## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans

## String Catalog

String Catalog keeps localization inside source control instead of spreading it across spreadsheets and side tools. You connect the repository you already ship from, choose the branch you release from, and String Catalog proposes translation updates as clean diffs that your team reviews and merges like any other change. Native formats stay native: .xcstrings files for Apple platforms and Android strings.xml both round-trip without hand cleanup or one-off scripts.

The product deliberately covers more than raw strings. App Store and Google Play release notes and store listing copy can be prepared in the same workspace, with platform-specific field limits, locale codes, and exportable output that growth teams can ship directly. Tone guidance, protected brand terms, and glossaries travel with every new language so the result sounds like your app rather than a generic machine translation.

Quality control is built into the loop. Reviewers get secure no-login links, suggested fixes appear in review queues, and low-confidence output can be retried before release week. Pricing is deliberately flat across languages: every plan covers up to 40 languages, so cost depends on string volume and workflow needs rather than how many markets you enter.

**Pricing & Plans:** Paid subscription with a monthly or annual option (annual saves about 20%) and one free language to trial. Published plans are Hobby at $15/month, Pro at $45/month, and Business at $75/month, differing mainly by base string-key limits and review features. All plans include up to 40 languages and no per-language charge. Check the site's cost calculator for current figures.

- **Git-native, reviewable workflow:** Connect GitHub, GitLab, or Bitbucket and receive localization updates as pull requests and clean diffs on the branch you release from, so your repository stays the single source of truth.
- **Native format support:** Round-trip .xcstrings for Apple platforms and Android strings.xml without spreadsheet export, broken builds, or custom scripts.
- **Release notes and store metadata:** Translate App Store and Google Play release notes and store listing copy in the same product, with platform-specific field limits and locale handling.
- **Brand voice and glossary controls:** Protect brand terms, add tone guidance, and reuse glossaries so each new locale keeps the product voice users already know.
- **Human review with secure links:** Share no-login review links, inspect suggested fixes in review queues, and bulk-accept edits when a translation needs more than an automatic pass.

**Strengths:** Stays inside the Git workflow teams already trust, with pull requests and clean diffs instead of silent content mutation; Flat pricing across up to 40 languages removes per-locale cost math and makes adding markets predictable; Covers strings, release notes, and store metadata in one product instead of three separate tools; Human review tooling, protected terms, and tone guidance are included rather than bolted on

**Limitations:** Built primarily around iOS and Android app workflows, so web or backend-only projects may find it a tight fit; Review quality features such as shared review links and accuracy monitoring are limited to higher-priced Pro and Business plans; Base string-key ceilings on each tier mean very large apps need to size plans carefully or move up a level
