## Bookmarker

Bookmarker is a desktop app built for people who save a lot and lose a lot. Instead of spreading bookmarks across browser folders, screenshot albums and a downloads folder full of PDFs, you drop everything into one library that lives in a local database on your Mac. Each save opens in a clean reading view, and a full-text search lets you find any of it offline, in a fraction of a second.

The intelligence layer runs on the machine itself. Using Apple Foundation Models, Bookmarker tags and summarizes every item you save, so your library organizes itself without you building folder hierarchies. If you want heavier image understanding, you can plug in your own Gemini API key and pay the model provider directly at cost.

Privacy is the organizing principle rather than a feature. There is no account, no sign-up, no cloud sync and no telemetry by default; your data stays in a local database until you deliberately add a cloud key. Small extras round it out: color palette extraction from any image with one-click hex copy, inline highlights and annotations in PDFs and articles, and one-click import from Raindrop, Pocket, browser bookmark exports or a folder of PDFs. It is sold as a one-time purchase with free updates, and requires macOS 13 or newer on Apple Silicon.

**Pricing & Plans:** One-time purchase of $99 with free updates; a full-featured 14-day trial is available without an account or credit card. Cloud image vision is optional and billed by your own Gemini key at provider cost.

- **On-device AI tagging and summaries:** Apple Foundation Models run locally to tag and summarize every link, image and PDF you save, so your library organizes itself with no setup and no cloud round-trip.
- **Offline full-text search:** Search the text of every article, note and PDF in your library instantly, even with no connection.
- **One library for links, images and PDFs:** Save a URL, a screenshot or an entire folder of documents the same way, and read any of them in a clean, ad-free reading view.
- **Privacy by architecture:** No account, no cloud sync and no tracking. Everything lives in a local database on your Mac unless you deliberately bring your own API key.
- **Highlights, annotations and palette extraction:** Mark up PDFs and articles inline, and pull a full color palette out of any image with one-click hex copying for design work.

**Strengths:** Truly local-first: no account, no sync, no telemetry, data stays on your disk; One-time $99 purchase instead of an open-ended subscription; On-device AI tagging and summaries work without an internet connection; Fast offline full-text search across links, notes and PDF text

**Limitations:** Apple Silicon only (M1 or newer) and requires macOS 13+, so older Intel Macs are unsupported; No cross-device sync at all, which is a blocker if you work across several machines; Upfront $99 cost is high compared with cheap cloud bookmark services; Cloud image vision requires you to obtain and manage your own Gemini key

## Consensus

Consensus works like a scholarly search engine supercharged by AI. Instead of returning a flat list of PDFs, you ask a natural-language research question and Consensus extracts claims from relevant papers, then shows you what the studies actually find. A Consensus Meter summarizes the weight of evidence for yes/no questions, so you can see at a glance whether scientists largely agree, disagree, or remain divided.

The platform indexes hundreds of millions of peer-reviewed papers spanning medicine, biology, psychology, economics and more. Answers link straight back to the source studies, and you can filter by study design, journal quality, sample size and publication year to separate stronger evidence from weaker signals. Features like Deep Search, Topic Synthesis and Skills let researchers build a working knowledge base over time rather than starting from scratch on every query.

Consensus is designed for researchers, clinicians, students and analysts who need trustworthy signals from the scientific record without drowning in irrelevant results. A free tier gives limited AI-powered searches each month, while paid plans unlock unlimited use, advanced filters and deeper synthesis.

**Pricing & Plans:** Freemium. A free tier offers a limited number of AI-powered searches per month; paid individual plans unlock unlimited searches and advanced research features, with discounted student pricing and team/enterprise options.

- **Evidence-grounded answers:** Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
- **Consensus Meter:** A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
- **Powerful filters:** Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
- **Topic synthesis and Deep Search:** Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
- **Research workspace:** Save papers, organize sources and build a persistent knowledge base for literature reviews and ongoing projects.

**Strengths:** Answers cite real peer-reviewed papers, so claims are verifiable; Consensus Meter makes it easy to gauge scientific agreement at a glance; Rich filters help separate high-quality evidence from weaker studies; Fast, clean interface designed around research workflows

**Limitations:** Free tier caps the number of AI-assisted searches per month; Coverage is strongest for STEM and health fields, lighter for some humanities topics; It guides you toward sources but is not a substitute for reading full papers
