Workspace chat with verifiable sources

Search documents. Bring live API data into the answer.

Bring files and approved read-only API operations into one workspace. Keep the supporting sources visible and continue the same conversations on Web, iPhone, and iPad.

What it solves

Questions should not start with hunting for the right file or endpoint.

Most teams already have the source material. ContextStacker gives them a clearer way to add it, ask about it, and check what supported the answer.

Documents stay usable

PDF, DOCX, Markdown, TXT, and CSV files become searchable workspace context instead of isolated attachments.

API execution stays controlled

Import OpenAPI resources, enable approved read operations, and let chat run them only when current data is needed.

Answers stay reviewable

Each conversation keeps sources visible so teams can inspect the document or API result behind an answer.

How it works

Turn source material into sourced answers.

Start with the files and API catalogs a team already uses. ContextStacker parses documents, executes enabled API operations when needed, and keeps the resulting sources available for review.

Workspace chat history

Continue conversations across devices and switch workspaces without losing the surrounding context.

App for iPhone and iPad

Keep the same workspace in reach.

Sign in with the same account to continue workspace conversations on iPhone and iPad. Ask across workspace documents, receive answers that can use enabled APIs, and see the source information attached to each response.

Use the Web workspace to manage documents, API resources, members, and workspace settings. The iPhone and iPad app is designed for everyday questions, history, sources, plan details, and usage on the move.

Continue the same conversations

Start a new chat or return to workspace history without rebuilding context on another device.

See what supported the answer

Review the document and API source information cited by each response.

Manage the essentials

Switch workspaces and review account, plan, usage, and signed-in devices from the app.

Operations knowledge

Use policies, reports, and shared files to answer recurring operational questions with source context.

Live API execution

Execute enabled API operations from chat while keeping operation selection, credentials, and request scope controlled.
