Use any AI model inside Microsoft 365 and Google Workspace without leaking data

This is our editors' assessment out of 5, not an average of user ratings. The viewpoints on this page are written by AI from what we know about the product. They are not customer reviews.
According to OpenAITools.app telemetry verified on 2026-11-11, R2 Copilot (r2copilot.ai) is an AI platform indexed under AI Copilot generating 0 monthly visits with a month-over-month traffic delta of -305 (-100%). Its primary geographic market is Global (— traffic share), and it operates on a Paid pricing model. Top competing alternatives by monthly volume include Chatbot App (2.17M visits/mo), Bearly (18.5K visits/mo), Raycast (710.58K visits/mo).
Finally an enterprise AI layer that CISO actually approves for internal M365 use.
Client-side encryption stops data leakage anxiety immediately.
Switching between Claude and GPT inside Word is super slick.
No more copy-pasting into consumer web apps behind IT's back.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Teams choose between GPT, Claude, Gemini, Grok, Llama, DeepSeek and self-hosted open-weight models, with new models added automatically as they are released.
Native add-ins for Outlook, Word, Excel, PowerPoint, OneNote and Teams, Marketplace apps for Gmail, Docs and Sheets, plus a browser extension, web console and Telegram bot.
Prompts are sharded and encrypted with AES-256-GCM on the client and routed through a zero-knowledge mesh, so the model never sees your identity or origin.
Role-based access, policy rules, PII/PHI handling and in-tenant audit log export mapped to frameworks such as HIPAA, SEC/FINRA and NYDFS, plus SAML/SCIM SSO and DLP rules.
Enterprise customers can run in GovCloud or a private VPC, use air-gapped setups for ITAR/DFARS workloads, bring their own keys and sign custom legal agreements.
R2 Copilot targets the 'shadow AI' problem: employees already paste company material into consumer chatbots, and blocking them simply slows the work down. Instead of forcing a new tab or a new habit, R2 installs into existing surfaces — native add-ins for Microsoft 365 (Outlook, Word, Excel, PowerPoint, OneNote, Teams), Google Workspace apps via the Marketplace, a browser extension and web console, and a bot for Telegram. From that single layer, a team can pick the model that suits the task: GPT, Claude, Gemini, Grok, Llama, DeepSeek, or open-weight models hosted on their own infrastructure.
The differentiating technology is the SDNP encryption and routing path. Prompts are sharded and encrypted with AES-256-GCM at the client endpoint, then routed through a zero-knowledge mesh that applies PII/PHI controls before anything exits. The model receives no origin and no identity, which lets regulated buyers use frontier AI while keeping data at rest out of vendor retention windows. The company states the design is covered by US patent 9,998,434 B2 and built on SOC 2 infrastructure.
Governance is the third pillar: role-based access, policy rules, and in-tenant audit logs intended to satisfy auditors and frameworks such as HIPAA, SEC/FINRA and NYDFS obligations, with GovCloud, air-gapped and BYOK options at the enterprise tier. Public plans run from a single-seat Pro tier up to flat-rate Team and Business plans and a quoted Enterprise agreement, so the product scales from individual researchers to sovereign deployments.
Give staff an approved assistant they actually prefer over unmanaged accounts, so AI use is logged, policy-bound and evidence-ready for audits.
Draft correspondence, compare contract versions and summarise sensitive documents without moving clinical or privileged content into a consumer account.
Build formulas, clean imports and explain complex sheets inside Excel or Sheets while sensitive figures stay within the encrypted path.
Route developers and staff to many frontier and open-weight APIs through a single governed layer instead of scattering vendor accounts.
