🌿 Tahal: A Little Less Screen, A Little More Green

Description and use

Tahal is a voice‑first walking guide that runs locally, keeps the phone in the pocket, and eliminates screen distraction during outdoor walks.

Problem

Users want to go for a walk but are distracted by screens; existing apps require looking at the phone.

Outcome

Tahal enables users to walk outdoors with a spoken guide, reducing screen time and keeping the phone in the pocket. It runs entirely locally, preserving privacy and offline functionality.

Workflow

• 1. User opens Tahal and sets duration, guide personality, and language.
• 2. Tahal (via local Gemma model) generates a short walk script.
• 3. User puts phone in pocket; screen turns black and a press‑and‑hold wakes it.
• 4. Tahal speaks the walk stop‑by‑stop with chimes, using text‑to‑speech.
• 5. After the walk, user can journal a line and download a shareable walk card.

Evidence

Tahal (टहल, Hindi for a stroll, the thing your dadi tells you to do after dinner) fixes that by being something you listen to.

Source

Setup takes about twenty seconds. The walk takes as long as you like and needs the screen for none of it.

Source

To have Gemma write walks for you, three commands (you need Node 18+ and Ollama):

bash
ollama pull gemma3:4b
git clone https://github.com/Abhyudaysharma/TAHAL.git
cd TAHAL && node server.js
