LanguageTool
What is LanguageTool?
LanguageTool checks grammar, spelling, punctuation, and style in more than 30 languages through a web editor and browser extensions. Paste or type text to get underlined suggestions for subject-verb agreement, comma placement, word choice, and casing, plus a paraphrasing mode that rewrites sentences to be more formal or concise.
Compared with built-in spell checkers that catch typos only, LanguageTool adds over 20,000 extra style and grammar rules on Premium for English, German, French, Spanish, Dutch, Polish, and Portuguese. Picky Mode pushes even further on advanced punctuation and typography, and Premium raises the per-field character limit to 150,000 for long articles or emails.
Writers, students, and teams use LanguageTool inside Chrome, Firefox, Safari, Edge, Google Docs, Microsoft Word, LibreOffice, Slack, and macOS apps. The free Basic tier covers core grammar checks, while Premium and Team plans add shared style guides, team dictionaries, and unlimited AI paraphrasing.
Synthesia
What is Synthesia?
Synthesia turns scripts into presenter-led videos using 240+ stock avatars, cloned voices, and lip-synced dubbing across 160+ languages. You write text, pick an avatar, and export MP4 or SCORM without cameras, studios, or voice actors. The Basic plan includes 10 minutes of generated video per month with 9 stock avatars.
Where most avatar video tools stop at export, Synthesia runs create, localize, collaborate, and publish in one workspace. Embedded videos auto-update when you edit the source, SCORM packages ship with translated versions, and Enterprise teams get Brand Kits plus SAML/SSO. Roleplay Sessions add a newer angle: practice sales or support conversations with interactive avatars that score your responses.
L&D teams use it for compliance and onboarding at scale. Sales enablement groups ship pitch refreshes in minutes instead of booking shoots. Marketing and internal comms teams localize one master video into dozens of languages with one-click translation. Over 50,000 companies use it, including a large share of the Fortune 100.
