Architecture & Engine

Cognitive Tools Built for Deep Reflection & Clarity

Designed to remove friction from typing, organizing, and synthesizing knowledge on Android devices.

Tool 01 • Proofreading

Intent-Preserving Auto-Correction (/fix)

Most AI text tools rewrite your thoughts into wordy, generic prose. ThoughtBook LM's precision engine detects misspellings (e.g. "orage""orange", "necer""necessary") and grammatical errors while strictly retaining your checklist boxes (- [ ]), formatting, and distinct personal voice.

✓ 1-Tap 'Replace All' directly replaces typos in your document
Tool 02 • Socratic Synthesis

Socratic Thinking Partner (/deepen)

Rather than telling you what to think, ThoughtBook LM acts as a mirror for your cognition. When you run /deepen, the engine analyzes your writing to find logical blind spots and formulates one sharp probing question to challenge your assumptions.

Tool 03 • Task Extraction

Actionable Task Extraction (/tasks)

Convert unstructured reflections, brainstorms, or meeting minutes into prioritized, actionable to-do items. If no direct tasks exist, the engine proposes logical next steps.

Tool 04 • Audio Wellness

Mindful Focus Audio Engine

Enhance your concentration with built-in offline instrumental focus tracks (Deep Healing) and natural soundscapes. Supports custom offline audio file imports and an auto-off timer (15m, 30m, 60m).

Tool 05 • Local-First Architecture

Pure SQLite Local-First Privacy

Your data is never monetized or exposed. Everything is stored in high-performance local SQLite on your phone.
