## BoltAI

BoltAI is a native macOS application built with SwiftUI and AppKit rather than a wrapped web page, which shows in its responsiveness and in details like universal shortcuts and Apple silicon performance. The core idea is consolidation: instead of juggling browser tabs for ChatGPT, Claude and Gemini, you configure each provider once and switch between more than 300 models from a single window, including local models served through Ollama or LM Studio.

Beyond chat, BoltAI leans into power-user workflows. Projects and multi-chat threads keep long research organised, chats can be forked to explore alternative directions, reusable agents carry custom instructions, knowledge and tools, and MCP servers can be connected and toggled per agent. Multimodal support means you can attach PDFs, screenshots or code and ask for summaries, explanations or structured extraction. A global hotkey pops the app over any window, while screen capture, dictation and inline editing keep you in the flow of whatever else you are doing.

Privacy is a structural part of the design: conversations are stored locally and not used for training, and API keys can be encrypted with a passphrase. Licensing is a one-time purchase with a year of updates, after which the installed version keeps working on your Mac. Older chats remain available while cloud sync and mobile access pause if you do not renew.

**Pricing & Plans:** One-time purchase with a perpetual licence and one year of updates included; after the first year the desktop app keeps working locally, while cloud sync and mobile access require the update plan. A free trial is available without an account, and AI usage is billed separately by your own model providers.

- **300+ models in one app:** Switch between OpenAI, Anthropic, Google Gemini, Mistral, Azure, Amazon Bedrock and local Ollama or LM Studio models without changing applications.
- **Agents, projects and forking:** Build reusable agents with custom instructions, knowledge and tools, organise work into projects and multi-chat threads, and branch a chat to compare alternative answers.
- **Multimodal analysis and screenshots:** Attach PDFs, documents and screenshots, use the screen-capture-to-answer flow, and get summaries, explanations or structured data extraction from vision-capable models.
- **Tools, MCP and local privacy:** Connect local and remote MCP servers, enable code execution and attached knowledge, while chats stay on-device and API keys can be passphrase-encrypted.
- **Global shortcut and dictation:** Summon the app over any window with a keystroke, dictate prompts, and edit selected text inline without leaving your current task.

**Strengths:** Genuinely native macOS performance rather than an Electron wrapper, with universal shortcuts and Apple silicon optimisation; Provider-agnostic: one interface across all major cloud models plus local inference, avoiding subscription lock-in; Strong privacy posture with local chat storage, no training on your data and optional API key encryption; Advanced power-user tooling — agents, MCP servers, chat forking, context profiles and fine-grained generation controls

**Limitations:** You must supply and pay for your own API keys; the app does not bundle AI credits; One-time licence covers a year of updates, and cloud sync plus mobile access pause if you do not renew; Feature depth aimed at power users means a steeper learning curve for casual users

## 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
