## Flexnote

Flexnote organizes notes as cards placed freely on an infinite canvas rather than in a linear document. You can zoom, drag, and rearrange them, or view the same board as a mind map, while typing @ creates bidirectional links that turn loose cards into a connected knowledge network. A tag-based database view lets the same cards double as a task list, book library, or web-clipper archive.

Annotation is a core workflow. PDFs and videos can be dropped onto the canvas to highlight, comment, and generate linked knowledge cards; video annotations support timestamped notes from major platforms, so a quote in a lecture links straight back to the moment it came from. Sharing is one click — any canvas becomes an interactive webpage with optional password protection and no account needed for viewers.

Unlike cloud-first tools, Flexnote stores files on your device by default and is fully usable offline. For multi-device work you connect your own storage via WebDAV, Amazon S3, OneDrive, or Baidu Netdisk, and credentials stay under your control. Flexnote AI runs semantic search and knowledge-base Q&A over your notes; chat uses your own model API key, and index points are bundled with Pro plans. A custom rendering engine keeps panning and editing smooth even at 10,000+ nodes.

**Pricing & Plans:** Flexnote has a free plan with 3 whiteboards, 100 cards, core canvas features, and local storage. Pro and Lifetime plans unlock unlimited whiteboards, Flexnote AI smart-index points, and optional cloud sync; during promotional periods a Lifetime license has been offered at a discounted price. See the pricing page for current plans and point quotas.

- **Infinite canvas with mind maps:** Place cards anywhere on the canvas, then switch to mind-map or database views to see structure without reorganizing your notes.
- **PDF and video annotation:** Highlight and annotate PDFs on the canvas and take timestamped notes on videos; highlights automatically become reference cards.
- **Knowledge-base AI:** Semantic search, knowledge-base Q&A, and content retrieval find the right notes; chat works with your own model API key.
- **Local-first with your own cloud:** Files live on your device by default and sync across devices through WebDAV, S3, OneDrive, or Baidu Netdisk — your credentials stay yours.
- **Publish to the web:** Turn any canvas into an interactive webpage with a single link, with optional password protection and no account required for viewers.

**Strengths:** Local-first storage means notes stay on your device and work offline; Combines infinite canvas, mind maps, and databases instead of splitting tools; PDF and video annotation with automatic reference cards is rare in note apps; Sync uses your own WebDAV, S3, or OneDrive accounts, so you keep control of data

**Limitations:** The full web app is not finished; online access is view-only so far; Flexnote AI smart-index points are billed separately from AI chat usage; Advanced publishing and AI features sit behind the Pro or Lifetime tiers

## Semantic Scholar

Semantic Scholar was launched by the Allen Institute for AI as an attempt to solve a very specific problem: scientific output grows far faster than any individual researcher's ability to read it. Instead of matching literal keywords, the platform applies natural-language processing and graph analysis to figure out what a paper is actually about, who it builds on, and which citations inside it mattered — surfacing papers a keyword search would never rank highly.

The catalog spans more than 240 million publications from journals, conference proceedings, preprint servers and repositories, with records combining metadata, abstracts, references, citation counts and extracted entities such as methods, datasets and figures. On top of the core search experience sit features like one-sentence AI TLDRs, Semantic Reader (an augmented PDF reader that surfaces inline citations, definitions and figures while you read), author and venue pages, research feeds, and a Scholar's Hub for tracking the people and topics you care about.

Everything on the site is free to use, and a developer API gives researchers, students and engineers programmatic access to the same corpus — the API now supports paper search, better documentation and improved stability. Because it is a non-profit academic project rather than a commercial product, there is no paid tier: the value proposition is depth of coverage and semantic relevance, not premium features.

**Pricing & Plans:** Completely free. Semantic Scholar is operated as a non-profit academic project by the Allen Institute for AI, with no subscription tiers — accounts, search, Semantic Reader and the developer API are all available at no cost.

- **Semantic search across 240M+ papers:** Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
- **AI-generated TLDR summaries:** Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
- **Semantic Reader:** An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
- **Citation context and influence signals:** See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
- **Free developer API and Scholar's Hub:** A documented public API exposes search and metadata endpoints at no charge, while Scholar's Hub lets you follow authors, topics and citation alerts.

**Strengths:** Free to use with no paywall, subscription or credit limits; Very broad coverage spanning 240M+ papers in all scientific fields; Semantic ranking and AI TLDRs surface relevant work that keyword search misses; Semantic Reader adds inline citations, definitions and figures during reading

**Limitations:** Indexing lag means the newest preprints are not always immediately available; TLDR summaries are machine-generated and can oversimplify nuanced findings; Full text is frequently limited to what publishers or repositories expose; Not a citation manager: no built-in PDF library, BibTeX export workflow or note system
