## Heidi

Heidi began as an AI medical scribe and has grown into a broader clinical AI partner for physicians, nurses, allied health staff, and health systems. Its core job is documentation: the app listens to the visit as it happens, writes the note, and keeps working afterwards by drafting referrals, GP letters, care plans, and patient recaps. Every fact it produces is cited back to the clinical record, and nothing is sent to a patient until the clinician has read and approved it.

Beyond note writing, Heidi covers the recurring admin around a clinic day. Morning prep reads the appointment list and briefs the clinician one line per patient in appointment order. Note insights analyse the corrections a clinician keeps making and propose word library entries, auto-edit rules, and template changes. Follow-up digest pulls out every commitment made in the room, matches them to open tasks, and groups them by documented due date. There are also modules for MDT prep, shift handover, results follow-up, and filling PDF or Word forms from the session and patient record.

The vendor says Heidi supports 175M+ patient interactions worldwide and cites its own peer-reviewed safety research on note accuracy across many languages. It is available as a web app plus desktop builds for macOS and Windows that can dictate anywhere on screen and capture telehealth audio directly from the call. Healthcare organisations should evaluate it against local privacy, HIPAA, GDPR, and regional compliance requirements.

**Pricing & Plans:** Freemium. Clinicians can get started on a free tier, and paid subscription plans plus enterprise arrangements for clinics and health systems are available with demo booking. Because healthcare pricing is often seat- or organisation-based, confirm current rates on the official pricing page.

- **Ambient visit transcription:** Listens to the consultation in real time and converts it into a structured clinical note, with an emphasis on accurate drug names and specialty terminology.
- **Automatic note refinement:** Reviews the edits a clinician makes, groups recurring corrections, and proposes word library entries, auto-edit rules, and template changes to approve.
- **Document drafting after the visit:** Writes referral letters, letters back to the GP, care plans, and patient recaps straight from the finished note.
- **Pre-clinic and handover prep:** Builds the day's list, stages meds, allergies and recent results per patient, and drafts ISBAR-style shift handovers.
- **Desktop dictation app:** macOS and Windows builds let clinicians dictate anywhere on screen and capture telehealth audio directly from the call.

**Strengths:** Clinical accuracy is backed by cited, peer-reviewed safety research; Document flow extends well beyond the visit, covering referrals, handovers, recaps, and forms; Desktop app captures telehealth audio and dictates anywhere on screen; Supports many languages for transcription, useful for multilingual clinics

**Limitations:** Pricing is not fully public and typically requires contacting sales; Full value depends on integration with the practice's EHR and templates; Clinicians must still review and approve every output, so it does not remove the review step

## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI
