. For example, the v1.x series will continue to receive updates until the v2.x series is released. We reserve the right to change pricing for major version upgrades (v2.0 and beyond), though current customers will always receive a discounted upgrade path and will always have access to all current version related bug fixes, hot patches, etc for the lifetime of the app. "Version upgrades are not required to continue using your current version"
Support is provided on a best-effort basis via email, in app bug submission or forum submission. We do not offer guaranteed response times for support inquiries but strive to respond typically in 1–2 business days.
We offer a 14-day refund window from the date of purchase, if you are not satisfied with the software. To request a refund, you may request one via the payment center, you can contact me using the contact form on the website or you may email me at support@pr0t0typ3dapps.com with your purchase receipt. If communication or processing extends beyond the 14-day period, the refund will still be honored as long as the original refund request was submitted within the 14-day window. Refunds are not available after the 14-day window has passed.
