Pensieve

Pensieve is a company brain for AI agents. Connect the tools your team already uses, such as Slack, Notion, Google Drive, GitHub, Linear, HubSpot and meeting notes, and Pensieve builds and maintains cited Pages about your customers, projects, people and decisions, rewriting them as the sources change. Every agent your team uses, including Claude, Claude Code, ChatGPT, Cursor and Codex, reads the same account over MCP, so agents start from a current understanding of the company instead of piecing it together from scattered tool searches. Every claim links to its source, sensitive topics can be restricted to the people allowed to see them, and your context can be mirrored as Markdown to a GitHub repository you own.

Quixli

Document software for proposals, scopes, and technical documentation. Quixli is built for the work you hand to someone else and then wait on: client proposals, quotes, scopes of work, user guides, architecture docs, runbooks, and handover packs. Instead of starting from a blank page, create documents from reusable templates, share them with a single link instead of a PDF, and understand how they're actually used. What makes it different? Know how documents are used — see when a document is opened, which sections receive the most attention, what gets skipped, and whether readers return later. Quixli measures what was on screen and for how long; it does not claim to know whether someone read the text. Built for client proposals — interactive pricing tables, package selectors, in-scope/out-of-scope comparisons, cross-referenced terms, and variables that populate client details throughout the document. Made for technical teams — Mermaid diagrams, Excalidraw, syntax-highlighted code, math formulas, tables, charts, timelines, collapsible sections, tabs, footnotes, and synced content blocks that stay consistent across documents. Everything in one place — embed Figma, Google Docs & Sheets, YouTube, Vimeo, Loom, PDFs, and file attachments, so recipients follow one link instead of six. Secure sharing — protect links with a PIN, set expiration dates, and export any document to PDF when needed. Recipients can always see exactly what analytics are collected from the document link. Free plan available. No credit card required.

Sentra.app

Sentra is a managed organization memory for teams and their AI agents. It connects to more than 200 tools, including Slack, Gmail, Outlook, Google Drive, Microsoft Teams, Jira, Confluence, Notion, GitHub, Salesforce and HubSpot, and turns what flows through them into facts that record who said what, when it became true and when it stopped, with the source system's permissions attached. Employees ask questions in Slack or the Sentra app, and AI agents built on Claude, ChatGPT, Gemini, Cursor or custom frameworks read the same memory over a REST API and MCP, so people and agents work from one current answer instead of stale documents. Sentra tracks decisions and commitments, prepares meeting briefs, and flags when facts change or conflict. It is SOC 2 Type II and ISO 27001 certified, deploys in the cloud, an isolated VPC or on-prem, and does not train on customer data. Sentra at sentra.app is unrelated to Sentra.io, the data security company.
