Duck AI vs Reyn

Duck AI 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.

Duck AI

Duck.ai is DuckDuckGo's browser-based chat interface that routes your prompts to leading AI models without requiring sign-up or storing your conversation history, per the vendor's stated privacy model. The free tier gives you access to a set of base models; advanced models with higher usage headroom are a paid-only feature tied to a DuckDuckGo subscription. There is no API, no self-hosted option, and no way to connect it to your own tooling — it is a chat window and nothing more. For a quick question, anonymous research, or a productivity task you do not want tied to an identity, it works cleanly. When you need to automate, integrate, or run more than a handful of advanced queries a day, you hit its ceiling fast.

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.

Attribute	Duck AI	Reyn
Pricing	Paid	Paid
Price	$9.99/month or $99.99/year for advanced models	$20/mo
Free trial	7 days	No
Open source	No	No
Has API	No	No
Self-hosted option	No	No
Platforms	Web	Mac
Pros	No account or sign-up required, so you can query any supported model without leaving an identity footprint — which matters when the research itself is the thing you do not want logged. Access to multiple AI models from a single interface, so you can compare outputs without maintaining separate accounts or API keys for each provider. Free tier with no usage friction for base models, so occasional users get real AI access without a billing commitment. DuckDuckGo's stated no-logging privacy model, so queries you run here are not fed back into a training pipeline or tied to a browsing profile the way they would be on most mainstream AI chat products.	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	No API means any team that needs to call a model programmatically — to power a feature, automate a task, or process data in bulk — cannot use Duck.ai at all. There is no workaround short of switching to a provider that offers API access. Advanced models are a paid-only feature with no standalone purchase path — they require a DuckDuckGo subscription, so teams evaluating Duck.ai specifically for model access are buying into a broader product they may not want. No persistent context or session history means every conversation starts cold. Users running multi-step research or iterative drafting have to manually paste prior context back in each time, which breaks any workflow longer than a single exchange. No self-hosted or local option means privacy-sensitive organizations that cannot route queries through a third-party server — regulated industries, legal teams, enterprise security requirements — have no deployment path here. Teams with those constraints move to self-hosted open-source models.	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

Duck AI and Reyn are closely matched on pricing model, openness, and API availability — pick by feature set and platform support in the table above.
