## Dewey

Dewey turns the most-used app on your phone — your messaging inbox — into a lightweight accountability system. Instead of installing yet another productivity tool you will ignore, you text Dewey the way you would text a friend: what you want to get done, when it matters, and what tends to get in the way. Dewey replies with reminders, check-ins and follow-up questions that keep the commitment front of mind.\n\nThe product sits at the intersection of an AI assistant and a human-style accountability coach. Because everything happens in SMS, there is no dashboard to learn, no notification settings to tune and no separate app to open. The conversation is the interface, and the cadence adapts to what you tell it about your schedule.\n\nDewey positions itself for people who respond better to being asked than to being reminded — the classic accountability-partner dynamic, minus the need to find a partner. Pricing is structured around a conversation with the team, so plans are tailored rather than listed publicly.

**Pricing & Plans:** Dewey does not publish a public price list; the site directs prospective users to reach out, so pricing is best confirmed directly with the team.

- **SMS-first design:** Everything runs through text messaging, so there is nothing new to install and no dashboard to check.
- **Goal and habit check-ins:** Tell Dewey what you are working toward and it follows up at the cadence you choose.
- **AI-generated nudges:** Messages are written to feel like a supportive buddy rather than a robotic reminder bot.
- **Accountability follow-through:** Dewey asks what happened and pushes gently on commitments that slipped.

**Strengths:** Zero learning curve because it lives in your messaging app; Feels conversational rather than like enterprise task software; Works on any phone that can send an SMS

**Limitations:** No public pricing page, so you must contact the team first; Capabilities are intentionally narrow compared with full task managers

## 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
