Most knowledge work doesn't need a rocket. Bang gets it done on low-cost open models (or bring your own), imports your Claude history, and works across Word, Excel, PDFs, and the browser — for a fraction of the price. Just go.
Rolling out to teams — see Bang for Enterprise
Runs on OpenAI, Anthropic, Google, or any OpenAI-compatible endpoint — or fully offline, with no telemetry.
Bang isn't a chat window you copy answers out of. It opens the files you already work in, makes the edits, and hands them back for your review.
Fill PDF forms instantly with Bang — pulling answers from your other documents. Works even with non-interactive, flat forms.
Pivot tables, charts, formulas, and more — a fully featured, AI-native spreadsheet.
Editor powered by ONLYOFFICE.
Tracked changes, formatting, images, and more — a fully featured Word editor with AI built in.

Bang drives a real browser to research, gather sources, pull data into your sheets, and check its own work — then cites what it found.
Connect MCP servers — Google Workspace, Linear, your own — and Bang uses them as tools. One click to connect, no config files to hand-edit.
Ask for something big and Bang researches first, writes a plan you can approve, then works the checklist — delegating focused sub-tasks to subagents.
Bring your Claude chat history into Bang and pick up right where you left off — your conversations become a searchable, workable part of your workstation.
Opens and edits the real files you already use — Microsoft Office and Google Workspace.
An agent working in your real files needs a human in the loop, not blind trust. Bang shows you exactly what changed and waits for your approval on anything that matters.
Use your own subscriptions or API keys. Frontier models when you want the best answer, self-hosted models when you need privacy or cost control — and Bang runs fully offline, with no telemetry.
Point Bang at your documents — a Word file, a spreadsheet, a stack of PDFs — or start from a blank one.
Say what you want in plain language. Bang plans, works across your files, and pulls in the browser or your connected tools as needed.
Bang shows every change it made. Accept what's right, send it back for another pass, and save when you're happy.
