PDF readers usually don’t help with pace or focus, so reading long documents becomes slow.

Readly uses two techniques to fix this:

RSVP reading Shows one word at a time on a clean black screen. This removes eye movement completely and keeps your reading pace steady.

Inline spotlight reading Adds a moving highlight bubble directly on the PDF. It guides your eyes word by word, like a focused magnifier, without breaking the document flow.

Other features - Clean focus mode with no distractions - Offline library and resume progress - Custom highlight colors and themes - Quick jumps across long PDFs

Hi HN. I'm the creator of Autism Simulator[1], a choose-your-own-adventure story. I used a library called Inkle for the CYOA logic but I really had to push the limits of the JS implementation of Inkle to get it to accomodate player stats over time (and it was fragile!).

So I've built my own CYOA adventure library.

Palantir Technologies has filed a lawsuit against the CEO of a rival AI firm, alleging a widespread effort to poach its employees. The lawsuit claims the rival company engaged in unlawful tactics to lure away Palantir's talent, including violating non-compete agreements.

Hi HN! We are Klavis AI (https://www.klavis.ai/) and we are launching a managed MCP Sandbox-as-a-Service for RL training on tool use.

If you want a model to learn tool use through RL, you need realistic environments where the model can take actions, you can observe the resulting state, and compute a reward. For SaaS tools, this means managing dozens of test accounts, handling OAuth and token refresh, seeding realistic data for each episode, resetting state between runs, and ensuring isolation when you're running concurrent training sessions. Most research teams spend months building this plumbing per integration.

Klavis is a managed sandbox service that handles all of that. You call our API to get an isolated sandbox backed by a real service instance (not a mock), initialize it with whatever data state you need, let your model interact via MCP, then dump the final state to compute your reward. One more API call resets everything for the next episode.

The key thing is these are real services, not static mocks. When your model creates a calendar event or updates a Salesforce record, that action actually executes against real infrastructure. The state changes are real. This matters because you want training to reflect production behavior exactly.

We currently support 50+ integrations across productivity tools (Google Calendar, Outlook, Slack), CRM (Salesforce, HubSpot), dev tools (GitHub, Jira, Linear), databases (Postgres, Snowflake), and others. We handle the account pooling, auth management, and lifecycle orchestration so researchers can focus on the actual training.

Technically, the workflow is: create a sandbox, call initialize API with a JSON payload defining your starting state, let the model interact via standard MCP tools, call dump API to get a typed snapshot of the final state, compare against your target for reward calculation, then call reset or delete. We use strict Pydantic schemas for all inputs and outputs so malformed data gets rejected immediately rather than causing silent failures mid-training.

Here is a quick demo: https://youtu.be/10C18rpCYcA.

We look forward to your comments. Thanks for reading!
