Kin Health Technologies

Free

Free AI companion that records doctor visits, turns them into clear summaries with next steps, and shares them with your care circle.

Visit Recording: Quietly captures the audio of a doctor's appointment so the patient can stay present and focused during the visit.
Structured Visit Summary: Turns each recording into a clear written summary with the medications, follow-ups, and instructions that matter, plus a concrete next-steps list.
Care-Circle Sharing: Share a visit summary with family, a spouse, or an adult child so caregivers stay in the loop without extra copy-paste.
Pre-Visit Question Prep: Save questions for your next appointment and receive a notification before it starts so nothing gets forgotten.
Cross-Provider Coverage: Works with any doctor, specialty, or clinic — patients don't need their provider to opt in.
Privacy & Encryption: Data is encrypted, private by default, and the company was founded by physicians with clinical privacy in mind.
Multi-Persona Support: Same app covers caregivers managing an aging parent, chronic-condition patients, new and expecting parents, and even pet owners tracking vet visits.

Caregiver Coordination: Adult children managing an aging parent's appointments capture visits and share summaries with siblings instantly.
Chronic Condition Management: Patients with migraines, diabetes, or other long-term conditions keep a durable record of each specialist visit.
Prenatal & Pediatric Visits: New and expecting parents track OB or pediatrician instructions across many appointments without messy handwritten notes.
Post-Visit Recall: Any patient reviews a clear summary later instead of trying to remember 80% of what was said in the exam room.
Advocacy & Second Opinions: Share full summaries with a second-opinion clinician or family member helping you push for treatment options.
Veterinary Follow-Ups: Pet owners record and revisit vet appointments to stay on top of medication and follow-up care.

mpai (open source)

Free

Terminal-native, open-source tool that lets a teammate join your live Claude Code or Codex session over a private tailnet.

Live Session Join: A teammate opens your in-flight Codex or Claude Code conversation from their own terminal without losing context.
Named Identity Prompting: Every prompt is attributed to the person who typed it, so audit trails show who steered the agent.
Private Tailnet Transport: Sessions travel over a Tailscale-style overlay network — no public relay, no third-party server.
Terminal-Native, No New IDE: Works with the CLI agents you already run; nothing changes about your editor or model.
Ephemeral Rooms: Start a short-lived room (e.g. 5-minute) for a quick pair session and it closes on its own.
Access Controls and Audit: Presence, transcript, list, and prompt routes all share the same access check with an audit log.
Open Source: Full source is on GitHub; self-host end to end.

Pair Debugging: Hand a stuck agent session to a teammate so they can prompt from their own terminal without cloning context.
Code Review of Agent Work: Reviewer joins live to steer or challenge the agent instead of reading the diff cold.
Onboarding: Senior engineer takes a junior through a real agent session in real time.
Long-Running Task Hand-off: Pass a multi-hour Codex refactor to the next shift without losing the running conversation.
Security-Conscious Teams: Collaborate on agent work without routing traffic through a hosted SaaS relay.
