## Open Knowledge Maps

Open Knowledge Maps, often shortened to OKMaps, is an open-science platform whose mission is to dramatically increase the visibility of research findings. Rather than returning a ranked list of links, it builds an interactive knowledge map from your search terms: related items are grouped into bubbles and color-coded clusters, so you can immediately see which subtopics exist and which of them matter most to your question. Clicking a cluster expands it, and each node links out to the underlying metadata and source record.

The service queries BASE, one of the world's largest open repositories aggregators, covering more than 400 million outputs from over 11,000 sources, including publications, datasets, software, and images. Because the visual layout is generated directly from the metadata rather than from generated text, the project emphasizes that results contain no hallucinations. Everything is delivered in a browser, requires no installation and no account, and the underlying software is open source on GitHub.

Open Knowledge Maps is operated as a charitable non-profit organization. It is free for anyone to use and sustains itself through supporting members such as university libraries, plus grants and donations. It also offers custom services so institutions can embed its discovery components into their own search portals. The result is infrastructure aimed at students, researchers, librarians, and curious non-specialists who want a faster, more intuitive entry point into a field.

**Pricing & Plans:** Free for all users. Open Knowledge Maps is a charitable non-profit funded by supporting members (libraries and institutions), grants, and donations, with optional paid custom-integration services for organizations.

- **Visual knowledge maps:** Every search produces an interactive concept map in which related research outputs are grouped into labeled, clickable clusters instead of a single flat list.
- **400M+ research outputs:** Searches more than 400 million records in over 400 languages pulled from more than 11,000 sources through the BASE aggregator.
- **25 output types:** Beyond journal articles, results span datasets, software, images, and other research objects, giving a broader picture of a topic.
- **No AI hallucination:** Maps are generated from metadata rather than synthesized text, so what you see corresponds to real indexed records.
- **Open source and embeddable:** The platform is open source on GitHub, and institutions can integrate its discovery components into their own systems via custom services.

**Strengths:** Completely free with no account or installation required; Visual clustering makes the structure of a topic obvious at a glance; Nonprofit, open-science mission with an open source codebase; Metadata-driven results avoid the hallucination risk of text-generating search tools

**Limitations:** Coverage is limited to what is available through the BASE aggregator; Map quality depends on how specific your search terms are; No built-in full-text reading, saving, or personal library features

## Ultimaps

Ultimaps is an online map maker built for people who have data in a spreadsheet and need it on a map without learning GIS. You begin by selecting one of more than 200 pre-built vector maps — the world, a continent, any country, US states, individual states by county, or ZIP codes — each split into administrative regions you can color individually. From there you either shade regions by hand or bring in data by pasting from Excel, uploading a CSV, connecting Google Sheets or Notion, or typing a natural-language prompt like "color states by population." The tool matches your values to the right regions even when the formatting is messy, then generates a color scale and legend automatically.

For shareable output, Ultimaps converts any map into a live, embeddable experience. Tooltips and popups are populated from your data columns, so a single template covers every region, and visitors can hover, click through links, and pan or zoom. Publishing produces a shareable link or an embed code; in Notion, WordPress, Ghost and Substack you can simply paste the link and it renders as the live map, with edits reflected after publishing and no new code to re-paste. Static exports cover high-resolution PNG, SVG and PDF for reports, slides and print.

The platform also advertises an integration that lets users make maps from their data inside ChatGPT, plus quick single-purpose tools such as Color a Map, Map Maker, US Map Maker and ZIP Code Map Maker. Pricing is freemium: unlimited maps and importing are free, free PNG exports carry a small credit, and the Pro plan removes branding, unlocks vector and 6x-resolution exports, adds templates, duplicates, larger lookup and AI request allowances, and includes priority support. Custom maps for regions Ultimaps does not cover are available as a paid service. The company reports 25,000+ monthly users and a 4.8 out of 5 rating from 72 reviews.

**Pricing & Plans:** Freemium. The Free plan offers unlimited maps with Excel, CSV, Sheets and Notion imports, 100 address lookups and 20 AI requests per month, and PNG export with a small ultimaps.com credit. Pro (roughly EUR41.58/month billed yearly, around EUR49 monthly) adds unbranded exports, 6x-resolution PNG plus SVG and PDF, unbranded interactive maps, 5,000 lookups and 500 AI requests monthly, and priority support. Custom plans and single-map exports (about EUR12.50 per map) are also offered.

- **200+ Ready-Made Vector Maps:** Choose from world, continent, country, US state, county and ZIP code maps, each divided into regions you can color individually.
- **Spreadsheet & AI Data Import:** Paste from Excel, upload CSV, connect Google Sheets or Notion, or type a prompt like "color states by population" and let the AI map it.
- **Automatic Scales and Legends:** Smart color scaling picks palettes and breakpoints for your dataset and generates a matching legend without manual configuration.
- **Interactive Embeds:** Publish a live map with tooltips, popups, click-through links, pan and zoom, then embed it via one line of code or by pasting the link into Notion, WordPress, Ghost or Substack.
- **Pins and Annotations:** Geocode addresses into pins, group nearby locations with numbered markers, add annotations, and color-code regions by category or value.

**Strengths:** Very low friction: no account needed to start and no GIS skills required; Imports directly from Excel, CSV, Google Sheets and Notion with fuzzy region matching; Automatic color scales and legends save manual design work; Interactive embeds with tooltips and popups work across major CMS platforms

**Limitations:** Publishing interactive maps and unbranded exports require a paid tier; Free interactive maps display a small ultimaps.com credit; Free plan caps address lookups and AI requests each month; Advanced custom regions and themes need a bespoke arrangement
