Your spreadsheets' systems meet your (and your LLM's) creativity.

Turn columns into AI functions. Reference cells and context packs. Get structured outputs back into the grid. Tweak and reformat outputs with AI Cleanup.

Bwocks make context (re)usable

Prompts, notes, PDFs, instructions—end up copied, pasted, tweaked, and spread across chats. It's long, scattered, and fragile. Context Bwocks standardize 10 of the most common context types and can be grouped into Bwock Towers to import, export, and swap out quickly.

AI Cleanup turns output into data

Right click any cell range to rewrite, normalize, validate, or restructure results. Enforce schema, flatten and split JSON into columns, and make outputs consistent without leaving the grid.

AI Columns: prompt in, results out.

AI Columns: prompt in, results out.

Create columns that call models using other cells as inputs—classification, extraction, rewriting, summarizing, transformations.

Context Packs you can swap in bulk.

Context Packs you can swap in bulk.

Save personas, instructions, and rules as named blocks. Switch a whole 'Bwock Tower' from 'strict JSON' to 'friendly copywriter' instantly.

Load real work (and play).

Load real work (and play).

Add PDFs, docs, images, CSVs, notes—name them—and reference them from any AI Column so outputs stay grounded and have context.

Desktop-first. Your keys. Your models. Your data.

Bring your own API keys

Use OpenAI / Anthropic without a middleman. You control spend and access.

Run locally when you want

If you have local LLMs installed, Bwocks can run offline-friendly workflows.

Local-first by default

Your sheets live on your machine. We don't sell or look at your data.

Swap context sets

Move between projects by switching entire context packs in a few clicks.

A picture is worth... well a fraction of a Tower.

Roadmap (even if you're older you can still play with bwocks)

Bwocks is already useful today. These are the next pieces we're snapping into place.
