The Problem

Academic research is broken for everyone except academics

Publicly funded research sits behind paywalls, buried in jargon, discussed only in academia. The knowledge exists. The audience exists. The bridge doesn't.

🔒
Most research is paywalled
Journals charge $30–50 per article. Publicly funded research, locked from the public.
📖
The rest is unreadable
Open access papers are written for specialists. A PhD is often needed just to understand the abstract.
💬
Discussion happens nowhere
Twitter threads, obscure forums, private emails. No structured home for public engagement with research.
⚠
Bad science spreads unchecked
Preprints go viral before peer review. Retractions go unnoticed. Nobody is watching.
Who Is Annotia For?

If you care about what the research says,
this is for you.

👩‍⚕️
Clinicians & Practitioners
Stay current with evidence-based practice without reading 40-page papers. Get the findings that matter for your patients.
🔬
Researchers & Academics
Discover papers across disciplines, see what the community thinks, and join structured discussions with source-backed claims.
🎓
Students & Curious Minds
Understand real research without a PhD. AI analysis break down the jargon so you can engage with science on your terms.
What Annotia Does

Everything a paper deserves.
Nothing it doesn't.

✦
AI-Powered Paper Summaries
Every paper gets an AI analysis: methodology assessment, key findings, confidence analysis, and a jargon guide. All clearly labelled as AI-generated.
⚑
Transparent & Correctable AI
Every AI output is labelled "AI-generated · Always verify against source." Flag button on every analysis. Community reports inaccuracies, flagged content gets corrected. AI is a starting point, never the final word.
◎
Structured Discussion
Threaded comments on every paper. Flag errors in AI analysis. Upvoting surfaces quality, not just popularity. Get notified when someone replies or new discussion starts on a paper you follow.
📊
Community Confidence Score
Every paper carries a live confidence score based on peer review status, sample size, community flags, and methodological quality. One number that tells you how much weight to give a finding.
🔄
Retraction Tracking
When a paper is retracted, its page is flagged, saved users are notified, and the confidence score updates. Bad science doesn't quietly disappear — it gets marked.
⚡
Preprint Pipeline
New papers from PsyArXiv, bioRxiv, arXiv and medRxiv added daily with clear preprint warnings. Join the conversation when research drops, not months later.
How It Works

From dense paper to rich discussion
in seconds

01
Paper is added
Via DOI lookup or our daily preprint pipeline. Metadata, authors, and status are automatically fetched from public sources.
02
AI reads it
Claude generates a structured summary — methodology assessment, key findings, confidence analysis, and a jargon guide. Every summary is clearly labelled as AI-generated.
03
Community corrects
AI is fallible. Every summary can be flagged by the community for inaccuracies, missing context, or bias. Flagged summaries are reviewed and corrected — the community is the final authority, not the model.
04
Discussion deepens
Researchers, students, and curious readers discuss the paper. Source citations back up claims. Upvoting surfaces quality. The conversation grows richer over time.
05
Confidence updates live
The community confidence score evolves as discussion deepens, flags are raised, and the paper moves through peer review.

Our Commitments

Built on trust.
Transparent by design.

AI is always labelled

We will never host or link to paywalled content. Every paper on Annotia is legally freely available. Full stop.
Community-driven quality
Every AI analysis can be flagged and corrected. Upvoting surfaces quality commentary. The community holds the platform accountable.
Preprints are always flagged
No unreviewed paper appears without a prominent warning. Clarity is non-negotiable.
Why We Built This

Our roots in open science

Annotia didn't emerge in a vacuum. It was inspired by a growing global movement to make publicly funded research genuinely public — and to use AI responsibly in the process.

United Kingdom
Open Science Mandate
If the public pays for science, the public should read it. Annotia extends this — open access is not enough if the language remains closed.
Netherlands
NARCIS Platform
NARCIS proved a national-scale open research portal could work. Annotia adds AI analysis and community discussion, turning a research index into a living conversation.
Finland
AI Transparency Principles
AI should be explainable, accountable, and clearly identified. These principles shaped Annotia — every output is labelled, flaggable, and community-corrected.
