evenfall vs Duck.ai, feature by feature
| Feature | evenfall | Duck.ai |
|---|---|---|
| Trains on your conversations | No — never used for training | No — DuckDuckGo and providers contractually agree not to train |
| Server-side chat storage / retention | Stores your history server-side until you delete it | Stores nothing on its servers; recent chats saved locally on your device (can be cleared or turned off), providers delete within ~30 days |
| Deleting a conversation | Hard-deletes the database row — no soft-delete, no recovery window | Clear local history any time; there is no server copy to delete |
| Anonymity / account required | Requires an account (email one-time code or Google sign-in) | No login at all; requests are proxied so they look like they come from DuckDuckGo, with IP and metadata stripped |
| Encryption model | Encrypted in transit and at rest; privacy enforced by policy | Also not end-to-end; a few models (e.g. gpt-oss-120b via Tinfoil) run in a trusted execution environment so the host can't see prompts |
| Ads & behavioural tracking | No ads, no ad pixels, no cross-site profiling | No ads, no tracking (DuckDuckGo's core stance) |
| Model choice | A fast frontier model via a model picker, with more options over time | Broad multi-provider choice — models from OpenAI, Anthropic, Mistral and Google; more advanced models on paid tiers |
| Persistent history synced across devices | Yes — full history, auto-titled, synced to your account | No — chats live locally on one device only |
| Per-conversation custom instructions & assistants | Yes — per-chat system prompt plus saved reusable assistants (paid) | Not offered — no saved system prompts or personas |
| Organisation (folders, pins, sidebar) | Folders and pinned conversations in a keyboard-first sidebar | Simple local chat list |
| Voice mode | Real-time voice on Pro (~1 hour/month) | Free voice chat within daily caps (no account); recordings not kept after you end it |
| Platforms | Web app only (no native mobile apps yet) | Web (duck.ai) plus the DuckDuckGo browser and mobile apps |
| Pricing & anonymous payment | Free 5/day; Standard $14.99/mo, Pro $45.99/mo; optional anonymous crypto pass (no card, no name) | Generous free tier; higher limits/advanced models via DuckDuckGo's paid plan from ~$9.99/mo |
Where Duck.ai genuinely wins
Duck.ai is one of the strongest free, anonymous ways to use frontier AI, and it's honest to say so.
Anonymous by design
There's no account and no login. DuckDuckGo acts as a proxy: it strips your IP address and other identifying metadata, so requests reach providers like OpenAI, Anthropic, Mistral and Google looking like they came from DuckDuckGo rather than you. Evenfall, by contrast, requires an account.
Nothing stored server-side
Duck.ai doesn't record your chats on its servers. Recent conversations are saved locally on your device and can be cleared or switched off entirely, and providers agree to delete data once it is no longer needed to answer you (at most within about 30 days, with limited safety and legal exceptions). A few models even run inside a trusted execution environment so the inference host can't see your prompts.
Model breadth and price
The free tier alone spans several providers, and paid access to more advanced models starts around $9.99/month — cheaper than Evenfall. If you want maximum anonymity for zero cost, Duck.ai is hard to beat. See our principles for how Evenfall's approach differs.
Where Evenfall is the better fit
Evenfall is a fuller chat product built around privacy by policy rather than anonymity. The trade-off is deliberate: you sign in, and in exchange you get a chat tool you can live in.
History that follows you
Every conversation is saved to your account, auto-titled, and synced across devices, with folders and pinned chats in a keyboard-first sidebar. Duck.ai's local-only storage is great for leaving no trace, but you can't pick a chat back up on another device.
Instructions, assistants, and web search
Evenfall supports per-conversation custom instructions, saved reusable assistants for paid users, and automatic web search when a question needs fresh information (you can turn it off). These stateful, product-style features aren't part of Duck.ai.
Honest privacy, plus anonymous billing
Evenfall never trains on your conversations, runs no ads or tracking, and hard-deletes a conversation's database row on request. Your history is encrypted in transit and at rest and stays synced until you delete it. If paying anonymously matters, a one-time crypto pass needs no card, bank, or name. Compare tiers on pricing.
frequently asked
Does Duck.ai train AI models on my chats?
No. DuckDuckGo says your conversations are not used to train models, and its provider agreements require them to delete data once it is no longer needed to generate a response — at most within about 30 days, with limited safety and legal exceptions.
Is Duck.ai really anonymous?
Largely, yes. Duck.ai needs no login and proxies your requests through DuckDuckGo, stripping your IP address and identifying metadata before they reach the model provider. As of 2026 it is one of the strongest free anonymous AI chat options.
Does Evenfall store my conversations?
Yes. Evenfall keeps your chat history in a normal server-side database so it can sync across your devices, and it stays there until you delete it. Deleting a conversation permanently removes its database row. Duck.ai, by contrast, does not store your chats on its servers.
Which should I choose, Duck.ai or Evenfall?
Choose Duck.ai for free, no-login anonymity and a wide range of models. Choose Evenfall if you want synced history across devices, per-conversation custom instructions, saved assistants, voice mode, and the option to pay anonymously with crypto.
How much do they cost?
Duck.ai has a generous free tier, with more advanced models and higher limits on DuckDuckGo's paid plan from around $9.99/month. Evenfall is free at 10 messages/day, with Standard at $14.99/month and Pro at $45.99/month.
