Predicts the next code edit in real-time by indexing the entire project locally and analyzing surrounding context, delivering suggestions in milliseconds via a custom-trained 'Tab model' that learns from your codebase patterns. Suggestions are accepted by pressing Tab, enabling rapid code generation without context switching. Uses semantic understanding of code structure rather than simple pattern matching to generate contextually appropriate completions.
Unique: Uses custom-trained 'Tab model' fine-tuned on individual codebase patterns via local indexing, enabling millisecond-latency suggestions without sending code to cloud during inference; Privacy Mode option ensures code never leaves the IDE for training or storage
vs alternatives: Faster than Copilot for autocomplete because suggestions are generated locally from indexed codebase rather than sent to cloud API, and custom model training on your code patterns produces more contextually relevant suggestions than generic LLM-based completers
Enables searching across the entire indexed codebase using natural language queries (e.g., 'payment processing') rather than regex or keyword matching. Converts natural language intent into semantic embeddings and matches against indexed code embeddings to surface relevant functions, classes, and files. Results are ranked by semantic relevance and presented with code snippets and file locations.
Unique: Indexes entire codebase locally and performs semantic search via embeddings rather than keyword/regex matching, allowing natural language queries like 'payment processing' to surface relevant code without knowing exact identifiers; integrates directly into IDE search UI
vs alternatives: More powerful than IDE's built-in text search because it understands semantic meaning of code rather than literal string matching, and faster than web-based code search tools because indexing is local and doesn't require uploading codebase
Implements a flexible pricing model where autocomplete is unlimited on paid plans, but advanced features (code generation, chat, code review, web search) consume API credits. Free tier includes 1,000 autocompletes and $5 API credits; paid tiers ($10-60/month) include unlimited autocomplete and varying API credit allowances. Operates by tracking feature usage and deducting credits per request, with optional automatic top-up for continuous usage.
Unique: Separates unlimited autocomplete from credit-based advanced features, allowing developers to use core functionality without cost while controlling spending on premium features — unlike flat-rate competitors (Copilot $10/month unlimited, Codeium variable pricing)
vs alternatives: More flexible than flat-rate pricing because developers only pay for advanced features they use; more transparent than per-request pricing because credit allocation is clear; better for cost-conscious users because autocomplete is unlimited
Analyzes differences between code branches (e.g., feature branch vs. main) and provides automated review feedback on changes, identifying potential issues, style violations, and improvement suggestions. Uses the indexed codebase context to understand how changes fit into the broader codebase patterns and conventions. Review results are presented inline in the IDE with actionable suggestions.
Unique: Performs code review using codebase-aware context from local indexing, enabling review feedback that understands project conventions and patterns rather than generic linting rules; integrated directly into IDE workflow without requiring external PR platform
vs alternatives: More context-aware than GitHub's native code review because it understands your specific codebase patterns and conventions, and faster than human review because it provides immediate feedback without waiting for reviewer availability
Enables browsing the web and fetching external content (documentation, API references, Stack Overflow answers) directly from the IDE without context switching. Queries are processed by Sweep's backend, results are fetched and summarized, and relevant information is presented inline. Supports OAuth 2.0/2.1 for authenticated access to restricted content. Added in v1.24 (Oct 6, 2025).
Unique: Integrates web search directly into IDE workflow with OAuth 2.0/2.1 support for authenticated content, allowing developers to fetch and read external resources without leaving the editor; backend handles search and content fetching while IDE displays results inline
vs alternatives: Reduces context switching compared to opening a browser, and supports authenticated content access (via OAuth) that generic web search tools don't provide; tighter integration with IDE than browser extensions
Resolves code definitions (function declarations, class definitions, variable assignments) across the indexed codebase and enables navigation to their source locations. Uses semantic understanding of code structure to identify definition locations even in complex inheritance hierarchies or dynamic code patterns. Integrates with IDE's 'Go to Definition' functionality to provide enhanced navigation with codebase context.
Unique: Uses codebase-aware indexing to resolve definitions with semantic understanding of code structure, enabling accurate navigation in complex inheritance hierarchies and dynamic code patterns where IDE's built-in resolution fails; integrates seamlessly with IDE's native 'Go to Definition' UI
vs alternatives: More reliable than IDE's built-in definition resolution for dynamically-typed languages and complex code patterns, and faster than manual searching because definitions are pre-indexed and resolved in milliseconds
Connects to remote Model Context Protocol (MCP) servers to extend Sweep's capabilities with custom tools and data sources. Supports OAuth 2.0/2.1 authentication for secure access to remote servers. Enables integration with external services (databases, APIs, custom tools) without embedding credentials in the IDE. Added in v1.27 (Dec 1, 2025).
Unique: Implements MCP server integration with OAuth 2.0/2.1 support, enabling secure connection to remote tools and data sources without embedding credentials; allows Sweep to be extended with custom capabilities beyond built-in features
vs alternatives: More secure than hardcoding API keys in IDE configuration because OAuth tokens are managed by remote server; more flexible than built-in tool set because MCP protocol allows arbitrary tool definitions
Indexes the entire project codebase locally, creating semantic embeddings and metadata for all code artifacts (functions, classes, files, patterns). Indexing is performed on-device in Privacy Mode or via cloud backend in standard mode. Indexed data enables fast semantic search, context-aware autocomplete, and code review without re-analyzing code on each operation. Index is updated incrementally as code changes.
Unique: Supports dual-mode indexing: Privacy Mode for local-only indexing with zero cloud data transmission, or cloud-backed indexing for faster operations; enables all downstream capabilities (search, autocomplete, review) to work with pre-computed semantic embeddings rather than analyzing code on-demand
vs alternatives: Privacy Mode provides stronger privacy guarantees than cloud-only indexing services like GitHub Copilot, and local indexing enables faster operations than cloud-based alternatives because embeddings are pre-computed and cached locally
