Kahani Mitra

Kahani Mitra ("Story Friend" in Hindi) is a voice-powered creative story companion app for Indian children and adults of all ages. The child speaks their story aloud, and Mitra — the app's AI persona — listens, enhances, and helps grow the story with suggestions, rewrites, grammar help, and creative guidance. Built for Android, it works both online (with full AI features) and offline (stories saved instantly, AI applied when internet returns).
Voice Story Recording
The core experience. The child taps a microphone button and simply speaks their story aloud.
Live transcription — speech is converted to text in real time on screen as the child speaks, using Android's built-in Google Speech Engine (free, no extra cost)
Indian English optimised — uses en_IN locale for better recognition of Indian names, places and accents
Offline-first — if there is no internet when recording ends, the raw transcript is saved immediately with a friendly notice. No blocking dialogs, no waiting
Continue recording — a child can add more to an existing story by recording again, and the new speech is appended
AI Story Enhancement (Powered by Google Gemini 1.5 Flash)
When recording ends and internet is available, Mitra automatically runs three All AI responses draw from Indian culture: Panchatantra tales, festivals like Diwali and Holi, animals like elephants and peacocks, and Indian settings.

A 126-word stop-word list prevents common words like "Upon", "Once", "Far" from being mistaken for character names
Story Hints (Suggestions)
Each story has up to 4 active creative hints visible on the story screen. These are generated by Gemini referencing the actual story content.
Writing Assistant —
A full-screen bottom sheet with five AI-powered writing tools:
Tab 1 — Grammar Fix
Scans the entire story for spelling mistakes, wrong verb tenses, missing capitals, run-on sentences, repeated words and punctuation errors. Returns the corrected story with a list of every change made
Tab 2 — Complete Sentence
Reads where the story currently ends and suggests 3 different ways to continue from that exact point — one action-focused, one emotion-focused, one magical. Each is 1–2 sentences. The child taps one to append it.
Tab 4 — Apply Suggestions
Shows all unused hints. Tapping one asks Gemini to write the hint into the story as a natural continuation (2–4 sentences). The child sees a preview and accepts or rejects it.
Happy & warm ending
Surprising twist
Big adventure
Story Health Check
A full-page AI analysis of the story's quality, with honest scoring:

Pacing — does it flow well or feel rushed?
Character feedback — are the characters described and interesting?
Mitra's Top Suggestion — the single most impactful improvement the child could make
Encouragement — always ends with warm, age-appropriate motivation


Originality Check (Plagiarism)
Checks the story against well-known published works — classic fairy tales (Cinderella, Snow White), Indian epics (Ramayana, Panchatantra, Akbar-Birbal), popular children's books and animated films.

Returns an Originality Score (0–100)

Inline Story Editing
The child can tap an Edit button directly on the story text to fix it by hand:
Offline Mode & Queue Processing
Stories recorded without internet are saved instantly with AI.
The raw original transcript is always preserved alongside the AI-enhanced version.
Multi-language Recording
A languages screen lets the child switch the recording language. The speech engine supports 50+ languages including Hindi, Telugu, Tamil, Kannada, Bengali and more — so children can tell stories in their mother tongue.
