A desktop spreadsheet that calls OpenAI, Anthropic, and local models for text and images in cells. Add reusable context "bwocks" (persona, instructions, files), reference them in prompts, and switch out context sets in seconds.

I'm a veteran digital maker. After years of hating spreadsheets (particularly how they integrate with LLMs) I decided to make a spreadsheet I love and use every day. I think you'll like it too. ❤️
Turn columns into AI functions. Reference cells and context packs. Get structured text and image outputs back into the grid. Tweak and reformat outputs with AI Cleanup.
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.
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.
Create columns that call models using other cells as inputs—classification, extraction, rewriting, summarizing, transformations.
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).
Add PDFs, docs, images, CSVs, notes—name them—and reference them from any AI Column so outputs stay grounded and have context.
Bwocks isn't just for data nerds. Designers, writers, and artists get superpowers too.
Color palettes as context
Save and generate color palettes as context bwocks. Reference your brand colors in prompts so AI outputs stay on-brand.
Rich text in cells
Work with formatted text right in your spreadsheet. Write copy, notes, and documentation without losing structure.
Bulk AI image generation
Generate images in bulk with your context bwocks. Feed in prompts, styles, and references—get back a grid of visuals.
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.
Bwocks is already useful today. These are the next pieces we're snapping into place.
Chat with your grid
Ask questions, generate formulas, transform ranges, and explain what's happening in a sheet.
Chart Studio
Make charts fast, then tweak them like a designer. Great defaults, precise control.
More AI functions
Extract, classify, normalize, validate, translate—plus better structured outputs for real workflows.
Pivoting + grouping
Summarize, slice, and roll-up data like you expect. Grouping, aggregation, and sane defaults.
Webhook / API columns
Call any API, map JSON into cells, and wire Bwocks into your stack without leaving the grid.
Pre-built Bwock Towers
Ready-to-use context collections for common tasks—SEO analysis, content writing, data cleanup, research. Stack them, tweak them, make them yours.
Workflows
Chain steps across sheets: AI → cleanup → enrich → export → notify. Build repeatable systems, not one-off magic.
Roadmap is direction, not a contract. But we ship.
Keep using what you bought, even if you stop renewing.
Available for Windows, macOS, and Linux. Use it locally, offline (with local LLMs), and forever once downloaded.
