## mymind

mymind bills itself as "the extension for your mind." The core idea is frictionless capture: you save notes, links, images, quotes, articles, PDFs and even short videos with a click or a tap, and the app figures out the rest. There are no folders to design and no tag taxonomies to maintain — the platform detects whether an item is an article, a product, a book or a recipe, then files it visually so your saved library looks more like a mood board than a filing cabinet.

The AI layer is what replaces manual organization. On paid tiers you get automatic image tagging, text recognition inside screenshots and memes, article and PDF summaries, and Smart Spaces that group related saves around a theme without any setup. Search is deliberately associative: you can look for something by color, brand, keyword or approximate date, which mirrors how people actually recall things. Mastermind subscribers also get Reading Mode, full article backup even if the source disappears, bidirectional linking between notes, and video uploads up to 500 MB each.

mymind leans hard into privacy as a differentiator. There are no social features, no vanity metrics, no ads and no data selling; the company describes itself as a small indie team with no outside funding whose work is paid for entirely by members. Apps exist for iOS, Android, macOS and major browsers, with syncing across all of them. Pricing is straightforwardly subscription-based, with a basic Bookmarker tier for people who just want beautiful bookmarks and no AI.

If you need team collaboration, shared workspaces or enterprise admin controls, mymind is intentionally the wrong tool — it is designed for one person's private mind.

**Pricing & Plans:** Subscription with a free trial. The Bookmarker is $4.99/month; Student of Life is $7.99/month or $79/year; Mastermind is $12.99/month or $129/year (yearly saves roughly 20%). A not-yet-released "Newton" plan at $299/year is listed as in development.

- **Zero-organization saving:** Save notes, links, quotes, images, articles, PDFs and videos in one click, and let mymind categorize them automatically instead of building folder structures.
- **Associative visual search:** Find saved items by color, brand, keyword or date. Image text recognition even lets you search words that appear inside screenshots, memes or handwriting.
- **AI tagging, summaries and PDF analysis:** Images get tagged automatically, and Mastermind members get paragraph summaries of articles, web pages and PDFs so old saves are still useful months later.
- **Smart Spaces and Same Vibe:** Smart Spaces auto-group saves around a search, theme or tag, while Same Vibe builds a mood board from images you already saved with a similar look and feel.
- **Private by design, synced everywhere:** No ads, no analytics-driven feeds, no data selling; your library syncs instantly between iOS, Android, macOS and browser extensions.

**Strengths:** Removes the ongoing chore of folders, labels and tag upkeep; Strong privacy stance with no ads, no social layer and an explicit no-data-selling promise; Excellent associative recall through color, brand, keyword and in-image text search; Native apps for iOS, Android, macOS and all major browsers with reliable cross-device sync

**Limitations:** Paid-only beyond the trial — there is no permanent free tier; Built for individuals, so no shared workspaces, team permissions or collaboration features; Blue-chip AI features such as summaries, article backup and video upload require the higher Mastermind plan

## 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
