NOLO next to the other private ones.
Not against the giants that read everything, against the assistants that also take privacy seriously: DuckDuckGo's Duck.ai, Brave Leo, Venice, Proton Lumo and Mistral's Le Chat. Then the real benchmark scores of the models NOLO actually runs, with sources.
Where each one stands.
Based on each company's own public documentation as of June 2026. Their terms can change, so check the source if a detail matters to you.
| NOLO | Duck.ai | Brave Leo | Venice | Proton Lumo | Le Chat | |
|---|---|---|---|---|---|---|
| No account or email | Yes | Yes | Yes | Noemail | Noaccount | Noaccount |
| History stays on your device | Yes | Yes | Yes | Yes | Serverencrypted | Server |

| Real-time web search | Yes | Yes | Yes | Yes | Yes | Yes |
| Image generation | Yes | Yes | No | Yes | No | Yes |
| Voice input | Yes | Yes | Partial | Partial | No | Yes |
| Full interface in 30 languages | Yes | Partial | Partial | Partial | Partial | Partial |

Legend: Yes = supported · Partial / Varies = limited or conditional · No = not offered. Sources: Duck.ai, Brave Leo, Venice, Proton Lumo, Le Chat.
The honest read: several of these are genuinely good, and we're not here to pretend otherwise. Duck.ai and Brave Leo are excellent if you live in their browser or want a quick anonymous question. Proton Lumo encrypts your history on its servers. What's specific to NOLO is the combination: no account at all, history that never leaves your device by default, open-weights models we'll name, and the full toolset (search, files, images, voice, live data, exports) in one private workspace, in 30 languages.
The models NOLO runs, by the numbers.
We don't claim to be the smartest AI on earth, that's not the point of NOLO. But you deserve to know exactly what's under the hood. These are the providers' own published scores on standard public tests, not numbers we made up.
gpt-oss-20b
Free · FastOpenAI's open-weights model (Apache 2.0), same family as gpt-oss-120b. Powers the free plan. Fast, and reasons when asked. Image understanding for uploads runs on a separate shared vision model used across every plan.

gpt-oss-120b
Plus · ReasoningOpenAI's open-weights reasoning model (Apache 2.0). Powers the Plus plan. Built for analysis, planning and harder questions.

DeepSeek V4 Flash
Pro · Long contextAn efficient Mixture-of-Experts model (284B total, ~13B active per token) built for huge documents. Powers the Pro plan. We show its verified architecture rather than borrow the larger V4-Pro's headline scores, because that wouldn't be the model you're actually using.
Source: DeepSeek V4 family specifications (released Apr 2026). Headline reasoning scores like SWE-bench Verified ~80% belong to the larger V4-Pro variant, not Flash.
Same test: GPQA Diamond
Science reasoningSide by side with the open models the other privacy-first assistants actually run. One public test, each maker's own figure. NOLO's models in bright purple.
Those three are the open models behind Duck.ai, Brave Leo, Venice, Le Chat and Proton Lumo. Sources: Meta, Anthropic and Mistral model cards.
Same test: MMLU-Pro
Broad knowledgeProfessional-level knowledge across subjects. Same public test, makers' own published figures.
Mistral Small 3 reports MMLU (81.0), not MMLU-Pro, so we leave it out here to keep the test identical. Sources: Meta and Anthropic model cards.
What these mean: MMLU-Pro tests broad knowledge across professional subjects; GPQA is graduate-level science; AIME is competition math. Different labs run tests slightly differently, so treat cross-model comparisons as a guide, not a photo finish. Every number above is the model maker's own published figure, linked at the source.
Good models. No account. Honest about both.
