Aitne vs Reyn

Aitne and Reyn are both personal assistants tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Aitne

Aitne is a local-first, open-source personal agent that runs on your machine, wakes at 04:00, pulls from your calendar, email, GitHub, and Markdown notes, and drops a one-page briefing into your Slack, Telegram, Discord, or WhatsApp DMs before your day starts. Hourly nudges surface urgent emails and pending PR reviews throughout the day. By evening it journals what actually happened, building a Markdown knowledge base you own entirely. The agent runs via npm with no cloud dependency — your data never leaves your machine. The ceiling appears fast: this is a single-user, single-machine system, and anything requiring team-wide coordination or multi-account enterprise integrations lives outside its scope.

Reyn

Reyn passively records screen activity and surfaces it through a Q&A interface — ask what you worked on yesterday, and it pulls an answer from your actual session history, not from a search index you remembered to populate. A morning email digest recaps open items and recent completions, so you're not reconstructing your week at standup. The workflow capture feature watches you complete a process once, then documents the steps — which is useful for handing off SOPs without writing them from scratch. The hard ceiling appears the moment you need this on Windows or in a team context: Reyn is Mac-only and the data model is per-device, not shared. Teams that need collaborative activity logging or cross-platform coverage will find no path forward here.

Pros	Runs the full agent loop — plan, act, reflect — on your local machine with no cloud dependency, which means your calendar, email, and GitHub data never transit a vendor's infrastructure. MIT-licensed and installable via npm, so you can audit, fork, and modify the scheduling logic or briefing format without waiting for a vendor roadmap. Delivers morning briefings and hourly nudges directly to Slack, Telegram, Discord, or WhatsApp, so you receive proactive context in the app you already live in rather than opening a separate dashboard. Markdown-based knowledge journaling writes outcomes to plain files you own outright, which means your daily reflections remain readable and searchable without the tool installed. GitHub integration surfaces PR reviews and repository activity in your morning brief, so pending teammate blockers do not stay invisible until standup.	On-device screen journaling means your screen contents — client work, code, internal docs — never transit a vendor's cloud, so you get AI-powered recall without the data exposure that cloud activity trackers carry. Live screen context at query time, not just historical indexing, so answers about 'what am I looking at right now' are grounded in the actual present state of your desktop rather than a stale snapshot. Workflow capture documents a process from a single live run-through, so you can hand off SOPs to a teammate without separately writing documentation after the fact. Morning email digest surfaces open items and recent completions automatically, so you're not reconstructing your week from memory at the start of each day. Multi-provider AI support, so you're not locked to one model vendor — if API costs or model quality shift, you switch providers without changing how your screen data is stored.
Cons	Integrations are fixed at calendar, email, GitHub, and Markdown — there is no described plugin or extension layer, so the moment a team needs Jira, Linear, Notion, or Salesforce context in their briefing, they are editing the agent source directly or abandoning the tool. Single-user, single-machine architecture means there is no shared context, no team briefing, and no multi-account support; a team lead who needs their agent to coordinate across reports' calendars or repositories has no path forward here and moves to a hosted multi-user alternative. No API surface is exposed by the agent, so wiring Aitne into a broader automation stack — triggering it from CI events, reading its journal output in another system — requires direct file-system or codebase integration, which adds maintenance overhead the moment a second engineer touches it.	Reyn is Mac-only with no Windows support or self-hosted option described anywhere on the vendor page — a user who splits their work across platforms loses the journal entirely for their non-Mac sessions, and there is no documented path to extend coverage. The data model is per-device and there is no API or shared workspace feature, which means workflow documentation captured by Reyn cannot be accessed by a teammate directly from the tool — teams expecting a shared activity log or collaborative SOP repository will need a separate system, at which point Reyn becomes a personal note-taking layer rather than a team workflow tool. AI inference routes through external model providers, so the local-first claim applies only to raw screen data — queries still require an outbound call to whichever AI provider you configure, which means teams operating in fully air-gapped environments cannot use Reyn as described.

Bottom line

Aitne is free while Reyn is paid; Aitne is open source. Choose based on which difference matters most for your workflow.
