## 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

## Voiceform

Most survey tools force a trade-off: closed questions scale cheaply but capture shallow signal, while qualitative interviews produce rich detail but require a moderator for every session. Voiceform attacks that trade-off directly. You build an interview from multiple choice, Likert, matrix, checkbox, dropdown, and open-ended questions, choose whether respondents answer by voice, video, or text, add branding and conditional logic, and then launch the same interview to thousands of people simultaneously. The AI moderator asks dynamic follow-ups when an answer is vague, which is the part that normally requires a human researcher in the room.

Analysis is where the automation pays off. Responses arrive transcribed, translated, and themed without manual coding, with sentiment scoring and charts ready to export. The platform advertises more than 50 languages, so a single study can span global audiences, and results can be pushed to CSV, Excel, or audio downloads in MP3 and WAV. Teams can either bring their own participants through a shared link or embed, or draw on Voiceform's screened respondent pool.

For larger organizations there is an enterprise story: SOC 2 Type 2 and HIPAA compliance, SSO, two-factor authentication, role-based access controls, an API and SDK with sub-500ms responses and webhooks, and a stated 99.99% uptime target. Integrations connect findings to thousands of other tools, and case studies cite results such as 500 interviews in 72 hours, four times completion rates, and markedly longer open-ended answers. Pricing is quote-based through a demo or sales conversation, with a free trial entry point.

**Pricing & Plans:** Contact for pricing. Voiceform offers a free trial and routes paid plans through a demo or sales conversation; enterprise terms cover compliance, SSO, and API/SDK access.

- **AI-moderated interviews:** An AI moderator generates dynamic follow-up questions when an answer is thin, adding interview depth without a human moderator per session.
- **Voice, video, and text responses:** Respondents can answer by speaking, recording video, or typing, and teams can embed the same questions into existing survey platforms.
- **Automatic analysis pipeline:** Every response is transcribed, translated, and themed with sentiment scoring and charts ready to drop into a report.
- **50+ language support:** Built-in AI translation and transcription let one study reach audiences across more than fifty languages.
- **Enterprise controls and API:** SOC 2 Type 2 and HIPAA compliance, SSO, two-factor authentication, role-based access, and an API/SDK with webhooks and sub-500ms latency.

**Strengths:** Combines interview depth with survey scale in one workflow; Transcription, translation, sentiment, and theming happen automatically; Highly customizable question types, branding, and conditional logic; Enterprise-grade compliance, SSO, and a low-latency API and SDK

**Limitations:** No public price list; you need a sales conversation to get numbers; AI moderation quality still benefits from human review of themes and edge cases; Voice and video responses are inherently more effortful for respondents than plain text forms
