Use case · Updated 2026-06-02
Documents, spreadsheets & slides
Most AI tools stop at a wall of chat text. Liminal ships the deliverable: a document engine that plans, researches, composes, and renders real PPTX, DOCX, and PDF files with a quality gate, plus live connectors for Google Docs, Sheets, Slides, and Microsoft Excel.
From prompt to finished file
The document engine is a pipeline, not a single completion: plan the outline, research and collect sources, select assets, generate chart data, compose each section, lint the layout, repair what fails, then render. Output is checked against a quality score before export: if a deck doesn't pass, the agent iterates instead of shipping a draft.
- Slide decks (PPTX) with charts, images, and styled layouts.
- Reports and proposals (DOCX, PDF) with structured sections.
- Web research folded in with sources, when the task needs facts.
Work in the files your team already uses
With the Google Workspace connector, the agent reads and edits Google Docs, builds Sheets (including layout and column auto-fit), and assembles Slides directly in your Drive. The Microsoft 365 connector does the same for Excel workbooks, OneDrive files, and OneNote. One request can cross tools: pull numbers from a spreadsheet, summarize them in a doc, and turn the summary into a deck.
Spreadsheets that get built, not described
Ask for a budget model, a content calendar, or a cleaned-up export and the agent writes the actual cells: formulas, headers, formatting: in Google Sheets or Excel via the live connectors. For one-off files it can generate CSVs or build workbooks locally and hand you the file.
Memory makes the second document faster
Liminal remembers your conventions: brand voice, deck structure, the KPI definitions you corrected last month: in local memory and an optional Obsidian vault. The fifth report doesn't start from zero.
Quality gate before export
Rendered decks and reports are scored against AGENT_DOC_QUALITY_MIN (default 90). If layout or content fails lint, the agent repairs sections before you get the file. That matters for client-facing work where a sloppy chart or broken slide is worse than no deck at all.
Sample business prompts
- "Build a Q1 board deck from this spreadsheet: revenue, churn, and hiring."
- "Turn these meeting notes into a one-page client summary PDF."
- "Create a quote template in Word with our standard payment terms."
- "Clean this CSV and add a pivot summary in Google Sheets."
FAQ
Common questions
Do I need Microsoft Office or Google accounts?
Not for local rendering. PPTX, DOCX, and PDF files are generated on your machine and open in any compatible app. Connect Google or Microsoft only when you want the agent working in your live Docs, Sheets, Slides, or Excel files.
Can it use my data for charts?
Yes. It can read local files, spreadsheets, or web sources, generate chart data, and embed the charts in the rendered document.
How is this different from ChatGPT creating a PowerPoint?
ChatGPT often returns outline text or a downloadable file with limited layout control. Liminal runs a full document pipeline with research, asset selection, layout lint, and repair loops, and can write directly into your Google Slides or local PPTX.
Can the agent edit an existing deck?
Yes via Google Slides connector or by reading and patching local files. Ask for specific slide changes; writes go through approval when they affect shared Drive files.
