I built a prototype to turn pasted chat text into reviewable plan candidates.</p> <p>I shared Pakka? with my friend, who already had Ollama installed. He ran it locally on his device, got it working, and genuinely liked the project. That was encouraging: it showed me this idea mattered to someone beyond me.</p> <p>Pakka? separates confirmed, proposed, unclear, cancelled, and superseded plans. It shows the source lines behind each interpretation, keeps tasks and RSVPs out of calendar events, and requires a person to review an event before export.</p> <h2> Demo </h2> <p><a href="https://drive.google.com/drive/folders/1vZmR8WIu4WR2xkfzcchvyYpjZRZQePoA?usp=sharing" rel="noopener noreferrer">Drive folder</a></p> <h2> Code </h2> <p><a href="https://github.com/aditya-mnnit/pakka-hf26" rel="noopener noreferrer">View Pakka? on GitHub</a>.</p> <h2> How I Built It </h2> <p>Pakka? is a Node.js app with a Gemma 4 integration through Ollama. It asks the model for plan candidates with source quotations and line numbers, then checks that cited text appears in the supplied conversation. A person can edit and review candidates before exporting valid, confirmed calendar events. My friend ran it locally using his Ollama setup, and it worked on his device.</p> <p>The automated test suite passes 13 tests covering evidence checks, dates, cancellations, review requirements, and calendar export. This is a small software test suite, not a broad measure of model accuracy.</p> <h2> Why Does Open Innovation Matter? </h2> <p>Ollama let my friend run Pakka? on his own device instead of having to use a hosted model service. In local mode, chat text goes to the local Ollama instance; the optional hosted mode sends it to Google's Gemini API. That gives people a choice about where inference happens. The local run worked for my friend, though I have not measured model accuracy or compared it with a closed model.</p> devchallenge weekendchallenge hf26challenge
