## David

David is distributed as a Chrome extension and targets a narrow, practical annoyance: filling in the same kinds of web forms again and again. Instead of typing your name, address, preferences and survey answers field by field, the extension detects the inputs on the page and completes them for you.

The publisher describes it as learning and adapting over time, so the more often you use it, the closer its fills get to what you would have typed yourself. Customisable settings give you control over how aggressive the automation is, which matters when a mistake on a checkout page is more costly than a mistake on a survey.

It is a small, single-purpose tool with a very modest install base and English-only interface. If your browser use involves a lot of registration and data-entry screens, it is worth a look; if you rarely touch web forms, there is little here for you.

**Pricing & Plans:** Listed in the Chrome Web Store as freemium. The extension is a free install; no separate subscription price or official pricing page is published.

- **Automatic field completion:** Detects form fields on the page and populates them automatically rather than making you tab through and type each one.
- **Preference learning:** The extension adapts to your preferences and typical answers, so repeated fills need less correction.
- **Customisable behaviour:** Settings let you decide how much the extension does on its own versus how much you review before submitting.
- **Works across registrations and surveys:** Covers registrations, surveys, checkouts and other multi-field web forms rather than one specific site.
- **Lightweight footprint:** The extension is tiny, so it adds negligible browser overhead.

**Strengths:** Very small download (about 61 KB) with minimal browser overhead; Handles the repetitive part of registrations, surveys and checkout forms; Adapts to your preferences so fills improve over time; Settings let you keep control over what it fills automatically

**Limitations:** Only around 20 installs and zero ratings, so maturity is unproven; English-only interface; Stores and reads page content to function, which some users will weigh carefully; No published pricing page or dedicated website, only the store listing

## 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
