LOCAL FIRSTPIXEL POWEREDYOUR HARDWARE

A tiny helper for real work.

Bitzi lives on your device, turns requests into transparent jobs, and keeps your files, memory, and model close to home.

INTERACTIVE CONCEPT

See how Bitzi thinks about a job.

A conversational local assistant with visible permissions, expandable tool calls, and cited results. Load the 3.8 GB Bonsai brain once to generate answers entirely on this device.

LOCAL SESSION

Hey! I’m Bitzi.

Ask me something, or give me a job. I’ll show every tool I touch and keep sources beside the answer.

Bonsai replies and selected documents stay on this device. General web search uses a protected service and falls back to Wikipedia; Python is not connected yet.

THE TOOLBOX

Useful enough to keep open.
Cute enough to want to.

Bitzi is not a mascot pasted onto chat. The character communicates what the system is actually doing.

JB
01

Jobs, not lost chats

Objectives, permissions, progress, sources, failures, and artifacts stay together on one durable job card.

SR
02

Permissioned search

Bitzi raises its antenna only when you allow network access, then keeps citations beside the answer.

PY
03

Sandboxed Python

The planned Pyodide worker will use cancellation, visible code, selected files, and no network by default.

MM
04

Memory you control

Local memory controls are on the roadmap: inspectable, editable, exportable, and deletable by design.

LM
05

Your model, your hardware

Start with a cached WebGPU model, then use native MLX, Metal, CUDA, or llama.cpp in desktop mode.

EX
06

Real takeaways

Exportable reports, cleaned data, notes, and code are planned as the next step beyond conversation history.

LOCAL BY CONSTRUCTION

The website is the workshop.
Your device supplies the power.

Prompts, memory and job history

Stored locally unless you explicitly export or invoke a network tool.

ASKS FIRST

Files, search and future OS tools

Each capability has a visible permission and a record in the job timeline.

NO MAGIC

Compatibility before download

Bitzi checks WebGPU and storage before asking for a multi-gigabyte model download.

QUALITY MODEDESK

Desktop app

A Tauri shell adds reliable local runtimes and carefully permissioned operating-system tools.

  • Ternary Bonsai 27B target
  • MLX / Metal / CUDA / llama.cpp
  • SQLite and selected folders
  • Scheduled jobs while running
EXPERIMENTALPHONE

Pocket Bitzi

PWA compatibility first, followed by native runtimes where mobile memory and thermals permit.

  • Honest device preflight
  • 1-bit phone-oriented model
  • Document picker and share sheet
  • No fake background promises

BUILD ORDER

Small steps.
Visible proof.

Prove the unusual part first: a transparent, useful 27B-class helper running locally in a static site.

  1. 01
    NOW

    Character + workbench prototype

    Code sprite, product layout, interactive job simulation, requirements.

  2. 02
    NEXT

    Device preflight + model loader

    WebGPU, storage estimates, download, cache, progress, clear controls.

  3. 03
    CORE

    Local chat + job persistence

    Worker inference, streaming, IndexedDB, memory controls, export.

  4. 04
    TOOLS

    Source-backed web search

    Brave finds relevant sites, Cloudflare Browser Run reads them, and Wikipedia remains the fallback.

  5. 05
    SHIP

    Compatibility lab + public beta

    Tested-device matrix, GitHub release, demo video, honest Reddit launch.

BITZI IS JUST WAKING UP

Tiny model.
Real work.

A local helper should feel personal without turning your personal data into somebody else’s product.
