Tempr is a bring-your-own-key (BYOK) extension: a rich in-IDE chat, inline completion, and agent toolset inside Visual Studio that works with first-party providers (OpenAI, Anthropic, Google) and aggregators (OpenRouter and others). Add your own API key and pick whichever model fits the task — nothing routed through a shared pool.
Choose a plan See it in action
No more tab-switching to a browser. Chat, complete, and refactor without ever leaving Visual Studio.
Connect directly with first-party providers (OpenAI, Anthropic, Google, xAI) or an aggregator (OpenRouter and others) using your own API key — no shared usage pool, no vendor lock-in. Required on every plan.
Rich Markdown and code block rendering, one-click copy/insert at cursor, slash commands (/explain, /fix, /tests, /doc), and full chat history you can revisit anytime.
A real tool-calling loop that reads, searches, and edits your codebase and runs whitelisted commands — choose Interactive (approve every change), Bypass (auto-apply edits), or Autopilot.
Type @debugger, @test, @security, @review, @docs, @refactor, @modernize, @profiler, @git, or @plan for a specialist prompt and tool scope. Standard unlocks the full built-in set; Pro adds custom personas you define yourself.
The agent can hand focused sub-tasks off to specialist personas mid-turn — e.g. delegating root-cause analysis to @debugger while it keeps working — running several in parallel when it helps.
Embedding-based search over your solution finds conceptually related code even when the wording doesn't match — not just grep with extra steps.
The agent can inspect the live call stack and locals and evaluate expressions during a debugging session, for context-aware help grounded in your actual running process.
Lists and runs your tests with structured pass/fail results, reads live compiler diagnostics, and understands your solution's project references and call graph.
Ghost-text style inline completions that suggest the next line as you type, tuned per-scenario to the model you prefer.
Connect external MCP servers to extend the agent with your own tools and data sources.
Chat sessions, tool preferences, and custom personas are stored locally by default, with optional cloud sync (Standard+) so your setup follows you across machines.
Standard and Pro (and Teams, coming soon) both unlock the full model catalog — Pro gets new models immediately, Standard about 7 days later — plus deeper agent features like custom personas, multiple saved sessions, and higher agent-turn limits on Pro. Managed via Stripe subscriptions with automatic license-key issuance.
This is the actual supported-provider allowlist Tempr enforces server-side today — not a wishlist. Add your own API key for any of them and Tempr talks to that provider directly.

Install the Tempr extension into Visual Studio from the Marketplace or a VSIX package.
Subscribe to Standard or Pro — license keys are emailed automatically after checkout, and activate in seconds inside the extension.
Bring your own key for a first-party provider (OpenAI, Anthropic, Google) or an aggregator (OpenRouter and others) — stored encrypted, locally.
Open the tool window, pick a model from the dropdown, and start chatting, completing, or delegating to an agent.
