## LanguageTool

LanguageTool is one of the most widely used writing assistants, trusted by thousands of organizations and millions of users. Paste text or type directly into the editor and it highlights grammar, spelling and punctuation mistakes as you write, suggesting corrections in real time. Its "Picky Mode" and style suggestions go beyond basics to catch overused phrases, redundant words and awkward phrasing.

It works where you write. Browser add-ons for Chrome, Edge, Firefox, Safari and Opera check text across any website or email, while integrations for Google Docs, Microsoft Word, LibreOffice, Gmail, Outlook and dedicated Windows and macOS apps cover office workflows. LanguageTool also functions as an international spell checker, automatically detecting the language you are using and supporting regional variants such as US, UK and Australian English.

Beyond proofreading, LanguageTool includes a paraphrasing tool that rewrites sentences to sound more formal, fluent, simple or concise. A free tier covers spelling and basic checks, while Premium unlocks unlimited paraphrasing, advanced style suggestions and personal dictionaries. Organizations can deploy GDPR-compliant LanguageTool for Business for consistent brand voice across teams.

**Pricing & Plans:** Freemium. A free version handles spelling and basic grammar, while Premium unlocks unlimited paraphrasing, advanced style checks and more suggestions. LanguageTool for Business adds team and enterprise features.

## Models.dev

Models.dev exists to answer a very practical developer question: which model should I use, and what will it cost? The site organises every entry under a canonical identifier in the form provider/model, so the same model served by several providers can be compared directly rather than guessed at. Columns cover context window, maximum output, whether input and output are supported, reasoning, tool calling, structured output, temperature control, open versus closed weights, price per million tokens, and release and update dates.

Because model releases move fast, the catalogue is built to stay current, with sortable and searchable tables that let you scan by lab or provider and filter down to what matters. Entries include both closed flagship models and open-weight alternatives, making it useful for cost planning as well as capability research.

The project is open source and free to use, and it is intended to be consumed programmatically. Developers can pull the catalogue into their own tooling through a JSON API or a type-safe SDK, which makes it a practical backend for dashboards, routing logic, or internal cost calculators rather than just a reference page to browse.

**Pricing & Plans:** Models.dev is free and open source. It is a reference database, so the prices it lists are the per-million-token rates charged by the model providers themselves, not a fee for using the site.

- **Canonical model identifiers:** Every model uses a consistent provider/model format so the same model across providers can be compared directly.
- **Specification comparison:** Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
- **Pricing transparency:** Input and output prices per million tokens listed alongside release and update dates.
- **Open and closed models:** Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
- **Developer access:** Consume the catalogue through a JSON API or a type-safe SDK for your own tools and dashboards.

**Strengths:** Free and open source with no account required; Consistent canonical identifiers make cross-provider comparison reliable; Covers pricing, limits, and capabilities in one sortable table; Available as a JSON API and type-safe SDK for programmatic use

**Limitations:** It is a reference catalogue, not an inference or hosting service; Data quality depends on community and maintainer updates keeping pace with releases; Interface is aimed at developers and offers little guidance for non-technical users
