real Chitta answers, replayed in its real interface
This is Chitta's own window. Tap a question or type one. Each answer below was really written by Chitta's models on a Windows PC and is replayed word for word, faster than real time. Nothing you type leaves this page.
Pick a question below. Every reply is a real, recorded Chitta answer.
Demo replay of real answers. Chitta itself runs on your device; search and downloads use the network. Chitta can make mistakes.
Real answers recorded from Chitta 0.8.9 and 0.9.x test runs, replayed without changes. Times shown are the real times on the PC.
HOW CHITTA THINKS
channels that carry your question to the right helper
You ask once. Inside Chitta, several AI models on your device work together and hand the work to each other. Hover or tap a step to light its path.
Your question enters as energy, flows through the channels, and Buddhi sends each part to the helper that fits it best.
WHAT IT MAKES
the senses and hands that turn ideas into things
One assistant, many skills. Each one is a specialist that Chitta calls when your task needs it.
speech

images and drawings
Create and edit pictures from your words, and make diagrams or technical drawings. Review the result before you use it.
code and HTML games
Ask for a small tool, a calculator or a browser game. Chitta writes the code, and HTML pages and games open straight away so you can try them.
presentation decks
Turn notes into a PowerPoint deck with a clear structure. Edit and refine it like any other file.
research with sources
When you allow web access, Chitta gathers information and shows where it came from, and says plainly when it is unsure.
documents and spreadsheets
Draft Word documents, build Excel spreadsheets and summarize your own files, ready for you to review and share.
NEVER FAILS TO ANSWER
four ways through when memory runs short
Prāṇa senses how much free memory (RAM) and processor your computer has, and sets a safe pace. If memory gets tight, Chitta does not just stop. It works through four steps, in order:
ask
It gently suggests closing apps you are not using.
give back
It frees its own memory by unloading idle models and compacting the conversation.
divide
It splits the task into smaller steps or uses a smaller model, saving checkpoints along the way.
answer anyway
The best-fitting model still answers, with an honest note about what the memory limit affected.
checkpoints that resume long work
Long tasks are saved in steps, so work can pick up from the last checkpoint instead of starting again.
getting better with practice
Chitta is designed to improve itself over time, keeping useful lessons from earlier work on your own device.
PRIVATE AND OFFLINE
self-reliant: your PC, your data, your control

Honest limits. AI can make mistakes. Chitta shows what it checked and what still needs your review. Speed and what runs well depend on your computer.

Windows 0.9.11: Arch-Router's waiting time has one owner set from how long routing really takes on this PC, and a timed-out routing request no longer blocks later turns; pictures are planned against what really finished on this PC and a memory stop is reported as low memory; a stored coding-model memory peak far above what the model file can need is set aside for recalibration, with the 2 GB floor unchanged. Includes 0.9.7, 0.9.8, 0.9.9 and 0.9.10, which were not published on their own: Arch-Router routes again, programs are checked by running them, multi-part programs are planned instead of declined, and a chat keeps its context when it moves between models. Everything in 0.9.6 stays: Chitta can now use a plugin you install yourself in C:\AI\Chitta\plugins (Chitta never ships one): after you agree once, matching questions are answered by it in the chat, Prāṇa checks memory before it runs, and keys stay in Windows secure storage; plugin examples are prepared in the background so they never hold up chat, pictures or web answers; and Arch-Router's trained adapter now really loads in the app. Includes the 0.9.5 plugin slot, which was not published on its own. Everything in 0.9.4: Arch-Router answers with a short route name using a small Chitta-trained adapter, so routing is quicker (a quick check on one Surface PC: about 0.25 s instead of 0.74 s for the routing answer); a neural chain check keeps only clear single requests away from Arch-Router; Rakṣā locks face pixels only when you ask and finds the faces itself; photo-reference pictures use the strongest model that can take a reference and say why; first-run setup selects Buddhi · Mārga, Cakṣu, Smṛti and Nyāya by default; and the 🎮 games orb is always at the bottom-right. Everything in 0.9.3: Requests are routed by meaning: a quick neural check for clear asks and Arch-Router 1.5B for longer, pasted or multi-step ones, with requests that need real-world facts starting with web research; Vāk never routes or takes picture, code, research or PC work; and each answer has Regenerate and Re-route buttons. Includes the 0.9.2 speed-aware model choice, which was not published separately. Everything in 0.9.1: Writing, explanations and careful questions now use the strongest model that fits instead of the quick 2.6B model; nothing is loaded when Chitta starts; a pasted prompt is read as your request; naming a model for one step applies to that step; and Prāṇa has a clearer memory view that trims idle background apps (nothing closed) before choosing a smaller model. Everything in 0.9.0: Coding work stays on Śilpī with its full working context and never drops to the small 2.6B quick model while a better model fits; naming a model ("handover to Citra Uttama") always uses it, with the last file handed over; Prāṇa shows a live memory panel and can trim idle background apps (opt-in); documents are created again, streamed text stays visible, and computer control always asks first and hands back. Everything in 0.8.9: The retry card now appears when the check finds something to improve, with your answer kept; an honest "couldn't finish" no longer shows a passing review. Everything in 0.8.8: Simple asks answer fast; each answer is checked once and you choose whether to retry with the suggested improvements (Deep and Thinking hand you an improved prompt); coding keeps only the best version of a file; an honest closing message on low memory that names any files written; a smoother progress panel; optional Hasta computer helper (UI-TARS) downloadable and verified from Downloads; click the Chitta name or logo for About Chitta (version, credits, thanks to Sadhguru). Changes and limitations.
Application update for Chitta 0.9.6, 0.9.4, 0.9.3, 0.9.1, 0.9.0, 0.8.9, 0.8.8, 0.8.7 and 0.8.6 - 177.8 MB. Apply through Chitta's update check; do not run this file. Other installations need the full installer.
